It is best to replace the ladder with ordinary construction goats. Yes, they are noticeably heavier, they look unpresentable, but they are comfortable to stand on. The plus of building goats is that you can make them yourself, from scrap materials, old boards, a disassembled interior door, for example. Moreover, the height of the goats can be adjusted in the process of their creation, that is, you can easily build with the help of boards, bars, old furniture, nails and a hammer a structure that will allow you to conveniently paint and glue it on your ceiling. On sufficiently wide and strong trestles, you can work together, which is very convenient when gluing wallpaper on the ceiling.
An ordinary table can replace construction goats. If you do not mind using it in repair work, you hope to either wash it later, or send it to the dacha – it is quite a convenient option to glue wallpaper or paint it “from a hill”. The main thing is that the legs of the table do not stagger, and he himself is high enough.
Painting the ceiling straight off the floor is much easier than painting it with wallpaper. You only need a paint roller, but not a simple one, but on a long handle. Yes, it will be difficult to work at such a distance from the surface to be painted, you have to keep your head up all the time, wield a long handle, make sure that the entire surface of the ceiling is painted over … But nothing is impossible if there are no stepladders and trestles, and repairs need to be done. In hard-to-reach places, in corners, you can use a paint brush, also attached to a long handle.
For pasting wallpaper on the ceiling without a stepladder and a construction goat, that is, from the floor, a roller or a brush with a long handle will also come in handy. You also need to apply some wallpaper glue to the prepared base! But as an additional device supporting the cut, prepared piece of wallpaper, you can use just such a mop with extended “shoulders”. The width of such a device should correspond to the width of the wallpaper strip. We admit that in this way it will be more difficult to glue a roll of wallpaper one meter wide. Easier to deal with 50 cm strips.
