Today, when performing many types of construction work, it is already quite difficult to do without foam. It is sometimes even impossible to improve sound and waterproofing, to seal joints without using this substance. But at the same time, the result depends on the quality of the foaming mixture, therefore, its choice should be approached very seriously.
There are many brands and types of foam mixtures for installation, but not all of them can guarantee a high-quality result. Among the materials that have proven themselves from the best side are Penosil polyurethane foam, produced by the Krimelte company (Estonia). This substance is white or cream in color, completely odorless.
Features
Using a sealant of this brand, it is possible to fill cavities of various types and sizes, to fix building structures. Despite the fact that the material is not widely advertised in the media, it surpasses many more well-known brands in the volume of the mixture released from the can.
Professional builders note the following features of the use of the foam substance:
- It is best to use all-weather brands indoors, since at low temperatures manipulations with them are somewhat difficult.
- When using mixtures of winter options in the premises, a slight primary expansion is observed. But in the cold, the material behaves perfectly.
- Polyurethane foam "Penosil Gold Gun" differs in the increased exit of material.
- If the temperature of the surfaces intended for processing is above 30-35 ° C, the material does not foam well or even drains. To fix the problem, it is necessary to shade the area with the design intended for processing.
- 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 preserves its initial properties at temperatures from -45 to +90 ° C.
- Excellent moisture resistance.
- Low heat conductivity.
- Quick setting. Penosil polyurethane foam completely hardens in 10 minutes - 24 hours (the exact figure depends on the type of foam).
- High adhesion to the surfaces of many types of materials. It can be wood, plastic, polymer compositions, stone, metal.
- The combination of elasticity and ductility. Thanks to this, it is possible to fill all the cracks as much as possible and subsequently avoid gaps.
Types of material
The company produces three lines of materials of this kind:
- Gold Series. Polyurethane foam "Penosil Gold" is intended for professional use. Used in carrying out capital work. This is construction or repair work in residential buildings, installation manipulations at industrial facilities.
- Standart Series. Sealant for professional and domestic use. Available in several versions - all-weather, summer and winter.
- Premium Series. Means are universal, it is good to work with them in any weather conditions.
Foam application
If professionals know how to handle foamy substances, then home craftsmen who have not yet had to deal with this material may not know some of the features of its use. To ensure that the procedure is not complicated, the following rules must be considered:
- The surfaces to be bonded or sealed must be pre-cleaned to remove dust and dirt.
- Hands should be protected with gloves - Penosil polyurethane foam does not wash off well, and in sensitive people it can cause allergic reactions.
- Before work, it is necessary to study the manufacturer's recommendations, which are indicated on the spray can.
- Attach the cylinder to the gun.
- Place it so that the jet is directed to the desired area. The space needs to be filled by one third.
- To speed up the process, you can sprinkle water on top of the mass, due to which polymerization will occur faster.
- Wait about half an hour and make sure that 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, builders have to work with the material. What do professional workers think about Penosil? Foam mounting reviews is only positive. They emphasize that:
- the material always has excellent quality;
- the structure of the mixture is uniform;
- if secondary expansion is observed, then its indicators are very low - 6-10%;
- no shrinkage;
- working with the material is easy.
Volume and cost of foam
Polyurethane foam is available in several standard forms. One of the differences is the volume, due to which you can get the amount of foam needed to solve a specific problem. What is the volume of Penosil polyurethane foam in standard cylinders?
Several options are available:
- 300 ml From a cylinder of such a capacity at the outlet, a finished substance of approximately 30 liters is obtained.
- 500 ml The tank delivers almost 40 L of ready-to-use foam.
- 750 ml. The output is 50 liters.
- 1000 ml. Since cylinders of this capacity produce about 90-100 liters of mounting foam, they are used where large-scale tasks are needed.
It is depending on the volume and foam for installation is selected "Penosil". The price again depends on the capacity of the container, 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.
