This is how renovation plaster can be processed correctly

Restoration plaster can be easily processed with a brush, a smoothing trowel or a felt board made of wood or plastic. Here's how it works.

Restoration plaster and its properties

Restoration render is a very open-pored material that is also considered water repellent. The existing or resulting in a masonry moisture evaporates already in the plaster layer, at least according to the manufacturer. This allows the wall to dry without you having to deal with salt efflorescence. Restoration plaster offers you a number of advantages:

  • Restoration plaster is suitable for drying damp walls and protecting them from moisture.
  • The plaster layer absorbs building salts and thus protects the masonry from major damage.
  • Restoration plaster is a practical solution where house walls can not be treated externally without great effort (for example, in the basement).

Important preparations before processing

It is very important that the substrate is free of components such as formwork oil, dust or other contaminants before processing the restoration plaster. In addition, you should make sure that the work should be carried out only at temperatures of more than 5° Celsius. This temperature should not be undercut during the first few days during the drying process. Also avoid temperatures over 30° Celsius. It is best to take the technical data sheet of the material at hand. Also, when plastering indoors, ensure adequate ventilation during the drying time. With an air humidity of more than 65 percent, the restoration render can not dry out properly, which can impair its functionality.

Restoration plasters process in a simple way

Before applying the new renovation plaster, it is very important to completely remove the old plaster. In addition, you should make sure that you scratch the joints also at least three inches deep before the new plaster is applied. To improve the adhesion, the wall must be moistened. Then follows the application of the material. The easiest way to do this is to first apply the restoration plaster only about 10 millimeters to the basement wall before applying further layers with a total thickness of about 30 millimeters. About two hours after processing, the plaster layer can be smoothed out with a smoothing trowel, a wooden or plastic cleaning board or alternatively a brush. If everything is completely dried out, silicate paint is the ideal material for painting.
