Vulkem 191 Primer VOC QD per 1 Gallon Unit

Vulkem 191 Primer is a quick drying, one-part, moisture-curing primer used as a urethane-to-urethane tie-in that prepares surfaces of cured Vulkem urethane sealants, coatings and membranes.

Application

• Porous surfaces, interlaminar, urethane sealants, coatings and TREMproof membranes
• It is used to prepare surfaces of cured urethane sealants, coatings and TREMproof membranes that will be sealed with a fresh coat.
• Apply with a clean brush or roller. Do not apply in excess or allow to puddle. Use a short nap roller only. Dry time is 15 to 30 min at 70 °F (21˚C).
• Apply coating or sealant within 1 to 2 hr on the application, when primer is still tacky, but does not come off substrate. Primer will yellow with time if left exposed.
• Do not apply in excess to other substrates not intended to be coated. Do not apply sealant or coating if primer becomes hard or glossy; if it does, clean with a Tremco approved solvent and reprime with Vulkem Primer #191 QD
