People who have ever taken part in removing graffiti from surface understand that the removal process is harder than applying. Normally the removal method used should depend on the type of surface in question. Various methods have been developed in different parts of the world for this job. However, when in need of the best graffiti removal Aurora is the right place to pay a visit.
Some of the major removal methods include use of chemicals, sandblasting, repainting, scrubbing, and emulsifying among others. This article discusses surfaces and the best methods applicable on them. Surfaces on which graffiti is commonly applied are metal, masonry, plastic, glass, and wood. A combination of different methods may be required to achieve maximum removal on all of the surfaces named above.
Common paint thinners can perform fine on metallic surfaces. Some of the thinners that can be used are acetone, lacquer thinner and mineral spirits. There is no problem with trying other chemical products. Bronze or steel wool can be used to rub off any remnants of paint. Rubbing with light sandpaper is not too bad also. Power washing may be useful in removing paint remnants due to deeply seated graffiti marks.
The condition of wooden surfaces dictates the method that can be used on them. Mineral spirit may do well on un-weathered wood still in good condition. However, mineral spirits are absorbed by weathered wood making the spirits ineffective. The absorbed spirit drives paint particles deeper into the wood instead of removing them. Power washing also drives paint deeper leaving repainting the only best option to be utilized.
Plastic surfaces should be wiped using light penetrating oils. Paint thinners should never be used because they may cause permanent tackiness or clouding on the plastic surface. A better method for use on plastic surfaces is sandblasting. This method is however only applicable on hard and strong plastics. A soft rub using ultra-fine bronze or steel wool may also work well on some forms of plastics.
Masonry surfaces are the most challenging. Such surfaces should be pressure washed at pressures of 3000 psi. Using the right model of a pressure washer, such pressures should remove the graffiti. Sandblasting is the other option to think of if power washing fails. When using sandblasting, one should be careful not to direct the stream of abrasive at a specific point for too long. This etches the surface instead of cleaning it. Painting should be considered as the last option.
Fragility of glass makes it another tricky surface to clean. Glass surfaces also get etched easily with least efforts. Glass surfaces should be scrapped with razor blades to avoid etching or breaking them. The blade should make an angle of 30 degrees with the surface and must be used in a holder. The efficiency level of this method on glass is 99 percent. Water and ultra-fine bronze wool may be used to remove any remnants left behind after scrapping.
Workers face certain dangers from using some of the techniques named above. As such, one must exercise caution to avoid injuries. Wearing respirators and sunglasses is one of the many ways of avoiding harm.
