The harsh operating conditions of various surfaces of houses and structures make their owners turn to special types of paint coatings. So, in conditions of increased mechanical stress, it is recommended to purchase products with improved stiffness and hardness. These include anti-vandal paints that are specifically designed for the risks of possible physical damage or graffiti. Low adhesion makes it easy to clean surfaces from dirt and other unwanted coatings.
Performance coating
The main purpose of such paints is to provide external protection, which is what physicochemical properties are calculated for. The coating creates a reliable wear-resistant barrier to shock, impact of sharp objects and dirt. Also, the paint structure is frost and moisture resistant, which allows it to be used outdoors in cold regions. Separately, it is worth noting the hygroscopic, insulating and biochemical positive qualities. The composition is well diluted with water, in the future provides vapor permeability and heat conservation. To this, it is worth adding environmental harmlessness, which is rare for coatings with a set of special operational properties. The lack of coverage can be called not the most attractive decorative qualities, but lately manufacturers have been trying to diversify model lines with compositions in different colors. For example, beautiful walls can be obtained from shades of ultra-blue, copper, emerald or light green. In the process of preparing the solution, as a rule, tinting is not allowed, so the color should be thought out in advance.
Vandal proof paint classifications
Along with paint, the existence of plasters and varnishes with enamels, which also provide the effect of protection against the effects of vandals, can be noted. In this same segment, funds can be classified according to the following criteria:
- Types of target coatings - wood, metal, foam concrete, concrete, drywall, brick.
- Object of application - industrial buildings, commercial premises, private homes, etc.
- Special operational properties - frost resistance, adhesion, wear resistance, durability, decorative qualities, resistance to water, etc.
The delivery format deserves special attention. So, in addition to the usual anti-vandal paint for walls, there are powder products. They differ in their purpose - especially for metal surfaces. The emphasis in technical and physical properties is on impact resistance and ability to withstand abrasive effects. Some modifications differ in chemical protection against alkalis, acids and, in principle, reagents.
Paint composition
Alkyd resins are usually used as the main component (filler and binder) . Moreover, in some modifications, a special hammer effect is provided, which gives the coating a special aesthetic appearance. These qualities, in particular, have Turkish quick-drying paint Mixon Hammerton for industrial use. It also uses acrylic styrene as a binder, but there are auxiliary components like modifiers and plasticizers that reduce adhesion to foreign bodies and increase the strength of the base.
Surface preparation for application
The work area is cleaned of dust, dirt and old coatings. It is advisable to check the base for resistance - flimsy elements are removed, after which an additional primer with a leveling effect may be required. It is important to consider that anti-vandal paint will give a positive result during operation only if it is applied to a smooth and reliable surface with a solid structure. For verification, you can initially use a grinding machine with a small abrasive. She will test the strengths of weaknesses and clean the base of dirt. This is especially true for surfaces with a coating of efflorescence, rust and scale.
Vandal proof coating
It is recommended to carry out work activities at a temperature not lower than 2 ° and not higher than 40 ° . The humidity level should not be more than 85%. Moreover, due to the presence of caustic substances, it is advisable to work in conditions of included forced ventilation, if we are talking about laying indoors. Paint is prepared at the rate of 1 liter per 5-6 square meters. provided that it is planned to apply one coat. Vandal-proof coating is only sprayed. This tool will allow you to better form a uniform and dense layer over the entire area. The optimal operating mode with the use of a compressor is a pressure of about 2 atmospheres with a distance between the nozzle and the surface of up to 25-30 cm. Processing on the second layer is required in porous, well-absorbing and rough areas. But each subsequent layer is stacked at intervals of 15-20 minutes. Diluting the paint to obtain a larger volume or to reduce the concentration of active ingredients is not recommended.
Cleaning the painted surface
If during operation the surface was exposed to pollution, deterioration or coating with other paints and varnishes like graffiti compositions, then the previous appearance of the walls can be restored as follows:
- Surface cleaning is carried out with a damp sponge, cloth or rags. This should be done carefully without abrasion, so that the base is preserved.
- Synthetic solvents like the 646 series will help restore the look of beautiful walls. Alternatively, you can offer a high pressure washer with the same compressor connected, but in this case the likelihood of damage to the base anti-vandal layer will increase.
- Gently with napkins and a soft rag with soapy water, excess unnecessary coatings and dirt are removed from the surface.
Reviews of anti-vandal paints
The practice of using this kind of surface protection from contamination and spoilage is mostly positive. Users point to the high resistance of the applied paint to external threats and emphasize the advantages of low adhesion, which allows you to easily remove unwanted coatings. Among the most high-quality and effective anti-vandal wall coverings, along with Mixon products, many note the Clean Walls line and Anti-Graffiti compositions. The only negative of all the funds in this segment is the high prices, which are 20-25% higher than ordinary polyurethane and acrylic mixtures.
Conclusion
The need for additional wall protection can arise for various reasons. Although manufacturers of paints and varnishes try to combine decorative qualities with enhanced protective properties, this is not always the case — at least in the form that many consumers want. Therefore, specialized anti-vandal coatings for walls and other surfaces exposed to intentional damage or accidental damage come to the fore. In terms of protective properties, these are universal compounds that provide a reliable insulating barrier against a wide range of threats. The greatest result is achieved provided that the characteristics of the anti-vandal composition and the basic primer putty are combined.
