First cabinet project... very little selection in my area. Cabinets will not be visible on outside (walls on 3 sides next to fireplace)... only inside surface visible. I am debating whether to use unfinished birch or some prefinished material. For unfinished, I have A1 Birch at a couple lumber yards and C3 birch at a couple other lumber yards and also at HD and Lowes. My only source of prefinished is special order from one lumber yard, and they only have birch in 3/4 C2 2-sides and 1/4 B4 1-side... so my cabinet back would be B grade and sides C grade... they don't have 3/4 in B or 1/4 in C... strange.
I guess my main question is... for interior of cabinets, is C grade plenty, or do I want B grade? Seems like paying for A is a waste of money.
If the answer is that C is fine, then is it worth the cost to use prefinished and special order, or should I just go to HD and grab 3/4 unfinished and a spray can of poly for the interior?
I'd appreciate any feedback.
