How to make a painted wooden thing waterproof?
« on: January 18, 2010, 07:19:40 pm »
For some unknown reason, I painted my housemate's wooden knife block on a whim last night with some... acrylic? watercolour? I dunno paint. Now I'm a bit worried that it will get destroyed when it comes into contact with basically anything. I've never actually painted anything before and have no clue how to protect this. Any ideas? Preferably cheap ones?

This is the painting by the way:

Varnish.

Quote from: wikipedia
Varnish is a transparent, hard, protective finish or film primarily used in wood finishing but also for other materials. Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent. Varnish finishes are usually glossy but may be designed to produce satin or semi-gloss sheens by the addition of "flatting" agents. Varnish has little or no color, is transparent, and has no added pigment, as opposed to paints or wood stains, which contain pigment and generally range from opaque to translucent.

Varnish is probably right. But I want to shout random wood finishing products too!

Epoxy!

Moisturizer!

Primer is what you put on before you paint it.

Varnish is what you'll want. It can also go by "lacquer" (the difference is that varnish is painted on, lacquer is sprayed on). Ask in the store for a waterproof, polyurethane product; I don't know where you are and I really have no idea about product names outside of my own little workshop. Besides, I use acrylic varnish, and it's hardly what you're after.

edit: ooh, also ask how much it'll affect colour, obviously.

Yep, I just went with the first name that sounded right. I always thought Primer was it, but Varnish is it.
