ExposedExposed Aggregate Concrete Sealers

Concrete that has had the outer skin of the cement paste removed to reveal the decorative surface underneath is called exposed aggregate concrete. It is very durable and skid resistant. It can be ideal for driveways, sidewalks, patios, pool decks, and patios.

Sealing aggregate concrete will further enhance its beauty and help protect it from the harsh elements and deicing salts. An exposed aggregate sealer will also reduce mold and mildew problems, stabilize the surface, protect color retention, and protect against freeze/thaw damage.

An exposed aggregate sealer can be easily applied with excellent results by any homeowner. Failure to maintain an aggregate surface can result in a color loss, pitting, cracking, and leave the surface exposed to stains from spills.

Cleaning and prepping the aggregate surface prior to sealing it is vital to the performance of the new sealer. Pressure wash the surface to remove dirt, mold, mildew, and grime. If necessary use a concrete cleaner to assist in removing stubborn stains. Use a degreaser on oil spots and rust remover on irrigation rust stains if necessary.

After cleaning the exposed aggregate allow the surface to dry for 2 days before sealing. The best exposed aggregate sealer is a solvent based acrylic sealer. Use a ½” nap roller and coat one section of concrete at a time. If the concrete is broken up into squares due to the saw cuts in the concrete, coat one of these sections at a time to avoid overlap marks. Otherwise apply the exposed aggregate sealer quickly.

Allow the exposed aggregate sealer to dry for 1-4 hours. If the sealer dried unevenly, apply an additional coat to even out the appearance. Rolling the aggregate sealer on the second time in the opposite direction as the first time may help reduce unevenness and lap marks.

Most exposed aggregate sealers will last 1-2 years depending on climate, traffic, and type of sealer used. Protecting your exposed aggregate concrete surfaces with a quality concrete sealer will enhance their natural beauty and give lasting protection for extended use.

    Can a person use an electric sprayer to apply an aggregate sealer?

      Probably not but does depend on the brand you are using and the sprayer quality as some are too thick.

    Hi. I have an exposed aggregate patio around my pool. I do not want a shiny finish, but would like it to look a little darker to freshen up the look. I am worried about how slick it will be with a sealer. Will the superseal matte be slick when wet, or should I get the superseal M? It didnt sound like the superseal M will darken the patio at all? Is an additive recommended to prevent slipping if I do go with superseal matte?
