I’m in the process of repainting this lovely long mirror as we spruce up our bedroom, but before I can finish, I need to find the right filler to smooth out the corners. What type of filler would you recommend for this project?
Another option is to use painter’s putty for filling in gaps and imperfections.
I think it will need to be sanded
Liette Wolfe suggests using painter’s putty. Take a small ball of it, dip it in 20-minute mud powder, and gently rub it into the crack and nail holes. Works great and no sanding required
I’d simply use DAP Alex Plus to caulk it
You can start by using wood putty to fill in any holes, then sand and repaint the surface.
Hey, consider using a putty that allows sanding if necessary (check out other recommendations). Using caulk won’t allow you to sand it down for a smoother finish if needed.
When applying this product, focus on the corners and then carefully wipe off any excess with a damp cloth. You may need to apply multiple coats for best results.
Or, you could get creative and attach fake flowers to the corners using hot glue. You could also use beads or other materials to add some life to it beyond just painting!
Bondo spot and glazing can be used for very fine lines and small imperfections. 3m also offers excellent pre-mixed spackle compounds that are ideal for larger gaps; they come in quarts and pints.
Sealant
Simply purchase the plastic wood filler. Once it is almost dry, wipe it with a damp cloth and you won’t even need to sand it.
