If you have thick areas of paint that are dry on top but move underneath when you touch it, I wouldn't consider it dry enough - just because it is more likely to get damaged.

What Amanda said - also if you are taking it to a framer they like it to be at least touch dry, and preferably quite firm, because it makes their job a lot harder if they have to #### around treating it like eggshells. You can put retouch varnish on when it is touch dry, to protect it temporarily for exhibiting.

How long you need to wait for it to dry right through depends on how thick the paint is and hte mediums you hhave used. Generally speaking, when it is touch dry give it a coat of retouch varnish. When it is dry right through you can varnish it properly. My paint isn't terribly thick and normally I probably wait no longer than a month to varnish mine (perhaps a bit longer if I have used glaze mediumsm or if I have used a slow drying medium like the langridge safe gel). I have never had any problems with this approach. With time demands of exhibitions and getting work to galleries don't think there are too mamy professional artists who actually wait 6 months to varnish work.

I was really suprised to be recently informed that the Impressionists didn't varnish their work. At the current Monet exhibition at NSW art Gallery, all the work was under glass, but on closer inspection the work looked very thirsty. Anyhow, I found this a curious piece of information.

I think I remember reading somewhere that the paint they used was often pretty crappy, and some of them weren't too worried about the finer points of technique, with the result that many of their paintings are in much worse shape than much older works. I know van Gogh used some colours that have changed colour since he put them on the canvas.

Allison- wrote: How long does a painting have to dry before it's considered dry enough for a art competition ? i know it's probably been asked a million times.. I don't varnish my paintings but my husband does, and he uses a product called Gamvar made by Gamblin. If it feels dry to the touch you can use it. Some kind of special varnish formula that's removed easily.

Hi Rabbit, I have read all 25 pages of this thread (and compiled a word doc of the advice given by the Rabbit and others). I have one question for when you return. You mentioned using Retouch Varnish as a temporary varnish and removing it later and applying a varnish when sufficient time has passed. My questions are: 1. How do you remove the Retouch Varnish layer? 2. What brand of Retouch Varnish do you recommend? Thanks for all the advice given here. Great for a student to learn from! Carol

Carol Gee...all 25 pages and no brain freeze? lol The rabbit has been naughty, so I'll answer this........ You varnish right over the retouch varnish.....retouch varnish is a very light varnish, basically to bring you colours to life again & to rework your painting.....it's also used as a temporary varnish, until you apply the final varnish I use......and the rabbit also uses Langridge retouch varnish......a very famous artist told me to try the Winsor & Newton retouch varnish, so I bought a bottle to give it a go....i haven't used it yet. I like to add 10% Langridge distilled gum turpentine to the retouch varnish to make it a thinner coat and using a flat wide hogs bristle brush ( one that's suitable for varnishing )_I give the painting a thin even coat of retouch varnish When it comes to the final varnish I use a mixture of Winsor & Newton Gloss & Matt varnish, so as to get a low sheen. Basically varnishing is the same....1 thin, even coat. You can add 5% turps, as in Langridge distilled gum turps or pure turps to make the varnish flow easier. Have the canvas on it's back, face up & in a dust free place. Varnish from one end of the painting to the other, working the varnish with the brush to make sure the coat is as even as possible..... you need to work quickly as the varnish starts to set in a matter of minutes. Try not to go back and touch up missed bits, keep checking as you go, so as not to miss anything....but if there are a few try to get to them as soon as possible, so as to keep the varnish even.

I thought you were the Rabbit! Yes 25 pages, but got it down to 15 in word Thank you for answering. I've been looking at all the paints, varnishes, mediums etc suggested here. I'll have to win lotto or something before I can afford them. Might be a waste of money though considering I'm a beginner. It's wonderful that people are sharing their knowledge though. I just ordered some whiting powder over the net. A girl in one of my classes mixed it with water and a touch of acrylic paint to tint it. Then she used a palette knife to put it on a canvas, sanded it and reapplied. It made a very nice base for her painting. I'm going to experiment with it when I get my delivery. Has anyone played with whiting powder before? I believe its calcium carbonate and the same stuff they use to paint lines for football ovals etc. regards Carol

Has anyone played with whiting powder before?

OK....so someone in your class got some whiting, added water? to it & a touch of acrylic paint to make a ground that can be sanded & painted on? ......how can I put this? Does the blind leading the blind sound appealing to you? For starters it's not much of a ground to paint over, probably going to crack because there isn't enough "flexible medium" to hold the inert whiting as a gesso. She should've used an acrylic binder, not water.......it's like making making a house with mortar made from sand & water and no cement Anyway, a whiting based gesso is best made with ....dare I say it.... rabbit skin glue... & whiting....and even then it should be on a solid support, not canvas. Here's an archival way of using whiting & rabbit skin glue to make panels to use for oil painting. From my blog .... http://jimthalassoudis.blogspot.com/2008/01/new-exhibition-dates-for-my-melbourne.html Also, this isn't for the beginner ....the surface is difficult to paint on and absorbent. PS you ordered whiting over the net?...it should be in any good art shop....I found the best to be "Gilder's Whiting" from Langridge....it's superfine and comes in small packets because you don't need a lot. St Luke has it..... http://www.stlukeart.com/ PS....just a bit of advice....if you see someone in your class experimenting with "new stuff", chances are they have no idea what they are doing that also goes for most teachers ....pmsl The internetty is a good search for info....if that fails try the bunny

Thanks Jim, Thanks for the information about whiting. I shall put it away with a copy of your information on it. I did buy it from an online art store, I just don't recall seeing it in the art store I go to, not that I know everything they have. You'd be dumbstruck by the ridiculous stuff my current painting teacher wants me to do to my canvasses. I won't post it here because the walls have ears. I'm actually close to dropping out because of this. So how do you feel about multiple coats of gesso, sanded between coats, up to 6 - 8 layers. It basically gives you a smooth surface. Another teacher (filling in for my regular one) suggested that. Carol

Another teacher (filling in for my regular one) suggested that. Carol I assume you are talking about cotton canvas with 6-8 layers of acrylic gesso? If it's a reasonably good quality acrylic gesso, there is nothing wrong with that per say. It should be reasonably archival, but not if you add extra whiting. Think of gesso, or paint as pigment & medium....the medium is only there to hold the paint together......not enough medium, powdery paint or an inflexible paint film or canvas. Good acrylic gesso on cotton canvas should last at least a 100+ years, oil paintings on oil primed linen canvases have lasted 400+ years. PS Which art school are you going to, what are you studying and what year are you at......and of course what sort of paintings do you want to make?
