To close cracks and other gaps formed during construction, repair of various buildings, polyurethane foam is called upon. It also eliminates those shortcomings that were already inherent in specific walls, floors, ceilings and decorative elements, fills in the gaps when installing windows and doors. But in order to fully cope with such tasks, you need to carefully select the working substance.

Peculiarities

This brand of building materials has been in great demand among construction professionals for a long time. The reason is simple - it is distinguished by an unprecedentedly high quality of its composition.

The assortment of this brand includes the following compositions:

• products for household and professional use;
• foam cleaners;
• substances activating it;
• materials that have both a foamy and an adhesive effect;
• tapes to improve tightness;
• assembly pistols.

The brand is the property of the WolfGroup concern, more precisely, the Krimelte company that is part of it - a key manufacturer of sealing products on the European continent. Production facilities are located in the Russian Federation and the Baltic States, deliveries go not only to the post-Soviet space, but also to countries such as Japan, Israel, Germany, New Zealand. In total, polyurethane foam with this name goes to more than fifty different countries, which indirectly confirms its high perfection. Internal scientific and technical developments are actively underway, which helps to improve the main parameters from year to year.

Specifications

Penosil polyurethane foam is almost not advertised, but professional builders invariably make a choice in its favor. The amount of mixture that comes out when using one cylinder is greater than that of well-known competitors. How exactly this is achieved is a deep commercial secret. There are a number of universal brands in the assortment, but it is even more correct to use them for internal work, since negative temperatures have a bad effect on the result.

The foam is completely devoid of toxic properties and, after the end of polymerization, does not emit harmful substances.

Retention of consumer qualities is guaranteed in the temperature range from -45 to +90 degrees. A special formulation and manufacturing technology allows you to reduce the susceptibility to moisture, heat leakage and make the setting faster. Drying time ranges from 10 minutes to a day, depending on the selected variety and on the conditions for using such a composition.

Provides excellent adhesion to the following surfaces:

• tree;
• plastics and polymers;
• metal parts;
• stone.

The Penosil developers make every effort to combine elastic and plastic properties in their product, because for builders and repairmen it is important not only to fill the gaps, but also to eliminate breaks. The foam is almost odorless and produces an attractive white color that will delight any builder and home owner.

Models

Foam GoldGun 65 It differs not only in its intensive exit to the outside - when applied to a surface warmed up to more than 30 degrees, the quality of the mixture drops sharply, and bubbles begin to appear on wet structures. These are objective things, and it is necessary to fight against them, creating initially suitable conditions for work. The "Gold" line is completely professional, it is necessary for capital works at residential and industrial facilities. The "Standard" series includes foams of a mixed nature, the differences between them are reduced to different permissible temperatures. But the collection "Premium" is universal, its use does not depend on weather conditions.

Compound Gold gun winter designed for winter repair and can be applied calmly even at -18 degrees. Gold 65 and Gold Gun 65 All Season give a record level of foamy mass generation - an increase in productivity by 30% and 43%, respectively. Using Gold Gun Expansion All Season , it is easy to create even very delicate joints, since re-expansion is extremely small and does not harm the structures with which the builders work.

Premium Gunfoam - amateur foam for a wide range of construction work. Its cold modification can be used at temperatures down to -10 degrees. FireRated Gunfoam B1 - refractory type of foam, the flame resistance category of which meets the standards EN 1366-4 and DIN 4102-1.

How to use?

Those surfaces that need to be bonded or sealed are cleaned in advance: traces of dust and dirt are removed from them. It is very important to work only with protective gloves, because high adhesion will impair the removal of foam from the hands. Ideally, you should wear overalls or unnecessary household items. People suffering from allergies should be even more careful, since the slightest contact with the composition can lead to serious consequences.

Before starting work, you should always study the manufacturer's recommendations and in no case deviate from the requirements of the instructions.

The area where a gap, crack or chip has appeared is filled with foam by 1/3. Acceleration of polymerization is achieved by spraying the applied mass with water. If after 30 minutes the expansion of the foam is not enough, then only then it makes sense to add a new portion.

Reviews of the Penosil brand polyurethane foam are quite favorable. Builders and repairmen emphasize that the mixture is always of high quality and gives a uniform foam. The likelihood of secondary expansion is small, and if it occurs, then only in insignificant volumes. The company's technologists managed to achieve the absence of shrinkage.

With regard to the power achieved, the proportions are as follows:

• a 300 ml can gives 30 liters of foam;
• 500 ml corresponds to 40 liters of the mixture;
• Gunfoam B1 750 ml, when released to the outside, forms approximately 50 liters of foam;
• With the help of 1000 ml cylinders, up to 100 liters of active ingredient can be obtained, which is very important for large-scale work.

Before buying, it is recommended to find out what the viscosity of the foam used is - the level of adhesion to vertical surfaces depends on this.

Insufficiently viscous material will quickly slide off the wall and lose its valuable qualities. It is important to consider that even foams resistant to cold temperatures are best used in comfortable conditions , because the output of the mixture in this case from the cylinder of the same container will be the greatest. Household foam is equipped with a plastic nozzle and must be used in one go, while the professional version can only be applied with an assembly gun.
