Akona Concrete Bonding Additive - Liquid Concrete Strengthener & Bonding Agent, Acrylic, Increase Strength in Cold Weather, Admixture (Gallon, 1)

I use this product when I tiled my front porch stoop this summer. From what I can tell, it worked very well. Tile job was success and its holding up very well so far and is holding up during our cold Wisconsin weather.

Had a horrible smell like it was spoiled used once and tossed. Would not buy again

Fair price for the product. Directions only mention mixing, not the ability to brush it on existing concrete like other bonding agents, but the listing pictures show it being brushed on which is confusing. It's supposed to be used as a substitute for water which means you would use a lot of it fairly quickly. It works well, especially if it protects against freeze/thaw. We'll see once the winter comes.

This bonding agent works great!I have used acrylic bonding agents like this many times in multi million dollar construction projects as well as everyday home repairs and sculpture projects.This bonding agent paired great with fast set hydraulic cement to stop leaks. For extra stability, just add chopped fiberglass.This is a great product. Would recommend.
