The harsh operating conditions of various surfaces of houses and structures force their owners to turn to special types of paint and varnish coatings. So, in conditions of increased mechanical loads, it is recommended to purchase products with improved indicators of rigidity and hardness. These include anti-vandal paints, 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.
Covering performance
The main purpose of such paints is to provide external protection, which is what physico-chemical properties are calculated for. The coating creates a reliable wear-resistant barrier against impacts, sharp objects and dirt. Also, the structure of the paint is frost and moisture resistant, which allows it to be used outdoors in cold regions. Separatelyit is worth noting the hygroscopic, insulating and biochemical positive qualities. The composition is well diluted with water, further provides vapor permeability and heat saving. To this it is worth adding environmental friendliness, which is a rarity for paintwork with a set of special performance properties. The disadvantage of the coating is not the most attractive decorative qualities, but recently manufacturers have been striving to diversify the model lines with compositions in different colors. For example, beautiful walls can be obtained from shades of ultra blue, copper, emerald green 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-resistant paint classifications
Along with paint, one can also note the existence of plasters and varnishes with enamels, which also provide the effect of protection against vandalism. In the same segment, funds can be classified according to the following criteria:
- Types of target coatings - wood, metal, foam concrete, concrete, drywall, brick.
- Application - industrial buildings, commercial premises, private houses, etc.
- Special performance properties - frost resistance, adhesion, wear resistance, durability, decorative qualities, water resistance, etc.
Delivery format deserves special attention. So, in addition to the usual anti-vandal paint for walls, there are also powder products. They differ in their purpose -especially for metal surfaces. The emphasis in technical and physical properties is on impact resistance and the ability to withstand abrasive effects. Some modifications also 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 also provided, giving the coating a special aesthetic appearance. Such qualities, in particular, are possessed by the Turkish quick-drying paint Mixon Hammerton for industrial use. It also uses acrylic styrene as a binder, but also contains auxiliary components such as modifiers and plasticizers, which reduce adhesion to foreign bodies and increase the strength of the base.
Preparing the surface 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 bear in mind that anti-vandal paint will give a positive result during operation only if it is applied to a flat and reliable surface with a solid structure. To check, you can initially use a grinder with a fine abrasive. She will test the strength of weak points and clean the base of dirt. This is especially true for surfaces with a touch of efflorescence, rust anddross.
Application of anti-vandal coating
It is recommended to carry out work activities at a temperature not lower than 2 °С and not higher than 40 °С. The level of air humidity should be no more than 85%. Moreover, due to the presence of caustic substances, it is desirable to work under conditions of forced ventilation, when it comes to laying indoors. The paint is prepared at the rate of 1 liter per 5-6 square meters. provided that it is planned to apply one layer. Laying anti-vandal coating is carried out only by spraying. 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 on porous, highly absorbent and rough areas. But each subsequent layer is laid at intervals of 15-20 minutes. It is not recommended to dilute the paint to obtain more volume or reduce the concentration of active ingredients.
Cleaning the painted surface
If during operation the surface has been contaminated, damaged or covered with other paints and varnishes like graffiti compounds, then you can restore the previous appearance of the walls as follows:
- Surface cleaning with dampened sponge, cloth or rag is in progress. This must be done carefully without abrasive action, so that the base is preserved.
- Returnthe appearance of beautiful walls will help synthetic solvents like the 646 series. Alternatively, a pressure washer with the same compressor can be offered, but in this case, the likelihood of damage to the base anti-vandal layer will increase.
- Excess unnecessary coatings and dirt are carefully removed from the surface with napkins and a soft cloth with soapy water.
Reviews on anti-vandal paints
The practice of using this kind of surface protection against contamination and damage is mostly positive. Users point to the high resistance of the applied paint to external threats and emphasize the benefits of low adhesion, which makes it easy to remove unwanted coatings. Of 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 products in this segment is the high prices, which are 20-25% higher than conventional polyurethane and acrylic mixtures.
Conclusion
The need for additional wall protection can arise for various reasons. Although paint and varnish manufacturers try to combine decorative qualities with enhanced protective properties, this does not always work out - at least in the form that many consumers want to get. Therefore, specialized anti-vandal coatings for walls and other surfaces exposed tointentional damage or accidental damage. In terms of protective properties, these are universal compositions that provide a reliable insulating barrier against a wide range of threats. The greatest result is achieved by combining the characteristics of the anti-vandal composition and the base priming putty.
