Why billboard and signage graffiti is a priority in Shoreditch and East London

When graffiti sits on a billboard or a signage panel it can obscure important information hinder readability and convey the wrong message about your brand. Timely professional removal is essential to preserve professional appearance and to deter future tagging.”

Common signage materials found in London billboards and signage

Outdoor signage uses a range of materials that respond differently to graffiti and to cleaning methods. Being aware of the material is essential to choose the right removal method without causing damage. Below are the main signage materials you are likely to encounter in Shoreditch and across London.

Vinyl wraps and decals

Vinyl wraps are common for advertising panels and vehicle graphics. They are usually polyurethane or PVC backed. Graffiti on vinyl wraps often involves paint markers spray paint or posters applied directly onto the surface. Removal requires careful solvent selection to avoid dissolving the base material or causing blistering. For vinyl the best method is usually a solvent safe graffiti remover followed by thorough rinsing. In some cases heat or gentle mechanical action helps lift the paint without damaging the vinyl layer.

Posters and adhesive posters on boards

Posters placed on boards or metal panels are a frequent target. The glue residue can be stubborn and may require a dedicated poster remover or solvent to soften the adhesive before lifting. Peel back slowly and use a plastic scraper to avoid scratching the surface. It is important to Neutralise any adhesive residue to prevent staining or future adhesion of new graffiti.

Dibond and metal signs

Dibond is a popular aluminium composite material used for sign panels. It offers a rigid and durable surface perfect for long term outdoor use. Graffiti on Dibond is typically spray paint or marker. The removal approach for Dibond often involves a paint remover suitable for metal surfaces followed by a gentle wash. We take care to avoid warping or dulling the finish during cleaning. On raw metal surfaces it is common to seal the area after cleaning to prevent corrosion.

Acrylic and polycarbonate signs

Acrylic and polycarbonate signs give excellent transparency and impact resistance. Graffiti on these plastics can be tough because solvents may craze or fog the material. We use speciality cleaners that are safe for acrylic and polycarbonate. In some cases if the graffiti has etched the surface or left stains we may recommend resurfacing or replacing the panel to restore clarity and legibility.

Foam board Coroplast and PVC signs

Foam board and coroplast are lightweight sign materials used for temporary or semi permanent installations. They are porous and can absorb solvents which makes it tricky. We tailor our method to the substrate to avoid saturation and to prevent warping. Our team uses gentle cleansing techniques and when necessary we replace damaged panels with matching boards to achieve a consistent appearance.

Glass and glazed signage

Glass and glazed plastics require specific cleaning because etching or staining can occur if the wrong chemical is used. We employ products that are safe for glass and avoid scratching or distorting the surface. For etched graffiti on glass we can apply sealing techniques to reduce future staining and protect against further graffiti.

Why graffiti removal on signage requires a specialist approach

Billboards and signage surfaces are often more delicate than brick or concrete walls. The substrate can be layered with protective coatings paint or laminates. A wrong cleaner can remove the top coating or damage the underlying material. Our team is trained to identify the surface and select a cleaning method that removes the graffiti while preserving the integrity of the sign. We always test a small inconspicuous area first to ensure compatibility. This careful approach minimizes risk and ensures a clean professional result.

Step by step process for removing graffiti from billboards and signage

When you contact us for a signage graffiti removal in Shoreditch or surrounding areas we follow a precise process designed to protect your investment. The steps below outline our standard practice.

1. Initial assessment and on site inspection

We arrive equipped to inspect the sign in question. We identify the substrate material note any coatings and determine the type of graffiti present. We also check for any risk to surrounding surfaces and consider weather conditions that may affect the removal process. A quick plan is created that aligns with your signage goals and the time required for restoration.

2. Safety planning and isolation of the work area

Outdoor signage often sits in busy pedestrian and traffic zones. We set up safety barriers where needed and ensure passers by and adjacent properties are protected. We wear appropriate PPE to protect eyes skin and airways from solvents vapours and dust. We also consider drainage and environmental controls to avoid contamination of watercourses and local drains.

3. Choosing the right removal method for the material

The material determines the cleaning method. For vinyl and plastic signage a solvent based graffiti remover is typically used followed by rinsing. For painted graffiti on metal or Dibond surfaces we may use a specialised remover that targets paint while protecting the substrate. For stubborn marks we may apply heat or gentle mechanical action in a controlled manner. In all cases the method chosen minimizes risk to the surface and preserves color and sheen.

4. Scraping lifting and careful cleaning

We use plastic scrapers to lift graffiti without scratching the substrate. For glossy signs or laminates we are careful not to create micro scratches. We rinse thoroughly to remove any residue that could attract future dirt. If a sign has a protective coating a top up may be necessary to restore the protective layer after cleaning.

5. Adhering adhesive residues and post clean protection

Adhesive residues from posters require a specific solvent that dissolves glue without damaging the surface. We apply the solvent gently let it dwell and then wipe away before rinsing. After cleaning we assess the need for protective coatings such as anti graffiti coatings or a new laminate to prevent future tagging. A protective layer can make future graffiti easier to remove.

6. Final inspection and client sign off

We walk you through the results noting any remaining concerns. If the signage is damaged beyond immediate use we discuss replacement options and timelines. We also provide guidance on next steps for maintenance and prevention.

7. Aftercare recommendations

To keep signage looking its best we recommend routine inspections and potential anti graffiti coatings. These coatings create a barrier making it easier to remove future graffiti without harming the original surface. We tailor maintenance plans to the signage material and environmental exposure typical to Shoreditch traffic and weather conditions.

Common graffiti types you will see on signage and how we remove them

Signage surfaces attract different forms of graffiti including aerosol spray paint sticker posters and marker tags. Each type demands a slightly different approach.

• Spray paint on vinyl and metal signs is cleaned with solvent based removers that are safe for the substrate. We avoid aggressive methods that could melt or warp thin sign materials.
• Marker or felt tip graffiti often sits on laminated or painted surfaces. We remove with low odour cleaners designed for plastics and panels. After removal we recondition the surface to maintain the original finish.
• Poster and sticker graffiti leaves adhesive residues we remove with specialist solvents then completely wash the area to prevent staining and to restore a smooth surface.
• Acid etched graffiti on glass or mineral layers may require restoration methods that include careful polishing or surface restoration to restore clarity.
