Prepare
Dry, sound, ventilated
Treat any trace of mould with a suitable solution, rinse, and let it dry for 24 hours with the window open. Then wash walls and ceiling: soap, hairspray and limescale leave an invisible film that nothing sticks to. Fill any cracks, sand old satin or gloss paint on the woodwork with 240 grit to dull it, then dust off.
Take off the bath panel, the vanity doors and the towel rail: everything paints better flat. Mask tiles, sanitaryware and taps with tape. On new plaster or a patch that has been damp, use our Wall Primer; on an MDF bath panel or vanity, our Multi-Surface Primer.
