Envirograf Flexible Sealant Kit for Pipes and Cables

About Flexible Filler Kit for Pipes and Cables

The kit is designed for use in both plasterboard and solid substrate surfaces i.e. brick, block and concrete walls and ceilings. Both EN/F cartridge types are water-based materials, but they become water-resistant once cured. Tested in a plasterboard wall, achieving 96 minutes fire rating. The kit comprises three 310ml tubes of water-based sealant (two tubes of dark grey sealant and one white finishing sealant).

• Suitable for use with aluminium, copper, plastic and steel pipes up to 50mm diameter
• Can also be used for cables (including armoured cables, MICC and flexible cable types) up to 32mm diameter
• EN/F2, our white intumescent sealant, is ideal for use as a decorative finish and comes as part of the EN/F Kit
• Both EN/F sealant types are made of water-based materials which become water-resistant once cured

Application

The cartridges marked EN/F1 (the dark grey intumescent graphite compound) are for filling around theservices from 30mm into the hole and up to 10mm from the front surface.

The cartridge marked EN/F2 (the white intumescent sealant) is used to fill the gap from the grey material to the front surface of the plasterboard or block wall.

The surface can then be levelled using a decorator’s spatula. Once cured, the surface material can be painted.

Plasterboard:
In plasterboard walls the hole must be 40mm larger in diameter that the services passing through. For example, a 50mm diameter pipe would require a hole size 90mm in diameter.

Solid Substrate:
For brick, block and concrete ceilings and walls the hole must be 30mm larger in diameter than the service. For example, a 50mm diameter pipe would require a hole size 80mm in diameter.
