Product Information

Full details

This 200kg pack of Cold Lay Macadam is an ideal solution for homeowners and professional contractors looking to perform quick, durable repairs on potholes, driveways, and paths. The primary benefit of this product is its ready-to-use formulation that eliminates the need for heating equipment, saving significant time during site preparation. However, it is important to note that this material is specifically designed for external use and requires thorough compaction to reach its full structural integrity.

FAQs

Does this product require a primer?

While not strictly required, ensuring the repair site is clean and dry is essential for proper adhesion.

Can I use this to pave a whole driveway?

This product is designed for repairs, patching, and maintenance of existing tarmac rather than laying a complete new surface.

How quickly can I drive on the repair?

The area can usually be opened to foot or vehicle traffic shortly after thorough compaction, though it may take time to fully cure.

Can this be used in freezing temperatures?

It is best applied in temperate conditions. If applied in extreme cold, the material may be harder to work with and compact.

What should I do with unused bags?

Keep the bags sealed tightly and store them in a cool, dry location to maintain the material's integrity for future use.

Troubleshooting

Material feels loose after application

The material has not been compacted sufficiently; ensure you use a heavy tamper or plate compactor to achieve proper density.

Macadam is not adhering to the existing surface

Check that the area was cleaned of all loose debris and dust; the surface must be free of contaminants for the material to bond correctly.

Setup, Compatibility & Care

To ensure optimal results, follow these preparation steps:

Preparation: Clean the area to be repaired by removing all dust, loose stones, and organic debris.
Application: Open the 20kg bag and distribute the contents evenly into the repair zone. If filling a deep hole, fill in layers of no more than 50mm, compacting each layer before adding the next.
Compaction: Use a professional-grade compactor or a hand tamper to firmly press the macadam down until it is flush with the surrounding surface.
Storage: Keep bags tightly sealed and stored in a cool, dry place away from direct sunlight until you are ready to begin work to prevent the material from hardening prematurely.
