Prepare surfaces as for normal painting.
Use Insulprime to prime the surface prior to application of Insultec.
Cracks in masonry: Fibro, masonry: Slate, Tiles. NOT TERRACOTTA:
Colorbond and Unpainted metal surfaces: Non-bleeding Asphalt, Bitumen and Pitch coated surfaces:
Painted surfaces: Timber: RESISTANCE Chemicals: Mould and fungus:
Insultec can be successfully applied over cracks and small gaps by using polyester tape into a coat of wet Insultec and then over coating it with another coat of Insultec.
Wire brush or scrape away surface dirt or fungus.
Repair surface.
Mould, fungus, mildew or algae growth should be treated with a 10% solution of Acticide fungicide.
Carry out repairs to tiles prior to application.
Remove any rust and abrade to bright metal.
Apply a zinc phosphate primer MPC.P.2.
Apply a full coat of solvent based metal primer and allow to dry.
If the metal is badly corroded, two coats of primer may be needed.
Lead or soft alloys can be prepared by using a wire brush to roughen the surface before priming.
This treatment is followed by the usual one or two coats of Insultec Non-ferrous metals can be primed with water based metal primer.
Apply a bitumen primer such as B1500X Bitumen Primer and allow to dry thoroughly before for 24 hours before coating with Insultec.
Gloss surfaces should be well sanded to break up the gloss.
Any other painted surface should be sound and well bonded to the substrate.
Apply Insultec to the prepared surface.
New unpainted timber should be primed with a wood primer.
For previously painted timber, remove flaking and loose paint. Spot prime where necessary. (See “Painted surfaces”) Standard 10% solution of acids and alkalis, including nitric acid and caustic soda failed to cause breakdown of the Insultec membrane. It is impervious to salt spray and shows good resistance to water permeability.
Insultec samples were subjected to testing by the Experimental Physics Department of Main Roads, South Australia.
These tests showed temperature reductions of up to 15 °C.
The membrane which is the vehicle for the special heat rejecting fillers, has been in constant use for more than 20 years.
On particularly bad surfaces it may be necessary to repeat the treatment.
DO NOT WATER BLAST ASBESTOS SURFACES.
Remove surface dirt by wire brushing or water blasting.
