painting maple burned by saw blade

[stephen wood]

I ripped some maple for plywood edge treatment and wound up with burn marks. Next time I'll take more care. Anyway the plan is to paint the edge treatment. Do I need to sand off the burn or will some kind of primer (kilz, etc.) provide sufficient coverage?

[Bruce King]

Kilz is good stuff, sounds necessary unless you are using dark paint.

I would think shellac would be a good candidate as well.

Can a hand plane whisk off the burn?

[Gary Petersen]

Were you using a combination blade on your table saw? I've had recent issues when using a combination blade to rip maple. I believe I need to use a rip blade to clear out chips and dust better. I've sanded to remove the burn marks.

[Jim Becker]

My opinion and my practice whenever possible is to remove the burn marks, either via sanding or with a scraper and/or a hand plane. A stain blocking primer can certainly help but there's still no guarantee that the color will be consistent.

BIN shellac based primer ;-)

But its easy to remove them with a very light pass through the table saw or with a block plane. Don't use sandpaper.

I can use a plane as you suggest but just curious as to what’s the issue with sanding.

[Jim Becker]

A well tuned and very sharp plane will leave a smoother surface that doesn't generally need much sanding at all.
