• Extra precaution should be used when applying wall graphics to "Low VOC" or "Zero VOC" paints as these paints may exhibit lower adhesion levels.

• Allowing graphics extended time after application before removing application tape allows adhesive further time to create a full bond (up to 24 hours).

• Water-Based Adhesive vs Solvent-Based Adhesive

• Water-Based Adhesive: 

Products with a water-based adhesive, such as ORACAL 631, typically are a low-cost solution for either indoor or short-term outdoor graphic applications. This type of adhesive is found in a wide range of versatile projects like decorative wall graphics, indoor wall murals, and way-finding signage. Avoid wet applications when applying water-based adhesive products as this will interfere with the bonding process to the substrate.

• Solvent-Based Adhesive:

Solvent-based adhesive products, like ORACAL 651 are designed for more demanding and longer-term applications. The components of this adhesive are combined using solvents, thus allowing a structurally stronger adhesive that is more resistant to chemicals, cleaning agents, and wider temperature ranges. Another important attribute is the ability to wet apply graphics without the worry of the adhesive losing bond to the substrate.
