Ready-to-use formula penetrates deep into concrete and masonry where it chemically reacts with siliceous materials to form a hydrophobic barrier to prevent the absorption of water and waterborne chloride ions. STIFEL 100 has a small molecular structure allowing it to move through concrete pores and penetrate deep, up to 1/2 inch or more.
