How to Remove Caulk From Drywall

John Walker

Caulking of any type is a highly adhesive substance. The material grabs onto and holds virtually any surface. Removing caulk from most surface, such as porcelain or tile, is relatively easy without damaging the surface. However, the porous nature of drywall, causes it to hold onto caulk, making it difficult to remove.

Caulking around a tub can damage drywall or wallpaper if not removed carefully.

A razor blade, some spackle and spare paint can remove caulking without leaving any trace of the material.

  1. Press the edge of a razor blade flat against the drywall with the end of the blade pressed down against the caulking.

  2. Slide the razor blade along the surface of the wall pressing down and through the caulking while maintaining the blade flat against the wall. Repeat the process to ensure that the connection of caulking to the wall was completely severed.

  3. Peel the caulking off slowly. The caulking should remove without any damage at all to the drywall.

  4. Repair any small points of damage with spackle. Spoon the spackle onto the wall with a putty knife smoothing the spackle over with the edge of the knife. Sand the surface of the spackle with 120-grit sandpaper and paint as necessary to hide the damage.
