Concrete Sealers

Sealers are applied to concrete surfaces to protect them from the elements and extend their useful lifespans. There are two main types of sealers: film-forming varieties that enhance the surface with color and sheen, and penetrating sealers that go into the concrete’s pores and seemingly disappear.

Question: I have a 5-year-old stamped concrete patio that has not been resealed since being installed. The sealer is cloudy in some areas and in other areas looks like there is no sealer at all.

My contractor placed blue painter’s tape on the concrete for a few days to mark the placement of cabinetry. The tape was removed and the concrete was sealed with two coats of 25 percent solids acrylic sealer and two coats of acrylic finish. A few days later the concrete was discolored and had evidence of where the tape had been placed. No surface damage to the concrete was evident.

Use of Penetrating Sealers on Concrete is on the Rise

The decorative industry grew up on the “one size fits all” high-gloss sealer which was the go-to coating for decades. While high gloss is still widely used, low-gloss and natural finishes in the decorative concrete industry have been gaining momentum as homeowners, architects and designers seek more ecofriendly, green and natural-looking sealing options.
