Vegam Dampproof

About This Product

Vegam Dampproof uses a high-build rubber-modified latex system that forms a tough, flexible waterproof film on the surface of the substrate. Unlike standard primers, it physically blocks water vapour and liquid water movement through the wall, addressing the root cause of damp patches rather than just covering them.

Use Vegam Dampproof as the first coat on any surface showing signs of moisture ingress, rising damp or water marks — before applying the full primer and topcoat system. Available for both interior and exterior applications.

Ideal Applications

Application Steps

Identify & Fix Source

Before applying Dampproof, identify and address the structural cause of moisture ingress where possible — roof leaks, plumbing leaks or failed waterproofing.

Dampproof will manage moisture transmission through walls but cannot replace structural waterproofing.

Surface Preparation

Remove loose paint, plaster and efflorescence. Clean the surface and allow to dry partially — surface should be damp but not wet for best adhesion.

Apply Dampproof

Apply undiluted using a stiff brush — work into cracks and pores. Apply in a scrubbing action for maximum penetration.

Allow Full Cure

Allow 24 hours cure before applying primer and topcoat system over Dampproof.

Continue with System

Apply Vegam Exterior or Interior Primer followed by appropriate topcoat.

Tools & Tips

Recommended Tools

🔧Crack filler for larger cracks before Dampproof application

Pro Tips

—Do not dilute Dampproof — film thickness is critical to performance.

—For severe damp, apply 2 coats with 24-hour cure between coats.

—Dampproof works best on damp-but-not-wet surfaces — active flowing water requires structural waterproofing first.

—For below-grade surfaces, apply from the positive pressure side (outside face) where possible.

Complete Paint System

Vegam Dampproof is applied before the primer in the paint system, on damp-affected areas only. It does not replace structural waterproofing but significantly extends the service life of the paint system on moisture-prone walls.
