Today, when performing many types of construction work, it is already quite difficult to do without polyurethane foam. It is sometimes even impossible to improve sound and waterproofing, seal seams without the use of this substance. But at the same time, the result depends on the quality of the foaming mixture, so its choice should be approached very seriously.
There are many brands and types of foam mixes for installation, but not all of them can guarantee a quality result. Among the materials that have proven themselves from the best side is the Penosil polyurethane foam, produced by the Krimelte company (Estonia). It is a white or cream-colored substance that is completely odorless.
Features
Using this brand of sealant, you can fill cavities of various types and sizes, fix building structures. Despite the fact that the material is not widely advertised in the media, it surpasses many more well-known brands in terms of the volume of the mixture released from the can.
Professional builders note the following features of the use of foam:
- Use all-season stamps best insiderooms, because at low temperatures, manipulation with them is somewhat difficult.
- When using mixtures of winter options indoors, there is a slight initial expansion. But in the cold, the material behaves perfectly.
- Foam mounting "Penosil Gold Gan" is characterized by an increased yield of material.
- If the temperature of the surfaces to be processed is above 30-35 °C, the material does not foam well or even drains. To fix the problem, you need to shade the area with the structure to be processed.
- In wet areas, the mass begins to bubble.
Sealant Properties
It is the characteristics of the material that ensure its high performance. These are:
- Atoxicity. After the polymerization process is completed, the material does not emit any harmful substances.
- Heat resistance. The sealant retains its original properties at temperatures from -45 to +90 ° С.
- Excellent moisture resistance.
- Low heat conduction.
- Quick setting. Foam "Penosil" completely hardens in 10 minutes - 24 hours (the exact figure depends on the type of foam).
- High adhesion to many kinds of material surfaces. It can be wood, plastic, polymer compositions, stone, metal.
- Combination of elasticity and plasticity. Thanks to this, it is possible to fill all the gaps as much as possible and subsequently avoid gaps.
Types of material
The company produces three lines of materials of this kind:
- Gold series. Mounting foam "Penosil Gold" is intended for professional use. It is used during capital works. This is construction or repair work in residential buildings, installation manipulations at industrial facilities.
- Standard series. Sealant designed for professional and domestic use. Available in several versions - all-season, summer and winter.
- Premium Series. The products are versatile and work well in all weather conditions.
Application of foam
While professionals know how to handle foam materials, home craftsmen who have not yet de alt with this material may not know some of the features of its use. So that the procedure does not turn out to be complicated, the following rules must be taken into account:
- The surfaces to be joined or sealed must first be cleaned to remove dust and dirt.
- Hands must be protected with gloves - the foam "Penosil" is poorly washed off, and in sensitive people it can cause allergic reactions.
- Before work, you must study the manufacturer's recommendations, which are indicated on the can.
- Connect the cylinder to the gun.
- Place it so that the jet is directed to the desired area. The space needs to be filled one-third.
- To speed upprocess, you can sprinkle water on top of the mass, so that polymerization will occur faster.
- Wait about half an hour and make sure the mass has expanded completely. If it is not enough to fill the seam, you need to add a little more mixture.
- After complete solidification (in a day), cut off the excess with a sharp knife and align the seams.
Consumer Opinion
Most often it is the builders who have to work with the material. What do professional workers think about Penosil? Mounting foam reviews are only positive. They emphasize that:
- material is always of excellent quality;
- uniform mixture structure;
- if there is a secondary expansion, its indicators are very low - 6-10%;
- no shrinkage;
- material is easy to work with.
Foam volume and cost
Mounting foam is available in several standard forms. One of the differences is the volume, thanks to which you can purchase the amount of foam needed to solve a specific problem. What is the volume of foam "Penosil" in standard cylinders?
Several variants available:
- 300 ml. From a cylinder of such a capacity, a finished substance of approximately 30 liters is obtained at the output.
- 500 ml. The container delivers nearly 40 liters of ready-to-use foam.
- 750 ml. Yield - 50 l.
- 1000 ml. Since cylinders of such a capacity give about 90-100 liters of mounting foam, they are used wherelarge-scale tasks must be tackled.
It is precisely depending on the volume that the Foam mounting foam "Penosil" is selected for work. The price again depends on the capacity of the cylinder, and also on the type of substance. For example, a mixture of the Premium Foam series with a volume of 500 ml will cost 210-250 rubles, 350 ml - 180-190 rubles.
