This guide explains how to prime brickwork properly to ensure excellent top coat adhesion.
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 18%.
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.
Rake out and re-point any unstable pointing with a suitable cement mix in accordance with the manufacturer’s instructions. Allow to cure.
Patch prime all bare and filled areas with Bulls Eye® 1-2-3 Primer Sealer in accordance with the manufacturer’s instructions. Allow a minimum drying time of 1 hour in normal drying conditions. Bring forward patch primed areas with Bulls Eye 1-2-3® Primer Sealer. Allow to dry.
Prime all areas to be decorated with one full coat of Bulls Eye® 1-2-3 Primer Sealer in accordance with the manufacturer’s instructions. Allow a minimum drying time of 1 hour in normal drying conditions.
Decorate with two full coats of AllCoat® Exterior Satin or Gloss in accordance with the manufacturer’s instructions. Allow a minimum drying time of 1 hour between coats in normal drying conditions.
