Black Jack Roofing Felt Adhesive is a cold applied, black oxidised bitumen-based cold felt roofing adhesive used to bond roofing or glue roofing felt to itself, concrete, asphalt, metal, wood and similar surfaces. Also suitable for use as a cold gritting solution.


  • High bond strength roof felt adhesive 
  • Also suitable for gritting

Areas For Use

  • Roof felt glue - Bonding all types of roofing felts to metal, concrete, roofing felt, wood
  • Shed felt adhesive
  • Sealing roofing felt laps
  • Bonding Chipping’s to the final layer of felt


  • Do not use in areas where subsequent solvent contact is likely.
  • Avoid inhalation of vapours in confined spaces.
  • On timber roof structures, the first layer of felt must be nailed down to comply with BS 8217:1994 the second and third layers may be bonded with Black Jack Roofing Felt Adhesive.

Surface Preparation
Ensure that the surface to be repaired is dry and clean, i.e. free from all loose debris, rust, dirt and grease.  All traces of algae and fungus growth should be removed using a stiff-bristled brush.  Where algae and fungi have been present, remove all traces completely and treat the surface with Everbuild Fungicidal Wash in order to kill any remaining spores, thereby discouraging the return of the growths. Porous surfaces may be primed with a coat of Black Jack Bitumen Primer and allowed to dry before proceeding.

In general, the felt laying techniques employed should be those detailed in BS 8217:1994. Black Jack Roof Felt Adhesive should be brush or mop applied to the surface and left “open” for 15 to 30 minutes before the roofing felt is placed into the wet adhesive film carefully, rubbing or rolling each section down to ensure maximum contact with the adhesive and ensuring that all air has been excluded.  The felt should then be weighted down until the felt has adhered to the surface.  Whenever possible, the felt should be unrolled into the adhesive and rolled home with a lighter roller (approx. 25kg).

As Lap Cement
Laps at the edges should be at least 75mm wide and laps at roll ends should be at least 150mm.  Laps and final edges should be liberally treated on their underside with Black Jack Roof Felt Adhesive and well compacted.

Timber Roofs
On timber roof structures, the first layer of felt must be nailed down to comply with BS 8217:1994 the second and third layers may be bonded with Black Jack Roof Felt Adhesive.

Concrete and Lightweight Concrete Screeds
As they are often extremely porous, these surfaces will require a priming coat to ensure successful adhesion of Black Jack Roof Felt Adhesive.  Prime with Black Jack Bitumen and Flashing Primer.  It is essential that the primer has completely dried before the first layer of felt is applied.

After Care
Twenty four hours after laying, check all bonding to ensure that full adhesion has been obtained.  Particularly check all laps if in doubt, press home or roll any felt that appears to be lacking full adhesion.

As a Cold Gritting Solution
Black Jack Roof Felt Adhesive is suitable for use as a gritting solution for roofs with up to a 10° slope.  The roof surface should be clean and free from dirt, dust and all loose debris.  The surface should be preferably dry although the felt adhesive may be applied to damp, but not wet or waterlogged surfaces.  The compound should be spread evenly direct form the container in convenient areas of 20 square metres at a time.  Do not allow the film to form a puddle or become too thin.  The chippings should be applied immediately into the wet film.  Care should be taken not to over-chip and to ensure that the Chipping’s cover the film shoulder to shoulder.  Proceed to the next area. Leave the completed surface dressing for at least 72 hours and then lightly brush off any excess chippings.  Do not leave any black film exposed.

Cleaning Tools
Tools may be cleaned with paraffin or white spirit.  Spillages should be wiped off surfaces before the felt adhesive has set.

Black Jack Roof Felt Adhesive contains a flammable solvent and all normal precautions against fire must be taken during both storage and use.  Store in original container in cool dry conditions.  Keep away from sources of ignition.

Shelf Life
Storage life 24 months in tightly sealed undamaged containers.
