This new liquid canvas re-tensioning technology solves most all of the typical canvas tension problems. It removes or improves any previous sagging, wrinkles, or ripples in the canvas, leaving the canvas flat and tight. Tight’n’Up dries clear so it will not affect the look of the piece.

Simply brush or spray Tight’n’Up to the back of a painted or unpainted stretched canvas. The water in Tight’n’Up causes the canvas threads to swell up, thereby shrinking their length, consequently tightening the canvas. Acrylic binders in the Tight’n’Up seep in between the fabric’s threads and fibers, and provide extra support to the canvas. When the water evaporates, the acrylic remains in the fabric and prevents the fabric from relaxing to its previously loosened state, thereby retaining the increased tension. Tight’n’Up may be applied to the entire back surface of the canvas, but it is best applied only to the problem areas.

Tight’n’Up will not harm the canvas, oil or gesso priming, or typical artist paints. It is an archival quality and acid-free art material. It works best on cotton, linen, and other natural fiber canvases. Tight’n’Up is suitable for most any canvas tension problems.

	Masterpiece Tight'n Up Canvas Retensioner (5/5)	Feb 3, 2008	K. Chapman	Snohomish WA US
	I have used this splendid product for many years, whether I'm using oils or acrylics. It works best if you pour (rather than spray) a light coat on the BACK of primed canvas or linen, then scrub it in even under the corners of the stretcher bars. (You want the surface to appear wet.) Dries quickly and canvas will be a perfect tension. An 8 oz. bottle or larger is what you want.
