Technical characteristics of the Ceresit ST-16 primer, properties and consumption per m2

The Cerezit company has been operating in the market of paints and varnishes and polymeric materials for more than 100 years. ST-16, judging by its technical characteristics, is a universal earth from "Ceresit", which is used for the preparation of facades, as well as for decorating various interiors. The primer belongs to the category of polyurethane bases and is produced in strict compliance with quality certificates.

Composition and technical characteristics of the Ceresit CT-16 primer

Primer is a versatile finishing material. With the help of this material, the surfaces are prepared for the application of other decorative compositions, taking into account the characteristics of the surface to be treated.

Primer mixtures have general properties:

• all compounds penetrate deep into the surface to be treated, increasing bond strength;
• the coating eliminates the ability of the surface to peel off, provided that it is properly treated;
• after coating, the quality of moisture resistance increases, but at the same time the ability to pass vapors remains;
• Provided surfaces are properly prepared, the formulations provide additional protection against mold or mildew.

ST-16 has all the properties of the general group, but, in addition, it has some specific characteristics.

Certificate of conformity

The company "Ceresit" has been working in the market of paints and varnishes for more than 100 years. Today, there are tens of thousands of formulation production plants under the center's control.

Primary compliance certificates include a whole list of properties. To pass the control test, the material must comply with the requirements of regulatory documents.

Packing and Release Form

ST-16 is produced in plastic buckets of 5 or 10 liters. The buckets are equipped with a special handle for easy portability. The lid is sealed to the container and provides protection against leaks or evaporation.

Color pallet

Primer compounds are mainly produced in white or gray versions. Ceresit ST-16 is a white primer designed to create a dense layer on the surface.

The white color lends itself well to dyeing. Any color can be added to the base, if needed. Repairers often use the "construction" stain technique to see which parts of the wall have already been treated and which need to be applied.

Cost and storage features

The price of a 5-liter bucket starts from 500-700 rubles. 10 liters of soil can be purchased for 1000-1400 rubles. The container containing earth will keep for 1 year from the date of manufacture, provided the lid is tightly closed. If the paint bucket is open, it should not be stored for more than 3 months.After that, the composition loses its properties, and when applied to the surface, it gives an unpredictable result.

Purpose and properties

ST-16 is produced on the basis of a water-dispersion type, which provides the following properties of the composition:

• The application increases the bond strength between the treated surface and other decorative materials. This is due to the presence of mineral sand in the composition, which makes the surface rough.
• Increases the protective properties of the coating. In this case, the primer is responsible for moisture protection.
• Due to the high degree of penetration into the material of the treated surface, the adhesion property increases.
• Despite the fact that the main color of the primer is white, colors can be added to the composition to obtain any selected shade.
• The composition is completely safe, environmentally friendly, as it does not contain solvents and toxic substances.
• The primer can be used for interior and exterior finishing work.
• There is no need to additionally prepare the primer, as it is ready for use once the container has been depressurized.

Most often, using the "Ceresit" ST-16 primer, concrete, cement, gypsum, plasterboard surfaces, as well as walls, ceilings or floors with mineral coatings are treated.

Concrete, chipboard, lime plaster are treated with a primer.

This material can be considered universal, since it can be used to cover any surface in a short time.

ST-16 is used in bathrooms, as well as in other rooms with high humidity due to the resistance of the substance to moisture. In addition, the following can be considered application areas:

• facade insulation systems;
• reinforced surfaces;
• surfaces intended to be painted with all paints and varnishes.

Advantages and Disadvantages of Requesting Seed Jobs

Working with ST-16 primer has its own pros and cons.

In addition to the listed properties, the advantages of the composition include the ability to work on any surfaces, except metal.

Material consumption calculator

The main question when planning a repair is the correct calculation of consumables. The use of ST-16 largely depends on the condition of the surface to be treated. According to experts, the consumption ranges from 0.2 to 0.5 liters per 1 m2.

Tools required

When working with paints and varnishes, special attention is paid to preparation for work. This concerns the choice of application methods.

