Surface Preparation

New concrete should be cured for at least 1 month prior to paint application. Ensure concrete surface is absolutely dry and free from moisture, oil, laitance, dust and dirt. For old concrete, ensure surface is free from oil, grease, algal & fungal growth and any old coating. Sand Blasting on concrete gives the best performance and should be given first preference out of the available surface preparation methods. If blasting is impracticable, Acid Etching with diluted Hydrochloric Acid followed by fresh water washing to be adopted. Seasoned wooden articles should be scuffed with Emery 220/400 to achieve smooth surface. Please refer our Directive Sheet on Surface Preparation.

Application Data

Application Method

Stir the Base part thoroughly. Mix the base and hardener as per our recommended ratio, by volume. Stir the mix thoroughly to attain homogeneity. Add Thinner Type 290 into the mix, if required, depending on application method, and stir thoroughly for few minutes. Allow the mixture to stand still (maturation) for about 10 minutes to initiate the reaction. Strain the paint through Nylon filter cloth and apply uniformly over the surface. All equipments used for above should be properly cleaned.

Application :-By Brush / By Conventional Spray / By Airless Spray

Generally no thinner is required for Brush application, however under adverse environmental conditions about 5% of thinner, by volume, can be added. Use quality brushes for paint application. Brushes made up of hog bristles are highly recommended. Size of the brush should be in proportion to the work in hand. Large size brushes (100-125 mm) for large areas and small brushes (25-50 mm) for narrow areas should be used.
