If you have ever done finishing work indoors, you must know that a primer is needed to carry out repairs. Its composition usually includes pigments, accelerators and fillers. It is used for application on porous materials that have a high absorbency. Among others, Nortex-soil, which is quite popular in the modern building materials market, should be highlighted.
Description of Nortex primer
"Nortex-soil" is a composition that is made on a water basis and is used for the treatment of stone, brick, wood, as well as gypsum surfaces. After drying of the applied layer, you can proceed to surface treatment with a water-dispersion dye.
This primer fills the pores, strengthens the base and extends the life of the material, increasing adhesive characteristics. Using this composition allows you to save dye, which is applied in the next step.
Customer Reviews and Key Features
"Nortex-soil" is chosen by modern customers more and more often, because, in their opinion, this mixture has many advantages, among them it is necessary to highlight:
- possibility of use for all types of surfaces;
- antiseptic properties;
- the possibility of tinting;
- lack of organic solvents.
If we compare this primer with analog compositions, then we can say about the first that it has antiseptic properties, and this is very popular with customers. Consumers emphasize that the mixture can be tinted using pastes used for water-dispersion paints.
“Nortex-soil” is also chosen by customers for the reason that it is completely safe, because there are no harmful substances in the composition. Even a novice master can cope with the application, and you can use a spray gun or brush for this. After covering the walls become white, the base is devoid of wrinkles and craters.
Specifications
"Nortex-primer", the characteristics of which should be known to you if you plan to use this material for repairs, is a white composition, the density of which varies from 1 to 1.02 g / cm 3 .
Some experts are also interested in the pH level, which in this case is 7-9 units. You may also be interested in conditional viscosity, which is determined by a viscometer at an air temperature of +20 ° C. This parameter ranges from 40 to 42 seconds. Primer “Nortex-primer” is consumed in a volume of 90 g / m 2 , this is true if the application is carried out in one layer on a wooden surface. This parameter will change if concrete or stone surfaces are used as the base, the flow rate will be higher and will be equal to the limit of 120 g / m 2 .
If you use a gypsum plasterboard surface as the basis, then the consumption will slightly decrease and amount to 60 g / m 2 . Application of the soil should be carried out at a temperature in the range from +5 to +30 ° C. The drying time of the surface may vary depending on the ambient temperature. If this parameter is +20 ° C, then the drying time can be 30-60 minutes.
Composition and purpose
Nortex-soil, the technical characteristics of which were described above, consists of an aqueous dispersion with the addition of acrylic. A mixture is used to strengthen and adhere the bases, which can be achieved by filling the pores with small polymer particles. The mixture is well bonded with coatings, increasing their service life.
Using the composition, the occurrence and further development of wood-staining and mold fungi can be excluded. After applying such protection, the painted surface acquires a layer that resists biological damage such as blueness, mold and fungus, and also exhibits weather resistance.
Application
Acrylic soil “Nortex-primer” is intended for the preparation of brick, wood, concrete and plaster gypsum surfaces before applying water-dispersion paints and varnishes. The mixture is intended for the treatment of external and internal surfaces, which makes it universal.
Usage Reviews
Consumers quite often choose the primer described in the article for the reason that it is completely ready for use. There is no need to carry out additional preparations for the mixture. The primer will only need to be mixed, then you can begin to apply it.
Consumers emphasize that the surface must be perfectly dry, clean and strong enough. Before starting work, the surface is cleaned of grease and dust particles, as well as old peeled paint and whitewash. Grease and oil contamination should be removed with soap and soda ash. Acrylic primer “Nortex-primer” must be applied to a surface that is washed with water and dried.
Some consumers believe that before applying the composition, the surface must be putty, which will increase the effectiveness of the layer. Buyers advise to pay attention to one feature of the composition, which manifests itself in longer drying, if the ambient temperature during application drops below +15 ° C. This also applies to the polymerization step.
Conclusion
After applying the primer described above, a colorless coating forms on the surface of the walls, floor or ceiling. If you want the base to take on a shade, then color should be added. The manufacturer advises using a mixture of Tikkurila.
The number of layers applied will depend on the quality and surface material. Between the layers should wait about half an hour, which is true at normal humidity and temperature. Further decorative work can be done in an hour all at the same ambient temperature. In this case, the humidity should not exceed 80%, otherwise drying may increase in time up to 24 hours.
