A flexible, low-porosity acrylic film that resists water absorption and moves with temperature changes without cracking.

Satin / Semi-Gloss Finish

The sheen level matters in a bathroom — satin and semi-gloss repel moisture and wipe clean, where flat paint absorbs it.

Advantages

  • Easy to wipe clean
  • Repels moisture better than flat
  • Hides minor surface marks

Disadvantages

  • Shows wall imperfections more than flat
  • Higher gloss can look clinical

A sealing coat that helps the topcoat bond and stops stains bleeding through — important over new linings and fibre-cement sheet.

Advantages

  • Better topcoat adhesion
  • Seals porous surfaces
  • Blocks stains

Disadvantages

  • Extra step and cost
  • Must match the surface and topcoat
