Topic tags/keywords: question finishing

I’ve built a play kitchen out of Baltic Birch and plan to finish it with 3 coats of polyacrylic water based top coat. To minimize visual hardware, it will be assembled with glue and biscuits. Because of all the detailing and nooks and crannies in the play kitchen, I’d like to apply the clear coat before glue-up since I can do a better job with sanding between coats. However, will I compromise the strength of the glue joint if I apply the finish first? Thanks for any feedback!

Most glues will only stick to to plain wood. So either keep the glue away from any joints or finish after assembly.

I agree with jerrymayfield above. I finish before assembly when possible and use blue painters tape to mask off the areas to be glued.

use blue tape to cover the area where the joints will be. then finish the piece.

take the blue tape off prior to assembly,and you should have wood-wood contact for the glue.

Use the tape before you glue even if you don’t do a finish first if you are going to clear coat your work. The glue on surfaces to be finished is a buger to get off.
