Add the dry material into the water pouring it slowly and simultaneously mixing it. A concrete mixer or power drill whisk can be used for mixing. With the power drill whisk, approximately 4 minutes of mixing is enough. Let the plaster stand for approximately 10 min. Mix it again for a short while. By remixing, the correct plasticity of the compound is sought by adding the final amount of water. It is not recommended to add the maximum amount of water right at the start.

Before the pipe riser is brought into use, it is allowed to dry for at least two days.

Sealing work of pipe risers requires special tools.
