Mixing by hand

Description

Mix 1 or 2 bags each time with an electrical blender (minimum 1 200 W or (better) 1 800 W) until a homogeneous paste is achieved without lumps. Depending on the product, you will need from 10 to 15 litres of water per bag. Put half the water in the receptacle, sprinkle on the plaster, then add the remaining water. Adjust the consistency of the paste by adding either water or plaster as required. The paste should stick to the wall in a 3cm thick layer without flowing down.
Once the paste has been applied and the receptacle is empty, pour in the water for the next mix and use a hard brush to clean the sides and bottom of the container before adding new plaster.
