Primer Сeresit: characteristics and application

The German company Ceresit is known worldwide. For more than a hundred years, it has been producing the highest quality building materials. In the late 90s, the production facilities of this giant of the construction industry appeared in Russia and quickly won the recognition of the domestic consumer.

Primers Ceresit are water-dispersion mixtures based on polymers. The components include a variety of additives that significantly improve the consumer properties of the soil.

Primers of this brand are widely used for the preparation of surfaces of different types: from a tree, porous concrete, a brick, metal and plastic to finishing decorative finishing. The composition guarantees high quality of work.

Advantages over primers of other brands:

• increases adhesion of materials at the time of painting, wallpapering, plastering and cladding ceramics;
• reduces the absorbency of the coating, as a result, the consumption of paint and glue during subsequent work is significantly reduced.

We should also mention the protective properties of the primer. A mixture of deep penetration of this brand helps to improve the properties and quality of any surface. The active ingredients of the composition penetrate into the fibers and glue their particles, both outside and inside. Due to this, the surface is strengthened and its destruction is prevented. The use of primers helps to prevent the occurrence of deformation on all surfaces except non-absorbent. They also prevent the destruction of decorative finishing materials that are applied to the surface treated with the composition.

The primer reliably protects the surface from dust settling - cover it with the composition and see how it glitters. Its use prevents the drying of a thin layer of leveling mixtures and the formation of bubbles on its surface.

In other words, the use of Ceresit primer results in saving materials, increasing the durability of the finish and maintaining a favorable indoor climate.

The advantages of the mixture also include environmental safety. - the coating does not contain harmful and toxic substances, there are no solvents in its composition, therefore it is absolutely safe for use in residential buildings and apartments.

It is noteworthy that the company has established the release of spiral cold-resistant compounds by adding special components, which made it possible to use the primer in the winter season even in unheated rooms. By the way, the use of primers produced by this company does not change the vapor permeability of the base, so they can also be used in areas equipped with heating. This is a truly universal composition, equally good for use in high and low temperatures.

The disadvantages of the mixture associated with its value., but if you look, the pricing policy is very profitable. The composition is sold in containers of 1, 5 and 10 liters and with an increase in volume, the cost per liter decreases, therefore, when carrying out large amounts of work, you can significantly save on its purchase.

Installation of insulation materials, painting, sticking vinyl, non-woven or paper wallpaper, laying leveling masses for the floor and cladding plates is not a complete list of finishing works that require the use of Ceresit primer. With this mixture, the base can be significantly compacted, and after the soil dries out, the strength of the treated surface will be increased, but air circulation will remain at the proper level. This property of the composition is especially important when it comes to laying steam and waterproofing in the room.

The use of these mixtures is quite popular during construction and finishing works.

This type of soil is used for the following surfaces:

• concrete;
• gypsum;
• cement;
• Engine and chipboard;
• drywall;
• gypsum fiber;
• paint coatings.

Its functions are also wide:

• reduction of moisture absorbent surfaces before laying tiles;
• surface preparation for plastering and flooring;
• preliminary preparation of the coating prior to the installation of insulation or painting;
• processing of porous concrete, drywall, cement plasters, and chipboard.

Regardless of the similarity of ST 16 and ST17 p when conducting facade work, it is worthwhile to give preference to the CT 17 grade. The reason is its versatility. As you know, outdoor work is carried out in several stages - this priming, and applying plaster, and painting. At the same time the primer is used in each of the listed stages. There is no doubt that it is more profitable to acquire one single universal mixture of deep penetration, rather than buying many different compositions for each individual stage of work.

Ceresit primers are presented in a wide range - universal deep penetration compositions, concrete contact, concentrated mixture, antifungal primer and others. Let us dwell on the most popular varieties.

Ceresit ST 16 is widely distributed when carrying out external and internal works. Soil strengthens the base and increases adhesion. The mixture includes a special color scheme, thanks to which the surface after treatment acquires a super-white color and can be used for thin light wallpaper or paint.

The primer of this modification is produced in the form of a thick liquid. Its structure includes an aqueous dispersion of acrylic-based polymers, enriched with mineral fillers and pigments. The active component of the primer is quartz sand of the smallest fraction - it increases the surface roughness and improves adhesion.

Characteristics:

• Primer is used at positive temperatures in the range of 5-30 degrees Celsius. Drying speed is 3-6 hours, and material consumption is 0.3-0.5 kg / m2.
• The primer is available in white, however, the unique parameters of the composition allow the use of tinting - this is veryoften used when working with decorative plaster - the base is not translucent and the color solution looks perfect.
• Differs ability to reduce surface moisture.
• The mixture is implemented in a ready-to-use form, it does not need additional preparation.

The main component of the soil CT17 is an aqueous solution of synthetic resins. The primer has a yellowish tinge. It is used at t from 5 to 30 degrees Celsius, dries about 4-6 hours. Material consumption depends on the type of surface and on average is 0.1-0.2 kg / m2

CT17 is applied on concrete, gypsum plasters, cement coatings and brick foundations. The price of a pack of 10 liters of primer of this modification in 2017 was 600 rubles.

