Spray polyurethane foam : step by step instructions

Quality insulation can be done in different ways, but not all are suitable for complex surfaces.For example, the inclined or uneven plane vaulted underground storage, floor beams on the attic of the projections, and other cases.One of the most effective methods is spraying foam on the attic beams and various irregularities.Today it is easy to make your own with the help of a special device.

polyurethane foam - good thermal insulation

Warming spraying polyurethane foam - one of the most progressive methods of solving problems with insulation.High-quality surface treatment PUR (polyurethane) - a guarantee of saving fuel and energy resources.Method economically justify itself in 2-3 years, and in the harsh climate - for the year.Sami treated surfaces look very aesthetic - a bit like thick frost or snow wall.Foam for insulation:

• basement and attic;
• technical and commercial structures.

With the onset of warm season do not want to deal with insulation support facilities, however, it is better to do it now, in the comfort of weather conditions.To on uneven and sloping surfaces to obtain a uniform coating, require a one-time installation of polyurethane.This method of surface treatment simultaneously solve other problems, such as noise reduction, repelling insects and rodents.

This equipment is also designed to work at temperatures below freezing, but it is more convenient to make the application of foam to the desired surface in the summer, and rent (purchase) of the device will be cheaper.sprayed polyurethane foam processing may be used for interior and exterior surfaces of buildings of any plan:

• walls, roofs, floors;
• bumps, ledges, niches, ledges, etc .;
• any horizontal, vertical or inclined surfaces.

Compact equipment powerful enough for the application of polyurethane foam, although looks quite simple.It has been used successfully for the treatment of:

• garage door;
• inclined surfaces loggias;
• attic floor on beams;
• ceiling of the hangar or warehouse;
• underground buildings with stone vaulted ceilings;
• non-insulated walls extensions;
• storage facilities;
• Vans;
• basements non-residential premises;
• intermediate partitions;
• cabins workshops;
• heating main and external hot water pipe in the private sector.

Cured material strong and light, like a snowy foam.Foam filled gaseous substance consisting of Freon, carbon dioxide and normal air.That gaseous material structure guarantees him a minimum thermal conductivity, and porous structure provides sufficient sound insulation.It does not burn and does not change the structure of the cold.Ready polyurethane foam obtained by mixing the two components of the cylinders supplied with equipment for spraying polyurethane - through a gun nozzle.He is superior to mineral wool, and foam Penoizol in many respects.

master the working principle of this device is simple, if you have a general idea of ​​it.It is equally important to study in detail the attached instructions to the purchase, to avoid any problems during the operation.

Key Features spraying foam

Experts classify surface treatment using polyurethane foam spraying method as a kind of effective insulation sprayed Ecotermix.In modern construction, it is considered one of the most technological inventions of the XXI century.Interest accrues to the invention, and its effectiveness has no one no doubt.This technology continues to improve the application of the producers to offer the consumer an even more effective solutions to reduce the cost and production cost.

coating effectively prevents the penetration of excessive moisture in the room and the formation of condensation.This is very important in storage, and auxiliary premises, where it is recommended to maintain a low level of humidity.Among the most important characteristics of a high-tech sputtering worth noting:

• Excellent adhesion - adhesion of the composition to the surface to be treated without pre-treatment, ie, the "adhesion" to metal, concrete, wood (even with the remnants of the bark).
• PPU perfectly protects metal surfaces from rust and corrosion, as well as the damaging effects of various corrosive media.
• is possible warming of the surface, which can not be treated in another way - the wave slate, corrugated metal and a close-fitting netting.
• Outwardly frail surface treatment of foam manufacturers ensures a long service life - about 50 years, and even then the microgranules not lose insulating properties.

The main advantages of the method of spraying insulation

whole complex of works on high-quality polyurethane foam insulation sprayed, if the equipment can be performed independently for 1-3 days, depending on the size composition of the treatment.It is necessary to characterize the most important advantages of insulation spray technology:

• minimum thermal conductivity of hardened foam;
• completely eliminated all the cracks, seams and gaps;
• eliminated drafts, blowing snow and formation of cold bridges;
• spraying easily adheres to the most slippery surfaces and complex designs;
• composition does not react with extraneous chemical compounds;
• coating completely environmentally friendly, does not emit toxic fumes;
• surface treated effectively trapping heat;
• wonderful moisture and sound insulation;
• surface after curing does not crumble fairly stable, enables contact with the storage and other equipment;
• low coating weight gives an advantage to insulate the loft or attic;
• sufficient lifetime to warm the room.

Tip: Today, no other insulation can not be compared with sprayed polyurethane foam in its characteristics.However, it is sometimes confused with penoizol.Penoizol in its composition has a lot of water that remains inside the foam, reducing the insulating properties of the coating.It dries out and shrinks, may crack, so it can not be used in all conditions, in contrast to the foam.

