Instructions for use

The surfaces to be plastered must be clean, dry and free from dust. A new coat should not be applied until the previous one is dry. If needed, the surface should be carefully sanded and cleaned before applying a new plaster coat.

Kiilto J is a ready-mixed plaster. After long storing, stir before use. The product can be diluted with water, if needed. Fixing of reinforcing tapes: Apply the plaster in joint and press the tape firm in plaster with a narrow steel trowel. After that smooth the joint by applying plaster over the reinforcing tape using a broad steel trowel. After drying the surface can be sanded, if necessary. If the board edges are not thinned, smooth the plaster widely enough outside the joint to have a smooth finish. In this case also the edges of the gypsum board are tapered.

Reinforcing tape can also be fixed to gypsum board with a special plaster machine. The product can be diluted with a small amount of water, if needed. Check also the gypsum board manufacturer's instructions.
