Identify the surface and marking before treatment
The correct approach depends on the substrate, coating, age and condition of the surface as well as the type, coverage and age of the marking. CIC records those details before proposing a method.
- Painted and coated walls
- Concrete, brick and suitable masonry
- Metal, glass and compatible facade materials
- Signage, seals, joints and nearby finishes
- Existing damage or previous treatment
