Mastic Polymère SP COLZINC Gris - Cartouche 290ml - Réf. 75029AE013

High modulus hybrid sealant

Formulated with hybrid polymers, this high modulus sealant cures by reaction with atmospheric moisture. It creates a resistant and durable joint for long-lasting assemblies.

Zinc & waterproofing applications

Specially designed for assembling and bonding zinc parts (new or old), repairing gutters and downspouts, sealing flashing strips and chimney bases.

Substrate compatibility

Optimal adhesion without primer on most substrates. Excellent performance with copper, lead, pre-coated aluminum, stainless steel and galvanized steel.

Instructions for use

Apply using a manual or pneumatic gun on clean, degreased surfaces, at temperatures between 5 and 35 °C. Remove any grease, paint or non-adherent coatings. Smooth with a damp finger or spatula immediately after application. Use the cartridge within 24 hours of opening. In cold weather, keep cartridges at 20 °C before use.

Cleaning & painting

Clean tools with EMFINET 683, methyl ethyl ketone or acetone while the sealant is not cured. Once hardened, proceed with mechanical cleaning. Water-based paints are compatible. For solvent-based paints, perform preliminary tests.
