Tennis Court Paint, Tennis Court Resurfacing

How Do You Paint A Tennis Court?

If you ask any professional house painter they will tell you, “In hard times, everyone is a painter.”  But if you have ever hired a professional house painter, you will see that they make the job look much easier and better in much less time than the average home owner.  Hiring a professional tennis court painter, or sport surfacing contractor, is the smartest move you will ever make!

Just because it looks like paint and kind of smells like paint, doesn’t mean you apply it the same way.  Tennis court coatings are heavy-bodied and fortified with specialty sand and aggregate.  So, how do you paint a tennis court?  The only good way to apply these coatings is with a specialized tennis court application squeegee.  Using a paint roller on a hot day, in the full sun, on coatings that hold up to 15 pounds of sand per gallon can make a real mess.  Plus, if you’ve never applied coatings with a squeegee, you are in for a not-so-good surprise.  Especially, if you are attempting to paint a two-color court.  Experienced tennis court resurfacing contractors may paint anywhere from 50 to 400 tennis courts in a season.  They have plenty of practice and have the skills to squeegee two different colors that are only separated by a 2″ line, without going over into the other color area.  Not to mention, multiple coats within the same day.

Over the years, many do-it-yourselfers have attempted to paint their own courts with a variety of results.  The vast majority will never do it again and even needed to hire a professional surfacing company to fix their attempt.  Here is just a short list of reasons why it is cheaper and easier to have an experienced tennis court contractor paint or resurface your tennis, basketball, or sports court:

  • Tennis court contractors buy concentrated coatings in large volumes and have better pricing on materials than DIY.
  • Sport contractors have all of the necessary tools and experience to do the job right and quickly.
  • Court contractors also have a specialized line taping machine for layout of straight and curved lines, prior to striping.
  • Most sport contractors have a variety of methods and systems for crack repair, including installation of patented membrane repair systems which require factory training.
  • Construction alternatives: If standard acrylic repair materials cannot address the repairs, tennis court construction companies can offer more permanent repair or reconstruction.

If it is time to paint or resurface your tennis, basketball, or pickleball court and you are looking for a qualified sport surfacing contractor, contact us.  We can put you in touch with experienced installers that can provide free estimates on a professional and affordable court repair, resurfacing, or construction project.

How Often Should Tennis Courts Be Resurfaced?

Tennis courts should be resurfaced every 4 to 8 years.  This is a standard range with quite a few variables, as you could imagine. Lets go over some reasons why the same resurfacing process would last 4 years on one court and 8, or double the amount of time, on another.

Tennis Court Construction Methods | Surface Longevity

Tennis courts, and other sport surfaces, should be properly built. There are important differences between a parking lot or driveway, and a tennis court surface.  The American Sports Builders Association (ASBA) maintains construction guidelines for tennis courts and even has a certified tennis court builder program.  If tennis courts are not built correctly, they could require more frequent repairs and resurfacing.  Here are just some of the common construction problems influencing the decision of how often tennis courts should be resurfaced:

  • Improper slope = ponding water and premature breakdown of acrylic surfacing system.
  • Insufficient compaction  = susceptible to deforming, moisture damage, cracking, etc.
  • Incorrect or missing drainage system = backup of water and a long list of problems like surface bubbles/blisters, premature surface wear, and more.

Environmental Conditions and Surrounding Issues | Resurfacing Cycle

Acrylic tennis court surfaces require very little maintenance, but here are few important tips in extending the life of color coatings:

  • Surface debris removal – Don’t let leaves, pine needles, or any other organic debris build up on the court surface.  It will hold moisture and rot on the surface.  This is cause faster wear of the tennis court surfaces.
  • Trim edges – Be sure to keep grass, vegetation, and dirt trimmed down around the court edges.  This will help to prevent back-up of water that drains off of the court.  Puddled water will break down the acrylic surface coatings prematurely, and result the need for more frequent resurfacing.
  • Periodic washing –  Light to moderate pressure washing of the surface with mild detergents will help to extend the surface life and keep the court surface looking good.

