We sealed our timber benchtop on the weekend with a Cabot's clear flooring polyurethane (was told that this was perfect for benchtops) and it has not turned out how we expected...
We sanded the timber smooth using a belt sander/by hand until it was perfectly smooth.
We then applied x 2 coats of the polyurethane in a matt finish and it has dried with a rough 'raw timber' feel to it! We applied it with a gloss roller brush and brush (as per instructions).
It looks perfect - no streaks or imperfections. It is also water resistant.
I'm wondering if it is because we used a matt finish vs a gloss? Any suggestions?
Hey @KingStreetReno - the matte finish shouldn't have a 'raw timber' feel but it obviously won't feel as smooth as a gloss finish. I'd suggest going over the matte coat with a gloss coat if you'd prefer that smooth finish. You may have to sand the matte finish back before applying a gloss coat but I'm not 100% sure, hopefully someone on workshop has had some experience with it. The alternative is to call the manufacturer.
I would try lightly sanding the polyurethane that is on the benchtop currently, and apply a final coat with a brush, rather than the roller.
In my experience, I've found that flooring polyurethanes can bubble with a roller (and in your case with a matte finish, feel rough to touch.)
You could also try a flat head applicator, made from a sheepwool material.
