Polyurethane foam spraying: step-by-step instructions

High-quality insulation can be made by different methods, but not all of them are suitable for complex surfaces. For example, inclined or uneven planes, vaulted underground storage facilities, beams of overlaps on attic rooms, frequent protrusions and other cases. One of the most effective ways remains spraying polyurethane foam on attic beams and various irregularities. Today it is easy to do with the help of a special device.

Polyurene Foolder - Effective heat insulation

Hearth by spraying polyurethane foam is one of the most progressive methods for solving problems with thermal insulation. High-quality treatment of PPU surfaces (polyurethane foam) is a guarantee of fuel and energy resources. The method economically justifies itself in 2-3 years, and in conditions of harsh climate - for the year. The treated surfaces themselves look very aesthetically - something reminds of a dense yap or a snowy wall. PPU is suitable for insulation:

• basement and attic rooms;
• technical and commercial facilities.

With the onset of the warm season, I do not want to engage in the insulation of auxiliary premises, however, it is better to do it now, in comfortable weather conditions. In order for uneven and inclined surfaces, a uniform spraying is needed, a disposable polyurethane foam installation will be required. This method of treating surfaces is simply solved by other problems, such as noise insulation, intake scaring and rodents.

This equipment is designed to work at a negative temperature, but it is still more convenient to make polyurethane foam to the required surfaces in the summer, and rent (purchase) of the device will cost cheaper. Coating of polyurethane foam spraying can be used both for internal and external surfaces of structures of any plan:

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

Compact equipment for applying PPU is quite powerful, although it looks quite simple. It is successfully used for processing:

• garage gate;
• inclined surfaces of loggias;
• attic overlaps on beams;
• ceilings hangar or storage;
• underground buildings with stone vaulted ceilings;
• walls of disgraced attack;
• storage facilities;
• the surface of the vehicles;
• social floors of non-residential premises;
• intermediate partitions;
• cames of workshops;
• heat mains and external hot water pipes in the private sector.

The hardened material is durable and easy, similar to the snow foam. Foam is filled with a gaseous substance consisting of freon, carbon dioxide and ordinary air. It is the gaseous structure of the material that guarantees it the minimum thermal conductivity, and the porous structure gives sufficient sound insulation. It does not burn and does not change the structures in the cold. Ready polyurethane foam is obtained by mixing two components from cylinders supplied from polyurethane foam spraying equipment - by means of a gun with a nozzle. It exceeds mineral wool, foamizol and foam in many indicators.

Mastering the principle of operation of this device is easy if you have a general idea of \u200b\u200bit. Equally, it is not less important to study the instructions attached to the purchase so that there are no questions in the course of work.

Main characteristics of spraying PPU

Experts classify surface treatment with polyurethane foam by spraying as a kind of efficient emotermix sprayed isolation. In modern construction, it is rightfully considered one of the most technological inventions of the XXI century. The interest in the invention increases, and its effectiveness has no one for any doubt. This application technology continues to be improved by manufacturers to offer consumers even more efficient solutions and reduce cost costs.

The coating effectively prevents the penetration of excess moisture into the premises and formation of condensate. This is very important in those warehouse, auxiliary and office premises, where it is recommended to maintain a low level of humidity. Among the most important characteristics of a high-tech spraying should be noted:

• Excellent adhesion is the adhesion of the composition to the treated surface without preprocessing, that is, "clutch" with metal, concrete, wood (even with the remains of the bark).
• PPU perfectly protects the metal surfaces from the appearance of rust and corrosion, as well as the destructive effects of various aggressive environments.
• There is the possibility of insulation of those surfaces that are not processed by another way - wave slate, corrugated metal and grid tightness.
• Externally, the fragile surface treatment of PPU producers guarantees a long service life - about 50 years, and even after that, microgranules will not lose the thermal insulation properties.

The main advantages of insulation by spraying

The entire complex of works on the quality warming of the PPU, in the presence of equipment, can be performed independently for 1-3 days, depending on the processing area of \u200b\u200bthe composition. It is necessary to characterize the most important advantages of the insulation spraying technology:

• minimum thermal conductivity of hardened foam;
• all slots, joints and gaps are completely eliminated;
• drafts of the snow and the formation of cold bridges are eliminated;
• spraying easily sticks to the most slippery surfaces and complex structures;
• the composition does not react with outsided chemical compounds;
• the coating is completely environmentally friendly, does not highlight toxic evaporation;
• the treated surface effectively holds heat;
• beautiful moisture and sound insulation;
• the surface after the hole will not crumble, pretty resistant, allows you to touch with warehouse and other equipment;
• the low weight of the coating gives an advantage for the insulation of an attic or attic;
• a sufficient life of the insulated room.

Tip: Today, no other insulation can compare with the PPA sprayed in its characteristics. However, it is sometimes confused with foamizol. Penosole in its composition has a lot of water, which remains inside the foam for a long time, reducing the thermal insulation properties of the coating. He dries and gives a shrinkage, can crack, so it can not be used in all conditions, unlike polyurethane foam.