Acrylic Resurfacer | Money Well Spent When Resurfacing

Many court owners want to skip the Acrylic Resurfacer step and just apply the color coatings.  Acrylic Resurfacer re-textures an old smooth court and helps to ensure the proper application rate of color coatings.  Since tennis court coatings are applied with a soft rubber squeegee, the colored surface coatings tend to “wipe off” when the surface is old, smooth and polished.  This results in thinner surface layers that won’t last as long, and definitely impacts how often the tennis court should be resurfaced.

Active Players and Busy Tennis Courts

Obviously, if there is good tennis programming and lots of players, it can impact the wear of the tennis court surfaces.  Active players and high traffic counts will speed up wear of the surfaces.  If this is known before resurfacing, talk to  a SportMaster representative and they can offer recommendations or prepare a custom scope tailored to your facility.  Extra coats may be recommended to extend the life of your tennis court surfaces.

Can Pickleball Be Played On A Tennis Court?

Pickleball has become one of the fastest growing sports in the nation.  The demand for places to play Pickleball leads to the question, “Can Pickleball be played on a tennis court?”  

Yes, Pickleball can be played on a tennis court surface, and we will discuss some great options to keep Tennis and Pickleball players happy.

Blended Pickleball Lines On A Tennis Court

A common trend, that is working well, is to maximize the current “real estate” of existing tennis courts.  That is usually a “win-win” and has been done for years with tennis and basketball court combinations.  By USTA and ITF rules, tennis court lines must be white.  Pickleball court lines can be added in a different color, so that tennis or pickleball can be played on the same court (at different times, of course) and the eye can focus on the applicable set of playing lines.  As with the USTA’s kids tennis program known as 10 & under tennis or Quickstart, it is usually recommended to paint the Pickleball lines in the same color family as the court surface color. To better explain, if the court color is blue, apply the Pickleball lines in a shade of blue that is lighter or darker than the surface color. This makes the lines less distractive to tennis players.

How Much Does It Cost To Add Pickleball Lines To A Tennis Court?

This is a relatively inexpensive process and is usually performed by a qualified tennis court contractor.  It can range anywhere from $250  to $600 per court, depending on a variety of factors:

  • Existing surface condition (how much cleaning and prep is needed in order to get the new line paint to adhere properly)
  • Total number of Pickleball courts to be painted (better price per court, for multiple applications to minimize mobilization)
  • Lower cost to apply the Pickleball lines as the tennis courts are being resurfaced.

To get a free estimate from a qualified Pickleball court contractor on your facility, contact us and we can put you in touch with an experienced installer.

Pickleball Court Construction | Permanent Pickleball Courts

There is also a boom of permanent Pickleball courts being installed in park districts and residential settings.  Since Pickleball courts are smaller (44′ x 20′) than tennis courts (60′ x 120′), more and more avid players are building backyard Pickleball courts.  It is great fun for families, kids, and older players alike.  In fact, many older players that are unable to physically handle tennis are turning to Pickleball for fun and fitness.

Pickleball court construction utilizes the same construction methods as tennis and basketball courts.  Generally they are comprised of an asphalt or concrete substrate, and then surfaced with a non-slip, textured SportMaster brand of acrylic surface.  Here are some additional resources for Pickleball court construction, surfacing, and striping layout:

How Do You Get Rid Of Puddles On A Tennis Court?

So, how do you get rid of puddles on a tennis court?  Puddles on a tennis court are a nuisance for many reasons.  Either you wait for the water to evaporate before you play, or get a court dryer to move the puddles off the surface.  Puddled areas, or low spots, can also be a trip hazard if they have sunk enough to effect the players footing.

