Hiya, please see the attached pics. The floor is of original pine floorboards that were restored, sanded and sealed by something (likely to be varnished) by the previous owners some 7 years ago. It is still in pretty good shape and should not need resanding-revarnish for a few more years. But the sealant in the gaps between the floorboards is coming out in places. These new holes/gaps are drafty and I want to seal them. What should I use? Most of them are quite narrow (less than 5 mm). Cheers
This is the fella; https://osmouk.com/product/gap-sealer/ Comes in a pile of colours. Light oak is the closest match for stripped floorboards.
It will indeed. It’s acrylic so it sticks to anything and stays flexible so it stays put even when the floor expands and contracts. Very good product.
Thanks for that info. I'll soon be sanding a floor which I'll be finishing with Osmo this stuff will help.
