Epoxy Concrete Sealer with UV?

12 years ago

I have an exposed aggregate back patio which I stained, I've been sealing it with Sherwin Williams solvent based concrete sealer for years but the stuff doesn't last (my guess is due to how often it's wet here in Pacific Northwest). The patio is somewhat protected from UV due to a deck above which shields it from sun most of the day except in morning where the angle of the sun hits it.

The Sherwin Williams product only lasts about 6 months and it's very difficult for me to find a time other than summer to apply it due to the amount of rain we get here (I like to have a couple of days before for patio to dry out then couple of days after) but when it dries out in winter finish mostly gone.

I was wondering alternatives to a solvent based concrete sealer, perhaps a Epoxy with UV protectant in it (if such a product exists). Am looking for suggestions.

Thanks for your help!

Look into the silanes and other silicone based penetrating sealers or densifiers.

There is nothing in the realm of that type of quality at HD or Lowes.

You will need to source it from a proper materials supplier but I would keep up on your research.

Siloxane makes some nice stuff.

Look into Thoro products at a concrete or stone supply house, I know they make a lot of very good products. I would definitely stay away from any box or hardware stores for this type of product and Thompson's water seal would NOT be a good product for your situation, stick with a professional type product.
