Yes. A newer slab is usually in better condition, but the surface of fresh concrete is closed and a coating will not bond into it as it is.

Grinding opens the surface so the system anchors into the slab rather than sitting on top of it.

Usually yes. Age by itself is not the problem — moisture coming up through the slab is, and a lot of older houses here were built without a barrier underneath.

We check the slab before quoting. If the reading is high we put a barrier down first; if it is clean, nothing extra is needed.

No, it comes up constantly and we plan for it. With the garage door open the floor counts as something the neighbors see, so the board usually wants to sign off on the color first.

We bring physical samples you can submit and schedule the install once you have approval, so the floor is never done twice.

Not a problem, but it does change what we put down. Salt in the air is hard on a coating, and the first place it shows is around the edges and the door line rather than in the middle of the floor.

Close to the water we use a topcoat made for that exposure and seal the edges properly instead of running the coating to the wall and calling it done.

You can walk on it the next day. Vehicles need longer, because tires put far more stress on a fresh coating than feet do.

We give you the exact window before we start, so you can plan where the car goes in the meantime.

Yes, the floor has to be completely clear before we start — including shelving and anything fixed along the walls.

If moving heavy items is a problem, tell us when we quote and we will build it into the plan rather than leaving it to the morning of the job.

Almost always one of two things. Either the slab was never tested for moisture and vapor lifted the coating from below, or the preparation was acid etching rather than mechanical grinding, so the coating never had a proper mechanical bond.

Both are preparation failures, not product failures — which is why replacing the coating without addressing the cause produces the same result again.

A UV-stable topcoat is used to protect the decorative layer against sun exposure, helping maintain color consistency over time.
