Loose Stretched Canvas
Tight'n'Up
Canvas for stretched paintings can become loose over time. This can be due to the high humidity, and changes in the frame tension, or simply due to age of the work.
There's an easy and safe fix however. Tight'n'Up spray made with acrylic binders can be applied on the the back of the painting. In my experience, spray the back of the painting generously and let it wait for 24 hours. You might have to "air out" the work too for a few days. And problem solved!
This spray also helps with sagging canvas, wringles and ripples on the canvas as well
Plexiglas/Acrylic Cleaner and Polish
Brilianize
If you have acrylic/plexiglass prints, or artwork covered with plexiglass, then you might want to get this spray.
Plexiglass is lighter and safer at home than glass. For this reason, Art House SF prefers framing our paper artwork with glare-free museum-quality plexiglass. However, plexiglass is less scratch-resistant than regular glass. Over time, if you noticed small scratch or jsut want to refresh your plexiglass surface, this spray by Brillianize is your best friend.
And by the way, New York MOMA, Smithsonian, National Park Service and Disneyland are using it too.
