fill gap behind the skirting board

Question

I have taken out the old skirting board, and I have found loose plaster and a big gap, and I can see the brick in some places. How do I fill the gap to be ready to fit a new skirting board? What sort of material to be used, and need to apply any sort of PVA before filling the gap? Is it going to be flush to the wall plaster or leave a gap for glue/nail? Will it be done before the flooring is done?

Hi

If your looking for a quick and cheap solution then I would suggest using general purpose foam and spraying that in the effected areas. And then once dry shave back the expanding foam apply grab bond adhesive to the skirting.

The higher cost would be to filler the area will either plaster or plasterboard depending on the severity of the hole

Remov the skirting where is the gaps.
Make sure the wood are straight 
Some of them bending don't use it. 
After you check ✔️  frist complete your flooring tails or laminate then start you skirting. You need nail guns  start from one side then slowly push and nail them every 50cm Some times  very small gaps appear on the top don't worry . You use caulking filler to close it then paint it .

Hi best to remove all loose plaster behind skirting boards.  Then seal with either PVA or better SBR.
Then for a quick drying finish plus can dub out deep areas. Using Gypsum carlite bonding.  Then depending on new skirting back on. Then top coat with Gypsum multi finish plaster.

Remove all loose plaster first and brush/vacuum the area clean. For a deep gap back to the brick, use bonding plaster or a suitable repair mortar in layers, depending on the wall condition. A diluted PVA or bonding primer can be applied first if the background is very dusty or porous. Bring the repair roughly flush with the existing plaster so the new skirting sits flat. Once dry, the skirting can be fixed with grab adhesive and nails if required.

Hi
This is a common problem. For deep long spanning gaps it's best to use hardwall. Prep the area by removing all lose bits of plaster and clean the area well with a hard brush. Vacuum all debris and clean all dust from the area. A damp wipe down normally gets all the dust. Prep the area with PVA bond mix it 50/50 with water let it dry, repeat and when it goes tacky apply the hardwall, filling all the gaps. Allow the hardwall to start to cure then trowel it flush. It will shrink a touch as it dries. If you want a smooth finish apply a light skim of toupret filler one trowel flat. Do this after the hardwall has dried for 18-24 hours. Let this all cure for a further 2- 48 hours before attaching new skirting.

Hoover any loose dust, then water down 50/50 PVA and water, then mix a plaster product called Gypsum bonding coat, flatten off, let dry, 24-48hours, then skirting can be refitted with adhesive and secondary fixings, ie, nails or screws.
