Masterpiece Tight'n'Up™ Liquid Canvas Retensioner

Masterpiece Tight'n'Up™ is a smart, studio-ready solution for fixing loose or sagging canvases. This patented formula helps eliminate wrinkles, ripples, bubbles, and sags without harming your canvas, priming, or finished artwork. The secret is a unique blend of acid-free, archival acrylic polymers that tighten the canvas naturally and help it stay that way.

When sprayed on the back of the canvas, the water content causes the fibers to expand and shrink in length, tightening the surface. As it dries, the acrylic binder remains in the weave to support and hold the tension. It can be used across the entire canvas or just on specific trouble spots—and it dries clear for a clean finish every time.
