How to Paint Over Interior Fire Damage

Fire damage can leave behind persistent odours and unsightly stains that are notoriously difficult to cover with standard paints. These lingering issues not only affect the appearance of walls and ceilings but can also seep through fresh paint, ruining your efforts to restore the space. This guide provides an effective method for blocking odours and stains caused by fire damage, ensuring a clean and stable surface before applying decorative topcoats.

Required Steps

1
Surface Preparation

Remove loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge, vacuum down fire damaged areas to remove dust. Feather sound edges with a fine grade abrasive paper. Prior to painting, the moisture content should not exceed 12%.

For areas with remaining sound paint, clean down with Zinsser Universal Degreaser & Cleaner to remove any contaminants. Rinse thoroughly with clean water to remove all residues.

Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer & Remover 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

Patch prime all bare and filled areas with B-I-N® in accordance with the manufacturer’s instructions. Allow a minimum drying time of 45 minutes in normal drying conditions. Bring forward patch primed areas with B-I-N®. Allow to dry.

For a water-based, low-odour alternative to B-I-N®, use B-I-N® AQUA. B-I-N® AQUA has the added benefit of Trace VOC and easy soap and water clean-up.

Prime all areas to be decorated with one full coat of B-I-N® or B-I-N® AQUA. Allow a minimum drying time of 45 minutes for B-I-N and 2 hours for B-I-N® AQUA in normal drying conditions.
