I need to varnish over acrylic paints on wood and MDF. I think I have read that you should use acrylic varnish. Is this something you buy from an art/craft store? I want to make sure that it's going to dry clear and will not stain the wood.
Thanks

You can buy clear acrylic, but it's very expensive and hard to find.

Water-based (PVA) indoor varnish will work fine. The sort that looks white in the tin, and washes out with water. It dries sort of plasticky & completely clear, and works fine over acrylic paint.
You'll need a couple of coats, and you might need to rub it over with a fine abrasive between coats, as it might "raise the grain" - when that happens, the surface goes kinda rough, but a quick & gentle rub down after the first coat is dry will make the next coat go smooth.
I've done this lots of times... :)

Have to agree with Scorch. I use a well known large high street retailers own product. In fact I bought some today 3 odd for a small tin. I use this interior varnish on my full size acrylic paintings and it works fine. I happen to use the satin - which gives a very light semi-gloss finish - clear. Dries in no time.

I've just bought some spray acrylic lacer from Halfords (believe it or not!). Spray cans are about 6.99 - 8.99 ish depending on size.

I've not tried it yet but it might do the trick.

I do the same as Scorch and Somerset artist and have no trouble at all. I used a spray varnish on one of my paintings and it stank so much :o but the tinned, milky stuff that dries clear gives a really nice finish. I like the finish that satin gives but that is personal choice.

Remember to take your piccies before varnishing to reduce glare ;);)

Places like Halfords and other car places are great for bits and pieces for woodwork etc. Often cheaper as well. Haven't tried the PVA stuff. I'll have a go with that as I find acrylic paint on wood can be unstable and blend if you aren't careful. Thanks for the tip Scorch

Just be careful with your varnish as most varnishes not made specifically for artwork ie: canvas's etc, will yellow over a short period of time. ;) Although sometimes...I feel this can add to the charm of a piece!

I agree, clear acrylic interior varnish is the way to go.

I use the satin finish too.

Agree with above used to make papier mache pigs and used acrylic paint. Either PVA will do or I used to use matt varnish from B&Q. You don't need to buy over priced stuff from art shops, its the same thing.
