Moisture Barrier Timber Flooring Adhesive – Epoxy Sealer EPR-31P
Epoxy Sealer EPR-31P is a high-performance, two-component epoxy-based moisture barrier and sealer, designed to suppress rising damp and residual construction moisture in porous subfloors. Ideal for pre-treating porous mineral subfloors before the application of Soudal's timber flooring adhesives, this durable and moisture-resistant primer enhances adhesion and structural integrity.
Key Benefits:
✅ Two-component epoxy sealer – Ensures high mechanical strength
✅ Moisture-resistant formulation – Suppresses rising damp & residual construction moisture
✅ Compatible with porous & non-porous substrates – Versatile for various flooring types
✅ Suitable for underfloor heating – Withstands thermal movement
✅ High shear, compressive & tensile strength – Ensures long-lasting performance
Typical Applications:
✔ Sealing & pre-treating mineral subfloors (cement, concrete, calcium-sulfate, anhydrite, and levelled surfaces)
✔ Enhancing adhesion on wooden subfloors & chipboard
✔ Application on terrazzo, ceramic tiles & metal surfaces
✔ Suppressing residual construction moisture in subfloors
Application Instructions:
-
Acclimatise the Epoxy Sealer EPR-31P to room temperature before use.
-
Mix components thoroughly:
-
Punch through the plastic plug of Component B (upper container) to allow it to drain into Component A.
-
Use a variable speed electric drill with a mixing paddle to mix for at least 2 minutes until homogeneous.
-
Do not deviate from the prescribed mixing ratio, as it affects curing and mechanical performance.
-
Apply within 30 minutes after mixing:
-
Use a paint roller or brush – Avoid pouring directly onto the floor to prevent puddles.
-
For highly porous subfloors, apply a second crosswise coat after the first has dried.
-
For added adhesion, throw in quartz sand immediately after the second layer.
-
Allow complete drying before further flooring applications – Prevents crater formation and adhesion issues.
