25 kg 4002 Lotti Plast Thermal Insulation Board Plaster Mortar – Fiber Added (Thick) is added into approximately 6-7 lt of clean water and preferably mixed with a low speed mixer so that no lump remains. The prepared mortar is left to mature for 5-10 minutes and used by mixing again for 1-2 minutes. The mixture in the container should be consumed within 2 hours.

At least 24 hours after the doweling of the thermal insulation board, first layer plaster of 2-3 mm thickness is applied on the boards with a trowel. When the applied mortar is still wet, the Plaster Net is pressed from top to bottom and stretched and embed in the mortar. After approximately 6 hours, the surface is moistened and covered with a second layer of plaster (2-3 mm thick) and smoothed for painting. To prevent cracking, the net is overlapped by 10 cm at the joints. Depending on the weather conditions and application thickness, it is necessary to wait 2-3 days for the paint. If the air temperature is high after the application is completed, moisten the surface until the cement sets.
