Every roof needs some type of roofing material to serve as the building's front line of defense against the weather. Therefore, the construction industry constantly offers novelties on the coating market, and one of them is liquid roofing. Its operational properties and features will be discussed further.
Bitumen, like many years ago, is the basis for many roofing materials, especially for flat roofs, due to its specific chemical and physical properties.
Based on it, novelties are constantly being developed, and one of them is liquid rubber. This is a bitumen-polymer mastic for the roofcontaining one or more components.
Strictly speaking, "single-component" compositions can only be called as such conditionally, since they are ready-made mixtures of various substances, ready for use and not requiring mixing and other additional operations.
At the moment, liquid rubber for roofing is one of the most technologically advanced materials in the device and unpretentious in operation.
It is used both independently and as a waterproofing for other types of coatings - and, unlike classical films and membranes, it is applied over the base.
Hardly ever roofing materialson which it would be impossible to apply liquid roofing due to its high degree of adhesion (penetration and adhesion).
Among them:
- Monolithic and precast concrete
- Cement strainer
- Tree
- Metal
- Tiling (including as a bottom waterproofing layer)
- Slate
- Old coatings from roll materials
At the same time, a special advantage of the material is that on the roof, where the liquid roof is applied, the roof, as such, can be of any shape, and with the most complex geometry.
The advantages of this mastic include:
- Creation of a solid roofing carpet without seams
- No connection problems at the locations of various over-roof structures
- High elasticity
- Durability (20 years or more)
- Ease of application and fast curing
- High water resistance even under extreme conditions
- Chemical and biological resistance
- Wide operating temperature range (-60 - +110 °С)
- Ecological safety (can be used even indoors)
- Low material consumption (1-3 kg/m2)
The material is also applied in almost any way:
- brush
- Roller
- Spatula
- rubber squeegee
- spraying plant
At the same time, high fire safety is ensured, since this roof is arranged in a cold way, without the use of open fire. .
Hardening occurs almost immediately after application. You can walk on the coating, and full readiness comes in a day.
Minimum preparation is required, similar to a conventional screed or surface painting: cleaning from dirt, degreasing, if necessary - a primer
Important information! Degreasing and priming work must not be carried out using substances based on petroleum products.
A particularly effective area of application of the material is the repair of the roof with liquid rubber. As a rule, it is performed on the old coating of rolled materials.
It is noteworthy that in this case, both when completely covering the old roofing carpet, and when applying repair patches, the removal of the old coating is required only in places of chipping. Even bubbles, after cutting them, can be filled with mastic.
Advice! In order to save money, when installing a roof covering, you can use rolled material as the main material, and process complex areas with bitumen-polymer mastic - junctions, vertical and inclined surfaces, etc.
Of course, no material is without flaws, and liquid roofing also has them.
These include:
- Relatively high price
- Sensitivity to solvents and other petroleum products
- Possibility of removing the coating, if necessary, only mechanically
However, the advantages still outweigh: the speed of the device, the possibility of applying to vertical surfaces (without subsequent slipping under the influence of heating by sunlight) - this material has no equal. Separately, it should be said about the high elasticity.
Thanks to it, when the ambient temperature changes, even the most abrupt one, the roof will work together with the base, which will not allow damage to occur either in the coating itself or in the places where the carpet adjoins various elements of the roof.
When installing additional protective layers (substrates from below and a hard coating - screeds, cement tiles, etc.) on a material such as, for example, Reinforced liquid roofing can also be exploited.
Although mastic is usually produced in black, there are also color options. It can also be tinted with organosilicon or water-based dyes.
The remarkable properties of liquid rubber (although it's not actually rubber, it doesn't have the obligatory rubber in it) make it a versatile and very practical coating.
And if you additionally cover it with protective paint from ultraviolet radiation, such a roof will last much longer than the 20 years stated in its characteristics.
