If it's in good order then a simple re-coat will usually suffice, however if the paint is old, flaky and discoloured then it will need to be removed, the frame sanded back and then fresh paint applied to produce a decent finish. Use our guide below to help ensure you produce the best finish possible to your existing window frame;.
If the existing paintwork is in a poor condition with several cracks and large flaking areas, the best result will be achieved by stripping the paint off back to the bare wood. This can be achieved in a number of ways using either tools and 'elbow grease', or chemicals.
Home testing kits are available from DIY stores to confirm the presence of lead, but if in any doubt, use a chemical stripper to remove this paint. Do not use sandpaper or heat guns which can spread lead particles or fumes. Site Pages. Providing none of the timber is exposed, apply a coating of undercoat over the filler and, once dry, smooth down with a fine glass paper, feathering the edges onto the surrounding paintwork. If timber is exposed, apply a coating of primer and feather that into the surrounding area before applying the undercoat.
NOTE: The undercoat may not be necessary if the final coat will be a 'Single Coat' paint although it does help to disguise the repair. The procedure is as follows:.
Using a chemical paint stripper - follow the manufacturer's instructions, use plenty of newspaper or other protective material to protect the flooring and surrounding areas. Keep the area well ventilated. Start at the top and work downwards using a scraper to lift the paint off once the stripper has caused it to lift.

The sharper the scraper, the easier it will be to remove the failing paint. For best results, equip yourself with a scraper that has a hardened steel or carbide edge.
Sand down the edges of bare spots. You can do away with these imperfections easily using a handheld power sander. Start with a low-grit sandpaper of around grit or so to grind down sharper edges. Then, switch to a high-grit paper grit or higher and smooth the paint down to the underlying wood. If ignored, old paint lines can create seams under the new topcoat, which can become prone to cracking as a result. Treat exposed wood knots separately with a preliminary primer.
Certain types of wood, like pine and cedar, give off sappy resins that can bleed through thin and light-colored paints. These spots should be brushed with a special resin-blocking primer to prevent discoloration. Apply the primer over any sections of the wood where the grain looks particularly dark or wet. Sand the entire surface. Sweep an orbit sander over the wood in wide circular strokes.
The light scuffing action will produce a more textured surface that promotes proper paint adhesion. Be sure to sand away any wood splints, as well. A thorough sanding should rough up the exterior enough to help fresh coats stick. Wipe the surface clean. Sweep the wood with a stiff-bristled brush or dry cloth to remove the dust generated by sanding.
Blow sharply to force lingering dust out of narrow cracks and holes. The surface should be totally free of debris when you're finished. Drag your finger along the wood to make sure no traces of dust remain. Paint has a hard time adhering to surfaces that are coated with lots of fine particles. Part 3. Choose a latex-based primer designed for exterior use.
These products hold up better to the sort of heat, moisture, rubbing, and swelling that outdoor wood surfaces are often subjected to. They have the ability to flex a little, which makes them less likely to crack than paints that dry into a hard shell.
As a result, your paint job will look better and last longer. If it's too hot or too cold, it may not dry with the right consistency. Brush on a coat of primer. A roller will make it easier to spread the primer over broader areas. For smaller surfaces and tricky structures like railings, a handheld brush will offer the greatest amount of control. Apply the primer in an even layer thick enough to completely conceal the wood grain underneath.
