High build one coat finishing system for renovation for factory coated profile metal sheeted roof and cladding panels, roofing trims etc. Raincoat HB Smooth is a single pack smooth finish based on a specially modified acrylic/urethane resin system containing inert pigments, extenders and flame retardant agents.
Raincoat HB smooth for roof and cladding panels comes in Light Grey 10A05 stocked in 12.5 lt, other colours made to order.
Apply with a brush, roller or airless spray. Stripe coat all vulnerable areas, (edges, panel ends, bolt heads, etc) and allow to dry before main coat application.
Ensure surfaces are sound, clean and dry before coating, and any existing coatings are sufficiently resilient for overcoating. Additionally, remove surface contaminants by detergent scrubbing or high pressure power washing. Then, remove any moss, lichen, algae, etc using. Ensure any existing coatings are adhering firmly to the substrate. Remove any residual chalking (if present) by vigorous rubbing, etc with a fine scouring pad (eg. “Scotchbrite”), and any other surface leachates or residues (particularly on plasticised PVC coatings) by either vigorous wiping with Tor TH99 solvent or vigorous scrubbing with strong alkali detergent (eg. Torstrip WDA10) followed by thorough rinsing.
Note: Abrasion of PVF2 coatings (other than around loose or corroded areas) with fine hard abrasives (eg emery, carborundum, sandpaper, etc) may impair adhesion of subsequent coatings. Coarse white aluminium oxide papers (80 mesh or coarser) recommended to cut and roughen coatings. Scrape back any loose or weakly bonded materials and prepare to a firm feathered edge, and abrade exposed metal to remove corrosion products and provide a mechanical “key”. Spot prime all bare metal areas with Raincoat APA (RC353) as appropriate. Stripe coat vulnerable areas (drip edges, exposed bolt heads, panel edges etc) with Raincoat™ Fibretex or Raincoat™ Cladding Finish as appropriate.
