A heavy-duty patch that performs in any weather

This versatile, fibered mastic gives you a reliable way to stop leaks, rain or shine. 

Ready Patch Fibered Sealant by Progressive Materials (PM) is a fibered mastic designed to stop leaks instantly, even during a storm or underwater. Its thick, trowel-grade consistency makes it easy to work into rough areas and hard-to-reach spots, from cracks in SPF to worn-out flashing around roof penetrations. Better yet, it adheres to virtually any surface, even wet substrates, making it a reliable go-to when weather conditions are less than ideal. 

RP 300 is extremely versatile and can be used for emergency roof repairs, sealing stubborn problem areas and everything in between. From patching granulated modified bitumen to direct-to-metal surfaces, aged single-ply membranes or drain bowls, this one-component elastomeric sealant delivers a strong, lasting bond without the need for primer or mixing. 

Common uses include: 

• Rough patches on spray polyurethane foam (SPF) 
• Sealing drains and rooftop-mounted equipment
