by your reply i would assume no problem. i know that if you use anything with a wax base like shellac, poly will not dry

No, you won’t. I’ve used a lot of it and have not had the slightest problem

I use it with no problems. The fine stearates leave white
stuff in the pores, so it’s important to blow, vacuum and use
tack cloth… or at least that’s what I do. In terms of
an adverse affect on finish adhesion… none that I know of.

You’re not supposed to use stearated sandpaper when using water borne finishes. I’ve had no issues with norton’s 3x or 3m’s sandblaster with water bornes though.

I think with certain stearated paper and certain finishes you can have a problem. I think this happened to me once with a waterborne finish, Target Coating PSL ( the name has been changed a few times) and Klingspor paper. But I’ve used a lot of stearated paper on other stuff and never saw the same effect. The problem I had was adhesion, and only in certain spots. The finish came off in a very sharp edged spangled looking spot (several spots, actually). OTOH, I may have mis diagnosed the whole thing. But polyurethane resins do inhibit adhesion (that’s why you sand between coats) so I suspect there is a possibly….maybe just a remote one.

I learn something new on this site all the time.

Stearate Lubricant

Often made of a metallic soap, the stearate is a dry lubricant applied to the surface of the paper, filling in the space been the grains. The application of the stearate prolongs the life and use of the paper, preventing the sanded material from clogging the areas between grains.
