Cementmix Acid Test
Two concrete blocks, the left block was mixed with Cementmix and the other on the right hand with regular tap water. Then they we’re submerged in acid for 24 hours. The concrete block on the left has remained unaffected, while the block mixed with water on the right has been affected greatly by the acid. Cementmix makes any cement or mortar permanently waterproof through and through.
