SkyGuard EPDM Bond & Seal Mastic is a strong, easy-to-use roofing adhesive and sealant designed for bonding SkyGuard EPDM membrane around the perimeter of a roof deck, helping to create a secure and watertight finish.
Supplied in a convenient 300ml cartridge, Bond & Seal Mastic can be applied straight from the tube using a suitable sealant gun. With coverage of approximately 10 linear metres per cartridge, it provides a simple and cost-effective solution for securing EPDM membrane around roof edges.
Developed with homeowners and novice DIY installers in mind, SkyGuard Bond & Seal Mastic forms an essential part of the complete SkyGuard EPDM rubber roofing system.
SkyGuard Bond & Seal Mastic is designed to bond and seal the EPDM membrane around the perimeter of the roof deck.
While SkyGuard Water Based Deck Adhesive is used to bond the main area of membrane to a suitable timber roof deck, Bond & Seal Mastic is used around the roof edges to ensure the membrane is securely bonded and the perimeter is properly sealed.
Typical applications include:
Each 300ml cartridge covers approximately 10 linear metres.
As Bond & Seal Mastic is applied around the roof perimeter, the amount required can be estimated by calculating the total length of the roof edges.
For example, a typical 2.44m x 1.83m (8ft x 6ft) shed roof has a perimeter of approximately:
2.44m + 2.44m + 1.83m + 1.83m = 8.54 linear metres
One 300ml cartridge, with approximately 10 linear metres of coverage, should therefore be sufficient for a typical 8ft x 6ft shed roof when applied in accordance with the manufacturer’s instructions.
Actual consumption may vary depending on application.
SkyGuard Bond & Seal Mastic has been developed to make installing an EPDM roof straightforward for homeowners and competent DIY installers.
The product can be applied straight from the cartridge, making it easy to create a consistent bond around the perimeter without specialist adhesive application equipment.
It is particularly suitable for projects such as:
For a typical 8ft x 6ft shed, one 300ml cartridge is recommended.
Both products perform important but different jobs within the SkyGuard EPDM roofing system.
SkyGuard Water Based Deck Adhesive is used to bond the main area of EPDM membrane to a suitable timber or OSB3 roof deck.
SkyGuard Bond & Seal Mastic is used around the perimeter of the roof, securing and sealing the membrane at the roof edges.
Using both products in their intended locations helps ensure that the membrane is securely bonded across the deck and properly finished around the perimeter.
SkyGuard Bond & Seal Mastic is designed to be used alongside the other components within the SkyGuard EPDM rubber roofing system.
When correctly installed with the appropriate SkyGuard membrane, deck adhesive and accessories, the system can create a durable and watertight flat roof with a life expectancy of up to 50 years.
Using the correct products at the main roof deck and perimeter helps maximise the long-term performance of the complete EPDM roof.
Roof edges are a critical part of any EPDM installation, and correctly securing the membrane around the perimeter helps create a reliable and long-lasting finish.
SkyGuard EPDM Bond & Seal Mastic 300ml provides a simple solution specifically designed for this part of the installation. With straightforward cartridge application and approximately 10 linear metres of coverage per tube, it is particularly well suited to DIY shed roofs, garden buildings and other small flat roofing projects.
