What is the VOC content of Monolithic Membrane 6125 (MM6125)?
MM6125 contains no Volatile Organic Compunds (VOCs).
Can MM6125-FR be applied on plywood, cement or gypsum boards?
The primary acceptable substrates for Hot Applied Rubberized Asphalt are concrete, gypsum/cement type boards, and wood (plywood or wood planking). Please refer to the Membrane Assembly and Acceptable Deck Chart here.
How long can the protection sheet over the MM6125 membrane be left exposed to UV?
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.
What is the application temperature of MM6125?
MM6125 should be heated and melted in a rubberized asphalt melter (not a typical asphalt kettle) to an application temperature of between 356 and 375 degrees F (180 - 190 degrees C).
What is the thickness of MM6125-FR (Fabric Reinforced)?
MM6125-FR membrane is applied to a minimum thickness of 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.
Does Hydrotech have an FM approved assembly?
Yes, Hydrotech maintains FM Approval as a Class 1 Roof Cover for MM6125-FR. In such cases, the protection sheet must be Hydrocap 90 FR.
What are my surfacing options?
Options for typical Protected Membrane Roof (PMR) applications, also known as Inverted Roof Membrane Assemblies (IRMA), include stone ballast, architecturally finished concrete pavers, a concrete topping slab, or our Garden Roof® and Blue Roof components. Self-ballasted concrete surfaced Styrofoam panels called Hydroguard® are also available as an option.
