About this deal
Normally, aluminum roof coatings have a service life of between 3 to 7 years, depending on the surface coated and other factors. per litre per coat depending on the porosity of the substrate. Two coats give a dried film of approximately 0.9mm Can be used with reinforcing or without for damaged and more frail roofs it is recommended to use Scrimtex Glass Fibre Reinforcingor sika 120 fleece
If an aluminum surface roof coating must be applied sooner to a new built-up roof, a water based emulsion coating should be used instead of a solvent-based asphalt coating. An emulsion coating will provide a firm base on which to apply the aluminum coating 5 to 10 days after the emulsion has cured. Note: These instructions follow the recommendations of the National Federation of Roofing Contractors Code of Practice governing the use of Liquid Coatings for Roof Waterproofing. May be used in conjunction with a rot-proof hessian reinforcement scrim or bitumen coated glass fibre scrim such as a Glass Membrane or Scrimtex Glass Fibre Reinforcing. or sika 120 fleece Paint the inside of each lap with 905. Bridge any small gaps and make sure that the membrane is not pulling too tight.Safety recommendation: Do not coat windows, rooflights, glass or translucent sheets. These will constitute a hidden hazard if disguised. Unaffected by water immediately after application can be applied when rain is imminent, not to be applied to wet surfaces
May be used in conjunction with a rot-proof hessian reinforcement scrim or bitumen coated glass fibre scrim such as a Glass Membrane or Scrimtex Glass Fibre Reinforcing. Can be used to bond felt, the waterproofing of guttering not plastic, can also be applied to structural steel work.
Fast drying and unaffected by water immediately after application, can be applied when rain is imminent, and is therefore ideally suited for winter use. Aluminum coatings in the can are typically a bronze color. Thorough stirring will turn the product silver, but it may still have a slight bronze tone while applying. However, as part of the curing process the product “transforms” to create a bright silver film. So even while you’re applying the product, some areas will have turned bright silver while the most recently applied areas are in different stages of turning from silvery bronze to bright silver. This roof coating provides 1.25m² of coverage per litre which varies dependent on the porosity of the substrate. Two coats offer a dried film of approximately 0.9m. Your tools should be cleaned with white spirit or paraffin.
