FAQs

This is commonly caused by moisture beneath the paint film and by paint applied over grey denatured wood, dirt, oil, grease, polish and other surface contamination. Wood movement, such as in joints in window frames, can lead to splits in the paint, allowing moisture to penetrate the wood and cause flaking. To prepare, scrape back areas of flaking or blistering paint to a firm edge and rub down to feather edges using an abrasive paper. If the problem is extensive, strip completely using a hot air gun or chemical paint remover. Clean out open joints with a stripping knife and dusting brush. Make good all open joints and surface imperfections. Treat knots and resinous streaks with one or two coats of a suitable knotting solution before priming with the suitable Dulux Trade Wood Primer.
