Roofing Felt Adhesive

Cromar Roofing Felt Adhesive is a cold-applied, solvent-based bituminous adhesive developed to bond consecutive layers of roofing felt to roofing felt, concrete, asphalt, wood or metal.

It is applied cold for easy and quick installation.

After applying to the surface, the adhesive should be left for approximately 15 to 30 minutes to develop its full thickness.

The drying time varies depending on the thickness of the adhesive used and the climate.

Application:

• Apply using either a stiff brush, mop or squeegee.
• Warm in a room overnight before use.
• It should be applied to the surface and left for 15 to 30 minutes (depending upon drying conditions) to develop its full thickness. The felt should then be placed into the wet adhesive film carefully, rubbing or rolling each section down to ensure maximum contact with the adhesive and to expel air trapped between the surface and the felt. Wherever possible, the felt should be unrolled into the roofing,
• The overlaps should be at least 75mm on the side and 150mm at the ends. Cromar Roofing Felt Adhesive can be applied to the underside of the felt and compacted to ensure a complete bond at the side and end laps.
• When used with a timber structure, the first layer of felt must be nailed down. Successive layers of felt may then be bonded using Cromar Roofing Felt Adhesive.
• When used on porous concrete surfaces, it will be necessary to prime the surface first, ensuring that the primer is completely dry before the first layer of felt is applied.
• Twenty-four hours after laying felt, check all bondings to ensure that full adhesive has been obtained. Particularly check all laps.
