Tools

Use a spray gun to obtain the smoothest finish. Add 5% water if necessary for spraying. A foam brush or a roller followed by a foam brush to level out the coating can be used. A ¼ in. nap 6 mm Lanilla Specialty Mohair Roller manufactured by Wooster works excellent for obtaining an ultra-smooth surfaces approaching that what is achieved by spraying.

Wearlon® 2020.90 Primer

(Wearlon® 2020.90 is used only when necessary on surfaces that are difficult to adhere to.) Avoid diluting if possible. Add 5% water if necessary for spraying. Addition of 30 % water is used in extreme cases when roll coating on hot surfaces. Note: Whenever possible apply Wearlon® under room temperature conditions. Do not apply at temperatures below 40°F and relative humidity above 90%

1. Read MSDS and Data Sheet for Wearlon® 2020.90 prior to application.
2. Clean surfaces with drinking water while making sure there are no residual oils or grease clinging to the surface to be coated.
3. Shake all containers to make sure these coatings are homogenous.
4. Add the amber colored Wearlon® 2020.90-B to the respective Wearlon® 2020.90-A. Shake or mix well before using. For less than the pre-packaged kit, mix as follows: To 11 parts of the A component, mix in 2 parts of the B component. Use up the catalyzed mixture within one hour after mixing. Always clean up immediately with water before coating cures. The coating should be clear and no longer have a milky appearance.

Allow the Wearlon® 2020.90 coating to harden for at least 20 minutes to an hour before applying the Wearlon® 722.

Wearlon® 722

1. Read MSDS and Data Sheet for Wearlon® 722.
2. Mix and apply a light coating of the Wearlon® 722. Allow at least one to two hours to cure before applying Wearlon® 711. Always clean up immediately prior to the coating setting up and becoming water resistant.

** Always make sure the desired appearance is achieved if you will be applying an additional top coat. Sanding or a second coat may be required before application of top coat.

Wearlon® 711

2. Add the Wearlon® 711-B acid catalyst to the Wearlon® 711-A. To ensure a good homogenous mixture, mix periodically before and while applying. Use within 6 hours after mixing the A and B components together.
3. Apply a light coating of the catalyzed Wearlon® 711 over the Wearlon® 722 /Wearlon® 2020.90 surface. Allow at least two hours to cure or set up prior to subjecting to any abrasion. Clean up is achieved using water. Always clean up immediately prior to the coating setting up and becoming water resistant.
