How to use the mounting foam and prevent errors in your work?

Advantages and disadvantages of working with the material

Today both professional builders and domestic masters can not imagine the installation of windows and doors, as well as many other works without this useful material.Working with assembly foam is really very convenient, because it does not require the presence of additional mechanical devices or energy sources.

The advantages of this sealant is attributed its high sealing, installation, heat and sound insulation characteristics.It penetrates into all cracks and joints hard and fills them suitable for almost any building materials, be it concrete, bricks, glass, wood and so on.Using the foam repeatedly accelerates the process of sealing and installation work it is characterized by low labor intensity.

The disadvantage is the sealant reaction to ultraviolet light.Polyurethane foam can not tolerate sunlight.Before working with assembly foam, you need to wear gloves and goggles, and closed, poorly ventilated areas need to use a respirator, because the pair of drying foam irritate mucous membranes and skin.

Installation for repair - use foam

Polyurethane foam, instructions for use for that are always written on the back side of the balloon, it is flexible enough in the matter of conditions of use.If you observe some simple rules when working with it, the result will make you happy.All work is best done in warm time at temperatures between +5 and +30 ° C.

The higher the temperature and humidity, the faster and better the polymerization process takes place, that is hardening.Of course, there are reasonable limits, at temperatures above 30 degrees the foam will begin to behave unpredictably, most likely, the seam will become worthless.

Before mounting the foam used, it is necessary to shake the container well for a minute to the chemical components are mixed in the cylinder and its contents became homogeneous.Then you need to unscrew the cap on the tube to wind adapter and turn the bottle upside down.

ideal option, if available a special gun for applying foam.Not only does it reduce its consumption, but also much simplify the work.Such an approach works only when used sealing and assembly properties, for example, when installing windows and doors, sealing of gaps and joints, but that the possibility of applying the sealant does not end there.

gun with foam - comfort for insulation

One-component mounting polyurethane foam used as thermal insulation of buildings and at construction sites.Spray foam to insulate the surface is produced using a special air pistol.

His device and principle of operation is similar to gun for.The cylinder is screwed thereto as well as to a conventional gun, with a threaded adapter.By clicking on the bracket under the effect of the composition of one of its components becomes dispenser opening complicated valve mechanism.Head foaming liquid regulated gun.Special regulator on the injector determines the shape of the exhaust plume.

With the acquisition of skills and dexterity, you will understand how to apply the foam core, because when you work with it not have to be a highly qualified specialist.If, however, remains unclear, as the use of assembly foam, the video will explain obscure technical details.
