I recently completed building and installing an island cabinet and a pantry cabinet for a client. When I was done the client asked if I could price painting their existing cabinets. The existing cabinets are stained/clear finished oak and the grain, well it looks like clean finished oak. The client wants to paint the cabinets and not see the grain. I need a recommendation on a grain filler to use. I am going to take the doors and drawer fronts off and bring them to my shop to spray them. I may also bring my turbine and spray the boxes. I don't have time to try a bunch of different products right now.
From contributor J:
Other issues will come up, but, yes, you are right to worry about the grain when painting. It won't drop into the pores and they will look dark(er). Wash off the crud and the polishes (TSP, sodium sesquicarbonate) and then spackle fill the grain. Sand off the excess when toothing the old finish for your primer/bond/bridge (maybe BIN 123).
