Urochem 611
HI-BUILD WATERPROOFING & CHEMICAL RESISTANT COATING
DESCRIPTION
Urochem 611 polyurethane coating is a solvent free, two-part polyether-based coating. It yields an extremely flexiblehibuild product with good chemical resistant and elongation properties.
APPLICATION
• Mix the activator and the base separately before adding the activator to the base and mixing thoroughly for a minimum of 3 minutes with a paddle mixer. Apply a thin coat of primer by brush and allow the solvent to evaporate before applying coating or sealant. Once the primer loses its tackiness, re-prime.
• The self-levelling grade may be applied ion a single application by notched trowel or rake and rolled with a spiked roller to assist in the levelling process as well as to remove bubbles.
• Walls and sloping areas should be coated with the thixotropic grade using a brush or roller. Note two coats are recommended and the intercoat time must not exceed 24Hours.
SAFETY
