If your patio has been out there since the house was built, you have probably wondered whether it is too far gone to be worth doing anything with. Most of the time it is not, and a coating gives you back a clean, even surface you can use instead of a slab you work around. Older exterior concrete is what we are asked to look at most in Tempe, and whether it will take a finish comes down to its condition rather than its age. Dialed In Epoxy seals these in UV stable polyaspartic once the slab has been ground back to something solid. ROC 358358, and we are licensed, bonded and insured.
Call (602) 820-7739Three things decide it, and you can check two of them yourself before we arrive. Look at whether the surface is still sound underfoot or whether it powders when you scuff it, because concrete that sheds material has lost its top layer and needs taking back to something a finish can hold onto. Look at where water sits an hour after you hose it down, since standing water is the failure no topcoat fixes and it has to be dealt with before anything goes over it. The third one is ours: we check what is already on the slab, because old sealers and patio paint have to come off first, and a property of any age tends to carry several layers of them.
The thing people expect to rule it out is cracking, and it is usually the least of it. Cracks, spalled edges and pitted areas are cut back to sound concrete, filled and ground flush during preparation, so they stop being the thing your eye goes to every time you walk past. Control joints stay as joints, honored rather than filled over, because they are what lets the slab move without tearing the finish above it. What you end up with is easier to keep than the concrete you have now, and you stop losing the space to how it looks. There is more on what the preparation stage actually removes on our Phoenix page.


Sometimes it is, and you should hear that from us at the quote rather than find it out afterwards. If the concrete has broken into sections that move independently of each other, or if moisture is arriving from below the slab rather than landing on top of it, a coating will not hold and we will tell you so. That covers a small share of what we are asked to look at. The rest are in better shape than their owners assume, because most of what makes old concrete look past it sits on the surface and comes off with the grind.

Three stages on every exterior concrete coating in Tempe, AZ, and the first one decides the other two.
We mechanically grind, profile and vacuum the concrete with diamond tooling, which takes off the weathered top layer along with any old sealer. Exterior slabs almost always carry one, and a coating laid over an existing sealer has nothing to bond to. That preparation runs under every interior floor we lay: the four layers of an epoxy floor build, in order.
Cracks, spalled edges and pitted areas are cut out, filled and ground flush. Control joints are honored rather than filled over, so the slab can still move where it was designed to move instead of cracking somewhere new.
Then the system itself: a polyaspartic base, the color layer, and two coats of UV stable polyaspartic over the top, with anti-slip aggregate broadcast in where it was specified. A polyaspartic build goes down in a day, which on a driveway is the difference between one afternoon without the car and a week of it.
