Start with a smooth, clean, and dry surface prior to installing.
The ideal surface will have at least two coats of flat latex paint and
any remnants of a previous wallcovering removed. A primer sealer
should be used on unpainted drywall or glossy painted walls, use:
Professional Ultra Prime (PRO-977)
Golden Harvest White Bite
Allpro Ultra Prep 685
Fill in any cracks or holes, sand and paint
if necessary. For textured walls, cinderblock, paneling, or cement apply a liner paper
then paint with two coatings of water based latex paint. The mural will
not hide flaws in the wall.
