Summertime. There was never a better time to highlight this Double Oak, TX concrete pool deck with an acid stain, scoring, and sealing. Whenever we do an acid stain, we always place color samples for our customer's approval prior to staining, but our homeowner could not decide which one she liked best: the umber or the black acid. We gave her both! We swirled the two acids together, using separate sprayers to apply them. Mixing the two stains creates a new composite color while "bands" of the original colors are still visible. Do you like the look of this concrete pool deck?
The beautiful acid stain colors are always enhanced with a nice scored pattern. These were 24" tiles cut using a diamond saw blade. We usually mount this blade into a shrouded circular saw that helps trap dust in the cutting process. The shroud covers around 90% of the blade and has an attachment for a hose from a shop vac. We use the saw for the majority of our long cuts then come back with a handheld grinder with a smaller diamond blade for touchups: one guy cutting and the other holding a vacuum cleaner hose right next to it.
We always do touchups because no floor is perfectly flat, and this concrete pool deck was certainly not the exception. The big saw's height can't be changed on the fly, so we need to do manual touchups. Sure, we could just make deeper cuts with the big saw, but as any homeowner with tile knows, deep grooves in the floor accumulate dirt. We avoid this by making light, shallow cuts (no more than 1/8" on average) and wherever the concrete dips, we come back with the handheld grinder to level it off. A big advantage diamond blades have is that they make smooth cuts and last very long compared to abrasive style blades. To wrap things up we sprayed a solvent-based concrete sealer over the entire pool deck, making the acid stain colors "pop." Our next project didn't have any fancy scoring but did take into account the importance of choosing colors and making samples.
