For putty, 2 spatulas will be required — the main and additional. We put the main putty, we remove the excess auxiliary. Don’t choose too big spatulas. If you are not a professional in this matter, then it will be easier for you to work with medium -sized spatulas. The smaller the width of the spatula, the more accurate the work is obtained. Put their putty either over the entire surface of the wall, or pointwise — to places that require alignment.
