Characteristics of TechnoNICOL sealant No. 45

Poor sealing of external joints is the main cause of dampness, floor swelling and wallpaper peeling. It is quite simple to fix such a problem with the help of a sealing compound. The best qualities are possessed by rubber-based mixtures.

Sealant "TechnoNICOL" No. 45 can be safely attributed to the market leaders.

A mixture based on butyl rubber with fillers, targeted additives and an organic solvent. Butyl rubber is a polymer with a complex molecular structure. Due to this, it is highly resistant to various types of influences. He is not afraid of acids, alkalis and salts. It is insoluble in ethyl alcohol and acetone. Low gas permeability.

The mass itself is homogeneous, viscoelastic and mobile. The color of the mixture can be gray or white. The latter allows painting with facade paints. Test color and adhesion on an inconspicuous area before painting.

Butyl rubber sealant must perform the functions assigned to it with high quality due to its properties:

• elasticity;
• does not require additional preparations for use;
• deformation and strength indicators are at a fairly high level;
• high level of adhesion to various surfaces;
• operating temperature from -20 to +40 degrees Celsius;

• resistance to aggressive environment and precipitation;
• does not require special skills and tools for installation;
• subsequent staining is possible.

Specifications:

• the weight of one cubic meter of the composition is 800-1100 kg;
• able to withstand pressure up to two atmospheres;
• when trying to break the frozen composition, it is lengthened twice;
• the dry matter content relative to the total mass is more than 50 percent;
• the strength of the bond to concrete is two atmospheres;

• consumption per 1 sq. m from 0.5 to 1 kg of sealant;
• after application, withstands temperatures from -50 to +80 degrees Celsius;
• one hour for tack-free drying.

For all its advantages, TechnoNICOL # 45 sealant also has a disadvantage. It is for outdoor use only.

You can purchase butyl rubber sealant at your hardware store. In production, it is poured into 8 and 16 kg metal eurobeds.

The shelf life is 18 months. Be sure to pay attention to it. A mixture with an approaching and expired shelf life has the worst quality characteristics.

The price varies depending on the color and weight. So, for one kilogram of a white solution, you will need to pay around 195 rubles, and for a gray one already 189. For a sixteen-kilogram bucket, you will need to pay 3111 and 3036 rubles, respectively.

Store containers with sealant in a dry place with good ventilation and protection from sunlight.

As mentioned earlier, the sealant has an extremely high degree of adhesion to a variety of surfaces.

• concrete;
• metals;
• polymeric materials;
• glass;

• building blocks;
• wood.

Therefore, the range of its application is wide enough.

• concrete seams;
• reinforced concrete seams;
• metal constructions;

• window and doorways;
• balcony blocks;
• residential and public buildings.

• concrete;
• reinforced concrete;
• metal.

There are several types of applying TechnoNICOL No. 45 sealant to the surface:

• the entire surface is treated with the composition;
• the sealant is applied to the corners and the central part of the thermoplate on the side that will be attached to the surface;

• strips from 4 cm wide, there should be more than four of them per square meter;
• drops are also applied with a spatula, 50-80 g each, with a frequency of 10 per square meter.

The application method depends on the material of the surface, as well as on which method of applying the sealant is more convenient for you.

• it is recommended to mix the composition before starting work;
• dust and moisture can impair the adhesion of the sealant to the surface, so the surface must be cleaned and dried;
• if the work is planned to be carried out at subzero temperatures, then the sealant should be kept in a warm room for at least a day;

• the composition should be applied with a rubber or metal spatula;
• clothes, exposed skin, eyes should be protected from the mixture, be sure to use gloves;
• adding a solvent to the sealant for easier application will negatively affect its properties;

• watch out for the formation of gaps and voids during operation, they will negatively affect operation;
• always adhere to the manufacturer's recommended standards as described on the label.

Unlike analogues, this sealant can be used at low temperatures and high humidity.
