PRODUCT DESCRIPTION:

EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING is a solvent based, full-bodied, black, brushable bitumen compound with added fibres for reinforcement. It is an effective general purpose roof coating that is resistant to wash-off by rain almost immediately, and is therefore ideally suited for winter use. The product is specifically designed for general waterproofing in all roofing applications, guttering (non
plastic) and structural steelwork. Dries to a tough black coating.

USES:

EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOFCOATING may be applied by brush to waterproof and re-seal many different types of roof coverings, including:
1. Asphalt roofs.
2. Built-up felt roofs.
3. Concrete roof decks.
4. Asbestos-Cement sheeting.
5. Metal sheeting, including iron, steel, zinc and lead.
6. Slates, tiles.

EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING may be used in conjunction with a rot-proof hessian reinforcement scrim or bitumen coated glass fibre scrim such as a glass membrane.
EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING may also be used as a vapour barrier on walls and roofs.

APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
No roof coating product can be expected to repair an existing roof that is not structurally sound and stable. Before using a surface coating the roof structure should be inspected and, if necessary, put in order. All cracked, broken, slipped or missing slates, tiles, sheets or other forms of covering should be replaced or re-fixed, and cracks in felt or asphalt filled. Safety recommendation: do not coat roof lights, windows, glass or translucent sheets. These will constitute a
hidden hazard if disguised.
Preparation of the surface is of great importance and will influence the degree of adhesion and life of the renovation. All roof surfaces to be coated should be sound, stable and clean, i.e. free from loose debris, dirt, dust and grease. All traces of algae and fungal growth should be removed using a stiff bristle brush. Where algae and fungi have been present, remove them completely and treat the surface with EVERBUILD® FUNGICIDAL WASH to kill any remaining spores, thereby discouraging return of growth.

APPLICATION:
Note: These instructions follow the recommendations of the National Federation of Roofing Contractors Code of Practice governing the use of Liquid Coatings for Roof Waterproofing.

ASPHALT ROOFS
On asphalt roofs where blisters have occurred, these should be heated with a blow lamp until soft and then out. If the asphalt is crumbling or badly cracked it must be removed and replaced with a polyester based underlay and bonded to the roof deck.
EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING should be applied by brush in 2 coats, the first being allowed to dry before the second is applied.

BUILT-UP FELT ROOFS
Remove any loose chippings and carry out the preparatory work detailed above. Minor marks and defects will be effectively filled and covered by EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING, but where these are wider than 0.75mm they should first be filled with BLACK JACK® BITUMEN MASTIC and the
mastic allowed to dry. Blisters in roofing felt should be opened out, cleaned
with a stiff bristle brush and coated with EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING at 1.50 square metres per litre. This coating should be allowed to set until it is “tacky” and then the felt should be re-fixed by bonding it down.
In each case, further coats of EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING and a glass membrane should then be applied

REINFORCED CONCRETE
Carry out preparatory work. New decks should first be allowed to cure and then primed using BLACK JACK® BITUMEN AND FLASHING PRIMER at 4-6 square metres per litre (rate depending upon porosity).

LIGHTWEIGHT CONCRETE
Carry out preparatory work. Allow the concrete roof deck and topping screed to cure. A glass fibre felt underlay should be partially bonded to the surface using
BLACK JACK® ROOF FELT ADHESIVE. The felt should be lapped, sealed and adequate ventilation provided for the materials beneath it. EVERBUILD® BLACK JACK®
905 ALL WEATHER ROOF COATING and a glass membrane should then be applied.

ASBESTOS-CEMENT SHEETING
Carry out preparatory work. It is particularly important to ensure that the Asbestos-Cement is not saturated with water before protective coating commences.
Wait until the Asbestos-Cement sheeting is dry and then apply two coats of EVERBUILD® BLACK JACK® 905 ALL WEATHER ROOF COATING, each at 1m² per litre,
allowing the first coat to dry before application of the second.
