Application

The Knauf Sevener plaster-adhesive mixture has special qualities that make it suitable for both internal and external work (see How to plaster external walls).

Use options

It is evident from the name alone that this construction mixture is multipurpose and can be used as an adhesive or plaster.

The following kinds of work are meant to be done with it:

  • Repair of old plaster on building facades, including structural surfaces and those covered with paints and varnishes, provided that they do not crumble and are firmly attached to the base;

  • Application of thin-layer intermediate plaster on smooth concrete and structured surfaces of mineral plaster, on coatings based on artificial resins and surfaces with a dispersion coating;
  • The device of the clutching plaster bridge on the surfaces of porous or smooth concrete;
  • Gluing thermal insulation boards made of mineral wool or expanded polystyrene to the base when installing external thermal insulation systems;
  • Installation of a protective layer with fiberglass reinforcing mesh on top of heat-insulating boards.

Kindly take note. The Severin mixture coating serves as a perfect foundation for later finishing with materials like Knauf Diamant decorative plaster or Goldband Knauf leveling plaster mixture.

Additionally, the amount of dry mixture used per square meter of surface varies depending on the application method. For instance, Severin Knauf dilutes the plaster mixture at a rate of 3.5 kg/m2 when adhering insulation to a level surface; 6 kg of this mixture is needed if masonry is lined with thermal insulation boards.

Similarly, plastering even surfaces requires less material (5 kg) than layering over old structural plaster (6-7 kg). Creating a reinforced protective layer on the insulation’s surface also results in maximum consumption.

Features of application

Whatever the purpose of using the Knauf Sevener plaster mixture for, the base needs to be thoroughly cleaned to remove any dust, debris, and crumbling particles.

After that, the solution is ready; the package contains preparation instructions. Generally, 25 kg of dry mixture require 5 liters of water to mix.

As a point of reference. Mortar mixing pumps are used to apply the finished mixture mechanically or manually. They run continuously.

The prepared solution should be used in such a way that it can be finished in two hours if applying it yourself. It will start to lose its properties after this point.

Positive air temperatures are ideal for work, and newly applied plaster needs to be shielded from frost, direct sunlight, and excessive drying rates.

It must be allowed to fully dry before proceeding with the work and covering the surface with Knauf Isogrund primer and leveling or decorative Knauf plaster mixtures.

The KNAUF SENENER plaster-red mixture is a good option for anyone searching for a dependable and effective wall finishing material. Because of its unique qualities, which include strong adhesion and ease of application, it can be used on a range of surfaces. This mixture produces consistent results that both professional builders and do-it-yourself enthusiasts can appreciate, whether they are working on exterior or interior projects.

The versatility of the SENENER mixture is one of its most notable qualities. Its exceptional coverage is intended to help create a level, smooth surface that is prepared for additional finishing. Its composition also guarantees durability, protecting your walls from deterioration over time.

All in all, KNAUF SENENER 25KG is a plaster to take into consideration if you’re looking for one that strikes a balance between quality and usability. It lives up to expectations, giving you a superior finish with the least amount of trouble.
