SURFACE PREPARATION FOR WALL GRAPHICS

The preparation of a wall is the most vital part of the installation process. If the wall is not properly prepared, the graphic will fail more likely than not. The following instructions are meant to be used as a guideline and should be followed in accordance. Any deviation may render additional expenses.

NEW CONSTRUCTION

1. All drywall dust must be removed prior to painting the wall

2. The wall must be painted with primer all the way to the perimeter edges. *Note when the final application is wallpaper vs (adhesive backed) vinyl, a non-PVA primer must be used. Acrylic based Zinsser 1-2-3 is one example

3. Check the wall for any defects or imperfections. Any imperfection will be magnified once the graphic is installed

4. The wall must be painted with no less than a semi-gloss finish

5. The paint must dry/cure for a minimum of 7 days. If oil base, dry time is two times or what is noted on the can label

6. The entire area of the wall that is to have the graphics applied is to be painted

7. Vinyl graphics will not adhere well to unpainted drywall, drywall mud (spackle), primer only or paints that have a finish of flat or eggshell

8. Any paint that states low or no VOC’s has an extreme potential of failure when installing graphics.

100% non-low VOC paint is required for optimal marriage of graphics and wall surface

Recommended paints would be:

A) Pittsburgh Paints (PPG) – ultra interior/exterior or

B) Speed-Hide Pro-EV. Both can be tinted

EXISTING WALLS

1. Check the wall for any imperfections

2. Wipe the area where the graphics are to be installed

3. Make sure that there are no lights, ex: halogen bulbs, which will emit extreme amounts of heat within 24” of the proposed graphic location. This light can burn the material over time. It can also cause 4mil materials to shrink and curl away prematurely from the edges and corners.