Equipment for applying foam

Few people thought about whether you can make the spraying polyurethane foam with your hands?More often than not, learning about the possibilities of such processing, apply to the companies involved in this kind of insulation professionally.Professionals who have mastered the spray polyurethane foam high-tech equipment, hiring for applying insulation to your object.However, having mastered this method at home, you can open his office and to offer these services in order to have your business.The unit can be rented or purchased for production of valuable experience.If you want, you can invite a partner or companion - for the delivery of equipment to the auxiliary and improvised works.

providers offer two types of equipment - installation for professional spray foam and disposable devices used for self-use.It is important to do preliminary calculations, to know how much foam is required in the circumstances.Disposable device for spraying foam at home is much more economical than professional equipment, so it is simply discarded after use without waste or attempts to secondary use.Insulation is applied

thickness not exceeding 2.5 - 3 mm, which allows a single application, depending on the volume of cylinders, economically processed surface area of ​​from 15 to 95 sq.m.Equipment weight is large enough, but is designed for the transfer of one employee, but to the object you want to bet on the cars.To bring the installation into operation, special skills are not needed, it suffices to study the instructions.Allowed a pause in the application of the spray gun, and if the nozzle clogged, they are not required to clean, since there is provided a set of 5 - 10 interchangeable "nozzles".

Consider disposable packaging systems for polyurethane foam spraying the example Touch'n Seal Foam Kit 1000 LD:

• dimensions box: 32h32h49 cm;
• installation weighs 55 kg;
• 2-component kit (balloons A and 27.5 kg each);
• compact shape enables transportation in the trunk of passenger cars;
• foam hardens for a minute, expanding about 30 times;
• foundation equipment - tanks with components, the gun for mixing and spraying foam and 10 nozzles;
• 3-meter hose is sufficient to supply power to any surface;
• there is an instruction key for assembly parts, silicone grease and work gloves;
• volume cylinders designed 93 sq.m.2.3 cm at the surface of the foam;
• total volume of foam - 2.35 m³ density to 20 kg / m³;
• cutting part if necessary foam, it is available in 3 - 5 minutes;
• surface is completely hardened about 1 hour;
• after the first start-up may not work for more than 1 month;
• foam components have a shelf life of 1 year;
• cost of equipment - from 34500 rubles.

Where and how to purchase the equipment for spraying foam

Disposable unit for home use are available on the websites of officials involved in the supply of this equipment.For this need:

• contact the manager on the telephone number and place an order;
• pay for the installation of delivery by bank transfer card, urgent wire transfer or cash on delivery, depending on your circumstances;
• verify whether the delivery is included in the price and incurs an additional charge separately;
• after confirmation of payment equipment will be shipped from the warehouse and delivered to the specified address;
• delivery time - as in the regular mail, depending on the distance and transportation;
• all questions on the operation of the system for applying foam with your hands can be specified after the receipt on the same phone.

Features of the equipment

To start processing surfaces with polyurethane foam, they must be cleaned of dust and other fine suspension.Wash reagents and process is not necessary, simply carefully obmesti plane or vacuum.

to launch the equipment manual contains 10-12 items, but first you need to read the whole list to the end, to have a general idea about how to connect and setup process of applying the foam.

Important:

• watch not for the fact that results from processing of the planes from the sprinkler installation and the work of the master;
• adopt valuable experience on what movements ensured uniform application of foam;
• the most important in the learning process - to see how processed corners, bends, bumps, cracks and joints.

Tip: If you do not have prior experience, it is necessary to turn out in practice - no one teaches spraying a mixture of a uniform thin layer.However, if you work hard with a sure hand, the quality will be better than the unmanaged process, observing what happens in the end.Fix oversight is difficult, so it's better to start practicing on a remote vertical plane, and then foam the composition inclined, horizontal and irregular surfaces.

Warming spraying foam on the example of the balcony

Balcony - adjacent to the living room space, so good insulation is very important.Insulation polyurethane foam - one of the most effective methods of insulation.The feed mixture of the sprayer filling qualitatively invisible cracks and cavities through which the balcony or loggia gets damp and cold air.

process of insulation adjacent rooms is very simple.According to the instructions for installation:

• out of the box we obtain equipment;
• we connect hoses;
• shaken components;
• fasten the nozzle to spray;
• select the type of nozzle is determined by the specific goal (narrow or wide jet of foam feeding under pressure);
• pour foam on the first gap, then on the other handled the plane;
• excess amount of foam in some areas can be cut off after the initial hardening it.

Balcony insulation after treatment in a day can be brought to the final shape by any cladding material.

Note: The warmer on the balcony, the higher the temperature of the components supplied to the dispenser, the better foaming.When "warm" foaming flow components will be less and the damage layer looks a lot better, more magnificent.It is therefore recommended to operate at a temperature higher than 15 ° C.
