IMPORTANT
TESCON PRIMER RP penetrates into the sub-surface of porous substrates locking up loose particles and creating a highly adhesive substrate for the TESCON EXTOSEAL to be applied to. TESCON EXTOSEAL can also be applied while the TESCON PRIMER RP is still tacky or is fully dry. ORCON CLASSIC glue can be used as a primer and is recommended when sealing to uneven and porous masonry surfaces.

Recommendations and requirements
• TESCON EXTOSEAL self-seals around penetrations such as screws used for window installation. Any damage or tears should be patched using TESCON EXTOSEAL and/or TESCON EXTORA. • TESCON EXTOSEAL has a 180 days UV exposure limit prior to cladding. • TESCON EXTOSEAL can also be used behind cladding brackets or cavity battens to seal penetrations through weathertightness membranes. • TESCON EXTOSEAL can be used as a pliable flashing tape moulded around three-dimensional junctions with a reliable level of weathertightness performance.
