Professional Water-Based Floor Sealer & Base Coat

Actichem Instaseal WB Surface Sealer is a professional water-based floor sealer and base coat, developed to protect porous floors while helping prevent water blotching, scuffing and black heel marks. Its formulation forms a strong bond with porous surfaces, producing a durable, non-slip, low-sheen finish that helps shield against powdering and everyday wear.

Instaseal is also the recommended base coat beneath high-gloss acrylic polymer finishes such as Actichem Instagloss, making it a foundational step in a complete floor-finish system. It is suited to natural stone (including marble, fine stone and slate), concrete, terrazzo, terracotta, pavers and vinyl flooring.

  • Paved surfaces
  • Vinyl flooring

Actichem recommends Instaseal as the base-coat stage before applying a high-gloss finish such as Instagloss.

⚠️ Application & Drying Notes

Instaseal should be applied in 2-4 coats depending on surface porosity and expected traffic, using thin, overlapping strokes with each coat applied at right angles to the previous one. Allow 30-40 minutes drying time between coats, and a minimum of 12 hours before normal floor use. Always consult the current Safety Data Sheet before use.
