The Little Big Gap Box – Single Room Deep Fill System
Sometimes you don't have a whole house to fix, just one annoying gap that refuses to stay filled. Maybe it's a drafty window frame in the spare room or a single section of skirting that has pulled away from the wall.
The Little Big Gap Box Kit is the specific fix for those deep, stubborn gaps in smaller spaces. Standard filler on its own often splits in wide gaps or simply takes forever to fill because there is nothing behind it to hold it up. That's why we included the backing rod.
This kit gives you 5 metres of closed-cell foam to pack into the void first. It creates a solid foundation so your filler sits flush and stays there.
We’ve paired it with our compact sizes of Prep-It and Smooth-It, plus two tubes of filler, so you have exactly enough to bridge the gap and get a seamless finish without buying more than you need.
The Kit Includes:
-
250ml Prep-It Surface Cleaner
-
250ml Smooth-It Lubricant
-
Applicators for a sharp finish
-
1 x Tube of Paintable Polyurethane Gap Filler
-
Paper Towels
- Easy to follow instructions
