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 four to five 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 three hours.

Work instructions
The lowest working temperature is +5°C. The temperatures of the bricks and plaster must also be above +5°C, and the bricks must be dry and absorbent. The bricks are laid with around 10-13 mm joints or as open joint masonry, in which case pointing is done using Fescon grout. Use Fescon Masonry Mortar and weather-resistant bricks for the masonry of the cold flue section (flue above the roof). Follow the instructions of the designers and official regulations in masonry work.
After treatment
After the bricklaying, the temperature should remain above +5°C for at least 5 days. Before taking the structure into use, allow it to dry 2-3 weeks with all hatches and dampers open. Perform the first, careful heating with a heater blower, for example. Next 3 to 5 days, heat carefully with a small fire. Leave the hatches and dampers open after each drying heating.
