What are the curing instructions for Martha glass and craft paint?
Paint is permanent after air drying for 21 days or can be baked to expedite permanence.
Bake-to-Cure Method: Make sure the paint is dry to the touch before baking. Remember also to put the project into a cool oven before turning on the heat. This will allow the paint to increase in temperature gradually. If there is some moisture still in the paint film, the rising temperature will drive out the moisture before curing starts. If there is moisture in the film and the project is placed into a pre-heated oven, the temperature of the paint film will rise quickly and start curing too soon, which can trap moisture and cause the paint to bubble as moisture tries to escape.
Please note: Fine Glitter Glass Paint, Glitter Craft Paint and Coarse Glitter Craft Paint cannot be baked and must air dry for 21 days for permanence.
