MonoBase Application Instructions
MonoBase is a water-based, acrylic, flexible, durable, & highly elastomeric waterproofing base, suitable for application over most low slope, metal, & other roofing substrates.
MonoBase is used in conjunction with MonoTop or HardTop to provide a single, watertight membrane.
- Clean & prepare the surface to receive waterproofing treatment by removing all loose & flaking particles, grease, & laitance with the use of a 3,000 PSI power wash & a stiff broom. Care should be taken not to inject water into the substrate during washing. In some cases, additional drying time may be required after the cleaning process.
- Brush apply MonoBase across the entire roof surface at a total rate of 25-40 sq. ft./gal, or 2.5 gal/sq., depending on the substrate.
- Embed suitable size fabric into the wet slurry, brushing out bubbles, creases, & fish mouths. Care should be given to ensure that adjacent runs of fabric overlap a minimum of 4”.
- Immediately apply a saturation coat of MonoBase by brush to the fabric at a coverage rate of 40sq ft/gal.
- Continue the MonoBase treatment up & over vertical surfaces, roof penetrations, & into roof drains, gutters, & scuppers.
