Applying Felt Adhesive

You must apply felt adhesive either using a stiff brush, mop or squeegee. To avoid thickening in cold weather, stock the felt adhesive in a warm room before — for more straightforward application.

Cromar Roofing Felt Adhesive, in particular, 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 highest 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 felt adhesive and rolled with a light roller (15 to 25kg).

The overlaps should be at least 75mm on the side and 150mm at the ends. To ensure a complete bond at the side and end laps, Cromar Roofing Felt Adhesive can be applied to the underside of the felt and well compacted.

When using 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 concrete surfaces that are porous, 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. Mainly check all laps.
