OVERCOATING
Where areas need to be over coated due to damage etc., It is important that the area to be treated is well abraded using stiff rotary wire brush or coarse sand paper to give adequate key. Completely strip off any unsound coating and proceed with over coating as for new work.
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 Clear - HD Coating.
Concrete :
Ensure concrete is free from excessive laitance, 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 laitance. 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 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 Clear- HD.
Mixing:
Master Coat Clear - 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.
EQUIPEMENT CARE
All equipment must be cleaned immediately after use with cleaning solvents. Similar procedures should be adopted for break periods exceeding fifteeen minutes.
COVERAGE
3 to 4 sq mtr. per kg per coat. Two coats are recommended.
