Fixing skirting board to less than perfect walls

[shd1970]

I’m in the process of fitting some new skirting boards
Unfortunately, removing the old ones took away an amount of the plaster leaving me with some holes (see photo)

I’ve made good with some Soudal expanding foam and levelled it off so that the skirting board sits flush
However, I’m obviously not going to be able to screw and plug consistently across the length so I’m looking for some advice as to what adhesive to use in addition

Will Gripfill adhere MDF to expanding foam or is there something else I should use to supplement the screws and plugs ?

Thanks in advance for any guidance

Use foam to stick skirting on

As above, you can either use low-ex foam or a grippy polymer adhesive such as Stixall, CT1, Sticks Like, Fix All etc.

@Wayners @noseall

Thanks both for the replies

So not gripfill then ?

No. Especially if you are using pre-primed MDF. Unless they have ditched that rubbish solvent cure stuff and produce a polymer type...?

If your wall is uneven then it will look much better if you don't follow every ripple. Aim to just glue the whole thing, only use screws if there's a problem area where it's too far out.

It will look best if the skirting is straight. Then caulk the uneven gap between it and the wavy wall.

Thanks again for your reply

This skirting board is simply from B&Q
Here is a photo of the front and back :



As you can see, the front is primed whereas the back less so, so I’m not sure as to which out of your suggested products would be best

Would you lean towards the low expanding foam or would you plump for one of the adhesives you’ve listed @noseall ?

We always use polymer adhesives. Foam is too unpredictable, even the low-ex stuff.

…and it sticks well against expanding foam @noseall ?

Not the ideal substrate, but yes, it sticks to foam.

I once had a natural wood skirting cup slightly from using water-based glue, due to the water content making the back of the wood expand. It should hopefully shrink again after it's dried though. I've always used solvent based since as a precaution. Expanding foam is horribly messy, and may continue expanding and push it away from the wall after you've walked away.

Polymer adhesives are far superior, especially if there is any moisture present.

You can buy low-ex foam, specifically for sticking material together. It can be messy though.

Thanks @noseall @Ivor Windybottom

I’ll do a quick read up and check reviews on thePolymers suggested by noseall earlier in this thread and put a generous amount on

Thanks both for your inputs
