How to seal gaps between rough-hewn sandstone walls?

[Ivy6]

 Hi, Bunnings folks,

I have an old house with rough-hewn sandstone walls that was renovated in the early 1980s with some skirting boards, fibro walls etc.

It gets very draughty and cold in winter and I want to see if sealing gaps between skirting boards etc will help, but am not sure what product to use, as the sandstone is uneven and some of the gaps get a bit wide - I’ve included photos for reference.

I’d appreciate any advice you could give.

Hi @Ivy6 

I would   most definatly use " No more gaps"  will fill all the  wall skirting gaps of  varing  gap sizes and it is super easy to  clean  up with a  wet  white  cloth ideally.   Naterally use a  chaulking gun and cut the nozzle at an 45 degree angle at about 6mm diameter hole size,  The  product will help  keep out creppy crawles too,

So any over flows onto the timber can be quickly and easily wiped off and smoothed to rough wall using your finger as it is not too messy.

Do your whole  house while your at  it.   The  no more gaps yellows a  bit with age so no need to paint it .  But it is  paintable.
