I have mistakenly applied water-based latex primer on my particle
board book case that I am building. Now the areas where I have
applied water-based latex primer have raised grain excessively. I
have tried sanding the raised grain. But I can only sand away the
high spots, and I cannot sand enough to remove the low spots (primer
keeps clogging the sand paper doesn't help either).
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.
