Is there anything that can be dispensed (ie from a sealant gun/spray foam( that would support weight where the worn area is rather than using the packing I’ve used so far?
For it’s purpose (carpeting) what I’m doing will probably be fine but when screwed down the 12mm ply isn’t lying quite as level as I’d like.
Just wondering about any ideas for filling the gap the worn stair treads are leaving. Considering smoothing with some sand/cement but im not sure how ideal that really is either. Bit messy and might still break up..
thanks
