I have a large walnut frame I have been trying to finish. The shelac finish keeps turning out poorly and I have tried rubbing it with alcohol to smooth it out. It has lots of streaks and and sags. I have tried diluting it with alcohol and using a foam brush, and getting a fresh can.

I am thinking I will just sand it down and use poly….any thoughts? I would appriciate the help.

try this, You will have to level what you have already, use a bit of oil for lubricant (I use olive oil) and wet sand with 400 grt.

Poly is #1 on my list when it comes to wood.

Shellac is no different than any other finishing choice. weather you are doing french polishing or spraying it, the best results are obtain when you sand between coats. The advantage of French polishing is that you can build the coats little by little and obtain almost a mirror finish, but you still have to sand at some point and even out the surface.

It sounds to me that you did not prepare your surface properly prior to using the shellac, or you have not diluted the shellac properly for the type of application you are using. If you spray a 1 pound coat is great, if you are french polishing a 2 pound cut is recommended, if your wood is too porous, then you might even try a 3 pound coat.

Don’t use a foam brush on shellac, and ya might wanna use a wiping varnish. Sounds like you’re laying on too heavy a coat of shellac. I have had good results from Modern Masters water-based urethane finish. It won’t “yellow”. I brush it on with a synthetic bristle brush (need a good quality here), then rub out with synthetic non woven pads, wax, and there ya go.
