A note of caution for anyone repainting their cabinets
I have similar cabinets to girlwithaspirin and have run into problems with the paint sticking. I cleaned my doors with TSP, sanded, recleaned to remove the dust. I then painted 2 test doors. On one door i put a coat of 123 primer first and then the first coat of Impervo. On the other door i skipped the primer and painted just a light coat of Impervo a la girlwithaspirin's directions. I then let both dry for 24 hours.
Unfortunately, the paint scratches off both doors quite easily -- the door without primer easier then the door with primer. I am certain that allowing the paint to cure would have made little difference. You can tell within 24 hours if the paint is going to hold or not.
I'm therefore glad I did the test first. I doubt it would have been very long before the doors looked awful through regular use.
Obviously whatever finishing/protection coat (not sure whether it is urathane or something else) is preventing the doors from accepting new paint and I will have to strip them further.
I will keep you posted on my progress. Oh yeah, and if anyone has been through the same problem and has any tips I would love to hear them. Tks!
