polyurethane on raw plywood

[gychang]

I am building a speaker and plan to put on the the miniwax "Wipe-on Poly" without any stain. Do I still need to use the preconditioner?

thanks,

What kind of plywood are you using?

It would depend on what type of plywood you are using. Is it a secret?

What kind of plywood are you using?

I am using 3/4" baltic birch plywood.

thanks,

The conditioner is intended for soft woods and to control streaking and blotching. You don't really need it for Birch. The Minwax Wipe On, is basically an oil base poly that has been thinned with MS. You can put almost any clear finish on BB. Some finishes to me look better when their natural characteristics are evident.

A general tip for finishing, is to do samples. start to finish with each step noted, so that when you've tried your variables, you can see what you like best, and look on the back and see exactly what you did and what quantities of what were used.

Try a sample both ways, and see if there is much of a difference.

No preconditioner needed.
