I have used it for making 3D sculptures,.I think here in the UK we call it ModRoc. Using it on a canvas should be fine I would have thought. It might dry a bit gritty and bits might pull away after you have fixed it to the canvas and it has dried. The bandages usually dry rock hard and they would be fixed to a flexible canvas, so there might be some play, but I can't imagine it would come off completely. Be prepared for lots of mess, but it is fun.
thanks i can test it out. It occurred to me to give it a try as I have scraps left over after plastering fractures etc. The more i use it the more i get to know its properties - just afraid it might all fall off. cheers
Yes, I did. Here's the link to a video I made: http://www.youtube.com/watch?v=mK4S6JactwY I think it went just fine and it was a lot of fun and the kids loved it! That was over a year ago and it has held up wonderfully.
I've used it a few times. It's really easy and fun. It also binds really well with the canvas and I've not had any problem with it flaking off. You can make it smooth or leave some of the texture showing and acrylic paint loves it. I have a couple of pics of pieces I did in Gary's class using it. Look on my page at the pics labeled egg I and egg II, I've used it for the background leaving some areas smooth and some textured. Have fun with it.
The stuff I have is wet thoroughly and globbed onto the canvas - no prep required. It is impregnated bandages with plaster of paris. You get a little time to smush around and maybe drag a tool or a comb through for some neat lines but then it starts to harden - just like the casts on an arm/leg ....rock solid...
So once i have my image printed onto transparency film, I take my Ezscreen silk screen which has been coated in light sensitive emulsion (These sheets come pre-coated so they are ready to use). Place it onto a black board, then place the transparency image on top (this part needs to be done in a dark room with no direct sunlight). I take it outside and expose it for 1 minute and 40 seconds (but time varies depending on time of day and strength of sunlight). After i have exposed the image i place it into a tub of water for around 5 - 8 minutes. Then i rinse the screen out under fast running water until the unexposed area (the black) washes away. I then expose the screen to the sun for a further 20mins to completely harden the light sensitive emulsion.
And this is the completed screen ready for printing. I simply use an old credit card to spread the ink over the screen making sure i do one complete full stroke across the screen (holding the credit card at a 45 degree angle). I immediately wash the screen out under fast flowing water and pat dry. I use fabric screen printing ink which washes out in water (which makes the process easy).