But what about adverse effects on the acrylic surfacing?  Acrylic tennis court surfaces are very durable, and designed to have good wet adhesion and resistance to the elements.  However, if water sits on the surface for prolonged periods of time, it will shorten the coating life and begin to break it down.  Plus, when water puddles in those areas, dirt and debris tends to accumulate in the water.  This creates a sandpaper-like friction on the surface from play and scuffing of tennis shoes.  The bottom line is, none of this is good for the tennis court surface.

Removing Low Spots and Puddles with Acrylic Patch Binder

The American Sports Builders Association maintains guidelines for puddles, or “birdbaths” on a tennis court surface.  A hour after a rain, or flooding the court, any area where standing water is measured at 1/16″ (2mm) is in need of patching.  This is usually measure by placing a U.S. nickel in the center of the puddle, and if the water covers the head of the nickel, it is deep enough to require leveling.

Acrylic Patch Binder is a 100% acrylic binder that is job-mixed with portland cement and specifically graded silica sand.  This creates a slurry that can be poured into the puddle area and screeded in with a steel or aluminum straightedge.  If done properly, this will bring the low, puddled area back to level and allow the water to flow off the court (with help from the court’s 1% slope).

Is Tennis Court Patching a DIY Project?

Leveling birdbaths and patching tennis courts can be very tricky without proper experience.  If not properly done, you can easily create a dam on your tennis court surface.  We would highly recommend seeking a qualified tennis court contractor to do this the correct way.  Feel free to contact us and we will be happy to provide you with experienced and affordable sport surfacing professionals.

What causes bubbles or blisters on a tennis court surface?

Bubbles and blisters on a tennis court surface, or other coated sport surface, are fairly common.  This is usually a result of improper tennis court construction or malfunction of the drainage system. When sub-surface water becomes excessive and is not properly drained away from the court, it can breathe through the slab in a vapor form and create hydrostatic pressure under the coatings.  This pressure builds more in weaker surface areas and creates a blister or bubble.  When the blister is raised, water vapor stretches the coating film and slowly breathes through to escape.  After most of the water pushes through, blisters usually lay back down and disappear until the next rain or precipitation event.  It’s important to note that excessive watering (sprinklers) around the court edge can also lead to blistering problems.  That being said, it’s very important to minimize accumulation of water beneath the court slab.

How Do I Get Rid of Bubbles and Blisters on a Tennis Court Surface?

In order to take care of the bubbles and blisters, long term, you will need to do some investigating.  Start by making sure any and all drains around the tennis court are free of debris or anything that would prevent proper flow of drainage water.  You may want to enlist the help of an architect or excavation professional in order to evaluate the current drainage system and see if it was installed properly, or at all.  If the court substrate is concrete, you must ensure the following:

  • Was a vapor barrier installed beneath the court when poured?
  • Are there perimeter drains that can take the water away from the court when it runs off after a rain? (Important that water is intercepted on all side of the slab, to prevent water beneath the court)
  • Was the concrete allowed to cure for 28 days, prior to coating?
  • Was the concrete surface acid etched to neutralize the alkalinity and balance the PH?
  • Were any curing compounds used on the concrete?

The American Sports Builders Association (ASBA) maintains construction guidelines for asphalt and concrete tennis court and sport surfaces.  Ensure that the construction of the court meets their guidelines and find out from the tennis court builder if they followed the ASBA recommendations.  This may help you figure out why the blisters are occurring.  If you are still not sure what to do, feel free to fill out the contact form on this page and we can put you in touch with a SportMaster recommended, tennis court builder.  They can perform a free site visit with you and provide feedback and estimates for repair, resurfacing, or re-construction.

What Causes Rust Spots On A Tennis Court Surface?

In various regions, rust spots are a common sight on tennis court surfaces.  They are actually visible on driveways, parking lots, and other asphalt surfaces, but they are more pronounced on a colored tennis court surface.

