Acrypol Metal-Kote Waterproof Coating for Metal Roofs – Grey 20Ltr

  • Size: 20Ltr
  • Colour: Gooswing Grey
  • Coverage: 1.7m2 per litre 
  • Suitability: Galvanised Steel, Aluminium, Cast Iron, Tin, Copper, Lead, Stainless Steel, Corrugated Steel, Standing Seam Systems
  • Manufacturer: Acrypol Waterproofing Systems
Description:

Acrypol Metal-Kote is the only metal roof coating that never needs priming – it seals and waterproofs all metal roofs in just one coat.

Rust occurs when unprotected metal is exposed to moisture. Once rust attacks, it can quickly spread and may cause serious structural damage. Metal-Kote coats directly over surface rust with a 100% watertight seal and inhibits rust from spreading. Unlike other coatings on the market, Metal-Kote does not require blasting or sanding to remove rust completely before application, nor does it require a primer before it can be applied.

Recommended coverage is 1.7m²/litre at 600 microns wet film thickness.

Owing to the fact that the Metal-Kote resin is formulated for immediate bonding, the product sets up quickly, forms an instant watertight barrier and skins over in 30 mins to 2 hours.

Suitable for Coating:
  • Coated and Uncoated Steel
  • Galvanised Steel
  • Aluminium
  • Cast Iron
  • Tin
  • Copper
  • Lead
  • Stainless Steel
  • Corrugated
  • Standing Seam Systems
