Masterpiece Tight'n'Up Canvas Re-Tensioner

Patented technology that tightens-up loose canvases

Masterpiece Tight'n'Up™ Liquid Canvas Retensioner solves most of the problems associated with loose canvas, ripples, wrinkles, bubbles, sags, etc. It will not harm the canvas, priming, or the picture. The secret acrylic polymer formula is acid-free and archival. The water in Tight'n'Up™ makes the canvas threads to expand, shrinking their length, naturally tightening the canvas. Acrylic binders in the spray trickle between the canvas fibers, and give extra support to the canvas. When the water evaporates, the acrylic remains in the fabric and prevents the material from relaxing to its loosened state, thereby maintaining the increased tension. Tight'n'Up™ may be applied to the entire back surface of the canvas, but it is best for problem areas.
