I am a professional wallpaper hanger and I have used this solvate ready mixed paste for some of the most expensive wallpapers, however, it can be used for all different types of papers as well. I usually use this by applying the paste with a thin pile roller and tray as it makes the paste so much quicker to put on and evenly spreads out over the wallpaper. I also find that some papers will recommend that you us a ready mixed paste like solvate as It allows the paper to slide nicely across the wall, it will also give you a really good adhesion onto the wall.
Ready mixed solvate paste also saves the time and mess of mixing up your own paste. I find it usually does paste up to the number of rolls that it recommends.
I would recommend solvate ready mixed paste to both the professional and diy'er. On the plus side I find that as long as you close the lid you can use any unused paste at a later date, as long as the paste is still within its shelf life. Also this glue does not give off any bad oders.
Overall this is a good product that I would recommend.
