How To Paint Over Indoor Graffiti

Written By: Zinsseruk

If not treated properly, graffiti can reappear through new paint work. This method explains how to permanently cover up graffiti stains.

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 18%.
Remove all dust. Remove all visible signs of organic growth and treat the areas with Blackfriar Anti-Mould Solution in accordance with the manufacturer’s instructions. Allow to dry.
In areas with sound paint wash with hot water and liquid detergent solution to remove any contaminants, frequently changing the water. Rinse thoroughly with clean water to remove all residues. Allow to dry. Fill any cracks and small surface defects with Ready Patch™ or Ready Patch™ Lite as appropriate in accordance with the manufacturer’s instructions. Allow to dry. Rub down with a fine grade abrasive paper. Remove all dust.

Priming
Prime all areas of graffiti with one full coat of B-I-N® Primer Sealer in accordance with the manufacturer’s instructions. Allow a minimum drying time of 45 minutes in normal drying conditions.

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