Multilac High Performance Coatings Slab Sealer 700

Multilac Nano Sealer 700 is a solvent-based, fast-penetrating, and quick-drying coating formulated with advanced nanoparticle technology. It effectively blocks microscopic pores in concrete, preventing water infiltration and ensuring superior waterproofing performance. Designed for use on concrete slabs, soffits, balconies, and toilets, it provides long-lasting protection against moisture and water damage.

  • Concrete Slabs, Balconies & Toilets.

1. Clean & Degrease

  • Remove all contaminants such as dust, dirt, oil, grease, rising damp, mold, or previous sealers.
  • Use pressure washing, wire brushing, or a solvent/degreaser as required to thoroughly clean the surface.
  • Let the substrate fully dry (typically 24 hrs for porous surfaces) before proceeding.

2. Profile the Surface

  • Any hard, shiny, or dense surface (e.g.,  concrete, epoxy coatings) must be abraded to create a mechanical key for adhesion.
  • Methods include light shot-blasting, grinding, or acid etching—as advised for similar acrylic sealers.

3. Repair & Fill

  • Inspect the surface for cracks, spalling, or holes.
  • Use suitable repair mortar or filler and allow it to fully cure before sealing coating.

4. Confirm Dryness

  • Ensure the surface is thoroughly dry. Nano-based sealers bond into the substrate, so moisture can impair penetration and durability.

5. Prime (Only if Specified)

  • Most nano-sealer systems penetrate directly and may not require a primer, but always follow the manufacturer’s data sheets.
  • If the surface is highly porous or dusty, a light primer or diluted first coat may help ensure even absorption.
