Getting really fucked off with this!!!!!!!, by jed100375 on Jul 21, 2008 22:44:56 GMT 1, Hi,
The problem i'm having is that my paint is cracking. the picture below was done at least a month ago and although the final result was good a month later cracks started to appear! The black background on this picture was a little patchy and a very thin coat.
Before the canvas above started to crack i thought i would try completely covering another one to get a smooth finish. It was perfect....for three days then this happed....
As you can see its completely fucked!!
I thought the resolution was to do one really thin coat let it dry then another and another and another....at the moment its perfect....
So my question is do i throw all this paint away? Its german montana..... before anyone says it i read the really interesting post about paint from about a month ago and although very informative it did not tell me about this specific problem. Even on the second and third photos above (this was and extremely thin coat its still fucking cracking!!)
As its only the background colour that seems to be cracking i concerned about wasting my time painting the actual picture if it gonna be ruined by the background. The black i am using is 'shock black'
Please please please please help especially since i have spent this much on paint!!....

Getting really fucked off with this!!!!!!!, by Photoxtc on Jul 21, 2008 23:17:48 GMT 1, are you giving the paint enough time to cure/dry before applying more coats (this will cause cracking if not fully cured)... I would also try using an oil based primer on the canvas... you may just need to experiment a bit

Not being primed was my initial thought as well. When you say quality....what kind of quality? Is it a cotton canvas or linen? And did they come primed or did you do it yourself?
The reason I ask is because cotton canvas is cheap and is less stable. Also, cheap canvas is less likely to be 'sized' which can affect the absorption of the paint which could lead to cracking.
Another thing is the room temperature can affect the it. If it's too warm the paint can dry too quickly and crack.

Getting really fucked off with this!!!!!!!, by Dellboyy on Jul 21, 2008 23:20:19 GMT 1, I've only tried covering a canvas completely in black once, and it turned out fine... i was using black belton paint and didn't particularly try to keep the layers thin. I've just had a quick look and it's still very much un-cracked... there might be a chance this is something to do with the german montana paint you're using, but i really don't know enough to say having not used that stuff much!
All i can say is, on my double primed canvas, a couple of layers of roughly sprayed black montana paint still hasn't cracked!

Getting really fucked off with this!!!!!!!, by ihate69 on Jul 21, 2008 23:34:58 GMT 1, hi..
in my experience its all about what you have used t prime the canvas
you need to prime it with the correct primer that you can buy from the place you brought the canvas.
this needs to be applied in thin layers and built up slowly once this is truly dry then apply the spray paint.
as whats happening is that the spray is reacting with the paint you have used for the priming of the canvas this can range from what you have to many other effects. i use to use many things from actually spray paint to prime to it household emulsion learnt in the end
so get some proper canvas primer stretch ya canvas first and layer it two or three coats and leave it a while to dry.
not used montana really as im old school.... / buntlack and belton when i was painting.
these never caused any problems
ps if this dont work why dont u use the paint on a wall instead.
thats kinda what i would do with all that paint

Getting really fucked off with this!!!!!!!, by Ripper1331 on Jul 22, 2008 3:32:03 GMT 1, If the canvas comes primed there is no need to prime it period.
If it's cracking it's could be a couple of things:
Too much paint going on before the last layer was dry
The paint is drying too fast so if it's really hot or youo are leaving the canvas to dry in the sunlight this will cause problems.
Mixing and matching paint - not all brands work together and even if it is the same brand gloss, semi-gloss and matt paints dry at different rates so if you are mixing finishes this can cause cracking. You should steer clear of mixing brands of paint without doing some tests first.
Hope that helps.

Getting really fucked off with this!!!!!!!, by daley on Jul 22, 2008 9:55:40 GMT 1, Shame to see your artwork cracked like that mate.
The general rule with oil and water based paints is that you can put oil over water but NEVER the other way around - as the oil based paint takes much longer to dry and will crack the surface of the fast drying top layer.
Maybe some of the paints you use differ in this way.?
It could be the primer also. As you know there's various primers - gesso, rabbit skin glue, lead white primer, acrylic based, oil based primer etc. I guess if your canvas' are primed with lead white or oil based then the quick drying spraycan on top will crack in the long run. Some primers are ONLY made for oil paints to go on top see.
If your using spraycans I personally would only recommend water based gesso or acrylic primers as they dry faster.
Varnishes can cause cracks too, especially if the layers underneath are not completely dry.
Hope this helps.

How do you spray your backgrounds?

Getting really fucked off with this!!!!!!!, by instinct on Jul 22, 2008 10:10:16 GMT 1, One of the things that you might want to investigate is that you are applying too much paint too fast. Try more layers with less coverage and longer intervals between coats.
Also I have found that cold and slightly damp conditions will almost always result in cracking. Try to ensure that the canvas is kept in a dry room (not a garrage) and at room temperature.
As for accepting cracked canvases... I have always knocked them back which has not always been comfortable, but hey as a paying customer i want the best.
