Do You Need Sealer?
Preformed Thermoplastic, while a great product, is still susceptible to contaminants and moisture that can prevent the preformed marking from sticking properly to the pavement. There are times when a sealer is required and times when sealer is recommended. Let's cover the different scenarios so you can be confident in whether you need a sealer for your next project.
Pavement Type
Concrete: If you're applying a preformed marking to concrete, you must use sealer no matter what kind of marking you are using. Concrete traps moisture and contaminants like salt, that will seep to the surface and could eventually cause the marking to pop loose. If you're applying a preformed marking to concrete, always use a sealer.
Asphalt: Asphalt can go either way. If the asphalt is new and the top layer still contains the asphalt oils, then you don't need a sealer but if you want to throw caution to the wind, it won't hurt anything if you do. However, if the asphalt is old and oxidized, then you do need a sealer. If you're installing a multi-color marking on asphalt, it is highly recommended that you use a sealer, regardless of the asphalt age.

Do You Need ViziGrip?
Unless otherwise noted, all PreMark thermoplastic markings come standard with glass beads embedded in the preformed template. If you need an anti-skid marking in addition to glass beads, you can choose to purchase the ViziGrip version.
ViziGrip® stands for "Visibility with Grip" and is a ready-made product from the factory that has glass beads along with a traction anti-skid aggregate.
ViziGrip is ideal for crosswalks where foot traffic is present, bike lanes where folks are riding over bike markings or for general markings where skidding might present a liability or be less than ideal and the best part, you can order it at no additional cost!
