Multilac High Performance Coatings Slab Shield 900

As part of a comprehensive waterproofing system, Nano Shield 900 is specifically designed to be applied after Multilac High Performance Nano Sealer 700. It provides an additional layer of protection by forming a hydrophobic barrier that repels water and other liquids, further safeguarding surfaces against moisture intrusion and long-term water damage. Ideal for use on concrete slabs, soffits, balconies, and toilets, it ensures enhanced durability and lasting surface protection.

  • Concrete Slabs, Balconies & Toilets.

1. Clean & Degrease

  • Remove all contaminants (dust, oil, grease, waxes, mold) from the surface.
  • Use wire brushing, pressure washing, or solvent degreasers to thoroughly clean.
  • Repeat cleaning if necessary, flushing with clean water to remove residues, then allow surfaces to fully dry before coating.

2. Remove Weak Material / Laitance

  • Concrete or masonry surfaces may have laitance—a weak, powdery layer—removing it is crucial for good adhesion.
  • Use abrasive blasting (preferred) or acid etching (vertical/horizontal surfaces only, with caution) to open the pores of the substrate.
    studylib.net

3. Mechanical Profiling

  • For hard or smooth surfaces (like cured concrete, epoxy, or tiles), light grinding, shot-blasting, or abrasive finishing provides a texture that improves coating grip.

4. Repair & Patch

  • Inspect the substrate for cracks, holes, or spalling.
  • Use compatible patching compounds or repair mortars, ensuring they are fully cured and dry before proceeding.

5. Final Clean & Dry

  • After profiling and repairs, clean again to remove dust and debris.
  • Verify the surface is completely dry, as moisture impairs the penetration and elasticity of Nano-based coatings.

6. Optional Primer or Test Coat

  • Nano shield coatings often penetrate directly, so primers may not usually be required—check the TDS.
  • For highly porous or variable substrates, consider a light primer or diluted first coat to even out absorption.

7. Test Patch

  • Always conduct a small test area to validate adhesion, appearance, and coverage before full-scale application.
