DIRECTIONS FOR USE Surface Preparation : The substrate should be a smooth or semi-smooth sound surface such as concrete or metal. It is most important to ensure that thorough surface preparation is undertaken prior to application of the Master Coat-HD Coating. Concrete : Ensure concrete is free from excessive laitence, grease, oil, curing compound, etc. Ensure concrete is sound. Cut back wherever necessary and make good using suitable cementitious or epoxy repair system. Ensure all blow holes and surface imperfections are made good prior to application of the coating. Wire brushing followed by degreasing, acid etching or grit blasting may be necessary to remove laitence. Ensure concrete is atleast 28 days old. Steel : All previous surface treatments should be removed taking the surface back to base metal. The base metal should be abraded and preferably shot blasted. Cleaning with a solvent or a strong detergent is advisable to ensure surface is free from grease etc. Do not allow surface to re-oxidise before application of Master Coat-HD. Mixing : Master Coat-HD is supplied in two pre-weighted components, Base and Reactor, No additions or omissions are required. Add reactor contents to the base components and stir thoroughly for 3-4 minutes using a slow speed hand drill fitted with a paddle. Mix until a uniform colour is achieved. Apply in two coats. |