The rust spots are the result of metallic minerals, called pyrites, that contaminate the stone used to create asphalt.  Asphalt pavement and acrylic tennis surfaces allow vapor to transmit, or breathe through them.  When the mineral pyrites become wet, they rust and bring the stains upward into the acrylic surfaces.  These rust stains are unsightly and mostly an aesthetic issue that don’t affect the ball bounce or play of the game.  However, sometimes the aggregate reacts, swells, and pops out.  This leaves a rust stain and sometime a small mound with a tiny hole in the surface.

Unfortunately, there isn’t a good or compatible primer or stain blocker that can prevent this from happening.  The best defense is a good offense, which means:

  • Use only non-recycled asphalt when paving tennis and basketball courts
  • Do research: Stay away from limestone or aggregate sources with known contamination issues
  • Talk to an experienced architect and/or tennis court contractor ahead of time in order to avoid the wrong asphalt type and source.

If it is too late and you already have rust spots on your tennis court, here are a few tips:

  • Your tennis court contractor can use a hand drill and drill out the reactive spots.  Acrylic Crack Patch can be used to repair the surface holes and the court can be touched up or completely resurfaced.  Sometimes there are hundreds of rust spots and drilling is not always a viable option.
  • This may sound silly at first, but you can pick a color scheme that closely matches and doesn’t contrast the rust color (i.e., Brown, Maroon, Red)

Kids Tennis | Adding Blended Lines for 10 and Under Tennis

The QuickStart (10 and under) tennis format, also known as Kids Tennis, is a program that the USTA is promoting to ensure the growth of tennis.  Statistics show when kids learn a sport early in their lives, they are more likely to continue playing throughout their adult life.  Kids tennis takes it one step further and reshapes the tennis court surface dimensions, racquet sizes, and tennis balls to better fit the size and abilities of kids.  This makes is much easier for kids to begin learning their tennis techniques, and have fun doing it!

QuickStart/Kids Tennis has changed the following standards, to meet the needs of kids:

  • Smaller Tennis Courts – Less area for kids to cover
  • Specialized tennis balls with less compression for slower and lower bounce
  • Smaller kid-friendly racquets for easier handling
  • Modified scoring rules for age groups

Many clubs, parks, and schools have begun adding kids courts to their facilities.  Some have installed permanent quickstart courts, but many have been adding blended lines so that players of all ages can use all of the courts.  This makes the best use of space, and provides flexibility at a minimal cost.  Blended lines for kids tennis, are normally painted with a shade of line paint that is lighter or darker, but of the same family as the tennis court surface.  For example, if the inside court color is blue, the quickstart lines must be a darker or lighter shade of blue.  The standard court lines are always white.

There are two different sizes, when it comes to quickstart courts.  The 60 foot court length is for 9 and 10 year olds, and the 36 foot courts are for ages 8 and under.  If you have a court that is designated for kids, you may also check with a surfacing manufacturer or contractor about resurfacing your court with a slower playing acrylic surface.  This will slow the ball bounce down and give the kids more time to get to the ball and volley.

If you are interested in finding a qualified tennis court builder near you, fill out the contact form on this page and we will provide qualified contacts.  We can recommend authorized installers near you that are trained in application and knowledgeable in standard tennis and quickstart tennis court layout.

 

Silica Sand for Coatings

How Important Is Silica Sand In Tennis Court Paint and Coatings?

Using the correct size and shape of silica sand is very important to each specific coating or repair product used in tennis court resurfacing.  The right kind of sand is integral to the performance of each tennis court coating, patch material, or crack filler.  Without the proper sand type and amount, a coat cannot achieve its purpose.

Tennis Court Coating Coverage Rates

Tennis court coatings are squeegee applied.  The squeegee floats at the highest point of a coating, so if you are using a larger silica sand, the squeegee rides higher.  This will generally yield a thicker coat and use more coating, unless there are lots of asphalt voids and the sand it pushed down into them.  If a finer sand is used, as in the color coats, you will use a little less material and put a thinner coat.

