Modeling Paste

I am not a painter, and don't know squat about it, but something I always do when looking into new 'stuff", is to go to the website and read the reviews. Here's one from the Liquitex site (and most of them talked about cracking):

Comments about Liquitex Modeling Pastes:
"I've used Golden and Liquitex modeling paste since they came on the market. Liquitex versions dry faster than Golden and are not as flexible when totally dry, they are more like drywall mud and less plastic. However, this has it's uses and sometimes it is a better paste for that reason. It does crack a bit when used over 1/8 inch thick and it is better for solid supports rather than canvas. A bit more crumbly than Golden's version, be more careful when carving or sanding. Also, use a mask when sanding, the dust is toxic."

For stretched canvas you need to use "Flexible Modeling Paste" The version in your photo is for rigid supports only, it will crack on stretched canvas.

Sharu,
If you've already bought the paste... maybe it's time to experiment with painting on rigid surfaces...

I think you will find Gel Medium a better fit for your work than the Modeling Paste. It's mixed into the paint and made for impasto techniques.

Thank you dear friends for your helpful replies. Yes since I am working on stretched canvas I think I ll exch.ange this one for the 'Flexible'modeling paste...so it does not crack. Thanks once again...Cheers
