Deck-O-Seal 32 Oz. HS-1 SL One-Part Self-Leveling Hybrid Joint Sealant, Gray

Deck-O-Seal HS-1 SL is a one-part, self-leveling hybrid joint sealant, and this is the 32 ounce gray container, part number 4708322. It is built on silyl-modified polymer (SMP) technology, cures from atmospheric moisture, and sets up as a medium modulus sealant with strong adhesion and good resistance to aging and weathering.

How it works

Because it is one part there is nothing to mix. Poured into a horizontal joint it levels itself, so the finish comes out flat without tooling. Once it has cured it moves with the joint rather than cracking away from it, which is the job of a medium modulus sealant in an expansion or control joint.

Ordering

This is the gray color in the one quart size. Estimate the joint length and cross section you have to fill and order enough containers to finish the run in one pass.
