RECOMMENDED SOLUTIONS
- Prep the surface properly by making sure it is clean, dry and free of grease, dust or mildew.
- Use a quality primer like Valspar® Stain-Blocking Bonding Primer/Sealer when painting over stained, porous or previously unsealed areas.
- Apply one to two even coats of paint with the correct roller nap for the wall texture.
- Allow the paint to fully cure (typically 7 days) before washing or exposing to heavy use.
