Great Customer Service and Product
Ordered two of the (5) gallon buckets for the Foundation Sealant. Both arrived very thick and chunky, wouldn’t stick to the roller or the block wall. Called customer service for Petra and spoke with Mikki, she was able to confirm both buckets had went bad. She immediately had two replacement buckets sent out to me directly. After receiving them was able to use the product properly and it works great. Would definitely buy again for future needs. Mikki was also great to work with.

Was not impressed at all
Was like spreading mortar mix. Did not spread evenly with a roller or brush. Maybe i got a bad batch but would not recommend. Took me all day to coat a 24" x 60 foot wall, came off a roller in globs and cloged the brush up so bad it became unusable after ten foot of wall no matter how much i mixed the bucket with a drill mixer and thankfully i get to bury it but the glob mess it creates my boots are ruined. Will not recommend or buy again

Really hard
I opened the container to find their product hard like it was almost dry. I had to get another bucket scoop half out as a little water and mix. It finally came back to life and I was able to use most of it. I don’t know how long these have been on the shelf but it was almost not salvageable. Luckily I got my job done but just be weary of their products and ask them to check the product before shipping it.

Doesn't spread. Keeps clumping. Awful.
