Fast drying and unaffected by water immediately after application, can be applied when rain is imminent, and is therefore ideally suited for winter use. Can new built-up roofs be coated with aluminum coatings sooner than the recommended 90 to 180 days weathering period? Aluminum coatings do not perform well on roofs that pond water. Dirt can accumulate in depressions and inhibit the reflectance of the coating. If an aluminum coating is under water for a prolonged period of time, the water may work its way under the coating causing it to peel. Positive drainage is needed to flush away surface dirt and retain the reflective properties of the aluminum coating.

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. 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. Apply two coats of 905 to the warm side of the wall. Make sure to avoid pinholes. Once dry, apply the insulation over the top of it.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.

Normally, aluminum roof coatings have a service life of between 3 to 7 years, depending on the surface coated and other factors.Preparing the surface is incredibly important and will impact the amount of adhesion and life of the renovation. All coated roof surfaces should be clean, stable, sound and free from loose debris, grease, dust and dirt. All hints of fungi and algae growth should be completely removed with a stiff-bristled brush and surfaces should be treated with Everbuild fungicidal wash to destroy any residual spores and prevent the return of growth. Can be used to bond felt, the waterproofing of guttering not plastic, can also be applied to structural steel work. Aluminum coatings should be a uniform, bright silver when dry. Several issues can contribute to creating a non-uniform appearance, including overlapping, improper mixing. rain, dew or snow.
