I am building a table out of red oak. After I sanded it smooth, I stained it with minwax dark walnut (oil based) by using a stain sponge. I would wipe on the stain let it sit for 10 minutes and then I would wipe it off. I repeated that 2 times. It started seeping back up to the surface. I gave it 48 hours (wiping off the excess periodically) and after the 48 hours it stopped. I started to apply polycrylic finish and so far after 5 coats spots of the long grain is still rather bumpy and looks like tiny bubbles surfaced (some look like the pop i cant tell they are so small) and dry causing just the long grain to be rough. This doesn't occur anywhere else but on the long dark grain parts. Do I keep sanding and applying top coats until I have a smooth finish? Will this ever stop?
UPDATE - After doing some research I moved my table indoors where it is warmer (garage temp is around 45 degrees) to help it dry. Now I am seeing "bleed back" or stain seeping back to the surface again through the clear coat!! What do I do?
