THE SURFACE PREPARATION OF CONCRETE AND THE APPLICATION OF SURFACE COATINGS
This article describes some methods of cleaning concrete surfaces, and selecting and applying coatings for concrete. British Standard BS 6270, Part 2 and the US Standards ASTM D4258 and ASTN D4259 give advice on cleaning and abrading concrete surfaces. Methods suggested for cleaning include mechanical wire brushing (for small areas), high-pressure water jetting, applying a proprietary fungicidal wash, abrasive drying (wet, dry, or vacuum), mechanical impact techniques such as needle gunning or bush hammering, and mechanical abrasion. There is a wide range of final protective and decorative coatings for concrete. Many factors may influence the selection of coating, including the state of the concrete substrate, maintenance cycles, environmental issues, colour, desired finish appearance, and available budget. The main two types of coating are inorganic and organic. Inorganic coatings include low-cost decorative cement-based masonry paints and thicker, more protective, more expensive polymer-modified cementitious coatings. Organic coatings may be classified into thermoplastics and synthetic rubbers, alkyds and drying oils, bituminous materials, and thermosetting polymers. The three main methods of applying coatings to post-fabricated concrete structures are by brush, roller, and spray.
