How do I calculate the number of bags I need?
The amount needed depends on the desired layer thickness and the surface area to be covered. As a general rule, to achieve a decorative layer 4 to 5 cm thick, you will need approximately 1.5 20 kg bags per square meter (m²). We recommend measuring your area and consulting an aggregate conversion chart for an accurate calculation.
Does the color black fade in the sun or rain?
No. As it is a natural stone, the black color is intrinsic to its mineral composition. It is highly resistant to discoloration caused by prolonged exposure to UV rays or adverse weather conditions.
Is it suitable for areas with high pedestrian traffic?
The 20/40 mm pebble is suitable for pedestrian paths, but its comfort will depend on the thickness of the layer. For greater comfort, it is recommended to install a thicker layer (minimum 5 cm) and, if possible, use a weed barrier underneath to stabilize the surface and prevent excessive movement of the stones.
Do I need to install weed barrier fabric before laying the stone?
Although not strictly required, it is strongly recommended to install a geotextile weed barrier before spreading the gravel, especially if using it on soil. This effectively prevents weed growth from below and helps separate the aggregate from the substrate, keeping it clean and retaining its color for longer.
How should I clean the pebbles once they are installed?
Generally, occasional cleaning with a gentle pressure hose or light sweeping is sufficient. If leaves or organic debris accumulate, remove them periodically to prevent decomposition and slight discoloration of the stones.
