Instructions

Refer to the package for how much water the plaster requires. Add the dry material to water and mix with a drill paddle or other suitable mixing tool for around two minutes. Let stand for a while, adjust the amount of water if necessary, and perform a quick mixing. The workability time of the finished levelling compound is 30 min to 1 h, depending on the amount of water and the conditions.

The surfaces must be solid, clean and dust-free. Carefully remove weak and loose material. Before applying the plaster, use water to wet dry and water-absorbent bases.

Spread the plaster on the base either with a levelling spray or a steel trowel. If you are applying several layers of plaster, you can allow the previous layer to harden or double up using the wet on wet method. If necessary, the dried surface is ground after the application of each layer of plaster. The best result can be achieved by first spraying a thin layer, after which spray wet-on-wet to the desired thickness. Can be overlevelled after around 24 hours. Can be waterproofed after around 7 days.

In dry conditions, wet the levelled surface with a water spray.

Waste handling
