zerogreen® stone adhesive - FAQ

Before you start consolidating the stones, prepare the subsoil by excavating it to the required depth and compacting it. You should also use weed control fabric as a separating layer.

Mix your clean and dry chippings/gravel with the zerogreen® stone adhesive in a clean container. You can use a forced action mixer or a concrete mixer for this. Follow the instructions on the packaging.

Approximately 24 hours, the actual time depends on the weather and climate. The surface should be protected from moisture for at least 24 hours during the curing phase.

The solid connection of the stones forms a barrier that prevents weed seeds from penetrating. This effectively prevents weed growth on your chippings and gravel surfaces.

By clean and dry grit or gravel we mean material that is free of dirt, dust and moisture. The cleanliness of the material is important to ensure optimal adhesion of the zerogreen® stone adhesive. Dust and dirt can impair the bond between the adhesive and the stones. So if you want to use your old gravel or unwashed grit, you should wash and dry it first.

You can use zerogreen® stone adhesive on all chippings and gravel surfaces around your home. It is ideal for garden paths, patios, gravel beds, verges, tree pits or other areas with gravel and chippings. However, it is not suitable for use by cars.

Yes, our stone adhesive is suitable for all types of chippings and gravel surfaces. It is designed to work with chippings or gravel up to 32mm in size. This allows for a wide range of applications from fine chippings to coarser gravel. However, please note that coarser material may require more adhesive to ensure full coverage and a permanent bond.

One container of our stone adhesive can be mixed and processed with up to 75 kg of chippings/gravel. The number of containers you need depends on the size, depth and condition of your area.

Yes, you can seal chippings and gravel surfaces, and our zerogreen® stone adhesive is ideal for this. It acts like a sealant by firmly bonding the stones together and creating a stable, non-slip and weed-free surface. This type of 'sealing' has the advantage of preserving the natural look and feel of the stones, while at the same time offering the functionality and ease of care of a sealed surface. In addition, the surface remains permeable to water, which ensures good drainage and prevents waterlogging."

Maintaining your chippings or gravel surface that has been solidified with zerogreen® stone adhesive is straightforward and requires little effort. Simply sweeping or spraying with water is enough in most cases to remove dirt, as the solid bond between the stones prevents dirt from penetrating deep into the surface. In the event that green deposits, algae or fungi form on your surface, we recommend using one of our zerogreen® green deposit removers. These are specially designed for our products and effectively and gently remove green deposits and other organic dirt without affecting the strength of the stones.
