I’ve laid a fair bit of Karndean tiles and they’ve been very stable and long lasting. A couple of years ago I laid some LVT planks in our small bathroom, used 9mm WBP ply with F-Ball primer and Karndean pressure sensitive adhesive as I always have. The planks were in the room for at least a week prior to laying. After a few months, the planks started to have a small gap between the ends <1mm. I’m about to lay the same planks in our new kitchen (probably in a herringbone pattern) and am worried that I’ll get the same gaps and it’ll spoil the job. Is there something I’m doing wrong in my method, or something I should to to minimise any gaps. I have seen a few others mention these gaps (shrinkage I guess) in Karndean, so wonder if it’s a product issue..? Any advice very welcome.
No, it’s a bathroom with no windows, no UFH and the floor space is only 2m x 1.5m. The building is 1850s and very stable and settled.
I was reading that the Karndean adhesives weren’t brilliant and to use something like F Ball F44, does that sound right..?
