In the case of wax-resin adhesives, vacuum tables with temperature control functions are able to uniformly apply conditions of heat and pressure across the surface of an artwork, reducing the liability of damage in the hand-ironing process.

A prepared canvas was then attached to the back of the paint layer, using the same method as was used for lining pictures. When the glue had dried, the paper and muslin ...
