Clean the surface of all dust, oil, dirt and other impurities.
Place the appropriate amount of water in a clean container, then add gypsum until it covers the water surface.
Wait 2 to 3 minutes, then mix manually or with a slow mechanical mixer until the mixture is homogeneous and free of lumps.
First stage: fill the board joint with the prepared filler.
Second stage: place Joint Filler over the glass-fibre tape. Once the first layer dries, level any surface projections.
Apply a second filler coat approximately 20 cm wide so it is level with the gypsum-board surface.
The filler begins to set after 80 minutes.