Equipment for applying PPU

Few people thought about whether it was possible to make a spraying of polyurethane foam with their own hands? Most often, learning about the possibilities of such treatment, they turn to the firms involved in the type of insulation professionally. Specialists who have mastered the spraying of PPU high-tech equipment are hired to apply insulation to its object. However, having mastered this method, you can open your office and offer data services to have your own business. Installation can be rented or purchased for the work of precious experience. If necessary, you can invite a partner or companion - to deliver equipment to objects and auxiliary workflows.

Suppliers offer two types of equipment - installation for professional spraying of PPU and disposable devices used for self-use. It is important to make preliminary calculations to know what amount of polyurethane foam will be needed in these conditions. Disposable installation for spraying PPU at home is much more economical than professional equipment, so it is simply emitted after use without disposal or attempts to recycled.

The insulation is applied with a thickness of no more than 2.5 - 3 mm, which allows for one-time application, depending on the volume of cylinders, economically treat the surface area from 15 to 95 sq.m. The weight of the equipment is quite large, but it is designed to transfer one employee, however, a car requires a bid to the object. To put the installation in the working condition, you do not need special skills, it is enough to explore the instructions. Pauses are allowed in the use of guns for spraying, and if the nozzles are scored, it is not necessary to be asked, since a set of 5 - 10 replaceable "nose" is provided.

Consider a complete set of a disposable installation for spraying PPU using the example of Touch'n Seal Foam Kit 1000 LD:

• dimensions of the box: 32x32x49 cm;
• installation weighs 55 kg;
• 2-component kit (cylinders A and B of 27.5 kg each);
• compact form allows transportation in the trunk of a passenger car;
• foam hardens in a minute, expanding at about 30 times;
• the base of the equipment is cylinders with components, a gun for mixing and spraying foam and 10 nozzles;
• 3-meter hose is enough to feed on any surface;
• there are instructions, a key for assembling parts, silicone lubricant and working gloves;
• the volume of cylinders is designed for 93 sq.m. at 2.3 cm of foam surface;
• the total volume of foam is 2.35 cubic meters of up to 20 kg / cubic meters;
• if you need cutting part of the foam, it is available after 3 - 5 minutes;
• the surface fully solidifies after about 1 hour;
• after the first start, it can work not more than 1 month;
• components for foam have an expiration date up to 1 year;
• cost of equipment - from 34500 rubles.

Where and how to purchase equipment for spraying PPU

Disposable installation for household use can be ordered on the websites of official representatives involved in the supply of this equipment. For this it will be necessary:

• contact the manager by the specified phone and place an application;
• pay the installation with the delivery of cash transfer by the card, urgent bank transfer or cash on delivery, depending on the terms of the supplier;
• specify whether the delivery is included in the price or adds place separately;
• after confirming the payment, the equipment will be shipped from the warehouse and delivered at the specified address;
• delivery time - as with ordinary mail, depends on distance and transport links;
• all questions on the operation of the plant for applying polyurethane foam can be clarified after receiving the phone on the same.

Features of the equipment

To start treating the surfaces of polyurethane foam, it is necessary to clean them from dust and other shallow suspension. It is not necessary to wash and process reactivities, it is enough just to carefully acquaint the plane or speach.

The equipment startup instructions contains 10-12 points, but you first need to read the entire list to the end to have a general idea of \u200b\u200bconnecting the installation and the process of applying foam.

Important:

• watch out of what is obtained as a result of the processing of planes from the installation pulverizer, and behind the work of the wizard;
• adjust the valuable experience as to which movements are ensured by uniform applying foam;
• the most important thing in the learning process is to observe how the angles, bends, irregularities, gaps and joints are processed.

Tip: If there is no prior experience, it will have to work in practice - no one will teach spray a mixture with a uniform thin layer. However, if you work hard with a solid hand, then the quality will be better than with an uncontrollable process, watching what happens in the end. It is quite difficult to correct the emboss, so it is better to start practicing on a remote vertical plane, and then foaming inclined, horizontal and uneven surfaces.

Insulation spraying PPU on the example of the balcony

The balcony is the premises adjacent to the residential room, so good thermal insulation is very important. Thermal insulation of polyurethane foam is one of the most effective methods of insulation. The mixture supplied from the sprayer will qualitatively fills invisible slots and cavities through which dampness and cold air penetrates the balcony or loggia.

The process of insulation of adjoining premises is very simple. According to the installation instructions:

• from the box we get the equipment;
• connect the hoses;
• we take the components;
• fix the nozzle on the sprayer;
• the choice of the type of nozzle is determined by a specific task (narrow or wide jet of foam when submitted under pressure);
• floor foam first on the slit, then onto other processed planes;
• excess volume of foam in some areas can be cut off after its initial hardening.

Balcony after treatment with thermal insulation, one day can be brought to the final appearance using any facing material.

Attention: the warmer on the balcony, the higher the temperature of the components supplied to the sprayer, the more effective foaming. With the "heat" foaming, the consumption of components will be less, and the applied layer looks much better, lifeline. Therefore, it is recommended to operate at a temperature of more than 15 ° C.
