Structured procedures are required when removing graffiti from walls of buildings. This is to ensure that the structural integrity of architectural work is maintained on the buildings. It’s more likely to leave the surface of a wall more “ugly” after removing graffiti. Therefore, removal techniques need to be adopted for purposes of preventing wall surfaces from further damage. To protect further damage of the faces of buildings, guidelines for graffiti removal should be adhered. Let’s look at the main three guidelines for appropriate removal and surface protection; Be sure to visit our website for pressure washing and graffiti removal today!
1. Taking into consideration nature of surface and substance to be removed
There’re many surfaces where graffiti can be applied. Some will be applied on stones, concrete walls, pavements, wood surfaces, among others. However, application of the graffiti on these surfaces can be done through different ways and forms. For instance, using spray paint, using makers, lip stick, shoe polish, and etching products. Some graffiti can stay on a surface for several years, depending on whom, and what was targeted. However, the longer the graffiti on a surface, the harder it becomes for removal. The substance to be removed on the other hand, depends on the surface and the technique used. Most times, you’re going to have to call a pressure washing company in Vancouver to finish off the small details.
2. The removal technique
The graffiti removers are mostly sold in large quantities for use by cities and towns. However, removers sold at retail level are for simple graffiti on walls of homes and other smaller surfaces. The following are common graffiti removal techniques;
Painting over the graffiti
Paint is used to cover the graffiti surfaces, and it’s considered as the safest method compared to use of chemical solvents when removing graffiti.
Using chemical removers (chemical solvents)
Chemical solvents are of different varieties such as alcohol, mineral spirits, and turpentine, among others. These solvents dissolve the graffiti paint during removal. A stronger solvent will remove graffiti paint faster. However, caution is taken when dealing with strong chemical solvents. Wise selection is necessary since some chemicals may ineffectively remove and protect the surface.
Pressure washing of graffiti paint
This involves using a solvent combined with water, or just pure water, to remove graffiti paint. There is equipment used to remove the paint through pressure washing. Sometimes, a chemical solvent is applied then pressurized water washes the surface. Pressure washing should be done carefully since it can damage the surface being treated.
3. Applying a protective layer on the treated surface
There’re two types of protective layers; sacrificial coating and non-sacrificial coating. Sacrificial is semi-permanent since it gets off upon graffiti removal, while non-sacrificial doesn’t get off upon graffiti removal.
The process of graffiti removal is carried out mainly in towns and cities. This is the reason why there are quite less homes with graffiti removers. There are also retailers who sell removers for graffiti removal on small surfaces. However, it’s easy to hire the dealers to remove extensive graffiti from your home walls and other surfaces. This is safer since they know how to handle chemical solvents appropriately.
