Yes, I should have used oil based primer. I have applied oil base primer in one small area of the book case, and it turns out very nice after I have sanded the area. But this is too late now because I have already used the water based primer on most of the book case. I cannot turn back the clock, I need to find a way to "fix" the problem.
I can try aggressively sanding the surface. But I am afraid that the sandpaper will keep clogging. And the heat that will generate from aggressive sanding may not be good for the primer.
I can paint several more coats of latex primer, and hope this I will fill up the low spots. But I am afraid that this is just wishful thinking. The primer may simply follow the ups and downs of the surface, and I may just waste my time.
I can use chemical to remove the primer, and do this over again. But I am afraid that the chemical may raise the grain even more.
The only way that I can think of is to use a scrapper to manually remove the primer, sand out the raise grain, and re-prime with oil based primer. But I think this will be the last resolve.
Is there a better way to deal with this problem?
Thanks in advance.
