Multicrete All Weather Roofing Compound - 5 or 25L
A solvent based, cold applied bituminous compound containing a small amount of organic fibre to add strength and stability. An effective, general purpose roof coating that is resistant to water almost immediately after application, therefore ideally suited for winter use. MulticreteTM All Weather Roofing Compound may be used to reseal, waterproof and repair many different types of roof coverings, including:
Built-up felt roofs
Concrete roof decks
Metal sheeting including iron, steel, zinc and lead
Slates and tiles.
MulticreteTM All Weather Roofing Compound may be used in conjunction with a rot-proof hessian reinforcement scrim or a bituminised glass fibre scrim. It may also be used as a vapour barrier. MulticreteTM All Weather Roofing Compound is not suitable for use in silage pits.
Method of Application
By Brush or Spray.
No roof coating product can be expected to repair an existing roof which 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.
Care needs to be taken over preparation of surfaces before application and will influence the degree of adhesion and life of the renovation. All surfaces must be free from oil, dirt, dust and loose debris. All traces of algae and fungus growth should be removed using a stiff brush and the surface treated with a fungicide to kill any remaining spores thereby discouraging the return of any growths.
MulticreteTM All Weather Roofing Compound should normally be applied in two coats at 1-1.5m² per litre depending upon the porosity of the surface.
Tools may be cleaned with white spirit. Minor spillages should be wiped off surfaces before the All Weather Roofing Compound has set. Major spillages should be mopped up immediately with an inert, absorbent material, such as sand, and disposed of in accordance with regulations.
Minimum 12 months in undamaged, tightly sealed containers. MulticreteTM All Weather Roofing Compound should be stored indoors away from all sources of ignition, naked flames, hot lights etc.
Health & Safety
MulticreteTM All Weather Roofing Compound is solvent based and gives off an inflammable vapour. The solvent may have a narcotic effect if inhaled or absorbed through the skin. In extreme cases contact with the skin may cause dermatitis. In case of fire use dry powder, carbon dioxide (CO2), foam, sand or earth. Never use water as this may spread the fire. Therefore the following precautions are advised:
- Wear protective clothing
- Avoid smoking, hot lights, naked flames or creating sparks
- Never ingest, wash hands thoroughly before eating or drinking
- Avoid contact with the skin, eyes and non protective clothing. Remove skin contamination immediately with a proprietary hand cleaner and wash with soap and water.
- When working with the product, until it has dried, ensure that the area is well ventilated thereby avoiding build up of solvent vapour.
- Do not apply to rooflights, windows, glass or translucent sheets as they will constitute a hidden hazard.
