Exposed Aggregate Sealer and Coatings

exposed-aggregate-sealerExposed Aggregate patios, driveways, and walkways are decorative stone surfaces commonly used in residential and commercial landscaping. These surfaces require a coat of a new sealer to provide protection and enhancement to the substrate. This Exposed Aggregate Sealer is typically applied every 1-3 years depending on the exposure and traffic.

There are many advantages to sealing an exposed aggregate surface:

  • Gives surface a richer color and added shine
  • Protects from winter salts
  • Seals from hairline cracks and pitting of aggregate

Sealing Exposed Aggregate is very easy and any residential homeowner can do this with ease.

Prep Aggregate First

  1. Clean surface with a pressure washer to remove dirt.
  2. If needed use a concrete cleaner to remove stains such as grease or rust.
  3. After drying for 24-48 hours, apply a exposed aggregate crack filler to any large cracks.

 

Apply Exposed Aggregate Sealer

  1. Using a roller, apply sealer and a spread rate of 100-150 sq. feet per gallon making sure not to puddle the sealer.
  2. Let dry for 1-3 hours
  3. If needed, apply a light second coat to even out the appearance or increase the gloss level

 

Maintaining Your Exposed Aggregate Surface

Typically it us best to repeat this process every 1-3 years to keep your aggregate protected and looking great.

Will one of the above mentioned products help make the exposed aggregate easier to walk on? Over the years some of the cement has deteriorated and exposes more of the rocks and it is getting a little uncomfortable to walk on. The area is around a pool and gets a lot of traffic. Also, will one of the products make it less hot to walk on?

Sonia, sorry but a sealer cannot make a surface "easier" or less "hot" to walk on.

How does Super Seal 30 compare with more expensive Glaze N Seal Wet Look Green Lacquer and is it legal to be used in California? Is it sold in any Calif. businesses?

I forgot to ask but is S.S. 30 the best product in your line for 20 year old exposed aggregate that has never been coated. Also will one coat using 100 sq. ft. per gallon coverage do this driveway?
ronald hulse , August 25, 2015
...
SS30 is not legal for CA. You can use the SS VOC version there. One coat will cover about 100-125 sq. feet.

My agregate driveway has some flaking of the material. Will a sealer help? There is also a crack. Will a sealer fill this?
Gerald zel , May 11, 2016
re: Will a sealer help
Aggregate sealers do not fill cracks nor do they fix flaking material.

I didn't realize that you needed to allow the aggregate to dry for so long after cleaning it! I'm really glad you mentioned it--we're going to be getting our driveway redone in it and want to make sure it lasts for as long as possible. When we're getting it sealed, I'll make sure it's given enough time to dry before applying the sealer!
