Flooring – How to seal a 4+ mm gap between skirting board and slate tiles

flooringkitchens

I have a slate kitchen floor and wooden skirting on the walls around (no beading). At some points around the wall there are gaps of around 4 mm or more.

I was thinking of simply stuffing paper in the gap and then using polyfilla to cover the gap (sanding it off and then re-painting the skirting).

Does this sound like a good idea? I am worried about making a mess of the slate floor using polyfilla.

I would use foam backer rod in the gaps, put down masking tape on the slate (and perhaps above the joint, on the skirting and fill with the polyfila or perhaps a colour matched latex based caulk.

Pull the masking tape right after smoothing the joint down with a finger.
