Can spray paint or paste ceramic tile to the fiber cement board wall surface to carry on the decoration. Before wall decoration, caulking should be carried out. Before caulking, the seam must be cleaned, and the moisture content of the board should be less than 17%. The caulking materials can be building sealant, elastic caulking putty or acrylic putty. The external wall is made of elastic caulking putty, which is concave and round, and the concave depth is about 2mm. The interior wall can be made into concave circle, or full inlay or trade seam. Full embedding should be carried out twice to avoid shrinkage cracks.

The paint can be sprayed after the board surface is dry and 48h after caulking. Before spraying, check whether the board surface and joint are clean. The exterior wall generally adopts acrylic exterior wall coating, and the interior wall adopts acrylic interior wall coating. In general, special ceramic tile adhesive should be used to paste ceramic tiles on fiber cement board. 901 glue and cement can be mixed as putty for sticking, and its consistency should not flow.
