What to look for:
Stained Concrete Walls
If the walls are made of concrete, the permeable surface tends to absorb staining agents. As a result, no amount of scrubbing can get the dirt off. This is where a thorough clean using concrete-safe cleanser will help. It lightens the stains and usually removes them completely.
Wall Coating Systems
If your house or building has been coated with a textured wall coating system they are usually self-cleaning and look fresh for years.
However, depending on where you live, small airborne particles of dust or dirt can settle on the top of each tiny piece of texture in your wall coating. These pieces are usually crushed marble or perlite and give added strength to the coating and improve weather protection. But unfortunately can also act as a handy ledge for dirt. The end result is a dull or dirty look to the walls.
Walls with these coatings can be freshened up with a light clean using a LOW pressure washer – not a high pressure one, otherwise, large chunks of the coating could be ripped off!
If your walls have suffered from an outbreak of graffiti it can be much harder to remove than you think. Certainly harder than it was to apply!
This is especially true when it’s on rough unpainted brickwork, or concrete walls, which if left untreated for any length of time can prove impossible to completely eradicate and the best that can be done is to reduce it to an unrecognisable ‘shadow’.
24/7 Drains have the skills and the equipment to help remove unsightly graffiti. Sometimes it may take several treatments, but we aim to get rid of it in the end! Then over time, the ‘cleaned’ area should weather back to the original colour and texture.
If your walls have been ‘Tagged’ don’t delay!
