APPLICATION
USES
KNIGHTSHIELD KS-5100 is recommended as a protective coating for both new and existing roofs. KNIGHTSHIELD KS-5100 bonds to all types of aged membranes*, sprayed-in-place polyurethane foam roofing systems, elastomeric roof coatings, concrete, plywood, and coated metal, on low slope or slopedroofs.
PACKAGING

- 1Gal. (3.8 L Cans) (2 Cans/Carton)
SHELF LIFE
Twelve months from date of manufacture in the original, unopened container stored below 90° F (32° C). Subject to re-inspection thereafter. Store in dry, shaded conditions away from sources of heat or ignition
APPLICATION METHOD
All surfaces to be coated must be clean, dry and frost-free. A 25-mil thickness at 77° F and 50% RH will skin over in approximately 60 minutes and have sufficient strength to walk on after approximately 4 - 6 hours. Times will be longer in dry climates
MIXING
Mix with a properly sized agitator (300 – 400 rpm) for a minimum of five minutes to ensure an even consistency of coating is obtained without air in suspension.
APPLICATION METHOD
The temperature of the surface to be coated should be between 35° and 120° F (2° and 49° C) and environmental temperature should be at least 5° F (3° C) above the dew point prior to and during application. When working in high humidity and/or high temperature environments, it is recommended to use a pail lid adapter fitted with an agitator. This will prevent the product from skinning over and curing in the pail during application. Coating has resistance to light rain one hour after application with temperature at 77° F (25° C) and 50% RH. It is recommended that KNIGHTSHIELD KS-5100 be applied using a 1 ¼” nap roller or an airless sprayer; however, brush and squeegee are also suitable methods of application.
