Stiz a: the whole truth about sealant

Storage advice

Mixtures in a closed container must be stored at a temperature not lower than -5 C. The permissible number of freezing / defrosting cycles is no more than 10. It is advisable to use the opened package immediately. If there is a large amount of sealant left, you can save it for future use in one of the following ways:

Make sure that the remains of the sealant are located in the middle part of the tube, then remove the piston. Fuse the ends of the plastic container and press firmly with pliers so that an airtight container is obtained.

Prepare a glass jar close in volume to the amount of remaining sealant and a metal lid with a rubber gasket. Transfer the mixture to a container

It is important that the air gap is minimal or absent altogether. This will prevent the mixture from oxidizing and changing its properties.

Roll up the jar with a lid in the same way as homemade preparations. Store in a cool, dark place.

Stiz sealants significantly improve the quality of assembly joints when installing window and door structures, and can also be used to seal interpanel joints and restore walls.

A paste-like composition based on latex polymers is completely ready to use. Sealants have high adhesion properties to basic building materials. After curing, they form a rubber-like protective layer that is resistant to moisture, weather conditions, and ultraviolet radiation.

The joints filled with mixtures have a long service life even in extreme weather conditions. The compositions can be used for restoration and finishing works in almost all climatic zones.

Taking into account the extensive list of advantages (high physical and mechanical characteristics, convenient form of release, ease of use, long service life of structures), Stiz sealants are distinguished by an affordable price. In most cases, their use is economically feasible and profitable.

Peculiarities

Sealant "Stiz-A" is a product of the domestic company SAZI, which has been supplying this material for 20 years and has earned recognition among construction professionals. The composition is one-component, it is made on the basis of acrylic and is distinguished by its durability and high strength. Visually, the sealant looks like a viscous thick paste. Over time, it hardens, retaining its elasticity and strength. At the same time, high protective properties of this composition are noted. The color line includes several tones, but most often when installing windows, a white composition is used.

Acrylate composition "Stiz-A" has good adhesion to various types of polymers, due to which it is indispensable when working with plastic windows. And also the material is used for outdoor repairs, it perfectly seals street seams and joints, can be used when working with concrete, wood and metal bases. When installing windows, specialists seal the joints with this tool, both inside and outside. The presence of antibacterial additives in the sealant helps to protect the treated surface from mold and mildew.The manufacturer packs its products in containers of 310 and 600 milliliters. If serious work is ahead, you can purchase sealant in plastic buckets. Their volume can be 3 and 7 kilograms.

Using window sealants

A quality sealant should have the following properties:

• Strength;
• Long service life;
• Elasticity;
• Ability to cope with exposure to moisture, ultraviolet rays, temperature extremes and reactive chemicals;
• Ability not to drain from vertical surfaces under the influence of gravity.

All these qualities are possessed by Stiz A, Stiz B and Stiz D sealants. Work with their use must be performed in strict accordance with GOST. Previously, the place of application of the sealant is cleaned of dust, dirt and dried, after which it is applied to the surface.

Installation work in winter can be carried out at a temperature not lower than -25 degrees, and in summer not higher than +35 degrees. Otherwise, the seams and joints may be sealed poorly.

Sealants Stiz A and Stiz B protect the joints of plastic or wooden windows from wind and precipitation. Stise A is used to protect the outer seam. Stiz B is used to seal joints indoors.

A relatively recent novelty is the Stez D. sealant. Its main task is to protect the joints from moisture, which can saturate the walls of the house. A layer of this sealant is applied before the window is installed.

Sealant Stiz D has good moisture and vapor barrier properties and is recommended for use during installation work on the installation of windows.

Features of Stiz-A sealant

Stiz-A is a sealant designed specifically for plastic windows. It is a one-component, ready-to-use formulation immediately after purchase. It does not dilute or mix, but the finished product looks like a viscous mixture.

The sealant has been popular with professional craftsmen for 20 years. It gets good reviews for its properties and usability. It is made on the basis of acrylic, and after drying it retains high strength, at the same time with excellent elasticity. Good protective properties of this composition are also noted.

Sealant Stiz-A is presented in different colors, but when installing plastic windows, a white mixture is most often used. There are brown, different shades of gray, which allows you to choose the most suitable material for a particular job.

A sealant for working with plastic frames must meet a number of technical requirements:

• Good toughness.
• Sufficient elasticity.
• Ability to withstand humid environment, atmospheric conditions.
• Resistance to different temperatures, frost.
• Ability to firmly adhere to vertical surfaces.
• Long service life.

