Understanding the Process
The preparation required for previously painted surfaces is determined by the condition of the previous coating. If the surface is intact and in good condition, it can generally be painted with only a little preparation. Low sheen or matt surfaces in good condition can be painted over after they have been cleaned with Selleys Original Sugar Soap to remove any dirt, grease or grime that may affect adhesion. Glossy surfaces need to be cleaned with Selleys Original Sugar Soap and then sanded to a dull finish with a medium grit (P80) sandpaper. There’s no need to sand back to bare timber, just enough to rough-up the surface so the next coat of paint will have something to grab onto.
Masking before you paint makes the job faster and cleaner. Push the edges of the tape down firmly to ensure straight edges.Ensure the masking tape is removed at a 45° angle before the paint dries completely. If the paint is too dry, the masking tape can rip the paint film when it is removed. If the paint dries before the tape is removed, using a sharp blade, score the edge of the tape before removing so that it doesn’t pull paint away from the wall.
Thoroughly washing walls with Selleys Original Sugar Soap will remove grease and dirt, providing a clean surface that ensures the best possible performance from your finish coats.

Whatever preparation regime you use, it’s critical that prior to painting, the surface is clean and free from any oils, grease or dust. Brush or vacuum the surface to remove any dust and then clean the walls with Selleys Original Sugar Soap, rinse and allow drying before painting.
