Stiz-A Sealant: Technical Specifications and Applications

When installing windows, it is necessary to take care of insulation in a timely manner; in this situation, reliable sealing of seams and street joints is required. An excellent assistant is sealant Stiz-A. This composition has gained wide popularity among consumers. It does not need to be pre-diluted, but can be used immediately. Technical characteristics and positive feedback from consumers allow to call sealant the best material on the market today.

The sealant Stiz-A is a product of the domestic company SAZI, which has been supplying this material for 20 years and has won 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 bar includes several tones, but most often when installing windows the composition of white color is used.

Acrylate composition "Stiz-A" has good adhesion with various types of polymers, due to this, it is indispensable when working with plastic windows. As well as the material is used for exterior 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 using this tool both inside and outside. The presence of antibacterial additives in the composition of the sealant helps protect the treated surface from the occurrence of mold and mildew. The manufacturer packs its products in containers of 310 and 600 milliliters. If you are serious work, you can buy sealant in plastic buckets. Their volume can be 3 and 7 kilograms.

This product has its undeniable advantages, thanks to which it confidently holds a leading position in the modern market. First of all, it should be noted that it strictly complies with GOST. Also, the sealant has a high vapor permeability, can be used in conditions of high humidity, withstands temperature drops from -60 to +80 degrees, has frost resistance and can be used in regions with a harsh climate. The Stiz-A sealant is vapor-permeable, it adheres well to a large number of bases, among them plaster, metals, brick, plastic, concrete and others should be noted. Even if the coating is wet, it does not hurt to produce work without affecting the result.

Consumers note the excellent plasticity of the material, its slight shrinkage, which can be up to 20 percent., It is possible to coat the surface with paints after the sealant has completely hardened. In addition, the material is well tolerated by exposure to sunlight and ultraviolet radiation, resistant to mechanical loads. The primary film is formed in 2 hours.

The disadvantages of the sealant overlap with its merits. However, information about them is undoubtedly important. First of all, this product does not have a long shelf life. Even with unopened packaging, it ranges from 6 months to 1 year. Some note the lack of elasticity in comparison with silicone analogues. Since the sealant has a porous structure, its use for indoor work can cause some difficulties.

When using this acrylic composition you need to know how to properly and competently carry out the work. The first application is carried out on pre-fixed slopes. To work you will need components such as building tape, spatula, sponge, knife, piece of cloth and a basin of water.If the sealant has a special packaging, it will be necessary to use a mounting gun. First you need to prepare a coating. To do this, cut the mounting foam so that the base is smooth and minimally porous. The maximum pore diameter can be 6 millimeters.

All coatings must be thoroughly cleaned of dust and dirt, and also wiped clean. The surface around the joint is glued with masking tape to avoid contamination. The sealant is squeezed directly into the gap, and then smoothed. The layer should have a thickness of from 3.5 to 5.5 millimeters. It is best to use a spatula for leveling. It must be ensured that the slots are completely filled. Excess material should be carefully removed with a wet sponge.

After these steps, you should remove the mounting tape. When the sealant hardens completely, the seams can be painted. Professionals recommend not to process large areas at once, because the material is easier to process and correct deficiencies at a time when it did not have time to harden. When a sealant has been used previously, its residues should be carefully removed,otherwise, spots may appear on the surface over time. To degrease the coating, it is advisable to use white alcohol or gasoline. The use of acetone can cause problems, as it is able to leave spots and stains.

Hermetic Stiz-A can be applied in different ways. Use of the assembly gun or the pallet is possible. The temperature during the work should be from +25 to +35 degrees. The time required for complete solidification is two days. The average consumption of sealant per linear meter reaches 120 grams.

In order for the material to fully perform its functions, it is necessary to apply it correctly, observing the required layer thickness. If it is less than necessary, the quality of the insulation may decrease, which will affect the strength. There are situations when masters consider it optimal to use two sealing compounds at once - “Stiz-A” and “Stiz-B”. The second sealant ensures the reliability of the inner layer of insulation. It prevents the penetration of moisture and steam from the room. It should be borne in mind that Stiz-B is a material exclusively for internal use; it cannot be used for outdoor work.Experts advise when a large surface area is applied sealant brand "Stiz-A" using the mounting gun, which can reduce the time and improve its quality.
