Hi,
If your wooden furniture has a lacquer or varnish based finishing, you may use sandpaper to remove the finishing and redecorated with either clear or coloured varnish, shellac or wood stain instead of the Nippon Bodelac or ICI Gloss Finish (enamel paint).
In our local market, Nippon Paint offers Timberlac (wood varnish) that comes in 7 shades in glossy or matt finishing.
ICI Dulux offers Timbertone that comes is 5 colour tint.
Kangaroo Paint on the other hand offers a highly durable, PU (polyurethane) - re-inforced stained (coloured) varnish. It also has another range of solvent based wood stain under Kimber-) range.
Another more exotic brand Wood Kote from USA offers a unique gel based wood stain that has over 30 colour tones to choose from.
For additional protection and a more durable coating, you may apply a clear PU (i.e. Polyurethane)finishing that provides more than twice the protection of normal lacquer based finishing and PU coating will not yellow with time.
Currently, I've only come across the Rustoleum brand in Singapore.
You can visit www.estore.com.sg for all the products that have been mentioned. They have quite a comprehensive range.
Hope this info helps and happy DIYing
