BITUTHENE® Solvent Primer is a bitumen-based primer in solvent which is specifically formulated to provide good initial adhesion and, more importantly, excellent, permanent adhesion of BITUTHENE® Waterproofing Membranes under many kinds of conditions.

Product Uses

BITUTHENE® Solvent Primer is used to prime all structural concrete, masonry or wood surfaces on which BITUTHENE® Waterproofing Membranes are to be applied. BITUTHENE® Solvent Primer is an integral part of the BITUTHENE® Waterproofing System. Sufficient primer must be used on the dry surface to condition it to a dust-free state that is suitable for the application of BITUTHENE® Waterproofing Membranes.

Application

BITUTHENE® Solvent Primer may be applied by spray, roller or brush. Use a heavy nap roller with natural material such as lamb’s wool to avoid deterioration.

Apply BITUTHENE® Solvent Primer to clean, dry, dust-free and frost-free surfaces at a coverage 6 to 8m2 / L. Deep puddles of primer should be avoided as this will lengthen drying time. Rollers or brushes should be dipped into pans to avoid pouring primer directly on the deck and creating puddles.

Allow BITUTHENE® Solvent Primer to dry one hour, or until tackfree. On warm days drying may require as little as 30 minutes.

Priming should be limited to what can be covered with BITUTHENE® Waterproofing Membrane in a working day. Any areas not covered with membrane during the day must be reprimed. Be sure to cover open pails when not applying primer.

Clean tools with mineral spirits or paint thinner at the end of each day. Rollers can be wrapped tightly overnight in plastic film or release paper from BITUTHENE® Waterproofing Membrane. (Mineral spirits and paint thinner are combustible liquids and should be used with care in accordance with the safety instructions of the manufacturer.)
