Product Description Granville Galvanised Primer is a primer system specifically designed for use on galvanised metal and zinc alloy surfaces where it will provide improved adhesion for a wide variety of coating systems. Galvanised Primer can be over coated with most water borne or solvent borne topcoats.   Product Benefits * Excellent adhesion * For galvanised metals and zinc alloys   Product Usage Granville Galvanised Primer has been successfully used as a primer system on zinc sprayed, dipped and continuous galvanised metal surfaces, i.e. garage doors, railings, gantries and walkways etc.   Directions for Use It is essential that new galvanised steel is thoroughly degreased prior to painting to remove oil and grease present on the surface. This is best carried out by washing the surface with a suitable solvent i.e. white spirit. Where this is not possible or practical the surface should be thoroughly washed using a suitable detergent, then washed with water and allowed to dry. The product should be applied directly from the container by brush or sponge pad, please note that due to the acidic nature of this product it should not be applied by spray equipment. Once applied the product will react with the surface to produce a black coating. On certain types of galvanised steel a further application of Galvanised Primer may be required to achieve this even colouration. Once the product has dried the surface should be thoroughly washed with clean water and allowed to dry before over-coating with the desired top coat. Immerse brushes, rollers or spray tips in clean water during work breaks. Use water to clean equipment.   Atmospheric Conditions: External: An air temperature of 5 - 30oC (40-80oF) is preferred, avoid applying if relative humidity is greater than 80% or when there is a risk of rain or condensation during the drying period. Internal: Ensure air movement is available to remove excess moisture during the drying process.   Storage Instructions Store in a cool dry area between 5oC and 30oC out of direct sunlight and protect from frost.   Shelf Life 2 years from date of manufacture.   Specification Information Coverage: 8-10sq.m per litre when applied to a wet film thickness of 80 microns (= 40 microns dry film thickness) Over coating Time: Water based topcoat system after 4 - 6 hours, Solvent based topcoat system after 24 hours.   Appearance: Blue translucent liquid Specific Gravity: 1.00 Solubility: Soluble in water when un-cured Flammability: Flammable Flashpoint: >55°C VOC: N/A
