Our GBS Penetrating Concrete Sealer penetrates 3-4 inches into the cinder block and permanently stops moisture penetration. It also carries a 15 year warranty against water intrusion as long as it is applied properly. This assumes, that the cinder blocks are completely dry and have not been previously sealed or painted. It is zero VOC and has no odor when dry. When using on a wall, it will require 3-5 coats to saturate the block as gravity is not working in your favor.
