• The composition is poured into a container made of plastic.
• Pure water is poured inside (16-20 liters are required per package);

• The solution should settle (about 5 minutes).
• The mixture is mixed again.
• The foundation is ready, you can start working with it.

The following recommendations should also be considered:

• Do not add water, dry concentrate or other components to an already prepared solution.

Methods of dilution and application.

Prospectors white gypsum plaster is applied to a dry, clean, uniform surface:

• For applying the finished solution, a manual or mechanical method can be used.
• In the first case, the mixture is applied to the workable base with a trowel, putty knife in layers whose thickness does not exceed 50 mm. The surface is leveled.
• If it is planned to perform plastering in several layers, then it is recommended to pass the first with a coarse trowel. This will provide better grip.
• The layer sets in 2 hours. This work can easily be done with your own hands.
• Using the semi-mechanical method, the application is made using the pistol with movements to the left (top), moving down. The solution should be distributed in strips (length 70-80 cm, width 7 cm), each of them should overlap the previous one, as in the video. This article describes only the features of the composition.
• The prepared mixture is applied to the ceiling by movements from left to right. The process should start from the wall opposite the window.
• The formed layer thickness depends on the speed of the pneumatic bucket (if you move the gun faster, the thickness is less).

Full automation is achieved by using special equipment that is used when performing work in large volumes.
