Interior Walls

Pre-painting

• Check surface for incidence of dampness or water seepage.
• Rectify the water seepage problem at source. This could mean repairing leaking pipes or cracks in the exterior walls.
• Any loose plaster should be removed from the wall. Check for loose plaster by tapping on the walls. A hollow sound indicates loose plaster.
• Masonry work is to be undertaken to fill up all cracks and repair broken plaster
• Please ensure proper curing time (7 to 21 days depending on extent of plastering). When re-plastering is done it should be given proper drying and stabilising time to bridge the cracks or smoothen the surface.

Surface Preparation

• Allow newly plastered surfaces to mature for a period of at least 6 months after the application of a coat of lime ash to ensure thorough drying of plaster. Popping of plaster commonly associated with new plasters can be taken care of subsequently during painting.
• Remove loose particles and paint flakes. Scrape with sandpaper to ensure that the surface is dry and free from dust, dirt or grease.
• Previous coatings of lime wash or powder distemper or cement paint must be thoroughly scraped off. Earlier coatings of oil or synthetic emulsion paints, if in good condition, need not be removed. However, the gloss or sheen of such coating must be removed by thorough sanding.
• Cracked or flaked paint must also be completely removed.
• Fungus affected areas need to be given a separate treatment. Use SCIB Etch on plastered surfaces or make a 5-10 % solution of bleach powder in water and apply on affected areas with brush or sponge. For both cases, wash the walls with clean water after an interval of 8-10 hours. Allow the surface to dry sufficiently.

Painting

• Apply SCIB Seal Coat 101/101W or 102 AR on putty for new surfaces or previously painted surfaces with water based paint if in good condition or SCIB Alkyd Undercoat for alkyd painted surfaces if in a good condition.
• Fill and level the minor undulations of wall by applying SCIB Acryputty or EL Breemo putty. In case of major undulations on the wall surface, for best results use Unoshield or Stucco Scimical Putty. Ensure that the surface is uniformly smooth by sanding after putty work.
• One liberal coat SCIB Seal Coat Wall Primer (water thinned) is recommended on puttied areas before the application of top coat. The primer should be allowed to dry for 10 - 12 hours. If the primer coat is not applied over the puttied areas, there can be a patchy appearance of the top coat.
• Fill up deep cracks with SCIB In case of movable cracks (between trim and wall...), use SCIB Acryseal Mastic.
• All external drainage pipes must be checked for rusting or leakage. Any faulty plumbing must be rectified
• Special attention must be given to the roof. Check for cracks near the edges and close to the water reservoirs. Proper masonry or waterproofing work on the ceiling will enhance the performance of the paint.
