Remove any old backing paper from wall surface. Ensure hanging surface is smooth, clean, dry in depth. The wall should be painted a uniform colour to avoid patches showing through the mural.
Surface should be free from contaminants such as dirt, dust, grease, mildew, ink stains; any of these can prevent adhesion taking place. Although it isn’t necessary, you may wish to use lining paper underneath your mural.
Emulsion paint: No further preparation needed.
Porous surface (plaster, cement render): Ensure old plaster is stable and free of mould. Ensure new plaster is dry in depth. Prime surface with a PVA based primer or emulsion paint and allow to dry before hanging.
Non-porous surface (glass, gloss paint): No further preparation needed.
