We have 1000 square foot of concrete deck that was installed this past summer when we had our pool built. We live in South Carolina and heat is legit. We have two quotes, 1 is for $4 a square foot for Spraydeck using SGM products. The company was suggested by our Pool Builder and has very good reviews. The second quote is another well reviewed company who quoted $5 a square foot to install Kooldeck. Is it worth $1000 extra dollars for Kooldeck? The finish of both looks very similar.
