Tennis Court Surfacing: How To Prep and Patch Your Court

Oh, the joys and woes of owning your own tennis court!  

You get to have volleys with friends and hit shots that leave their mark (sometimes literally). All that fun, laughter, and sometimes, bickering – the home court sees it all. But while little dents and faded tennis court lines may add character, major cracks, holes, and other repairs can render your court unplayable. 

Have no fear – with the right prep and materials, you can patch things up in no time.  

 In this post, we’ll walk through simple steps for tackling common court repairs and tennis court surfacing so you can keep the good times rolling all season. Grab your tea, and let’s talk fixes that’ll have you yelling, “Game, set, match!” in no time.

How to Do Repairs for Cracks Less Than 1/2 -Inch Wide

Before anything else, you'll want to gather your tools and materials. For small cracks, you’ll need a crack filler, sand or a backer rod, and elastomeric caulk that matches your tennis court’s surface. Start by giving your court a good sweep. Clear away any debris, leaves, or dirt from the cracks. This step is crucial as it ensures the filler adheres properly. 

The next step is to fill them. If the cracks are deep, use sand or a backer rod to fill them up to about half an inch below the surface. Next, apply the elastomeric caulk. This type of caulk is flexible, which is crucial as it allows for expansion and contraction due to temperature changes without causing further cracking.

How to Repair Large Cracks 

Large cracks, which are more than ½ inch wide and over 40 feet apart, require more elbow grease. Just like with smaller cracks, start by thoroughly cleaning the area. Remove debris, weeds, or dirt from the cracks to ensure a smooth repair process. 

For these larger fissures, a simple caulk won’t do the trick. You’ll need a flexible membrane repair kit. First, fill the cracks with sand or a backer rod, just as you did with the smaller ones.  Then, install the flexible membrane. This is a multi-layer system that bridges the gap over the crack. It's designed to move with the ground and reduce the likelihood of the crack reappearing. 

The membrane also prevents water from seeping into the repaired area, which is crucial for long-term maintenance. 

 Once the membrane is in place, a new layer of acrylic surfacing will be necessary. This not only covers the repair but also gives your court a fresh, uniform look.

When to Call In Court Repair Pros

Extensive cracks, significant asphalt damage, or a full-court rebuild? It's time to hire court repair professionals.

With hands-on effort and quality materials, you can make your home court like new. Don’t let minor cracks bar you from enjoying tennis with friends and family. As long as the court’s foundation remains intact, patching is within reach! 

Now grab a racquet and celebratory lemonade - you’ve earned a winning match on your revived court.
