For concrete deck material is Kool Deck or an acrylic considered superior?

Answer 1

As with all design choices, the answer is it depends on what you are trying to achieve. First, let's start with a few basics on understanding the comparison. A genuine Kool Deck brand surface from Mortex Mfg. is a pure cementitious topping unlike an "acrylic", which is a polymer modified cement. A Kool Deck surface will undoubtedly have a lower relative surface temperature than an equivalent acrylic topping of the similar color and will also be more skid-resistant when either wet or dry. A polymer modified cement topping will generally have much better stain resistance than a Kool Deck surface (which can be enhanced to provide similar stain resistance at a cost). Polymer toppings for the most part are deemed easier to apply and require less people for a job. This simplicity does come at a price, as the cost of materials is significantly higher than all the materials required for a Kool Deck surface. The major hurdle for those looking for Kool Deck surface is finding a skilled applicator to insure a proper application - look at the work of the contractor and do your homework!

Bottom line is that a Kool Deck surface is still the best choice for barefoot areas where comfort is king, while polymers are better suited for deck areas expecting staining problems, customer wants custom patterns, or applicators are more comfortable installing the latter.

Sun Deck is an acrylic concrete deck finish that is very durable, stain resistant, and cool. Also quite popular in South Texas.
