SSP Joint Seal 600 UV — Polyurea Joint Sealant

Joint Seal 600 UV is a UV-tested, high-performance aliphatic polyurea for sealing concrete joints where both performance and appearance matter. With an exceptional 600% elongation, it flexes and moves with the joint without tearing, separating, or discoloring — and its UV-proof, non-discoloring formula holds its color for the long term, indoors or out. Self-leveling, 100% solids, and moisture tolerant, it’s built for heavy load-transfer joints and high-end polished concrete alike.

Why Joint Seal 600 UV?

Most joint sealants force a trade-off: durable but ugly over time, or good-looking but prone to failure. Joint Seal 600 UV doesn’t compromise. It’s second to none in UV resistance and physical performance — it won’t tear, separate, or discolor, even under heavy use, temperature swings, and sunlight. For projects where failure isn’t an option and appearance counts, it’s a true standout.

Match It to Your Floor

For high-appearance and polished floors, your sealed joints should blend in — not stand out. Tint Joint Seal 600 UV with Joint Seal 600 UV Color Packs (one pack per 32 oz unit) to match the surrounding concrete. Need a specific shade? We offer custom color matching — just provide a Sherwin-Williams reference number.
