It is better to have a spiked roller in your arsenal when laying self-levelling compound. Spiked rollers are moved across the surface to release tiny air bubbles trapped in the self-levelling compound. As the name suggests self-levelling compound will want to find its own natural level. All it needs is a little encouragement, you should not need to be spreading it around the room on your hands and knees with a trowel. Not only will this distribute the self-levelling compound perfectly around the room forming one smooth flat surface but it will also get rid of those pesky air bubbles for you. Can a trowel do that, eh! Spiked Roller Removing Air Bubbles You use a self-levelling compound to turn a bumpy, un-even subfloor into a perfectly smooth surface.

When applying a self-levelling compound less is sometimes more. Simply pour your self-levelling compound then run through it with a spiked roller.

When you mix your self-levelling compound with a whisk or a mixer it can add air bubbles. The problem is, once you have started to pour your self-levelling compound you can’t stop. If you see any air bubbles in your mix and you don’t have a spiked roller to hand, it’s too late. It is called a self-levelling compound as it, in theory, self-levels. What this means is that you don’t have to worry about getting the mix perfectly level. It should flow across the floor, and correct any errors. While this does generally work, there are limits.

With regard to subsequent removal, there are two categories of paper-based wallpapers: "easy to remove" and "dry stripping". Dry stripping means that the top wallpaper layer (decorative layer) can be easily removed from the wall, usually without any support, while the bottom or carrier layer remains on the wall. The latter has to be removed by soaking it and scraping it off. Depending on the state it is in, the bottom layer might be left on the wall as lining.
