Should You Use Wood Filler or Caulk on Trim?
You’ll need to use caulk AND wood filler, or spackling, on any wood trim project.
You should use caulk to fill gaps or joints between trim pieces and/or drywall. Use wood filler, or spackling, to fill nail holes, dents, and cracks on wood trim.
Caulking and filling holes on wood trim takes time. So, don’t try to rush it.
What is the Best Product to Fill Nail Holes in Trim?
For wood trim, wood filler or spackling should be used to patch nail holes, dents, damage, or cracks on a single board or piece of molding.
I prefer spackling over wood filler because it sands smooth quickly and with less effort than wood filler. But, both work.
I highly recommend using your wood filler, or spackling, before caulk. Apply the filler everywhere you need it and let it dry completely. Then come back and sand it smooth.
I like to use sanding sponges or this little gator zip sander to sand flat areas smooth. When everything is sanded, wipe away the dust before moving onto caulk.
You can find the exact order I use to prep wood trim for paint below!
How Do You Fill Gaps in Wood Trim?
For wood trim, caulk should be used to fill gaps anywhere 2 surfaces meet – like, where 2 trim boards meet, where trim and a wall or ceiling meet, or where trim and molding meets.
Caulk can start drying pretty fast, so work in small sections.
And, always be sure to wipe away excess caulk before it dries. Caulk cannot be sanded or easily removed, once dry.
Apply a thin bead of caulk along any gaps, so you have less excess to wipe away. Wipe that bead of caulk into the gap. Apply more where needed to fill the gap.
Like I mention in the video below, there are a few ways to wipe away excess caulk.
The caulk I use recommends a damp sponge, but on textured surfaces sponges can leave little bits of sponge in your caulk. That’s no good.
I get a better result using a damp rag. Other people like to use dry paper towels. None of these are wrong.
Pick the technique that you feel most comfortable with to get the best looking finish.
