Seal Krete 100005 Original Waterproofing Primer Sealer Water-Based 5 Gal Clear Seal-Krete Original Waterproofing Sealer is a water based, acrylic application designed to protect vertical concrete and masonry surfaces against moisture penetration. The sealer penetrates deep into the pores of concrete, binding sand and cement particles to form a tough, flexible yet breathable film. It's excellent for binding chalky surfaces to improve paint adhesion on either painted or unpainted substrates. Seal-Krete strengthens mortar joints, reduces efflorescence on brick and acts as a color rejuvenator on older painted or colored surfaces (such as aged vinyl siding and stucco).
