METHOD OF USE

Surface Preparation
Correct preparation is essential for the successful application of coatings such as ALL WEATHER ROOFING COMPOUND.
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.
Roof surfaces to be coated should be dry, sound, stable and free from loose debris, dirt, dust and grease. All traces of algae and fungi must be physically removed and the area then treated with FUNGICIDAL WASH.
ASPHALT ROOFS On asphalt roofs where blisters have occurred, these should be heated with a blowlamp until soft and then smoothed out. If the asphalt is crumbling or badly cracked it should be replaced.
ALL WEATHER ROOFING COMPOUND is 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 preparatory work as detailed above. Minor marks and defects will be effectively filled and covered by the ALL WEATHER ROOFING COMPOUND coating but where these are wider than 0.75mm they should first be filled with MASTERBUILD’S BITUMEN MASTIC and the mastic allowed to dry.
Blisters in roofing felt should be opened out, cleaned with a stiff bristled brush and coated with ALL 
WEATHER ROOFING COMPOUND at 1.5m per litre. The coating should be allowed to set until it is tacky and then the felt re-fixed by nailing it down.

Reinforced Concrete:
Carry out preparatory work. If the deck is new it should first be allowed to cure and then primed
using MASTERBUILD’S BITUMEN PRIMER at 6 – 8 m per litre.

Lightweight Concrete:
Carry out preparatory work. Allow the structure to cure. A glass fibre felt underlay (complying with BS747 Part 2 : 1970 Class 3B) should be partially bonded to the surface using MASTERBUILD’S FELT ADHESIVE. The felt should be lapped, sealed and adequate ventilation provided for the materials beneath it. ALL WEATHER ROOFING COMPOUND 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 sheeting is dry and then  apply one coat of MASTERBUILD’S BITUMEN PRIMER. Allow the primer to dry and then apply 2  two coats of ALL WEATHER ROOFING COMPOUND each at 1m per litre, allowing the first coat to dry before application of the second.

Metal Surfaces:
Any rust on the surface should be removed by wire brushing and then treating the metal with an
appropriate rust inhibitor such as MASTERBUILD’S PAINTS RED OXIDE PRIMER. ALL 
WEATHER ROOFING COMPOUND is then applied in 2 coats at 1.5m per litre per coat. Slates and Tiles:
Carry out preparatory work and re-fix any loose or damaged slates or tiles. Apply ALL WEATHER ROOFING COMPOUND incorporating a fibreglass membrane.

Application of Reinforcing Membranes:
Use of a reinforcing membrane is recommended in all cases where roofs are in a poor condition, in order to bridge cracks and fissured and provide a long lasting repair.

Having prepared the surface apply a first coat of ALL WEATHER ROOFING COMPOUND at 1m per litre and immediately roll in the glass fibre membrane ensuring it is well embedded into the coating without trapping air.
The membrane should be lapped by 50 – 75mm and the inside of each lap painted with ALL WEATHER ROOFING COMPOUND. Small gaps and differences in levels should be bridged ensuring that the membrane is not stretched too tight to allow for structural movement. At walls and parapets, continue the membrane vertically for at least 150mm and secure using self adhesive 150mm wide flashbanding, allowing 75mm to be in contact with the brickwork above. Apply a second coat of ALL WEATHER ROOFING COMPOUND and allow this to dry.

Final Treatment:
For maximum durability the top surface should be treated with either stone chippings or a solar
reflective finish to avoid an exposed black bituminous surface, Using ALL WEATHER ROOFING
COMPOUND, a third and final coat should be applied at 1.5m per litre and while still tacky the film is blinded with 1 – 2mm stone chippings. Alternatively the final ALL WEATHER ROOFING COMPOUND coating should be allowed to weather for 2 – 4 weeks and then a solar reflective coating applied using MASTERBUILD’s SOLAR REFLECTIVE PAINT.

CLEANING OF TOOLS
Immediately after use all tools and mixing equipment should be cleaned with White Spirit
