Great stuff!

Used the primer before I used the liquid rubber. I love this primer. It really does a fantastic job of making the surface waterproof and sticks down any paint that wouldn’t scrape off. A great product

Would highly recommend this product. Easy to use and has created a waterproof and cool balcony.

resurfaced 100 year old cement Koi pond

Pond is 175 square feet and applied 5 quarts of primer and 4 gallons of sealer.
Pond was filled after 72 hours and is leak proof. Very pleased with the product and the technical help from Liquid Rubber.

Applied good. Only problem is seeing were I stopped and started due to the clear finish. I was coating a circular pond.