This is a concrete contact used for concrete surfaces. The mixture is called adhesive because it significantly improves the adhesion of the concrete base with plaster, putty, glue and other materials. IN 10 However, the coating is suitable for impregnation and other bases: cement, tile, drywall, gypsum fiber and others.

The primer is effective at temperatures from 5 to 35 degrees, the drying rate is 4-6 hours, its consumption is in the range of 0.1-0.2 kg / m2. Produced in buckets of 5 and 15 kg, the cost of the latter was 1,200 rubles in 2017.

Another popular form of composition from Ceresit. This mixture is used strictly for interior work under the decorative trim. It provides uniform distribution of glue or paints, reduces their consumption, and also binds dust and increases adhesion. The composition is applied to concrete and cement-plaster bases, the material performs well on brick, as well as all types of plaster and putty.

This is a special anti-fungal primer. It is used to prevent the appearance of microorganisms, and in high concentrations - to destroy existing mold, moss and lichen. The mixture has high fungicidal properties due to antiseptic components in its composition. In addition, the primer is safe, environmentally friendly, does not leave behind a streak, and provides high-quality surface coating.Used in work with concrete, plaster and brick. This is a concentrated composition, so it is diluted with water, as a rule, in ratios of 1 to 3 or 1 to 5.

Anti-fungal primer for maximum protection in aggressive conditions of high humidity and temperature fluctuations. The cost of one liter is about 350 rubles (according to 2017 data).

The assortment list of Cerezit primers includes a universal mix, a deep penetration concentrated primer, a composition for absorbing mineral surfaces, a base for decorative plaster and concrete contact for the treatment of surfaces with increased absorbency.

Suppose if the surface is old, partially collapsing and crumbling, it is worthwhile to give preference to primers CT17 - they penetrate deep into the base, connecting its particles and thereby protect it from destruction. The same composition is optimal when working with chalky coatings. The primer of this modification has frost resistant varieties designed specifically for use in low temperature conditions.This allows you to carry out facade work in the winter, as well as repair unheated premises in winter.

For the treatment of absorbent bases of the floor - concrete, fiberboard, gypsum fiber, gypsum screeds, anhydrite compounds and cement-sand mixtures, the most effective primer for mineral bases is Ceresit R 777. It reduces the absorption capacity, stimulates the spreading of mixtures over the surface and binds all dust. It can be used in interior decorating works only in heated premises.

Under the decorative finish (plaster) is better to choose CT16. The composition is optimal for acrylic, silicone, silicate plaster, as well as acrylic paints. It is used for interior work, but it can be used at the stage of facade insulation when building external insulation systems.

Well, in especially "hard" cases when it is necessary to process cast concrete, glass, or lay tiles on a tile, use concrete-contact mixture. It will ensure maximum efficiency and durability of the finish.

Primers Ceresit are very popular in the domestic market. This is evidenced by numerous consumer reviews.Users note a wide range of products, allowing them to choose the composition “for every occasion”, and also note the quality and durability of the coating. The composition is very economically consumed, and in addition, helps to reduce the consumption of wallpaper glue and paint, which are applied to the surface during the finishing works.

Many consumers have noted the high cost of the mixture.which is slightly higher than the prices of domestic counterparts. However, Ceresit gives a higher quality of coating and guarantees its durability, which makes the use of the mixture optimal from the standpoint of price / quality.

It is made of natural materials, which makes it safe for humans. This quality is especially distinguished by a family with children and people suffering from chronic allergies and bronchopulmonary diseases.

Before starting work, it is necessary to prepare the foundation - this stage will be the guarantee of high quality, practicality and durability of the coating. The surface should be cleaned from stains of grease and various oils, a special brush should be used to scrape off dirt and dust, remove elements of the former coatings and mastic.Before the first application of the soil, it makes sense to check the foundation on the fortress - for this purpose it is carefully probed and tapped, the identified problem areas are plastered and leveled.

Mold, fungus, moss and other colonies of dangerous microorganisms need to be treated with antiseptic fungicide formulations.

Next, apply the composition. Please note that the primer does not need to be diluted with water - Ceresit products are already sold in liquid form ready for use - just stir them. Soil is applied with a brush. Paint rollers are not suitable for this. The composition should be applied evenly thin layer, trying to prevent the formation of puddles and drips.

The primer dries to 6 hours. The hardening rate depends largely on the conditions in the room, humidity and temperature, the presence of ventilation and access of UV rays. The quality of the coating is checked experimentally - paint or glue is applied to a small area of ​​the treated surface, and if the material dries unevenly, then another layer of primer is required.

In any case, porous materials are primed twice.

Ceresit Primer Saves Material Consumption, improves the quality of the coating, increases its use. That is why these blends are the choice of professionals all over the world.
