SWP SEALTIGHT

SWP SealTight is a superior clear concrete sealer that deeply penetrates (2–4") into the surface to permanently protect concrete and masonry from moisture, salt, efflorescence, and surface deterioration. Unlike surface-only sealers like siloxanes or solvent-based coatings, SealTight chemically bonds within the substrate for long-lasting performance — without flaking, yellowing, or peeling.

✔️ Deep penetrating (not just a surface film)
✔️ Increases substrate strength and resists spalling
✔️ Dries clear — no sheen, no discoloration
✔️ Non-toxic, non-flammable, and ultra-low VOC
✔️ Compatible with Maxseal Flex, Drizoro repair cements & coatings
✔️ Allows coating over with paint, epoxy, or acrylics
✔️ Encapsulates alkali to reduce efflorescence and extend coating life

Recommended For:
Basements, garages, retaining walls, driveways, concrete tanks, and surfaces requiring deep waterproofing.
