- Does your wall have a sheen or glossy finish?
- Does your wall feel silky smooth to the fingertips?
- Can you easily wipe away dirt from your wall with a damp cloth without damaging the paintwork or leaving marks?
- Is your wall scuff resistant and hard to leave marks on?
- Have decals or stickers fallen down from your wall in the past?
If you have answered yes to 3 or more of these questions, there's a high probability that your wall has been painted with a product that has some degree of repelling/wash and wear characteristics i.e. Teflon, Latex, Silicon or similar. We would advise to err on the side of caution and at minimum, lightly sand back your wall to gently add some texture to your wall surface and remove the top reflective coat of your wall's surface. For best results, after sanding back your wall, add a water based primer.
