Tips for Preparing a Wood Trim before Painting It

Wooden FloorTaking time to prepare the surface of a wood trim before painting it can help achieve a beautiful and durable finish. Whether you want to paint an old or new wood trim, you may need to fill all the gaps and holes and smoothen the surface before applying the finishing enamel. Below are tips to prepare a previously painted or bare wood trim for painting.


Experts from Miskas Wood Products explain that you may need to hire a professional wood trim and molding provider to scrape your previously painted wood trim. Alternatively, one can use a sharp object, such as a knife, to force off all the loose, peeling paint at the edges of the wood. After that, use sandpaper with 80 grit to sand these spots, followed by 120-grit sandpaper to force off the remaining paint. You can use a duster or vacuum cleaner to remove the sanding dust before applying oil-based undercoat on the surface.

Filling Gaps and Holes

Once the primer has dried up, use trim spackle and wood putty to repair all large holes and gouges. You can also use painter’s putty to fill all small nail holes and acrylic latex for filling gaps on the edges where wallboards meet. Once you’ve filled all the gaps using caulk, use clothing to wipe off the excess filler before it sets up.

Removal of the Old Paint

Old paint often leaves a patchwork of paint chips on the surface of wood trim. That means that one has to remove the patches left on a block of wood to restore a beautiful finish. You can use a paint heat gun to bring the entire wood trim to the same level of smoothness.

Whether you applied paint before or after finishing a wood trim, it’s crucial to prepare the whole surface before painting it. However, be sure to wear a dust mask and protective gloves when sanding the wood. You could also need to paint the wood trim in an adequately ventilated room to avoid suffocation.
