Walls are difficult surfaces to adhere to. Painted walls, or ones with wall coverings can require a product with a 'high grab' adhesive, as they often have an embossed or textured surface finish and standard vinyl will not stick. Walls within retail or exhibition environments can be subject to heat from lighting which can weaken the bond.

Another consideration is when applying to emulsion painted walls. Emulsion paint is a low energy surface, though if the tack is sufficient to adhere to the surface it can take the paint off on removal. Metamark does not currently offer a product with a 'high grab' adhesive (high coat weight).
