Smoke damaged surfaces


From the Resene paint and decorating problems solver

The chemical composition of smoke is dependent on the composition of the material that is being burnt. As well as containing particulate carbon, smoke may contain a wide range of staining substances both solvent and water soluble. It must always be assumed that both types of substance are present in any smoke damaged area. When cleaning smoke damaged surfaces, experience has shown that the most effective cleaning is achieved by the use of Resene Emulsifiable Solvent Cleaner. This is scrubbed onto affected areas, where it will dissolve up most of the solvent-soluble stains. The affected areas are then washed with water, which emulsifies the stain-laden solvent and dissolves the majority of water-soluble stains.

Thoroughly scrape and sand to remove all loose and flaking paint and to provide a key for subsequent coats. Ensure all areas of flaked paint are thoroughly sanded to a feathered edge. Sand any sharp edges to give a rounded edge. Remove all sanding dust.

Smoke Damaged Surfaces

Despite the above washing procedure, remnants of stains will be left on the surface.
