How To Apply Everbuild Black Jack 903

EVERBUILD BLACK JACK 903 BITUMEN TROWEL MASTIC is ready for use and should not be thinned.

Apply by steel trowel or putty knife.

CRACKS AND HOLES

Force the compound into the crack, but finish with a 25mm band at a 3mm thickness running the length of the crack. For large cracks and holes, apply the compound over the area to be treated and embed a closely woven glass fibre membrane into the compound to overlap the crack or hole by 50mm. Allow to dry and then apply a second coat, fully covering the reinforcing membrane.

CORRUGATED IRON/FIBRE CEMENT SHEETING

Tighten loose hook bolts and trowel around with mastic. Remove loose screws, re-bed screws and washers in EVERBUILD BLACK JACK 903 BITUMEN TROWEL MASTIC and tighten. Top seal in further mastic and trowel to a smooth finish. If the sheet is cracked, clean and prime with BLACK JACK BITUMEN FLASHING PRIMER and apply a bandage strip of glass fibre embedded in the mastic. When dry, overcoat with BLACK JACK BITUMEN /FLASHING PRIMER followed by BLACK JACK BITUMEN PAINT. Use the same technique for sealing side and end laps in corrugated sheeting.

TILES

Point up butt edges of ridge tiles, fillets and slates with EVERBUILD BLACK JACK 903 BITUMEN TROWEL MASTIC.

LEAD AND ZINC

Trowel over cracks and pinholes, where necessary, reinforcing with a woven glass membrane, fully embedded and covered.

FELT ROOF

Re-adhere loose felt using BLACK JACK ROOF FELT ADHESIVE. Apply EVERBUILD BLACK JACK 903 BITUMEN TROWEL MASTIC and overcoat with BLACK JACK ALL WEATHER ROOF COATING. Note: felt must be completely dry before applying the mastic.
