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.

Clean the entire base of loose dust and dirt. Wet the surface to be plastered until it is darker in colour before beginning the plastering work. The best time to wet the surface is the previous night.

Spray the Fescon Fibre Plaster all around onto the base in a layer 3-5 mm thick. If you wish, you can also spread the plaster manually using a steel trowel. Level the surface by spreading a second 3-5 mm layer of fibre plaster on top of the first layer before coating. Use the Fescon Facade Coatings for coating.

Give aftercare to the plaster surface by spraying it with water. The need for aftercare depends on the conditions, and it should last at least 1-3 days.
