Method of Application
By stiff brush, mop or squeegee. To avoid thickening in cold weather, store Multicrete Cold Gritting Solution in a warm room overnight prior to use.
Instructions
Multicrete Cold Gritting Solution is suitable for roofs with up to a 10slope. All surfaces must be free from oil, dirt, dust and loose debris. The surface should be preferably dry although the product may be applied to a damp but not wet or waterlogged surface. The compound should be spread evenly direct from the container in convenient areas of 20m² at a time. Do not allow pooling of the solution or the covering to be 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 chippings cover the film shoulder to shoulder. Proceed to the next 20m² area. Leave the completed areas for at least 72 hours and then lightly brush off any excess chippings. Do not leave any black film exposed.
Coverage
Coverage is dependent upon the size of the chippings to be bonded.
Chippings sized 3-9mm - 1.8m² per litre
Chippings sized 12mm - 1.3m² per litre
Cleaning Tools
Tools may be cleaned with white spirit. Minor spillages should be wiped off surfaces before the solution has set. Major spillages should be mopped up immediately with an inert, absorbent material, such as sand, and disposed of in accordance with regulations.
Storage Life
Minimum 12 months in undamaged, tightly sealed containers. Containers must be kept sealed and stored away from sources of heat and ignition.
Health & Safety
Multicrete Cold Gritting Solution 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:
1. Wear protective clothing
2. Avoid smoking, hot lights, naked flames or creating sparks
3. Never ingest, wash hands thoroughly before eating or drinking
4. 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.
5. When working with the product, until it has dried, ensure that the area is well ventilated thereby avoiding build up of solvent vapour.
6. Do not apply to roof lights, windows, glass or translucent sheets as they will constitute a hidden hazard.
