I have a gap behind my skirting boards and though I would glue these in intervals and then glue the skirting boards to these. Perhaps pop a few screws into the skirting and wall too.
I am using the pink gripfill for these and I think because the surface is dusty, it’s not sticking. What do you recommend please?
Thanks in advance
