How to paint interior mildew areas

Zinsser Perma-White® blocks fungal degradation permanently as well as providing a decorative finish.

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. Remove all visible signs of organic growth and treat the areas with an efficient mould killer in accordance with the manufacturer’s instructions. Allow to dry.

In areas with remaining sound paint wash clean down with Universal Cleaner & Degreaser to remove any contaminants. Rinse thoroughly with clean water to remove all residues. Allow to dry. Fill any cracks and small surface defects with a suitable filler as appropriate in accordance with the manufacturer’s instructions. Allow to dry. Rub down with a fine grade abrasive paper. Remove all dust.

2. Priming

Prime all areas to be decorated with one full coat of B-I-N® Primer Sealer. Allow a minimum drying time of 45 minutes in normal drying conditions.

3. Decoration

Decorate with two full coats of Perma-White® Interior Matt or Satin in accordance with the manufacturer’s instructions. Allow a minimum drying time of two hours between coats.