Silica Sand for Acrylic Resurfacer and Acrylic Patch Binder (50-60 Mesh)

The size and shape of silica sands both have a specific purpose.  The lower the number, the larger the particle size (in the AFS scale of measurement).  Since Acrylic Resurfacer and Acrylic Patch Binder are both filling voids in asphalt and concrete, the larger mesh size is better.  Also the angular shape allows the sand to key together and form a nice, strong base film or patch.  Acrylic Resurfacer is also designed to provide a consistent, but somewhat rough surface.  This helps the color coating grab on and apply at the correct thickness for good coverage and long wear.

Silica Sand for Tennis Court Color Coatings and Line Paint (Rounded 80-100 Mesh)

The silica sand that is commonly used in color coatings is finer and mostly rounded.  The rounded shape helps the sand to roll under the squeegee, instead of dragging through like a small stone that fell into the puddle.  This helps to minimize surface streaking and provide a smoother, blemish-free surface.  The smoother finish also reduces the amount of tennis ball fuzz, which creates more housekeeping issues in indoor tennis clubs and facilities.

SportMaster tennis court coatings are manufactured with fibers, which will also minimize tools marks and streaks in the color coatings. The use of fibers is a big help, since many court owners and players are looking to slow down the play by using larger and more angular-shaped silica sands in the colored tennis court surface coatings. The fiber-containing formula of SportMaster enables them to have the surface speed they want, with less streaking than most other brands.

Indoor Tennis Court Resurfacing Problems | Common Drying Issues

Resurfacing indoor tennis and recreational courts can have a few challenges not common to outdoor tennis court resurfacing.  Indoor tennis courts do not have to contend with outdoor enemies like UV rays and harsh weather, but some indoor conditions can wreak havoc, even for the experienced tennis court surfacing contractor.

This article is relevant to all kinds of indoor acrylic courts, including by not limited to:

Indoor Tennis Court Resurfacing | Drying Problems

Acrylic tennis court surfaces are water-based and dry by evaporation.  Water is the vehicle that allows the heavy coating solids to be squeegee applied.  Once the coating is applied, the water begins to evaporate.  If there is not adequate ventilation in the facility, the water can be trapped in the airspace above the courts and slow down the drying of the surfaces.  This can cause a “marbled” look on the coating, resulting in light and dark or patchy areas.

Marbled Tennis Court Surface
Marbled Tennis Court Surface

Poor ventilation and cooler outside temperatures can also create problems by causing condensation to “rain” down onto the tennis court surfaces.  If the inside temperatures are warmer and the ceiling is cool from colder outside temperatures, the moisture can drip onto the partially cured surface, creating blemishes.  To prevent both of these issues, make sure to turn on heating or air conditioning systems to draw humidity out of the air. Open any available vents, doors, and windows to allow an escape route for moisture.  Large industrial fans can also be rented and help to circulate the air, as well as push moisture out when placed at exterior doors.

Indoor Tennis Court Drying Problems

If the facility doesn’t have a good way to expel the moist, humid air, you may need to bring in industrial dehumidifiers.  Until the high level of humidity is allowed to escape, the coatings will not be able to dry and cure.  They will retain the marbled or uneven drying pattern, and be susceptible to damage and early wear.  Plus, when the coatings are like this, it will be very difficult to get tape to stick to the surface for painting the playing lines.

Loose Sand On Indoor Courts | Drying & Curing

It is also common to see loose silica sand on an indoor athletic facility, and sometimes on outdoor courts.  Court coatings are fortified with silica sand in order to provide a non-slip surface and ideal ball trajectory for speed of play.  The latex binders in acrylic coatings need to dry completely before they can cure.  Once the full cure is complete, the coatings can coalesce or fully cure.  When the full cure happens, the components (sand in this case) of the coating are full bound and locked in to the coating film.  In some cases, this can also have the same affect on pigments.  If tennis balls become a bit colored from the surface, it is also a drying/curing issue.

