Finishing surfaces that won't show?
Context:Plywood built-in bookcases.
I assume I should seal all surfaces in some way, even though the top, bottom, back and one side will never be seen. True? If so, what should I use? If it simply doesn't matter, I'll probably try to use up some cans of whatever is on hand. |

My experience is limited and I don't think I've used shellac since the jewelry box I made in the 7th grade. (seriously, 1970) It's hard to remember, and things may have changed. So tell me why I should buy some for the unseen areas, other than to have yet another thing to finish test pieces with. |

Well that was my guess when I asked for suggestions in the first place, but I'm asking now why shellac is a good choice as opposed to something else. |

They work well for slathering on shellac. (Pick off the bristles that shed). Cut the dewaxed shellac to 1# with denatured alcohol and apply liberally. Apply several coats and wait 3-4 weeks before rubbing out as needed. I'm no finishing genius but it works for me. Have fun. Lew |

If it simply doesn't matter, I'll probably try to use up some cans of whatever is on hand. FYI, no profesional cabinet shop is finishing unseen faces. Ply won't warp like solid wood. Really not necessary unless you have some extreme condition backed against a slurry wall or some other severe moisture situation. |

Because it seals against moisture vapor better than anything else, although poly comes close. But shellac wipes on with a rag and dries almost instantly. Pick up a can of Zinsser SealCoat and give it a try. Read the fine print - it says it's a 2 pound cut of dewaxed shellac. Get it somewhere with a good turnover - old cans don't dry well if they're over 2 years old. -- When fascism comes to America, it will be wrapped in the flag and carrying a cross. |
