Required Steps

1
Surface Preparation

All surfaces must be clean, dry and free from anything that will interfere with the adhesion of the materials to be applied. Remove loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge. Feather sound edges with a fine grade abrasive paper. Prior to painting, the moisture content should not exceed 12%. Remove all dust. In areas with sound paint clean down with Zinsser Universal Degreaser and Cleaner to remove any contaminants. Rinse thoroughly with clean water to remove all residues. Allow to dry.

Treat exterior mould with a proprietary mould killer and remover in accordance with manufacturers instructions. Fill any cracks and small surface defects with a suitable filler in accordance with the manufacturer’s instructions. Allow to dry. Rub down with a fine grade abrasive paper. Remove all dust.
