On the subject of our fine selection, we would like to draw your attention to the fantastic ClassicBond EPDM Water Cut-Off Mastic – the perfect choice for both professionals and homeowners looking to do a spot of DIY.

The ClassicBond EPDM Water Cut-Off Mastic is a one-component, self-wetting butyl-blend mastic which is designed to be used in conjunction with roofing and waterproofing systems. It boasts a low viscosity and is extremely tacky making it perfectly suited as a sealing agent between various membranes. Furthermore, it is useful for when a membrane is being terminated using a compression-type seal.

Due to it being tacky, the ClassicBond EPDM Water Cut-Off Mastic will remain as such even when used with compression-type terminations. It can also be used in parapet wall constructions too. Each tube provides a coverage rate of around 3 linear metres. This is based on the recommended application rate which is 11mm bead.

The ClassicBond EPDM Water Cut-Off Mastic has an effective service temperature of -40^oC to 93^oC and boasts an ‘excellent’ cold weather flex rating. As mentioned above, it sports a low viscosity (1,320,000 Cps) and boasts a shelf life of up to 1 year (unopened container). It’s worth noting that these values are intended to serve as a guide and may not be true across the entire range.

Application to an EPDM rubber roofing system or any other compatible roofing type is both easy and straightforward – even an amateur could do it. To successfully apply the ClassicBond EPDM Water Cut-Off Mastic to your roof, be sure to stick to the following steps:

1. Ensure that any surfaces on which the Water Cut-Off is to be applied are free from moisture, oil, dirt and other contaminants.
2. Apply an 11mm bead of Water Cut-Off. This is typically applied between the substrate and the edge of the membrane.
3. Finally, the correct termination material should be applied and secured to ensure that constant compression is maintained for the Water Cut-Off Mastic.

Care should be taken to avoid contact with the skin and eyes, and adequate ventilation should be present, so you do not breathe in the vapours. Please be advised that the ClassicBond EPDM Water Cut-Off Mastic is flammable so care should be taken to store the product away from potential ignition sources.
