For a variety of reasons need to urgently move into a newly built house. Finances are extremely limited, in connection with this question arose the need to make the most budgetary repairs only in the most necessary rooms, most likely by their own efforts, no experience. There are no special requirements for quality and appearance, I just want the walls do not dust and did not look quite bad.
Please advise which is the best way to repair the walls? The walls are flat, made of aerated concrete and brick.
Buy water-based paint, tint it to the right tone, paint with a roller. It will look like a loft. It's also the cheapest and best option. All you can do yourself and strong requirements for the accuracy of the work is not.
Rails and drywall, fast even, after caulking the seams paint/glue, any options. A basic option, but very decent. On top as I mentioned there may be variations. You may have to go to a craftsman to install, but if you want you can do it yourself.