The sealing compound Stiz-A adheres perfectly to various types of polymer surfaces, therefore it is ideal for installing plastic windows. This composition is also good for outdoor work, when you need to insulate street joints. It also adheres to metal, wood, concrete surfaces. The antibacterial components in the Stiz-A sealant help to avoid the appearance of mold and mildew.

The products are available in containers of 310 and 600 ml, it is possible to purchase formulations in buckets when performing voluminous work. The latter can be 3 and 7 kg.

The main purpose of using acrylic is to protect the polyurethane foam. It was found that due to temperature fluctuations on the street, its volume decreases, from which the window frame ceases to be securely fixed and may move. This leads to damage to the locking elements, and also becomes a factor in the destruction of the plaster, which adheres to the window frame.

The foam is also negatively affected by precipitation and temperature extremes.

Peculiarities

Not allowed:

• applying a sealant to a surface with free moisture;
• dilution of the sealant;
• use of sealant in areas of prolonged contact with organic solvents and oils, with highly concentrated acids and alkalis;

• it is not allowed to use sealant on bases formed by bitumen and bitumen-polymer materials, including roll ones.

Application rules

When using a vapor-permeable acrylic sealant, you should know how to properly seal the cracks with it. Application is carried out with already installed PVC slopes. For work, you will need a basin of water, construction tape, a knife, spatula, sponge, rags or napkins. If the material is packed in a special bag (cartridge), then an assembly gun is needed.

Procedure:

• preparation of the coating provides for cutting of the polyurethane foam, its surface should be smooth, not have breaks and strong porosity (pore size is allowed up to 6 mm in diameter);
• the surface next to the foam is thoroughly cleaned of dirt and dust, sometimes it makes sense to use tape, at the end it is wiped with a damp cloth;
• masking tape can be used to paste over the areas adjacent to the gap, taking into account that the sealant will cover about 3 mm of the window frame and walls;

• the paste is squeezed out with a pistol into the cracks, while it is necessary to simultaneously smooth the seam, the layer thickness is from 3.5 to 5.5 mm, leveling can also be done with a spatula;
• the protruding layer is smoothed with a finger, wetting it in water, all the recesses must be filled to the end, the excess composition is removed with a wet sponge, trying not to deform the product layer;
• then the tape is removed, and after hardening, the seams are painted to match the walls or window frames.

Qualified craftsmen advise to carry out the work in small areas that can be processed immediately, because during polymerization it will already be difficult to correct errors.

Acetone must not be used to degrease coatings, which leaves streaks and unsightly stains. You can use gasoline or white spirit.

Sealing windows or other joints should be done only in dry weather. If the outside temperature is below zero, the sealant will have to be heated to 18 degrees (kept in a heated room). It is strictly forbidden to dilute the sealant with water - this will lead to a decrease in its elasticity and other operational properties. To create a reliable and durable seam, you need to make sure that the boxes of the window blocks are firmly fixed with foam or otherwise.

The edges of the future seam are pre-pasted with masking tape so that the joint is perfectly even. Sealant is applied using an assembly gun, which must be prepared in advance. It is most convenient to level the seam with a narrow spatula or a small brush. Also, a sealant is taken with a spatula and applied, which is sold in plastic buckets.

Work order:

• with a sharp construction knife, cut off excess foam (the allowable pore size in the foam should not exceed 5–7 mm);
• wipe the base from dust, dirt;
• apply the sealant in a strip to the depth of the joint, avoiding breaks;
• within 10–20 minutes the layer is leveled with a spatula;
• immediately remove the masking tape until the seam has seized (if the tape has not been glued, then simply wipe off the excess with a rag);
• wait until dry for at least 48 hours, then paint the seam, if required.

Types of sealants for windows, their features

There are many types of sealants, so let's try to figure out which sealant is best for PVC plastic windows. Below we will consider the main types of sealants that can be used to seal the cracks in plastic structures.

Silicone

It is a universal composition based on organosilicon compounds. It can be used both indoors and outdoors. Differs in elasticity, high adhesive properties, ease of application and affordable cost. Subdivided into acid and neutral types. When using an acidic sealant, a vinegar smell appears in the room, which subsequently disappears. Silicone does not shrink, does not lose its color and elasticity.

Acrylic

It is also elastic, in a liquid state it is washed off with water. It is mainly used for outdoor work, for sealing assembly joints, as it is resistant to ultraviolet light and atmospheric precipitation. For internal work, it is not used so widely, since the porous structure of the hardened sealant over time begins to absorb all kinds of fumes from the side of the dwelling and from this the sealed layer can gradually darken. It is recommended to paint it to prevent darkening. Acrylic sealant for plastic windows for the winter for external use has a low cost.

