Question: A carpenter is installing interior trim and notices small gaps between the casing and the wall surface after fastening. What is the most effective way to eliminate these gaps for a professional finish before painting?

Answer options:

  • Apply an extra coat of paint over the gaps.
  • Shim behind the casing with thin shims until snug.
  • Fill the gaps with wood putty before sanding. ✅ Caulk the gaps with an acrylic latex sealant after installation.

Correct answer: Caulk the gaps with an acrylic latex sealant after installation.

Explanation: Caulking the gaps with an acrylic latex sealant is the standard and most effective method to fill small discrepancies between trim and the wall surface, creating a seamless appearance ready for painting. Shimming is done during installation to straighten trim, and wood putty is typically for nail holes or minor surface imperfections, not gaps along a seam. Painting over gaps will not conceal them effectively.
