The spray has a gloss-eliminating effect (weak). If sprayed on gloss paper it will result in a semi-gloss finish. Not suitable for smooth and matte finish printer paper. It can also reduce effects of humidity thereby protecting papercrafts for a long time. I recommend spraying outside because of the strong odor. This has only been tested on inkjet paper, not laser paper. Please refer to the website links for detailed features and prices.
