• Temperature mode. Foam is produced for use in summer (summer), winter (winter) or throughout the year (all-season).
• Method of application. Professional mounting material is used with a gun, and household,Equipped with an independent valve and direction tube.
• Flammability class. Foam can be flammable, refractory, or flame retardant.

The main difference between winter and summer foam is that in winter installation materials there are special additives that contribute to an increase in the rate of polymerisation of the composition at negative and zero temperatures.

Each type of mounting material has its own characteristics, its scope and composition. To understand exactly what type of foam is needed, it is necessary to familiarize yourself with the features of the main categories of Profflex materials.

Each type of Profflex foam has its own instructions for use, but also There is a list of rules that must be followed while using this material.

• It is necessary to use foam in accordance with the weather season. For summer - summer foam, for winter - winter.
• It is worth paying attention to the temperature of the cylinder with foam, which should be in the range from 18 to 20 degrees above zero. If the balloon is cold, then it is worth a little warm up. To do this, lower it into a container with hot water. Before use, the foam bottle is always shaken well.
• Before using the sealant, the surfaces to be coated with the composition should be thoroughly cleaned from dust, degreased and sprinkled with water, especially in summer.
• Work with the material should be in protective clothing.

• When using a cylinder of foam must be in a vertical position, and the filling of cracks, seams must be made by 70%, since the foam tends to expand. For large cracks, you should do a multi-layer filling - first the first layer, then drying is expected and the next layer is applied.
• Full polymerization of the material occurs during the day, and in winter, it may take a longer time. This should be considered during further construction work.
• When working with a sealant, it is easier to use a mounting gun than a tube that comes with the material.
• After full drying the remains are removed mechanically. For cutting, you can use a sharp knife or saw for metal.

If foam gets on your hands or clothes, then to remove it you need to use special solvents.

If you use the installation material, adhering to the basic rules, then it can be used to eliminate cracks and holes of any size, including ceiling defects.
