Reviews
Caulk Once 380ml is rated 4.3 out of 5 by 47.
Rated 5 out of 5 by from Best I've ever used Recommended by a professional, who gave me some to use on new sills in an extension. Since then I've refitted skirting and sills in another room and find this caulk is far better than cheaper ones. It doesn't discolour, is paintable very quickly and most usefully, doesn't shrink - at least after the first year, so far. Worth the extra cost I would say.

Rated 5 out of 5 by from Bit pricey but excellent Was bit dubious of buying at this price but gave it a go. Found it really easy to fill skirting gap and good finish. Seems fill gap. Well and has not cracked or fallen out like other caulks used. The tube is large and ended up wasting half of it. Wish did it in smaller size and cheaper cost but seems name is correct - caulk once and job done.

Rated 4 out of 5 by from Painters Caulk It's one of the best I've used, but still shrinks quite a bit when drying.

Rated 5 out of 5 by from Probably the best Caulk I've used. Bought this to fill some gaps between a ceiling beam and ceiling before painting it. Gaps were up to 15mm in places, this seems to have filled them nicely without shrinking so far.
