Tight'N'Up Liquid Canvas Retensioner

Tight'N'Up Liquid Canvas Retensioner is the perfect solution to most canvas tension problems. It instantly and safely tightens well-stretched canvas and paintings that have slackened over time.

Simply spray a small amount of the solution onto the back of the piece. Once applied, Tight’N’Up soaks into the canvas threads and fibers causing them to swell and contract and the canvas to tighten. As the water evaporates, the binder agents remain in the fabric material, locking the fabric into a contracted state, restoring canvas tension, and leaving the surface flat and tight.

Not recommended for use on polyester-based or oil-primed canvas.
