MetaShield Insulation and Water-proof Paint is produced under American technology from vacuum microspheres which has very low thermal conductivity. MetaShield enables you to deal with water-proofing and thermal insulation at the same time with the durability under all weather conditions.
B. APPLICATION AREAS
MetaShield can be used for thermal insulation and water-proof purpose on:

F. COATING INSTRUCTION
|Metal roof |
þ Remove any loose matter.
þ Clean dirt, dust, oil and mould with water.
þ Fix hole or crack with compatible paste, sealant.
þ If surface is heavy rust, apply anti-rust Primer RS before apply InsuMax coating.
þ If surface is new, use a light vinagar with water to washout oil and protective compound from the surface.
|Concrete wall |
§ Old wall
þ Remove loose matter.
þ Fix hole or crack with compatible mastic.
§ New wall
þ Let the concrete wall completely cured and dried. (Normally concrete curing time 20 days)
þ Applying suitable mastic when needed. Sanding by sand paper.
