How does Digital Wallcovering work?
How do I design a project using the HP WallArt APP?
Due to the variety of paints available and the variety of surface finishes, it is critical to test compatibility of a print media product with each specific wall. In order to achieve the best performance or to make the best recommendation, you should carry out a sight survey where different media options are tested.
- Contact Re|surface to determine what are the best products for your specific job. The recommendation will depend on the wall surface as well as product criteria. For instance, a three month promotional wall wrap will require a different product than a permanent project.
- Print a test image using the printer for the actual job. Print a 2’ x 3’ size image with the same ink saturation as the real
job. You should print samples of each possible media. (If printing an actual sample is not possible, please contact Re|surface to get generic media printed samples.)
- Allow print to outgas overnight. Apply overlaminate if needed.
- Clean and Prepare Surface: Check wall surface for dust level as surface dust could impact adhesion to the wall. It is recommended that the wall be dusted off with a lint-free dry cloth. Spray the wall area with 50/50 (IPA/Water) mixture and wipe off dust and surface contaminants.
- Install: For uneven textured surface, install film on wall with foam roller slowly with a heat gun, softening the film 1” ahead of the roller.
- Install: For smooth surface, install the film with a Teflon squeegee and post heat graphics.
- Inspect and Remove: After 24 hours of installation, observe for edge lifting or curling of graphics. Any sign of edge curl or lifting indicates the product is not compatible. For each sample that passes visual inspection, score/cut 3” of the print and peel it off the wall. If the graphics take effort to remove, then vinyl and surface are compatible. If time allows, come back 1 week later and cut off another 3 inches and check if graphic
remained on the wall.
- Product Selection: Select the product that best meets the criteria and required performance of the job. Permanent projects should have a product with the highest bond, while removable graphics should have a bond that is compatible but with a lower final bond.
Wall must be smooth, clean and completely dry before painting.
- Painting over wet or damp drywall compound will retard paint drying and cause inconsistent graphic adhesion.
- Painting over dusty drywall will impair primer bond to wall surface.
- Minimum drying time of drywall compound must be 24 hours. If several passes of drywall compound have been applied the drying time may be extended.
Not all latex paints will be compatible with pressure sensitive adhesive (especially Zero/Low VOC paints) and vinyl film should be tested in an inconspicuous area to assure that an adequate bond develops over 24 hours. See Tip 39 for details. No installation should take place until media and paint are deemed compatible. Freshly painted walls must dry for the time specified by each paint manufacturer and/or for a minimum of 1 week. Primer should be allowed to dry for a minimum of 3 days.
Test vinyl wall/paint compatibility prior to any wall project.
Wall wraps are an excellent means of expanding advertising space and extending your brand message. To protect your graphics and create the best first impression, the following installation recommendations are provided.
- The surface must be entirely dust free. Pressure washing with 1:20 ratio of TSP (trisodium phosphate) to warm water mixture followed by a warm water rinse will remove most surface oxidation and accumulated debris and chalk. For heavier accumulation, use a stiff bristle brush with the same TSP solution. Warm water rinse and allow the wall to dry for two (2) days.
- For the best long-term results, seal the surface with a coat of paint or concrete sealer, allowing a minimum of two weeks drying time. In cold or high humidity environments, an extended drying time is recommended. Failure to allow paint to fully cure will result in an incomplete bond of paint to wall surface. Subsequent repositioning of graphics may lift paint from the wall. Use of a sealant provides a more reliable base for installation. Additionally, removal will be much easier: the adhesive will strip off more cleanly as will incidental adhesive residue.
Installation Tools Required:
- Heat Gun
- High Density Foam Rubber Roller Designed for Wall Installation
- IR Thermocouple
- Heat Resist Gloves
To assure highest adhesion the following steps are recommended:
- Align graphic at the top and hinge apply masking tape to secure the top edge of graphics.
- Remove liner from graphics and loosely tack on graphic to wall.
- Preheat film to a minimum of 100ºC prior to rolling on the wall using 2-3” high density rubber roller horizontally across the wall side to side.
