White solid paint finishing onto wooden furniture is having problem with the defect, the gum resin from wood or bleeding are coming out to the surface, making a flack and stain on it.
what system and materials for doing the white painting is best one?
any experience on it to share? I love to know that.

woods with gum/resin should NOT be painted with ANY color without first putting down a coat or two of knot sealer

In the US we have a product called BIN from the Zinsser company. I don't know if it is available in Indonesia but the main ingedient is shellac. :smile:

Wipe the surface with acetone. Apply several coats of fresh dewaxed shellac. Or, use a two part epoxy as a sealer.

if it's going white, try not to use any timber with knots, even with a knot sealer there's a good chance the knot will bleed and either cause cracking/flaking or at the very least cause a discoloration.
