Hi all,
In the past I have used decorator's caulk to fill in gaps up to around 5mm, and that is not a problem.
I have also put aluminium mesh behind plasterboards then used polyfilla to fill big holes, and that is not a problem either.
But the problem is now I have some gaps that are around 20-30mm wide. I can't use decorator's caulk because it has nowhere to bond - I tried building layers of it up daily but it will take ages and the finish isn't remotely great. I can't use polyfilla either because there is nothing it can grip on, and that there is not enough space to put mesh behind.
So what is the best way to fill these gaps in please? Bear in mind I am only a DIYer, and I cannot do proper plastering.
Thanks.
