Water based varnish

[dantontod]

Hi -

I'm currently refinishing this teak (veneer) cabinet. I've decided to use a water based varnish. I brush it on and then use a good quality roller to get a nice even finish.

It's going on great, the product is nice and level, no orange peeling/unevenness etc. The only thing I've noticed is there are some lighter areas (almost white) - picture attached.

Why would this be? Is this just the nature of teak veneer? Did I not remove previous finish adequately?

Any pointers happily received

I stripped the unit with a scraper and then sandee with 180 grit (electric sander), wiping down with methylated spirits afterwards.

Hi I've used water based marine varnish on many occasions what you've described sounds like to much applied in one area as I've had the same problem on several occasions. My advice is let dry sand back and repaint. Or possibly reacting to oil residues left in the wood.