PVC based sealant (polymer)

Based on MS polymers. It is also called liquid plastic. Possesses excellent adhesion and viscosity. After sealing the cracks of plastic windows, it forms a single structure with this material. The only requirement for the use of this type of sealant is the absence of loads of any type on the seams, which can lead to rupture of the hardened material. For such a white polymer sealant for windows, the price is quite high, which comes from its high-tech properties.

Polyurethane sealant

This viscous material based on polyurethane polymers easily adheres to almost all materials, including PVC. After hardening, it can be painted or varnished.

Butyl sealant

They are made on the basis of polyisobutylene (a rubbery substance). It retains its elasticity and resilience in the temperature range from -55 to +100 degrees. UV resistant, harmless to others. It is used not only for sealing cracks, but also for repairing double-glazed windows, as it has a high vapor tightness.

Theokol sealant

Manufactured on the basis of polysulfide components.This composition allows the theokol window sealant to solidify regardless of the air temperature and humidity. It is indispensable for outdoor work. In practice, this means that such a composition can be used with confidence in winter, as well as in rainy weather.

Storage advice

During storage, it is allowed to freeze and thaw the sealant several times (no more than 10 cycles). In a closed container, the composition is stored at a temperature of -5 degrees throughout the year. After opening, it is advisable to immediately use a sealant, as it can dry out.

If a one-step application is not possible, there are a number of methods that will help preserve the remaining product in the tube. Here is one of them:

1. Press in the composition so that the upper part of the tube is empty.
2. Remove the piston, melt the plastic and press down with pliers to seal the top of the package.
3. Place the sealed container for storage in a cool place.

Window sealant in various packaging

You can also transfer the sealant to a glass jar, leaving as little air space as possible on top. After rolling up the jar under an iron lid, put it for storage in a place where there is no access to the rays of the sun.

Nuances of work

In order to maximally protect the seams from the penetration of cold, moisture and make them super strong, a certain thickness of the sealant is important - 3.5 mm. Since this is difficult to regulate, you should use a regular ruler with markings at the end. To do this, it is immersed in a layer of foam. You can determine the size of the layer by the remaining traces. After that, the damaged coating is additionally smoothed with a paste until it is completely leveled.

It should be noted that a smaller layer has a reduced quality, which affects the strength of the insulation.

Builders often use two sealants - "Stiz-A" and "Stiz-V", this also has a certain meaning. This is explained by the fact that for absolute security it is necessary to have both a reliable outer layer of an insulating substance and an inner one, which is provided by "Stiz-V". Unlike the A-grade sealant, due to which moisture in the foam is discharged outside, the B-grade sealant prevents steam and moisture from entering the room.

On the other hand, "Stiz-V" is not intended for outdoor use - as a result of application, the liquid entering the polyurethane foam accumulates in the seam, in addition, the thermal insulation properties of the construction foam are reduced. That is why Stiz-A is considered an ideal insulation tool for external joints.

According to the builders, with a large scope of work, it is wiser to use formulations with packaging in a polymer tube or file-package, since the increased cost is compensated by the speed of sealing with a pistol.

To learn how to install a window using a vapor-permeable sealant "Stiz-A", see the video below.

Application

Working with acrylic sealant does not require special skills. However, in order to obtain a high-quality result, you need to take into account some points. In order for the composition to adhere well to the surface, it must first be well cleaned and dried. The composition can be applied directly from the tube, by pressing, with a gun or with a spatula.

Pay attention to the joint depth before applying.

With a sufficient seam depth, it is recommended to first place a special cord or sealant in it. This will save the amount of sealant. After applying the composition, the surface is cleaned and degreased.

The main area of ​​application of the Stiz-A agent is the sealing of plastic windows. However, its use is not limited to this.

Stiz-A from SAZI can be used for such purposes as:

Insulation of cracks in wooden frames.

Filling voids in concrete, metal and wood structures.

Elimination of external cracks in the brick surface.

An acrylic sealant is used to protect the polyurethane foam from moisture. The sealant is frost-resistant and non-corrosive. It combines well with a wide variety of materials that are often used for window installation. Surfaces do not need to be primed before applying the Stiz-A composition.

The material stretches well, which is extremely important when filling joints in brick or wood masonry, as well as when insulating gaps between the window frame and openings
