SOMAY Sports Court Coating vs. Acrylic Latex Floor Enamel
SOMAY Product No. 942, SOMAY Sports Court Coating can be applied to many different kinds of court surfaces, including very firm, hard, well-cured asphalt pavement. Once cured, it can withstand pedestrian traffic in tennis shoes.
Please note that you should never apply a very hard coating over a relatively soft surface, such as an
asphalt pavement, because it could result in cracking or delamination of the coating. Epoxy and urethane coatings are generally very hard, thus they work on a very hard substrate, like concrete, which does not flex
in any way. A hard epoxy coating applied to a soft substrate (such as soft asphalt pavement) may have a different modulus of flex, which can result in separation from the substrate, resulting in coating failure. A
coating that is flexible enough to move with a soft asphalt surface may not be hard enough to withstand roller blade skating on its surface. We are not aware of any consumer quality waterborne paint that we would be
confident to recommend for use on roller blade skating areas. We believe areas subject to hard play with hard wheels should be very firm surfaces (like concrete) that can be coated with a 100% Solids by Volume,
2-component epoxy floor coating or 2-component acrylic/polyester/polyurethane coating. Normally these coatings will be very hard when cured, so could withstand roller blade wheel traffic, but they must be applied over a very
hard substrate. They also would be quite slick and slippery, so you normally would add a non-skid additive into the coating before application, or broadcast on top of the first coat as you apply the coating, while it is still
wet, prior to it having time to set up and cure. For longer-term durability, it is wise to sandwich the non-skid between the first coat and a subsequent thin overcoat or topcoat. While a "white" color will
reflect the most heat and be the coolest to skate or play on, most folks are concerned that it will be too bright and blinding, so they normally want a light "gray", light "tan" or "Tennis Court Green" color.
SOMAY Product No. 230, SOMAY 100% Acrylic Latex Satin Finish Floor Enamel contains a very fine anti-skid additive. SOMAY Product No. 942, SOMAY Sports Court Coating, also a 100% Acrylic Latex Coating, contains a coarse
anti-skid additive. Product No. 230 will have a material cost of approx. 4-5¢/sq.ft. per one mil (1/1000th
inch) dry film thickness (DFT); or 20-25¢/sq.ft. at 5 mils DFT; 32-40¢/sq.ft. at 8 mils DFT, etc. The material cost always depends on the smoothness vs. roughness, the density vs. porosity of the surface, and the thickness at which you apply the coating to the surface.
Product No. 942 will have a material cost of approx. 2-3¢/sq.ft. per one mil (1/1000th inch) dry film thickness (DFT); or 10-15¢/sq.ft. at 5 mils DFT; 16-24¢/sq.ft. at 8 mils DFT.
