Before starting to refresh the ceiling, wash off the old whitewash. This is not simple and quite painstaking, so it is worth listening to the recommendations of specialists who will help to correctly solve the task. Most often, such work is performed when it is planned to make gypsum products, which will decorate the ceiling.
After the floors are laid with newspapers, you need to take a spray gun and sprinkle ordinary water to the ceiling. No need to try to wet the entire ceiling at once, since it quickly dries, which will further worsen the work. To solve the problem, it is best when small areas are wet.
Next, the whitewash with the help of a spatula carefully remove. Wet whitewashing is very easily removed. After the main whitewash is removed, it is necessary to remove the remains. To do this, you can apply a sponge. Wash off the rest more than once. Unfortunately, it is simply impossible to remove all the whitewashing at a time.
In the case when you are going to fix the products from gypsum, you should not primer the bare ceiling, since you cannot get a good result.
Additional ways to remove whitewashing
In addition to the above method of removing whitewashing, there are other.
One of them is a sticker on old newspapers. The edges should be left without glue. Then it will be easier to grab for him. After waiting for the drying of the glue, the newspapers are carefully removed. At the same time, peeling off, the newspaper will take a layer of whitewashing with it.
Having completed the cleaning of the ceiling, you can proceed to the consolidation of gypsum products. Of course, if the installation of a stretch ceiling is planned, all these recommendations are not needed.
