SP Seal Coat is a one-component coating that combines three high-performance water-borne resins into an elastomeric, self-cross-linking system. It’s engineered for long life, weathering resistance, and resistance to ponding water — the conditions that typically destroy a roof topcoat. It also resists mold and mildew, stays flexible through thermal cycles, and releases dirt well.

Hawaiʻi’s combination of intense UV, rapid temperature swings between sun and shade, and heavy seasonal rain is brutal on rigid topcoats — they crack at thermal joints and let water through. SP Seal Coat stays flexible and self-cross-links over time, so it holds its waterproof seal even as the substrate moves.

No. For direct-to-metal applications, prime first with Super Base or another appropriate primer. SP Seal Coat is then applied over the primer.
Yes — it’s specifically engineered to resist ponding water, one of the most common reasons a roof topcoat fails.
Standard SP Seal Coat is for ambient-temperature surfaces. SP Seal Coat HT is for sealing over HPC® on hot pipes and equipment (up to 260°C / 500°F).
