Take fibreglass roofing to the next level

Clean off loose material and make the old bituminous felt sound. Humidity Primer seals the porous, aged surface before the mat and base coat go on.

Make sure blisters and cracks are made good first. Aged asphalt is sealed with Humidity Primer so the reinforced membrane bonds across the area.

Dry porous concrete is sealed with Porosity Sealer. Where moisture is present, Humidity Primer or Tecnocem handles damp decks and negative pressure.

Degrease, remove any oxidation and abrade for a key. PU Primer activates bare or coated metal so the system bonds to the non-porous surface.

Clean and activate the membrane with PU Primer, the activator for non-porous surfaces, before laying the reinforced base coat over it.

Overlaying asbestos cement avoids disturbing the substrate. The primer is matched to its condition; confirm the specified primer for the build-up.

Clean the membrane and activate with PU Primer so the reinforced system keys to the non-porous EPDM surface before overlay.

Abrade the gloss and activate with PU Primer, specified for GRP and old coatings, so the new membrane bonds to the existing surface.

Lead is overlaid as a non-porous metal. Clean and key the surface; confirm the specified primer for the system before application.

On a sound timber or OSB deck, Humidity Primer seals the board before the mat and base coat form the waterproof layer over it.
