I bought a Boler
two years ago from an unscrupulous fellow in Chetwynd BC. I failed to notice his fresh vinyl floor had been installed right over the rug.
This spring I thought to replace the flooring and found the wet rug sandwiched between a fibreglass “underlay” and the vinyl flooring. It certainly explained the elusive musty odour. It was consonant with his general maintenance ethic, however.
I have had to rip out the rug and the thin fibreglass “underlay” mat, leaving me with a plywood subfloor that has been coated with fibreglass resin. That surface is dotted with the resin and is uneven. When I have installed wood floors in houses, we have always ensured a very flat surface (after removing squeaks!) using a cementatious compound that could be leveled nicely, but it has no flex.
I am pondering doing a similar thing to prepare the subfloor surface for a fresh vinyl floor. I believe I would benefit from using a resin as it seems to retain some flexibility, necessary, certainly, on the roads where we take this Boler
I am concerned about getting a nice finish and would appreciate any thoughts or experiences anyone could share: brands, open times, effect of heat, recommended tools or trowels, all insights are welcome!
