How to apply

Clean thoroughly. Prep the areas you’ll seal. Plastics and dirty surfaces need a very clean prep or adhesion suffers.

Tape off vent lids, moldings, front/back caps, and any edges you want crisp.

Apply with a paintbrush around penetrations and seams. The self-leveling formula will flow and settle — don’t overwork it.

Pull tape on time (critical — see below).

IMPORTANT — masking tape removal

Because this is self-leveling and sets quickly, tape timing matters:

Flat / horizontal surfaces & vent lids: remove tape within about 2–3 minutes (no longer than ~5 minutes). It may still be a little stringy while liquid — that’s normal. Pull carefully.

Vertical / sloped areas (front cap rolling to the sidewall, etc.): leave tape a bit longer so leveling can finish — typically 5–8 minutes , up to about 15 minutes if needed. Or wait until the next day and gently score the edge with a razor blade before pulling so the sealant doesn’t tear.
