Concrete Sealer Removal on Outdoor Pavers in Kendall

Case Study | Kendall

Concrete sealer removal on outdoor pavers at a Kendall home: about 1,500 square feet of concrete slabs set in turf. The pavers had been sealed more than once, with different products, and the layers never bonded. This is part of our concrete restoration work. Here is what we found, what we did, and how it was finished.

STEP 1 OF 3

The pavers had been sealed with a combination of different sealers, one on top of another. Different products do not always bond to the concrete or to each other, and these never did. Rolling one more coat over them would only have added another layer with nothing solid to hold onto. The old sealers had to come off first.

STEP 2 OF 3

We did a sample area first, so the owner could see the result on their own concrete before we did the whole job. Then every paver was ground with metal diamonds on a planetary floor grinder with a dust shroud and vacuum, with a hand grinder along the edges. Metal diamonds only. The goal was to take the old sealers off and open the pores of the concrete so a new sealer could soak in and bond.

STEP 3 OF 3

With the old sealers gone and the pores open, we rolled on StoneTech BulletProof, a water-based penetrating sealer, slab by slab, and let it dry. A penetrating sealer soaks into the concrete instead of sitting on top as a film, and because it went onto bare, open concrete instead of over old layers, it has something to bond to.
