When there is a need for facade decoration of the house, the owners of their own homes think about what material to choose for this. If you plan to carry out the work yourself, then it will be easiest to paint the outer wall. Among other options, the market offers perchlorovinyl paint, which will be discussed below.
Key Features Reviews
The above paint is used for exterior decoration of buildings for various purposes. Among the ingredients should be highlighted:
- perchlorovinyl resin;
- pigments
- fillers.
The latter are dissolved in xylene or solvent. According to users, this mixture is quite expensive, but forms a strong layer on the outer wall. Home craftsmen argue that the surface must be carefully prepared before applying the paint. You need to get rid of the old layers, and use a sandblasting machine more efficiently and conveniently . If it was not possible to get it, then cleaning can be performed with steel scrapers. It is better to refuse manual cleaning, because this approach rarely allows to achieve high quality work.
Perchlorovinyl paint is produced in the factory, at the time of delivery it has the desired color. Consumers do not recommend diluting it with solvents, as well as mixing with other paints. Work in most cases is carried out using suspended cradles or scaffolding. The paint contains a flammable solvent - xylene or solvent. For this reason, home craftsmen are advised to adhere to safety measures at the place of work.
It is important to organize fire control. If the concentration exceeds 0.2 square meters per 1 liter, then xylene and solvent can have a harmful effect on human health, so when painting, use a respirator and glasses.
Classification
Perchlorvinyl paint, like any finishing materials, is divided into several varieties, which differ in application method, purpose and amount of volatile substances. Technical characteristics of these varieties are different.
Among others, one can distinguish enamel marked XB-125. This compound is used for painting metal and wood surfaces. On sale you can also find perchlorovinyl paint -161. This is a mixture of different pigments and fillers, which are dissolved in PVC varnish. The concentration of the latter is 10%. The share of non-volatile substances reaches 47%. This type of enamel is used for painting plastered and brick buildings.
Modified enamel is a material marked XB-182. In it, the share of non-volatile substances is at the level of 36%. Paint is used for decorative painting of brick and concrete surfaces. If we compare the last two enamels, then the most widespread is the front perchlorovinyl paint XB-161, which is due to the low cost of the material. Among other things, this enamel is almost universal in terms of temperature, because it can be applied in the range from -20 to +40 ° C.
Technical characteristics of XB-161
If you decide to purchase a variety of enamel XB-161, then you should familiarize yourself with its technical characteristics. Among one of the important features, it is necessary to highlight the time of complete drying. It does not exceed a day when the ambient temperature is 20 ° C and above. The paint consumption per unit area is approximately 270 g. This is true when the layer thickness is 25 microns.
The paint front perchlorovinyl brand XB-161 has a viscosity ranging from 30 to 45 s. This value allows you to use a spray gun, and the addition of solvents or thinners is not required. The amount of non-volatile substances reaches 47% and no more. After drying, the layer gains bending elasticity of 5 mm. The other two varieties of enamel have similar indicators, but still differ.
Additional information about paint grades A and B
XB-161 paint is offered for sale with the marking A. Its application is carried out on a previously prepared surface. However, the old coating can also be used as a base. But marking B is used for restoration work. The characteristics of the XB-161 does not change depending on the brands. You can see the brand in the certificate.
The surface is tested before application. In order for the layer to retain its properties for a longer time, the base must be evenly plastered, dry and clean, and also free of cracks. If the surface was coated with acrylic silicate or silicon-organic materials, the layer is protected. Otherwise, the composition is not applied.
The paint for perchlorovinyl facade grade A is not covered by the warranty if the above conditions are not met. Before application, the composition is mixed. Work can be carried out using a pneumatic spray gun, brush or roller. In the first case, the mixture is diluted with xylene, solvent, or a mixture thereof to form a working viscosity. But if you plan to use one of the two remaining tools, then you need to use paint with final viscosity.
Reviews of paint HV-161 B
According to consumers, the material described in the article has its positive and negative qualities. Among the advantages it is necessary to highlight:
- high degree of adhesion;
- the presence of several varieties;
- the ability to carry out work even at low temperatures;
- preservation of deep and saturated colors for at least 5 years of operation.
The paint facade perchlorovinyl brand XB-161 B is absorbed into the base structure, which allows the formation of a moisture barrier. The paint itself for a long time maintains its integrity. To further increase adhesion, home craftsmen advise using perchlorovinyl primer in the preparation process.
Additional opinions
Consumers also like the availability of several types of enamel on sale. This allows you to choose the composition for a certain type of surface. Perchlorovinyl paint is also good because it can be applied at low temperatures. And after drying, the layer retains a deep color during the first five-year period. Such paints begin to fade only after 3 years of operation, but even after a five-year period they remain bright enough, which is especially true when compared with acrylic enamels.
Negative reviews
The described paint, despite all its advantages, has some disadvantages. Among them, the impossibility of working in heavy rain and heat should be highlighted. However, consumers emphasize that none of the modern colors can boast of this.
Home masters advise you to pay attention to the low elasticity of the composition, so the rough surface should be fairly smooth. Otherwise, you may encounter a problem of cracking on the base.
Conclusion
In order to achieve a positive result when painting the facade with the described paint, it is necessary to constantly mix the mixture during the work. If necessary, the composition is diluted. Xylene or solvent is used as mixtures for this. However, their volume should not exceed a tenth of the total mass. The application of paint is carried out in two layers. The first layer should almost completely absorb into the base material. Wait between layers for at least 24 hours.
