Spray cotton plaster on walls and ceilings

Cotton plaster can be splashed well on a wall or ceiling. Especially for larger areas, the type of application is suitable. However, the time required is similar to the leveling and stroking method, as more operations and more extensive preparations are necessary. The consistency of the plaster can be well perfected.

Construction and appearance

When cotton plaster is applied, it can be painted or sprayed. In terms of time, the two methods are hardly different in normal housing dimensions. The optical appearance of the surface receives a rougher and usually more uniform structure in the sharpening process.

The layer thickness of a cotton plaster is about three millimeters. When peaking this material thickness is achieved in two to four passes. After each shift, a dry phase of at least 24 hours must be carried out. At temperatures below twenty degrees Celsius and low air exchange rate, the drying time can increase up to 72 hours.

Stir and try

When processing cotton plaster that is sprayed, approaching the ideal consistency is the best way.

1. Fill a "handful" of the mixed, watered and drawn plaster in the funnel of the spray gun and trigger.
2. If nothing comes out, admit a "handful" and try again.
3. Repeat until the first time plaster sprays out of the nozzle.
4. Each "handful" of water equates to about ten percent water on the amount of plaster
5. According to the number of rehydrations of the sample, rewash the entire render in the same ratio.
6. Let it swell again for at least six hours, longer for more than ten liters

Large-scale and unspecific distribution behavior

When the plaster is ready to spray, it is applied from the wall corners to the center. The relatively "sparkling" distribution is fun, but must be prepared by protecting the windows, frames, doors, floor and baseboards.

The conventional spray guns with a funnel need an elbow which is screwed in when the spray plaster is applied to a ceiling.

Tips & Tricks

The "liquid wallpaper" can be splashed well on surfaces. When applying the spray plaster, make sure that the chemically harmless textile plaster also contains glue against which you must protect your skin and eyes.
