Description of the sealants "Stez-a" and "Stez-b"

Stez-a sealant has been a part of the building product industry for over 20 years. Sazi CJSC, its manufacturer, creates a vast array of adhesives, compounds, and sealing compositions. The product is made in compliance with GOST 30971, and it can be applied with ease to a variety of surfaces, even those with restricted access. The sealant becomes a durable, white, waterproof seam upon polymerization. Furthermore, the material is produced in shades of brown, light gray, and dark gray. Other pigments can be added to it upon the customer’s request.

Acrylic serves as the basis for Stez-a, a one-component composition. This is a pasty, viscous plastic mass that staggers while maintaining its elasticity. The sealant’s primary ingredient, an acrylate mixture, has strong strength qualities and potent protective qualities.

The product’s outstanding polymer adherence is its key characteristic, making plastic window installation and repair its primary application. The following are some uses for sealant, among others:

• sealing of any street seams: cracks, voids in metal, wood, concrete;
• strengthening the outer layers of installation joints;
• repair of buildings of residential, office, administrative, industrial purposes;
• insulation of cracks when fastening the balcony mechanisms;
• restoration of cracks in buildings;
• protection of mounting foam from damp, ultraviolet and moisture on different surfaces;
• Fixing stained glass.

Steiz-B sealant, which is intended to handle internal seams, may be a preferable option in certain situations rather than this remedy. This is a one-component vapor barrier composition that can be used in any type of building to place windows and balconies. The tool is characterized by excellent adhesion with a variety of materials, vapor barrier capabilities, resistance to deformations, and a long service life. Both sealants come in solid and soft cartridges with capacities of 310 and 600 ml, as well as plastic buckets weighing 3 and 7 kg.

Technical characteristics and composition

The "Stez-a" sealant’s primary functional properties are derived from its "acrylic copolymers" core. Foamers, ammonia, thickeners, plasticizers, and elastomers are also present in the product. Antiseptic additives in the composition stop bacteria and fungi from reproducing.

It doesn’t need to be mixed or hardened before application; the sealant is realized in its final form. The composition’s primary characteristics and technical specifications are:

• Tixotropic (does not flow from vertical bases);
• suitability for most building materials (brick, plastic, concrete, plaster, aluminum, PVC, foam concrete, wood);
• resistance not only to static loads, but also to vibration, deformation and shifts;
• vapor permeability, the ability to remove condensate;
• shrinkage in minimal limits (not more than 20%);
• Stretching to rupture of at least 250%;
• the formation of the primary film in 2 hours;
• the period to complete polymerization – 48 hours;
• The service life of the sealing seam is 20 years;
• temperature when applying – from –10 to +35 degrees;
• The temperature during operation is from –60 to +80 degrees;
• the possibility of freezing and storage of the composition up to 30 days.

It is possible to apply a sealant even on a damp base, which is crucial for street work. The seam will have a matte appearance after curing and will become instantly resistant to atmospheric factors and UV radiation. The sealant layer may need to be plastered or painted.

Advantages and disadvantages

Due to its high degree of adhesion, Stez-a consistently adheres to materials without rotting or causing corrosion. Because of its extremely high vapor permeability, it prevents the room’s microclimate from being disturbed and prevents the growth of mold and fungus, which occur when a home is overly humid.

Additional benefits of the arrangement:

• simplicity of work – even a beginner will cope;
• lack of need for components;
• the ability to apply to inclined, vertical, horizontal joints;
• exclusion of damage under the influence of atmospheric factors for many years;
• extensive color line;
• tolerance of mechanical damage;
• strict compliance with GOST;
• frost resistance, suitability for harsh climate;
• small shrinkage;
• excellent plasticity;
• the possibility of coating LKM after drying;
• 100%quality guarantee from the manufacturer.

One of the drawbacks is that the product has a limited shelf life; even if the packaging is sealed, it will need to be thrown away after a year. Since the product’s elasticity isn’t as high as silicone sealants’, it’s best to use alternative compounds on newly constructed buildings that are prone to shrinking. After drying, the sealant "Stez-a" is still porous, so it should only be used in extreme circumstances for internal work. In most cases, "Stez-B" is a better option. If not, there’s a chance of significant fume absorption, seam darkening, and property loss.

Application rules

It is best to seal joints, such as windows, during dry weather. The sealant needs to be heated to +18 degrees (withstand in a heated room) if the street is below freezing. Diluting the sealant with water is strictly forbidden as this will reduce its elasticity and other functional properties. Make sure the window block boxes are securely fastened with mounting foam or another method to produce a dependable and long-lasting seam.

To ensure an exact joint, glue the edges of the future seam with painting tape beforehand. Use a mounting gun to apply a sealant; this requires prior preparation. The most comfortable narrow spatula or small brush is to exhaust the seam. In addition, a spatula is gathered and used, and it is put to use in plastic pails.

• Excess foam is cut off with a sharp construction knife (the permissible pore size in the foam should not exceed 5–7 mm);
• rub the base from dust, dirt;
• apply a sealant in a strip in the depths of the junction, avoiding gaps;
• For 10–20 minutes, leveled the layer with a spatula;
• They immediately remove the painting tape until the seam is seized (if the tape is not glued, then the excess is simply wiped with a rag);
• wait until it dries for at least 48 hours, then stain the seam, if it is required.

Material consumption

About 70–80 g of sealant will be used on one linear meter for a sealant joint with a width of 15–20 mm (standard size) and a thickness of 2 mm. The consumption will rise in response to these parameter increases.

In order to achieve long-lasting and superior finishes in paintwork projects, sealants "Stez-a," "Stez-B," and "Stez-D" are indispensable products. Whether you’re working with plastic, wood, or metal surfaces, each type of sealant has special qualities appropriate for a variety of applications. The unique benefits of each composition will be broken down in this article, along with instructions on how to use them correctly to guarantee the best possible adhesion, durability, and protection for your painted surfaces.

Storage recommendations

The sealant may freeze and thaw multiple times (up to ten cycles) while being stored. Throughout the year, the composition is kept in closed containers at a temperature of –5. It is best to use the sealant right away after opening because it can dry out.

If it is not possible to apply the remedy simultaneously, there are several ways to keep the remedy intact in the tube. One of them is as follows:

1. Press the composition so that the upper part of the tube is empty.
2. Extract the piston, melt plastic and press with plots to seal the upper part of the package.
3. Put hermetically sealed containers for storage in a cool place.

Alternatively, transfer the sealer into a glass jar, making sure to leave as little air space as possible on top. Once the jar has been rolled under the iron cover, store it somewhere that isn’t exposed to sunlight.

Is it possible to use Stez-B instead of “Stez-a” and vice versa

These are not transferable funds. Since "Stez-a" is vapor permeable, moisture can easily escape the seams. In contrast, Stez-B effectively seals the internal joints by preventing water from penetrating the space. It is preferable to use both of the kit’s funds in tandem.
