From the qualitative preparation of the surface, the final result of finishing the room largely depends. The most suitable means in this case is the Knauf Tiefengrund primer.
Primer is used in order to improveAdhesive properties of materials before laying ceramic tiles, paint or wallpaper with wallpaper. It is used for processing gypsum boards and their joints before applying putty.
It is a polymeric emulsion of white color, which dries quickly enough and does not have solvents in the composition.
The consumption depends on the absorbencybase and averages from 70 to 100 g / m2. For complete drying, a maximum of 2 hours is required. Store the primer and carry out all work associated with its application, it is recommended at a temperature of 2 to 25 ° C. Shelf life - 12 months from the date of manufacture, indicated on the package.
Due to its high penetrating powerKnauf Tiefengrund primer significantly strengthens the surface of the substrate to which it is applied. It is deeply absorbed in the porous materials, fills all the free space between the hard particles, and after the water evaporates, glues them together. Thus, the material structure is additionally cemented. Due to its vapor permeability it is able to provide a comfortable microclimate in the room, allowing the walls to "breathe". Primer of this brand is hypoallergenic, does not contain toxic substances and is absolutely safe for health. It can be used for both internal and external work under temperature conditions.
Before applying the primer, the surfaceit is necessary to prepare. It is cleaned of old paint, grease stains, dirt and dust, and then dried. The prepared surface must be absolutely clean, dry and strong.
Before you start, you need to carefullymix the contents of the package to a homogeneous mass, since the solution has the property of settling. Dilute with water it is not required. It is not recommended to add to the primer and any other materials. This can adversely affect its properties. Primer "Tiefengrund Knauf" is applied with a roller, brush or brush. It easily spreads, forming a uniform thin layer.
If the surface covered by the primer hashigh hygroscopicity and porosity, the composition is applied twice. The second time the primer is used only when the first layer is completely dry, but it is advisable not to tighten the time, because the surface to be treated can be dusted.
At the end of the work, all tools are thoroughly washed with water. Do this immediately, because the dried primer "Knauf Tiefengrund" is only removed mechanically.
