MapeiUltracare Grout Maximizer 26 oz. Bottle

I used this as per recommendation to mix grout for a pool tile repair project. It seemed to work well but I was concerned because there was a slight chaulkiness to the final dried results. So I painted it directly on the grout lines. Wha-la! Perfect! I liked it so much that I used the same procedure to seal small cracks in the pool deck. Worked great!
