Making the waterproofing of the roof of the liquid rubber - esteem, characteristics and method of applying

Liquid Rubber - a relatively new material in the construction market, but the prospects for its use became immediately apparent.Of course, easy and seamless coating, resistant to high temperature, frost, rainfall, which can be applied to various shapes of the roof and with lots of protruding parts, just to gain popularity.

liquid rubber can completely replace traditional bitumen, mastic based on it, roofing and other flexible roofing materials, which we discussed here.It can be used as a substrate for other waterproofing roofing materials, if the image of the house provides for their use.As an intermediate layer liquid rubber has an excellent sound and acts as a heat insulator and generally strengthens the roof.

Advantages of liquid rubber

On liquid rubber composition consists of two components: an aqueous base, and the emulsion of modified bitumen with elastomers, polymers and catalyst (calcium chloride solution).Physical and chemical properties of the material determined by the unique properties of liquid rubber as roofing.

• Excellent adhesion to most building materials: concrete, brick, stone, slate, metal, glass, plastic.
• The complete absence of seams and absolute waterproofing, even on the roofs of complex shape, with trumpets, peaks, ridges.
• existing small cracks and irregularities are tightened rubber itself.
• Highly elastic and durable coating due to high content of polymers.The works can be carried out without removing the previous material.
• coating of liquid rubber weighs several times less than that of other materials, therefore does not require the strengthening of bearing structures of the roof and can be used on buildings with a lightweight foundation.Chemically resistant
• - not corrode and does not react with most substances, will not burn and does not emit toxic compounds, since it does not contain volatiles.
• tolerate high and low temperatures, as well as sudden changes without cracking and blisters, in contrast to the same bitumen.Not destroyed by ultraviolet light.
• Roofing work using this material do not require electricity, water, fire, are carried out safely and quickly, without the involvement of a large number of people.
• long operating coverage period, the assurances of producers, up to 20 years.

Disadvantages

By conventional disadvantage is the need for a special apparatus for applying liquid rubber on the roof, for example, Training and Housing Complex-2.But the price is quite buy it allows the professionals who are engaged in construction or roofing device.Faster roof covering liquid rubber compared with other materials will allow for a short time to recoup the costs.Those who builds a house on their own, may take the unit out, how to plant, firms engaged in the supply of the liquid rubber, provide this service.

Application

applied to the roof of the liquid rubber-coated using a two-channel mixing device, which is under the pressure of the spray a few meters ahead.Both components are mixed in a "flare" and sprayed through a "bait."This method makes it possible to obtain a thin (2-4 mm) and uniform layer without a "bald spots" and adherent coating without blistering and peeling.

The roof is covered with liquid rubber in dry weather, with temperatures above 5 ° C.Pre surface must be cleaned of debris and dust.If it contains grease, it is necessary to get rid of them by using a gas burner, as these sections of the material join worse.

Sprayed material strips 1-1.5 m, uniformly and without gaps.About parapets, pipes and other protrusions covering must be reinforced with a mesh or cloth construction.

liquid rubber hardens almost immediately, forming a smooth seamless membrane is fully cured coating on average per day, depending on the temperature and humidity of the environment.After solidification of a roof can be painted with special paint marks.

liquid rubber can be used not only as a roofing material, but also as a corrosion protection for metal structures, waterproofing basements, foundations, slab joints, swimming pools and ponds.
