Be aware of cheap imitations!
Recently we have noticed at least one company selling a tennis court paint that looks like a decent price until you read further. Sometimes you see the word “Smooth” appearing in the description, or you may find “slip-resistance” is not mentioned anywhere in the ad. This may mean it has no added sand. Coating without sand will stretch farther than coating with sand, because it is a much thinner product. However sand is an integral component of a quality sport coating as it prevents the players from slipping when the court is damp, and the tennis ball from skidding as it strikes the court.
ASK IF THE PAINT CONFORMS TO THE LAWN TENNIS ASSOCIATION REGULATIONS FOR SLIP-RESISTANCE, OR HAS ADDED SAND TO GIVE IT TEXTURE.
A paint without added sand may feel OK underfoot when the court is bone-dry, but a hint of damp or dew will be likely to render the court unplayable (not very useful in the Great British climate!). Often, if asked about slip-resistance, the seller will tell you to drill in some kiln-dried playpit sand from your local DIY store – this is time-consuming, creates additional cost, it may result in uneven texture, and this mix will not pass through an airless sprayer as a fine mist. Buyer Beware!!! If it sounds too good to be true, it almost always is.
