I imagine it's going to be very hard. If your off by just a little bit it would show badly. My idea is to proceed very slowly. get maybe 4 at a time done perfectly, let them set and than go for 4 more. Either that, or do a larger area, and lay a perfectly flat finished piece of plywood with weight oh top. As far as what to seal the surface with, I'm going to check into it more. I imagine that a good floor wax buffed onto the surface will seal it but i will check into it. Maybe some kind of polyurethane. I'm not going to start till I have found someone that has done this type of job. When I find out, I will come back and post.
