How to paint undecorated water stained surfaces

Water stains have a tendency to reappear through fresh paint work if they aren’t properly blocked.

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 material by scraping or brushing with a stiff bristle brush to a sound edge. Prior to painting, the moisture content should not exceed 12%. Remove all dust.
Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer in accordance with the manufacturer’s instructions. 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 in accordance with manufacturer’s instructions. Allow a minimum drying time of 45 minutes in normal drying conditions.

3. Decoration

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