PREPARATION & APPLICATION GUIDES
• Ensure the area where the Cold Lay Macadam is to be laid is dry and firm enough to support the weight of a car under normal conditions.
• Sweep the area and remove all weeds.
• Before overlaying concrete or paving, spray or brush on a tack coat of bitumen emulsion (edging & Jointing Spray is recommended) at a rate of about 0.5litres/m2 , to help prolong the life of the repair, especially if prone to freeze/thaw conditions.
• Use an ordinary rake, spade or trowel to spread the Cold Lay Macadam to the required thickness.
• Use a roller to achieve good compaction or, alternatively, use a heavy, flat object for ‘tamping’ to achieve similar results
• Wet the roller or tamper frequently to stop the Cold Lay Macadam sticking to the tool and ‘picking up’.
• Brush a little dry sand or dust over the surface after compaction to help prevent ‘picking up’ of the fresh material as it sets. This is not essential but may be helpful, especially on warmer days.
• When repairing deep pot-holes (greater than 30mm) lay the Cold Lay Macadam in two stages.
• Thoroughly compact the first layer before spreading the next layer and compact to bring the finished surface to the required level.
• Do not place heavy and sharp objects on the newly laid surface. • Protect from caravan legs, jockey wheels and other similar high loadings.
• It is not recommended to use Cold Lay Macadam in outside temperatures below 5oC or when the area to be worked is very wet.
• Clean all equipment and tools with water prior to the material setting. TYPICAL COVERAGE One bag of Cold Lay Macadam will cover approximately 0.4m2 at 30mm when compacted. PLEASE NOTE:
• After prolonged storage, it may be necessary to expose the bag of the Cold Lay Macadam to direct sunlight for 1-2 hours prior to opening to loosen the material and restore workability.
• The workability of the Cold Lay Macadam will improve if the outside temperature is above 10oC (50oF).
• The more rolling or tamping applied to the surface, the better the resulting surface finish.
• The material may be prone to marking during early life and warm conditions.
