Refer to the bag for how much water the plaster requires. Add the dry material to the water and mix with a concrete mixer for around ten minutes. With a power mixer or a drill paddle, around one to two minutes of mixing is sufficient. Allow the plaster to stand for around ten minutes and mix it again for a short while. Find the correct consistency at this stage by gradually adding the rest of the water. We do not recommend adding all of the water right at the start. The finished plaster remains workable for around two hours.
Repair deep cavities with repairing plaster (1.2 mm or 3.0 mm). Allow the patches to harden as long as possible before coating the entire surface. The surface of the patch must be as coarse as possible. You should not float the surface to bring the cement paste to the surface. Clean the entire base of loose dust and dirt, for example by pressure washing. The surface must be damp enough to be darker in colour before coating begins. The best time to wet the surface is the previous night.
Spray the Fescon Overlevelling Plaster all around in a layer 1-2 mm thick. Level the surface if necessary. You should not float the surface to bring the cement paste to the surface. After the surface has hardened for at least a day, spray a second layer of overlevelling plaster, if necessary, into a layer about 1 mm thick. Level and float or brush the plaster into the desired profile. You should always carry out the finishing very carefully in order not to reduce adhesion to the base. The surface can also be left be unfinished after spraying.
You must care for the coated area by spraying with water and/or protecting it with a plastic film. The need for aftercare depends on the conditions, and it should last at least 1-3 days.
