Inspect, Repair and Prepare the Application Surface

Common Interior Wall Problems

The following conditions can affect product adhesion and performance. Be sure you address each one before installing product:

  • Too much texture surface. The more textured a wall is, the more difficult it will be for standard vinyl to adhere to it.
  • Poor bond between the paint, finish or wall covering and the substrate. If the surface finish or wall covering’s bond to the application surface is not excellent over the entire application, the product may not adhere properly and may have a poor finished appearance. Where possible, repair a poorly bonded surface finish as you would a damaged surface. For poorly bonded wall coverings, the optimal solution is to remove it, clean repair the substrate, apply primer and paint or another finish, and allow to cure.
  • Surface finish that is “out-gassing”. As a surface finish dries, it releases certain gases until it is fully dried and cured. Applying product before the process has finished can result in lifting, bubbles, and premature failure. Patched areas that are not smooth and/or have not been sealed will present a challenge.
  • Moisture behind or on the application substrate, often due to dripping or condensation, which may not be obvious at product installation degrades the vinyl's ability to adhere. This may include but is not limited to: substrates near or under cooling systems, water pipes, covered windows and uncovered windows. 
  • Any type of contamination (including dust, dirt, oil, food, vehicle exhaust, etc.) that has not been properly cleaned before product installation will also affect adhesion.
Repairing Damaged Surface Repair any damage such as holes, loose wallboard joints, and chipped or peeling paint.
  • Smooth by sanding and/or using an appropriate filler. Assure that any filler is fully cured before proceeding.
  • Seal the surface with primer and a finish, such as paint or other sealant. Two coats may be needed. Follow the manufacturer’s recommendations for surface preparation and chemical application.
  • When painting a surface, use a high quality, semi-gloss paint, not a matte paint or paint with silicone, graffiti-resistant or texturizing additives.
  • Allow the surface to cure thoroughly before product Installation.
Clean the Application Surface Dust and other contaminants on the application surface can prevent the product from adhering properly. Clean the application surface immediately before applying the product, giving special attention to edges, corners and trim.
  • For most surfaces, wash with a solution of detergent and lukewarm water. Rinse thoroughly and dry. Avoid soaps or preparations that contain waxes, oils or lotions.
  • For stubborn grease or exhaust contamination, tri-sodium phosphate cleaner may be needed. Use according to the manufacturer’s recommendations.
  • Smooth poured concrete walls may require power washing or hand washing with a stiff brush and a detergent cleaner followed by a clean water rinse to remove grease and/or exhaust contaminants. Allow the surface to dry thoroughly (at least 24 hours) before product application.
  • Even if a surface is freshly painted or finished, dust it immediately before product application using a soft, clean, lint-free cloth.