For work you need to prepare a bath of paint, a brush and a roller. You will also need a spatula and rags. Basically a brush or roller is used to apply the primer, but sometimes it is more convenient to spray the primer.

Preparing the surface and the working solution

One of the basic rules concerns the preparation of the surface to be treated and the working solution. The resistance of the base to be treated must be checked. Work on surfaces that may crumble, crumble or break is excluded.Every centimeter of the wall is probed, tapped, weak areas are completely eliminated, and then the resulting cracks are covered with a brush or broom.

If voids have formed, they are plastered, and the entire surface of the base is leveled. After leveling, the prepared site is degreased using special means, all dirty spots are removed, the remnants of old paint are cleaned, and traces of dirt are removed from the entire surface.

Mold, fungus or moss is completely removed from the walls, additionally sprayed with special means to prevent the spread of the fungus. In this case, you will have to wait until the surface is completely dry before proceeding with further work.

Ceresit CT 16 primer application technique

After opening the container with the primer, the composition is thoroughly mixed, then poured into portioned containers, if necessary, then proceed to application.

The layer is thinned and as uniform as possible using suitable tools. On a wide, even surface they work with a roller and a wide brush, in corners and hard-to-reach places use a gun and a brush.

Drying time

A thin coat of primer, applied in accordance with technical specifications, dries in 3 hours. If the room is too humid or cold, the drying period may take 5-6 hours.

Possible errors

After painting, errors are immediately visible. At the seed stage, crafters and beginners make typical mistakes:

• Priming a dusty surface. If you do not clean the walls and ceilings before starting work, the layer will crumble along with the paint under the weight of the materials.
• Work on the surface without waiting for complete drying. Primer ST-16 dries from 3 to 6 hours. Before proceeding with the work, the wall should be checked for “feel”.
• Addition of solvents and other auxiliary fluids. Primer ST-16 is already ready for use, therefore the introduction of additional components will harm and worsen the adhesion properties.
• Application of a thick layer. Manufacturers remind that the primer should be applied in a thin layer - this is one of the rules of work. A thick layer of material will cause delamination and compromise the vapor permeability of the coating.

When working with a primer, it is important to follow the basic requirements in order to achieve a good finish after finishing. If the primer is done incorrectly, the adhesion to decorative materials will deteriorate, there will be a risk of peeling and falling paint after the final finish.

Security measures

When working with primers, the usual safety rules are observed. Masks, goggles and gloves are used to protect the face and hands. To protect clothes, aprons, cuffs or special capes are selected. Primer ST-16 does not contain toxic substances, therefore it is not necessary to ventilate the room during work, although it is necessary to ensure good ventilation during repairs in any case.

Recommendations from the masters

The main requirement when working with primers is the correct surface preparation. Failure to complete work prior to priming may result in complete delamination of all applied materials.

The masters recommend observing the following rules:

• use quality tools;
• properly prepare the surface;
• avoid an abundance of smudging during direct application;
• do not use small brushes that leave hairs.

Do not rush to apply decorative materials.If the surface does not dry well, you cannot work.

Analogs

St-16 from the manufacturer "Ceresit" can be replaced by other similar compositions:

• Universal remedy for Bergauf Primer. It is a primer designed to work on vertical and horizontal surfaces. The main difference with ST-16 is better grip with dry mixes. Otherwise, both compositions are similar and can be used for interior or exterior decoration.
• Primer antifreeze from "Knauf Multigrund" F. A universal mixture designed to work at low temperatures, it is applied to surfaces at -40 degrees. It works well on concrete or porous surfaces.
• Parade G100 Putzgrund adhesive primer. The difference between soil and St-16 is in the form of rejection. This composition is available only in 2.5 liter buckets. Moreover, there are almost no differences. Both compositions are intended for application on concrete or wooden surfaces, suitable for use in combination with all paint and varnish materials.

Since ST-16 belongs to the category of universal compounds, it has many analogues.You should choose a mixture of similar composition and basic properties, which will extend the life of the created coating, protect it from moisture and strengthen the layers.