The large amount of evaporating water, from the coatings, can take a while to escape from inside the building.  This depends on the ventilation, and more importantly, the exhaust system of the facility.  When the indoor humidity level is high, it slows down the cure of the coatings.  The silica sand can be rolled out of the coatings and or can migrate out if very humid.  There is no need to worry about this, as it will slow down and stop as the full cure is reached.

The quicker you can get the interior humidity level lowered, the sooner the sand roll-out will cease.  Here are a few things that can help:

  • Rent big agricultural fans and point them outside, by an open doorway to exhaust interior humid air.
  • Turn up the heater and run all fans to keep air moving, with the main focus on exhausting the moist air at the same time.
  • Air conditioning takes moisture out of the air.  Just keep a balance of using AC and heat, since heat helps the curing process more than cool conditions
  • Industrial dehumidifiers can also be used to bring inside humidity levels down.  Check with local equipment rental stores to find ones for rent.
  • Also ensure that the slab/ground temperature and air temperature is well above 50 degrees F.  Warmer is much better, but acrylic binders cannot cure when the temperatures are below 50 degree Fahrenheit / 10 Celsius.

Tennis Court Squeegee Application Issues | Smooth Indoor Court Surfaces

Another common problem with surfacing indoor tennis courts is application of coatings on a very smooth surface.  Indoor courts do not benefit from the wind and rains, which actually help to move debris off the surface.  Dirt and sand particles, that come out of the surface, become abrasive to color coatings under the scuffing of tennis courts.  Long-term, this can create a very smooth surface which makes it difficult for application of color coatings.  The application squeegee can wipe the coatings off of a smooth surface, and leave a very thin coating.  This can sometimes cause irregular color patches or inconsistent textures on the surface.  To prevent this, apply the first coat of Acrylic Resurfacer (properly mixed with sand and water) with a squeegee, but follow directly behind with a soft, horse hair-type broom or brush.  This puts a fine grooved text in the coating.  Once the first coat of Resurfacer is dry, squeegee apply another coat of resurfacer, going the cross-direction.  This allows the second coat of resurfacer to “grab” onto the groove finish and deposit a complete textured coat.  At this point, the surface is ready to accept the tennis court color coating surface layers.

 

Tennis Court Crack Filler

How Long Does Tennis Court Crack Filler Last?

Question: How long does tennis court crack filler last?

Answer: Cracking of asphalt and concrete pavement surfaces is a common problem. Even if the asphalt or concrete is properly built, there are still variables beyond the control of the contractor and crack filler producer.

There are different reasons for pavement cracking, but a majority of the cracks on concrete and asphalt courts are structural. This means that the cracks go completely through the pavement layers, into the base of the tennis court.

Acrylic tennis court crack fillers are designed to fill and seal off the surface of the crack. This is designed to minimize water and moisture flowing into the crack and stone base of the court, and slow down degradation of the court through further cracking. The main problem is that once a structural crack opens, there are two separated slabs of pavement constantly moving back and forth. This expansion and contraction happens daily, depending on temperatures, moisture, and other environmental conditions. That being said, cracks that have been filled may open within days, weeks, months, or years of application. An Acrylic crack patch is an ideal solution for this common problem.

Even though we offer some elastomeric acrylic crack fillers, the degree of movement in the crack determines how long the product can perform before breaking open or pulling away from one side of the crack. Frequency of moisture, freeze-thaw, and various climate conditions are other factors that play a role in longevity of crack fillers and repair.

Crack filling is a maintenance role. The best way to maintain a tennis court crack is to fill it whenever you see it open. A good rule of thumb is to check the court(s) over in the spring and early fall (when temperatures are not getting below 50°F or 10°C) and perform necessary crack filling to extend the life of the facility. Many sport surfacing contractors also offer maintenance programs, where they make spring and fall visits annually, and advise court owners of needed crack repairs, resurfacing, or other issues.
