Consider spraying followed back rolling when sealing stamped or textured surfaces with a solvent-based sealer. … Push and pull the sealer around, maintaining a wet edge.

Can you stain concrete after it’s been sealed?

Acid staining concrete produces rich, deep, translucent tones unlike paints or coatings that produce a solid, opaque effect. If the concrete surface is painted or sealed, acid stains cannot penetrate the concrete and react with the lime. Therefore, a concrete surface that is painted or sealed cannot be acid stained.

Why is my stained concrete turning white?

Efflorescence is a white salty residue caused when too much moisture is moving through the concrete. As the concrete dries and its moisture rises upwards through the slab, it brings salts within the concrete to the surface as well. As lovely as the word sounds, efflorescence is rather unsightly.

Does concrete sealer wear off?

How long will my sealer last? Because they penetrate the concrete, reactive chemical sealers will last the longest and generally only wear away if the substrate surface itself wears away, which may be 10 years or longer.
