Fire Resistant Board Installation Guide

Installation

Ensure all service penetrations are complete and installed to the manufacturers recommendations. Remove dust and debris by brushing out the opening and surrounding area.

Apply masking tape around the face of the aperture, approximately 50mm from the opening any penetrating services should also be masked at 150mm from each face of the fire seal board.

Measure the overall dimension of the aperture and cut the board to suit ensuring a good friction fit using a sharp knife or padsaw.

Brush apply Intuchem board coating to all internal surfaces within the aperture and to all contact surfaces on any penetrating services.

Carefully fit the pre-cut board into the aperture, ensuring that all board to board surfaces are also adequately coated with Intuchem board coating Coat (so that the coating acts as an adhesive at all joints).

Seal any gaps between the services and the board and between the board and surfaces of the aperture with Intuchem coating.

Apply a brush coat of Intuchem coating (800 microns wft) to all services for a distance of 150mm from the board surface and 50mm around the edge of the aperture.

For floor application

Pour or trowel Intuchem fire rated mortar mix onto the mineral fibre shutter and build up to the required thickness with further applications.

To make the Intuchem fire rated mortar pour clean potable water into suitable mixing vessel and add sufficient dry Intuchem fire rated mortar to achieve the required consistency, stirring the slurry to remove all lumps.

The normal mixing ratios are:

2.5 parts FR Mortar : 1 part Water Pourable mix
3 parts FR Mortar : 1 part Water Trowelable mix
4 parts FR Mortar : 1 part Water Hand Batch mix
