Cladding with ceramic plates, layingleveling masses for the floor, fixing heat insulation materials, painting, wallpapering - this is not the entire list of construction works, before which the material Ceresit CT 17 is used. Why should it be applied? This liquid primer penetrates into the pores of the uneven surface, thereby reducing its absorbency, which further allows for better adhesion of the subsequent material to the substrate. The primer is universal and indispensable for any repair.
An indispensable condition for facade and interiorwork is considered the treatment of the surface of a special liquid, which has in its composition the binding elements. This requirement is required in order for the porous surface to be prepared for application of the subsequent layer. For example, if you do not apply the primer to the plaster, and immediately start to glue the wallpaper on the finishing coat, then the adhesion surface of the latter with the surface decreases. The justification of this fact is that the adhesive will penetrate partially into the highly porous layer of the plaster, and the wallpaper starts to gradually move away.
When the walls, the ceiling is applied primerCeresit CT 17, the layer is sealed - its particles penetrate deeply into the material and harden. Therefore, the treated surface, in addition to strength, also acquires smoothness.
It is known that modern facing construction works are undesirable to be carried out without the use of a primer. But why? The answer will prompt the functions of the water-dispersion liquid:
The manufacturer stated that primer water-dispersive Ceresit CT 17Universal and can be used to apply to a surface that has a variety of physical properties. Indeed, the scope of the composition of this modification is impressive: the treatment of internal and external surfaces before painting, ceramic veneering, plastering and so on.
But there exists in the technical characteristics of the dispersion composition a list of surfaces on which the functions of the primer are performed according to the laid properties:
For all listed bases shouldmeet the requirements of SNiP. The surface must be clean and dry before handling. Old paint, dust, lubricants should be removed beforehand. Defective areas that are on the verge of exfoliation, also need to be eliminated, and the surface is under repair. Constructional elements that do not require treatment with Ceresit CT 17 are recommended to cover with paper or film.
By structural composition of the deep primerThe penetration of the Ceresite brand is an aqueous solution of polymers. On color execution - it is liquid of a yellowish shade. By smell, the primer Ceresit ST 17 should not resemble PVA glue, otherwise it is a sign of low-quality material. The temperature at which normal use of a dispersion liquid is allowed, only positive - from 5 to 35 degrees. Therefore, it is better not to perform facade work in the cold season, unless you purchase the winter version of the Ceresite primer. Priming efficiency is achieved at a humidity of 60% and an optimum temperature of +20 degrees. The layer treated with the composition of deep penetration ST 17 should be thoroughly dried, as a rule, this time is 6 hours.
The consumption for a single-layer coating, declared by the manufacturer, is 0.1-0.2 liters per 1 m2. However, depending on the physical features of the treated surface, it can vary.
The composition of Ceresit CT 17 has the following characteristics:
To the building materials market ST 17it is delivered in polymeric cans in volumes of 2.5 liters and 10 liters. The cost of the primer in November 2015 is an average of 300 and 550 rubles, respectively. It is more profitable to buy a dispersion liquid in a large volume. Since the technical characteristics of Ceresit CT 17 primer are universal, this allows it to be used at different stages of construction and for an extensive group of surfaces, so the material can replace similar formulations with a limited spectrum of action. It turns out savings on the material and the cost.
Dispersion polymer liquid is stored at room temperature for up to 12 months, which makes it possible to apply the primer at different stages of construction work during the year.
