Filling Deep Gaps & Masking Edges Cleanly
If an uneven wall or a series of packers leaves a gap behind the frame that is too deep for decorators' caulk alone, standard caulk will often shrink or crack as it dries. Solve it with a two-layer method: hybrid polymer adhesive as a firm backing filler, then a final caulk finish.
Supply-only guide. Shutter Pros supplies made-to-measure shutters that you collect from us, then measure and fit yourself — we don't provide measuring, installation or fitting services. This guide supports your own DIY fitting. Pre-sales questions? Call 0114 463 0090.
The 6-step filling and masking method
- Test the surface first. Test tape adhesion on a small, hidden area first to ensure it does not lift paint or leave a sticky residue when removed from your frame or wall.
- Apply protective masking. Apply a strip of flexible PVC electrical tape or low-tack painter's tape exactly along the edge of the shutter frame to protect its factory finish.
- Fill the void. Inject the hybrid polymer adhesive deep into the void behind the frame to create a solid, stable base.
- Smooth and channel. Smooth the adhesive down flat with a wiping tool or a damp finger so it sits just below the front edge, leaving a small, neat channel.
- Remove the tape. Remove the masking tape while the adhesive is still workable to maintain a clean edge and prevent it from skinning over or binding to the tape.
- Final caulk finish. Once the solid base adhesive layer is entirely dry, apply a final, thin cosmetic layer of flexible decorators' caulk over the top. This fills the small remaining channel perfectly and creates a smooth, flush finish that is ready for matching wall paint without any sinking or cracking.
