Timber and steel windows – paint failure: peeling/flaking
Listed under: Exterior, finishes, metal, steel, timber and wood-based, paint, timber, windows, lead-based paint
Cause
Thermal expansion and contraction of the frame
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint
- caution: old layers of paint may contain lead. Lead can be a health hazard if fumes, dust or paint fragments are swallowed or breathed in. For more information see Health and safety: lead-based paint
Cause
Loss of adhesion due to excess moisture in frame
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint
- caution: old layers of paint may contain lead. Lead can be a health hazard if fumes, dust or paint fragments are swallowed or breathed in. For more information see Health and safety: lead-based paint
Cause
Poor initial substrate preparation
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint
- caution: old layers of paint may contain lead. Lead can be a health hazard if fumes, dust or paint fragments are swallowed or breathed in. For more information see Health and safety: lead-based paint
Cause
water-based enamel paint applied over water-based (acrylic) paint
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint
- caution: old layers of paint may contain lead. Lead can be a health hazard if fumes, dust or paint fragments are swallowed or breathed in. For more information see Health and safety: lead-based paint
Cause
The surface was damp or dirty when painted
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint

- caution: old layers of paint may contain lead. Lead can be a health hazard if fumes, dust or paint fragments are swallowed or breathed in. For more information see Health and safety: lead-based paint
Cause
There has been timber swelling/shrinkage caused by moisture absorption into the timber end grain if the joints were inadequately primed before installation
Repair
- scrape and/or sand paint back to bare timber or until the surface is sound; spot prime as required, then paint with at least 2 coats of semi-gloss or high gloss water-based enamel paint
