Ramuc PSL Nitrile Rubber Pool Sealant
Ramuc PSL is a flexible nitrile rubber caulk made for pools. It seals expansion joints, fills cracks up to ½ in wide in walls and steps, and seals tile grout lines. It stays flexible as the pool moves with temperature and water pressure, bonds even in wet conditions and cures underwater. Paint over it with any Ramuc pool paint after 24 hours.
Key Features
- Stays flexible from -1 °C to 79 °C, with 100% elongation.
- Non-sag for walls, steps and sloped surfaces.
- Bonds wet and cures underwater.
- Tack free in under 10 minutes.
- Paintable in 24 hours with any Ramuc pool paint.
- No primer needed on most surfaces.
Where to Use It
Pool expansion joints, cracks up to ½ in wide in walls, steps and sloped areas, and grout lines in tiled pools. Use it before Ramuc Clean & Prep and painting with Ramuc DS, A-2, EP Epoxy or Hi-Build Epoxy. For holes, gouges and larger repairs, use Ramuc Epoxy Patching Compound. Not for structural glazing, tuck pointing or hot surfaces.

Application Guide
- Clean out the joint. Remove old caulk, dirt and loose material. Wire brush or grind for a rough surface that grips.
- Add backer rod if the joint is deeper than ½ in.
- Tape the edges if you want a clean line.
- Gun it in so the bead sits slightly above the joint, to allow for shrinkage as it cures.
- Paint after 24 hours.

FAQ
1What is Ramuc PSL used for?
Sealing pool expansion joints, filling cracks up to ½ in wide in walls, steps and sloped surfaces, and sealing grout lines in tiled pools. It stays flexible, so it moves with the pool instead of cracking.
2Can I paint over PSL?
Yes. Wait 24 hours, then paint with any Ramuc pool paint.
3Can it go on a wet surface?
Yes. It bonds in wet conditions and cures underwater. For the best bond, start with a clean, sound joint free of old caulk and dirt.
4How wide a crack can it fill?
Up to ½ in wide. If the joint is deeper than ½ in, put foam backer rod in first. For holes, gouges and larger repairs, use Ramuc Epoxy Patching Compound.
5Does it need a primer?
Not on most surfaces. Roughening the surface with a wire brush or grinder improves the bond.
