Contact your local sales representative for project specific recommendations.
Prior to proceeding, existing moisture should be removed and the surface should be wiped with a compliant, non-alcohol based solvent or other approved cleaner. Contact Technical Services for recommendations. Allow the solvent to flash dry. Prime using either Vulkem 191 Primer or TREMprime Multi-Surface Urethane Primer. Primer selection is driven by local compliance and regulations and secondarily by contractor preference. Apply primer at recommended coverage rates found on the primer selection guide on the website. Dry times will vary by primer and will also be affected by temperature and humidity conditions. Vulkem 191 Primer should dry to a "tack" and Tremco Multi-Surface Urethane Primer should be allowed to fully dry prior to proceeding with application of the subsequent Vulkem coating. Please consult Tremco’s Technical Services team.
The service temperature range for traffic coatings is -40°F to 185°F (-40°C to 85°C).
