Decorator's varnish arrived quickly and well packed. Unfortunately I was seeking a matte varnish to put on top of wallpaper that was too shiny. Even after 2 coats the wallpaper was still shiny.

Thank you for your valuable feedback and I'm sorry you found it too shiny! I'll let the manufacturers know about your obsevervations. We've used this product on our wallpapers and it worked really well. The varnish is absorbed by the wallpaper and we can hardly detect the varnish on it. Perhaps the varnish doesn't work the same way on all wallpapers. We normally recommend our customers using the varnish on wallpapers purchased not from our company to test the varnish on a small piece of wallpaper before applying it across the entire wall.

Very quick service

I've bought this varnish after putting up beautiful wallpaper a few months ago. The hallway had a vinyl paper originally and now it's ordinary wallpaper. As soon as the cold nights started, I noticed condensation marks forming on the new paper just above the front door. Gutted doesn't start to describe it! I cleaned as much as I could and then coated the paper with this varnish. To be honest I've decided in the spring to take the paper off and redo it but I will immediately apply this varnish in the hope I get no more condensation problems. I can say this varnish leaves no residue whatsoever and is completely invisible. I just wish I had know about a) the condensation issue and b) known about this varnish!

Thank you Sian Zeng for being available via a Google search.
