FOR WEATHERPROOFING APPLICATIONS TO CONCRETE BLOCKS, CLAY BLOCKS, LIGHTWEIGHT AIRCRETE BLOCKS, BRICKS, ETC. SPRAY TEXTURED & SMOOTH SPRAY TEXTURED - Apply a level, compact minimum 13 - 15 mm thick first coat. Allow to dry and then spray the Textured finish. The Smooth Textured appearance is obtained by pressing a plastic or stainless-steel float over the stiffened but not dry Textured finish.

SCRAPED FINISH - Apply a level, ruled compact 18 mm thick coat, level the surface with a straight edge, spatula or trowel flat. Allow to dry (3-16 hours) and depending on the substrate and drying conditions, scrape the surface in small circular motions using a scraping tool, removing no more than 3 mm from the surface.

This scraping process must remove any slight imperfections and bring the application to the specified finished thickness. Each elevation must be scraped at the same stage, as early scraping will result in a slightly darker shade and later scraping in a lighter shade.The minimum finished thickness after scraping is 15 mm.

After scraping, any dust on the surface should be removed by brushing with a clean soft bristle brush. Always stand back and examine the whole surface for blemishes and unevenness. Errors must be corrected at this stage as rectification later is not practical.

FOR DECORATING WATERPROOF CONCRETE AND MASONRY SUBSTRATES, I.E. COVERED WITH AN EXISTING SOUND AND WEATHERPROOF RENDER, SPRAY TEXTURED & SMOOTH SPRAY TEXTURED - Apply a level, ruled, lined, compact minimum 5 mm-thick first coat. Allow to dry and then spray the Textured coat. The Smooth Textured appearance is obtained by pressing a plastic or stainless-steel float over the stiffened but not dry Textured coat.

SCRAPED FINISH - Apply a level, ruled compact 13 mm thick coat, level the surface with a straight edge, spatula or trowel flat. Allow to dry (3-16 hours) and depending on the substrate and drying conditions, scrape the surface in small circular motions using a scraping tool, removing no more than 3 mm from the surface.
