PRODUCT DESCRIPTION
Vulkem 350R is a UV stable waterproofing system, suitable for use with light to moderate pedestrian foot traffic. It is comprised of a tough curing, UV stable liquid polyurethane top coat and flexible polyurethane base coat. Different slip ratings can be achieved using the Vulkem 350R/346 system, by adding Tremco’s various aggregates to the Vulkem 346 top coat.
FEATURES & BENEFITS

- Easy to clean, waterproof system.
- Single component, UV top coat and base coat provides additional time savings on site.
- Single component system provides an efficient use of material for small areas.
- Fast cure through time allows the area to be returned to use 12 hours after installation in most instances.
- Mildew- and fungus- resistance safeguards concrete surfaces against environmental contaminants.
- Excellent durability and UV resistance extend the useful life of pedestrian systems.
- Re-coatable and compatible with other Tremco sealants, which enhances waterproofing protection with full system compatibility.
PRODUCT COATING APPLICATION
- Vulkem 350R should be mixed with a suitable electric paddle mixer at a rate of 500rpm for a minimum of 3 minutes, ensuring there is no settlement at the base of the drum.
- Apply Vulkem 350R at rate of 1.08m2/L or 0.93mm WFT to the entire area to be coated, including overall detail coats, but excluding expansion joints. The recommended method of application is with a notched squeegee. Cross-rolling may follow in the event the coating
needs to be leveled. Vulkem 350R can be applied with a solvent resistant, medium-nap (9.5mm to 12.7mm) roller sleeve.
- Allow Vulkem 350R to cure a minimum of 12 hours and a maximum of 24 hours. Cure rates depend on temperature and humidity. Refer to cure rate guidelines in the chart at the end of this document. If the Vulkem 350R has been applied for 24 hours or longer during the ideal temperature application range, it should be cleaned with a damp cloth of Tremco Xylol (do not saturate it) and re-activated with Vulkem 191QD re-activation primer.
