The main elements of the primer will be dissected in this section, along with an explanation of how each one affects its functionality.

Lastly, to get the desired result, the primer must be applied correctly. We’ll walk you through the entire application process, from surface preparation to primer application to drying periods. This guide, which includes 65 in-depth photos, attempts to make the procedure simple and understandable, even for people who have never used primers before.

Features of the primer Ceresit st-17

A special substance based on water is Article 17. It is completely transparent in the absence of additional pigments. The primer’s composition is characterized by the following elements:

• Olifa;
• Alkyd resins or other synthetic options.

Acrylic polymers combine to create a special kind of building material. It can be used even in rooms where people spend a lot of time because it doesn’t trigger allergic reactions.

Advantages of the primer Ceresit st-17

Because of qualities like these, Ceresitis Article 17 is a primer that is in high demand during construction projects.

• The ability to strengthen the surface, tie the dust particles present;
• Deep penetration of the primer into the surface that is subject to processing;
• Reduction of absorbent abilities of the base layer;
• Preservation of vapor permeability of the base material;
• The possibility of use in the zone where there is a heated screed;
• Protection of surfaces from mold, fungus and moisture. Builders-builders are unanimous in opinion-it is imperative.

The primed surface has a different color due to the presence of a yellow pigment; this makes processing much easier. The primer may be used for both internal and external projects.

One major benefit that many highlight is that Article 17 is environmentally friendly; it doesn’t negatively impact the environment in any way.

Universality is a plus

Ceresit CT 17 is a versatile primer that is frequently chosen for exterior use when painting fences, facades, and their insulation.

• At the same time, the procedure for insulation deserves maximum attention – in this case, the primer becomes protection against moisture and prevents the destruction of the insulation layer.
• Obviously, for work in the complex, the selection of different types of soils will be significantly complicated and will require additional costs – therefore, the best option would be to use the universal composition.

One such is Article 17. This material’s high degree of adhesion ensures the deepest penetration, giving the surface a robust and smooth finish.

Technical characteristics Ceresit st-17

The building materials market’s clear favorite is the trade brand Cerezite. The manufacturer offers a variety of soil options; the most well-liked ones are the ones that offer deep penetration and the so-called "winter" options.

With just a few minimal skills, you can work with this material at home and perform your own repairs.

When obtaining Article 17, you need to be aware of its primary attributes:

1. This primer is a water-polymer solution that does not smell. If, opening the packaging, the user even feels the light “aroma” of PVA glue, this should come across thought that the composition is a fake.
2. The use of the mixture is possible in the range from +5 to +35 ° C. If you plan to carry out facade work, it is necessary to purchase a “winter” option. Optimal working conditions with Article 17 – temperature about +20 ° C at a moisture content of 65%.
3. After applying, a primer layer is left for a while for a complete drying. Accelerating the process using air conditioners and other technical means is not recommended.
4. Storage Article 17 is carried out in indoor conditions, the composition must be used during the year. A small canister has a volume of 1 liter, the average – 5 liters, for processing significant surfaces it is better to purchase a primer in more significant containers of 10 liters. It should be noted that the primer must be used in the implementation of any repair work – this will definitely not be superfluous.

Cons of primer Ceresit st-17

There are several drawbacks to using the miracle compartment.

True, they don’t really matter that much:

• The product is difficult to remove from the surface if it is accidentally pouring at the time of work;
• In a situation where it is planned to apply a white decorative layer over the primer, the yellow pigment can “go out” – it is not always possible to paint over it;
• With large volumes, the use of the material may seem to some fairly expensive.

Considering the aforementioned, one could contend that using Article 17 has more benefits than disadvantages because its surface qualities are constantly enhanced.

Preparation of the base layer

The base must first be prepared for work by being cleaned of all types of pollution, including oils, fats, dust, bitumen, varnishes, and colors.

• The problem areas of the surface should be cleaned, defective should be removed and appropriate to repair.
• Malar coatings with a low level of adhesion should be completely eliminated, the seams should be sealed using putty.

Molar rollers

To stop their pollution, doors, windows, and other non-processing elements should be covered with a film.

Implementation of work

The following equipment will be needed for priming:

• Brush;
• Roller;
• Stick or mixer (construction);
• Bucket with water;
• Male.

Mixer Construction

There are several stages to the entire process:

1. Before use, the composition is well mixed using a construction mixer or stick in its absence.
2. The primer is poured into the tray – the required amount of the mixture is dials and distributed on the surface. It is required to create a thin, but uniform layer. Applying a primer, it is necessary to avoid the formation of a puddle on horizontal surfaces and fluxes on the walls.
3. Using a brush, hard -to -reach places are being worked out, including corners.
4. The surface is left without attention until complete drying. Typically, this requires about 5 hours. In a situation with porous surfaces, the period may increase to a day.

200 milliliters of primer are used on average per square meter. This indicator makes it simple to determine how much mixture will be needed to complete the repairs.

While utilizing Ceresit ST 17 primer, finishing material consumption is decreased and coating quality is greatly enhanced. Not only do "home masters" choose this material, but repair industry experts do as well.
