Reflective bitumen-based aluminium paint.
silvakote is a one pack, aluminium pigmented bitumen solution.
Uses
UV reflective and protective aluminium paint for exposed concrete and metal roofs, polymer modified bitumen waterproofing membranes, liquid applied bitumen waterproofing and general bitumen coatings.
Advantages
- UV resistant.
- Highly reflective.
- Easy-to-apply.
Surface Preparation
Any surfaces to be coated with silvakote must be clean, mechanically sound and dry. It is recommended that surfaces be checked with a moisture meter before coating.
Steel – should be free of rust and loose material as well as oil, grease and loose paint.
Galvanised steel – should be free of loose paint, grease and in the case of new material, free of anti-white rust treatment.
Bituminous surfaces and sheet waterproofing membranes – should be free of dust, chalking and any other loose material. New bituminous surfaces should weather for 8 weeks before coating.
Colour
Bonding / Priming
silvakote is normally applied directly to the surface but the following priming systems may be used where conditions so dictate.
Steel – etch primer, like a.b.e® 4-metal primer.
Galvanised steel – no priming needed.
Bituminous surfaces – no priming needed except on ‘hungry’ sheet waterproofing membranes where a coat of must be applied. Bitumen surfaces must be allowed to weather for 8 weeks before coating.
Mixing
As the aluminium pigment settles very easily silvakote must be stirred well before use, using a flat paddle. All settled material must be thoroughly dispersed. Keep silvakote well stirred during use.
Typical Physical Properties of Wet Material
Coverage
Steel and galvanised steel: 14 m2/1 L @ 60 µm wft, resulting dft: 20 µm. Bituminous surfaces: 6 – 8 m2/1 L. Minimum two coats.
Application
silvakote may be applied by conventional spray or by brush or roller. On large applications it is often applied by soft broom or roofing mop. Coverage is very dependent on the porosity of the surface.
Cleaning
Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.
Protection on Completion
It may be necessary to apply a further coat of silvakote after three years.
Packaging
1 L, 5 L, 25 L, 200 L containers.
Handling & Storage
This product has a shelf life of 12 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.
Caution
Due to the viscosity and aluminium pigments contained in silvakote this product exhibits both high spread and hiding characteristics. Low film build should, however, be avoided in the interests of longevity with due care during installation to apply the specified coating thickness.
Health & Safety
Product safety information required for safe use is not included. Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information. The safety data sheet is available from your local a.b.e.® Construction Chemicals branch.
