Waterproofing FAQ

The Volatile Organic Compound (VOC) content of Monolithic Membrane 6125 (MM6125) is zero (0). MM6125 contains no VOCs.

Monolithic Membrane 6125 (MM6125) should never be left exposed to UV.

The protection sheet over Monolithic Membrane 6125 (MM6125) can be left exposed to UV for up to 30 days, 6 months, or indefinitely, depending on the protection sheet used. Hydroflex 30 protection sheet should be covered with subsequent overburden within 30 days of installation. Hydrocap 90 may be left exposed up to 6 months and Hydrocap 160 may be left exposed indefinitely.

The application temperature of Monolithic Membrane 6125 (MM6125) is between 356 and 375 degrees F (180 - 190 degrees C). MM6125 should be heated and melted in a rubberized asphalt melter (not a typical asphalt kettle) to the application temperature mentioned above. 

MM6125 does not have a "cure" time. Technically, as a hot applied material, the membrane simply cools.

The thickness of Monolithic Membrane 6125-FR is 215 mils (approx 7/32", 5.5 mm). The total thickness is composed of an initial 90 mil thick coat of MM6125, into which is embedded a layer of spunbonded polyester, followed by a top coat of MM6125 at 125 mils thickness.

Yes, Monolithic Membrane 6125-FR can be submerged in water. MM6125 is a monolithically applied material that has no seams, the membrane can be in fully submerged conditions indefinitely and be fully guaranteed for watertightness.

The minimum slope required for Monolithic Membrane 6125 is 0. Technically, MM6125 is acceptable for no slope and low slope roofing applications and does not have a minimum requirement.
