I posted about some small punctures in my floating cork tiles
here, but now have a new problem. I can't find anyone who will agree to recoat this floor! The main sticking point is some slightly raised edges in a few areas where the tiles meet, likely caused by moisture infiltration. The "bump" or "ridge" is less than 1mm in depth, but the concern is that a screening machine will knock them down to bare cork, causing lighter lines. It's about a 5 year old floor, 525 sq ft., lots of walls/edges. The main areas in particular definitely need some protection before they get worse.
So... I've decided just to do it myself. The floor has lots of texture, which I hope will hide any imperfections. Having never recoated, I would be greatly indebted for advice you can offer on the following:
1. Should I rent a disc screening machine, or hand sand with a pole? What screen grit?
2. If either the machine or hand sanding does "knock down" the small ridges at tile joints to bare wood, is there a good method to blend them back in, e.g. use a furniture stain pen or rag with stain to mottle them?
3. What about the puncture and other small patches of bare cork: will the finish darken them, or should I pre-stain?
4. What is a good, forgiving urethane finish to use? Ideally locally available. Water or oil. The manufacturer suggests Traffic, but that might be over my head (and would have to be ordered), though I'm not averse to trying it.
5. How many coats (I'm thinking 2).
6. Most forgiving applicator? Roller? T-bar? Something else? Cut-in pad or bristle brush for edges? There are some pockets and slight divots, so I'm thinking a Roller might be preferred.
7. In a couple spots near the wall, gaps have opened up between the tiles (about a penny's width). I've heard of using suction cups to press them back together. Suggestions?
8. Anything I'm missing?
Thanks very much in advance for your help.
