Post by: Dustyknees on February 20, 2011, 09:43:06 pm
Hi All.. I saw a post awhile back that gave advice on how to stop stains from making blotchy areas on wood. Can someone point me to it?..Thanks..Jon

Not sure where you saw that info but, it should be somewhere in this thread.
Anyway, the best way to stop wood from blotching when staining is to coat it with shellac first. The way I do it is use a one pound cut of shellac, let it dry, lightly sand it with a very fine grit of sand paper (220 grit or higher) to knock down the fuzzies then stain and finish to suit your self.
The shellac you buy in the quart cans in the store is a 2# cut. In order to get a 1# cut is to mix some shellac with an equal amount of denatured alcohol and brush it on. (I use a foam brush usually)
It drys fairly fast, depending on the temp. and humidity, usually 15 minutes or so and fills the pores of the wood so it doesn't soak up the stain in different areas of the wood more than other areas.
Hope that helps.

Roger is correct I'll just add I sand the end grain to one grit higher than the long grain. So if I do the long grain to 220 I'll go to 240 or even 320 on the end grain.
