Multilac High Performance Coatings Waterproofing Sealer

With a 10-year guarantee is an environmentally friendly, fast-drying, penetrating sealer designed to seal porous surfaces and prevent water penetration. It acts as an excellent watertight barrier, bonding effectively to the surface to form a tough, durable, white, and flexible film with superior scrub resistance. This sealer allows for the application of any water-based or solvent-based paint on top after use. It can be applied to common substrates such as concrete, cement blocks, natural stones, gypsum board, statues, walls, pottery, eco bricks, bricks, and asbestos. A key advantage is its ability to be applied to damp areas, as it cures while absorbing moisture and preventing further dampness.

1. Surface Cleaning

  • Remove dust, dirt, loose paint, grease, moss, algae, and efflorescence.
  • Use:
    • Wire brushing, sanding, or pressure washing.
    • Multilac Fungicidal Wash if the surface has algae/fungus – let it dry fully.
    • Surface should be clean, dry, and sound before application.

2. Moisture & Curing

  • New concrete/plaster must be cured for at least 28 days.
  • Surface must be dry (moisture content < 6%) before sealing.
  • Avoid rising damp. If present, fix with appropriate waterproofing treatments.

3. Surface Repair

  • Fill visible cracks (up to 3 mm) and voids using:
    • Multilac Acrylic Waterproof Filler or
    • Multilac Wall Putty (allow to dry and sand smooth).
    • For larger cracks or damaged areas, use cementitious repair mortars or appropriate epoxy fillers.

4. Priming

  • Typically, no separate primer is needed as the sealer itself penetrates and binds the surface.
  • For powdery or highly absorbent surfaces, a diluted coat (10–15% water) of the Waterproofing Sealer can serve as a primer.

5. Application Conditions

  • Apply during dry weather only.
  • Avoid application when rain is expected within 24 hours.
  • Surface temperature: 10°C to 35°C.
