The type of brick wall you have will determine the best method to get rid of graffiti. Smooth surfaces, such as plastered walls, are easier to clean than brickwork that has more texture. It may be possible to repaint the graffiti to get rid of it completely. Sometimes the graffiti is so severe that it can only be removed by a professional cleaning product. Some people use vinegar or lemon juice to remove graffiti that is just a little bit stubborn.
This may sound like a good solution but it will not work for all types of graffiti cleaning. A professional can use a chemically reactive acid cleaner to remove graffiti. However, it is not possible to know how much acid to use without putting your health at risk. You can use baking soda or organic alternatives to safely remove graffiti from brickwork if you are concerned about your health. Use a sponge or stiff brush to scrub the area. You should not let any paint residue or paint get off your wallpaper or paint. You can then apply another coat of paint to ensure that the paint is fully dried.
Spraying or blast cleaning may be required to remove graffiti from brickwork that is severely damaged or scratched. High pressure air is used to blast dirt and abrasive particles into graffiti areas. A rotary scrubber machine is recommended for best results. Although this is more costly than other methods of graffiti cleaning, it is ideal for areas that are severely damaged. When using an oscillating or rotary scrubbing machine, you should not use too much pressure.
You might use a power brush or vacuum to clean brickwork. These tools can be used on bricks and mortar but not concrete or tiles. These tools are not suitable for all types of graffiti removal. They also cannot be used to remove graffiti from metal or painted surfaces. A power brush or vacuum is fine for light graffiti removal, but they are not recommended for thick layers of paint.
After trying a number of different methods to remove the paint, brickwork may still be covered in paint. You can try combining chemical cleaning products with your first choice of abrasive methods. A combination of muriatic acid, citrus fruits, and acetone can be used to gently rub off any remaining paint. This is a great way for your walls to be restored. It is also useful in removing mildew and mold.
You could also hire a professional to clean your brickwork. This service is offered by many reliable companies. They can often remove graffiti from damaged walls within a day. These experts will use special products that are designed to remove graffiti from brickwork and restore it to its original condition. These chemicals are not recommended for children under the age of 6. This is an alternative to major home renovations and repairs.
Another way to remove graffiti from is using compressed air. Although it can remove large areas of paint quickly, this method can be a bit rough around the edges. It is best to not use blast media products unless you feel confident using them and have tried it several times before. Too much blast media cleaning fluid can cause damage to the walls. This can cause bricks to fall out of place or chip away.
For some, a good mix of muriatic acid, lemon juice, and club soda can be used. Mix crushed glass and club soda together to make a paste. You can apply this paste to bricks damaged by acid spill-overs. This will give you a more uniform finish. This paste is sticky and can cause bricks to chip if it is used repeatedly.
