Polyurethane foam is a versatile building material that is excellent for finishing works of any category and degree of complexity. Its main purpose is sealing seams, insulating, fastening various objects, as well as fixing plastic doors and windows.

Varieties

Polyurethane foam is of two types:

• professional (you need a special separate sprayer for use);
• semi-professional or household (with a special built-in spray).

It is also divided according to the indicators of resistance to negative weather conditions:

• winter (use is allowed even at subzero temperatures);
• summer (can be used exclusively in the warm season);
• all-season (suitable for work at any time of the year, regardless of weather conditions).

Peculiarities

When choosing foam for installation, it is necessary to take into account the quality of the material. In this case, you need to carefully compare the expensive and cheap options. Usually, in expensive copies, the cylinder is much heavier in weight than the cheap one. Also, the economical option shows poor performance in terms of sealant resistance. After curing, professional foam is characterized by small and uniform cells, while household foam has a larger and more bumpy cell structure. Professional polyurethane foam is deservedly more expensive due to better quality, larger cylinder volume and technical characteristics.

Household polyurethane foam is a balloon with a special plastic tube that comes with the tool itself. To start working with such material, you just need to connect the tube to the built-in valve and press gently to get the required amount of foam. This method is suitable even for those who have never encountered a similar tool before. To fill small gaps or holes in the wall, it is enough to purchase a can of household foam.

As for more serious tasks, such as fixing a window sill or a door block, you need to buy a special professional foam for installation, which will perfectly cope with the above tasks.

The professional foam cylinder has a special thread onto which a gun equipped with a dispenser is screwed. This tool makes it possible to distribute the sealant as accurately as possible to the work area. Typically, there is enough foam for a large amount of work. The material is consumed sparingly, which cannot be said about household polyurethane foam, which tends to run out very quickly in the cylinder. In addition, unused semi-professional sealant can be safely thrown away, even if more than half of the material remains in the bottle, because after several hours in the open form, it hardens inside and cannot be used further.

The professional foam canister is reusable . The dispensing gun and cylinder valve can be flushed with a special solvent and continue to work with the agent at a different time. This advantage allows you to evenly distribute the workflow. It is much more convenient to use the dispenser, because with the help of a pistol you can get a uniform stream of foam, which will not contain an excess amount of the product. For example, to fix a plastic window, you need to use only one cylinder of professional foam, taking into account the use of a special gun. Using household polyurethane foam, you will have to spend three cylinders at once.

A high-quality pistol with a dispenser fully pays for its costs if there is a lot of work and an ordinary bottle of household foam is simply not enough.

Packaging

The products are packed in cylinders that meet the requirements of GOST. On average, the volume of polyurethane foam is from 300 to 850 ml, there are also large packages of 1000 ml. Foam cylinders are under high pressure and must be handled safely.

Brands

Currently, there is a large selection of foam manufacturers on the market. Let's consider briefly the most popular modern brands.

Technonikol 65

Professional means "TechnoNIKOL 65" is used for fixing walls, metal sheets, insulation of doors and windows. This material is considered to be all-season, as it can be used in various temperature ranges, ranging from –10 to + 35ºC. This feature makes this foam one of the most demanded building materials on the market. "TechnoNIKOL 65" has an increased output of the product. Its high performance and yield up to 70 liters are key benefits.

TechnoNicol Imperial

TechnoNIKOL Imperial is also a professional product, which is a polyurethane material in a bottle with a plastic thread. A special dispenser gun is attached to the cylinder, which carries out a moderate consumption of funds and is used for many finishing works. "Imperial" has a high capacity for filling cracks and holes.

Stayer

Stayer is a versatile polyurethane foam that is used to anchor window and door blocks, to fill voids and seams. It has excellent technical characteristics that ensure the strength of the sealant for a long service life, and also allow the material to be used both in warm and cold seasons. It can withstand temperature loads from –10 to + 35ºC.

Stayer sealant has good thermal insulation, is non-toxic in operation and has an increased amount of material, which makes it in demand for most serious construction and finishing work.

Bostik

Bostik is a product that is suitable for general use as well as for work with fire-resistant structures. It provides reliable adhesion of working surfaces, which is why it is used even in shipbuilding. Bostik sealant is simple to work with and cures easily when exposed to materials and air. The temperature range of foam application is from +5 to + 30ºC.

Moment

Moment is a material that has excellent resistance to temperature changes from –55 to + 90ºC. Such excellent performance makes the product popular among many construction companies. It is chosen for joining joints, pipe passages, thermal insulation of door and window blocks.

The "moment" is quickly distributed over the working surface and has excellent void filling ability. The cylinder is equipped with a special valve, which is required for the use and attachment of a separate dispensing gun. When working with the product, there is a faint odor that disappears on its own in the hardened form of the material. The foam-cured surface dries in about 10-15 minutes. This foam solidifies completely on average per day.
