I've rarely used waterbased poly before, but wanted to use up a can of Varathane Diamond polyurethane that I bought a while ago. I find that even though I gently stir it and take care to lay it on as smoothly as I can and not work it too much that I get a gazillion tiny tiny bubbles all over the surface. I remember this was what happened when I used it the first time as well. I do tip-off the work right after laying the finish on, and it helps a little but then it seems the bubbles re-form. I'm wondering if I can thin it with water to increase flow-out? I know I can just try it but I figure someone here must have tried it already. There's no mention on the can of thinning this finish.
