How to Fill a Large Crack in a Wall in new Build Property

Postby earlydoors153 » Sun Jan 21, 2018 12:47 pm

Hi - I moved into a new build a couple of years back

Since then these large cracks have been appearing. I want to fill them in and have tried to use the Polyfilla Deep Gap - however the crack is so large that I can't seem to get a layer thick enough to sit in the crack. When it dries, it just sinks through and falls into the storage space underneath.

Any ideas how i can fill this up? Should I use a different product? Or a different technique?

Appreciate your help
