SUSTAIN KRETE 5 gal. Sustain Krete Concrete and Masonry Water and Salt Repellent

If left untreated, concrete will absorb water into its pore network. When this water freezes it expands within the concrete and causes damage from the inside out. Sustain Krete is a soy-based sealant that is absorbed into the pores near the concrete's surface, creating a hydrophobic barrier which blocks water and salt. Perfect for major highway projects, bridge construction and other large-scale roadway infrastructure applications, this new penetrating concrete sealer can provide seven to 10 years worth of protection against water, salt and the freeze-thaw damage. Even already damaged concrete will benefit.
