Extra Blue 4 Sides Cut Labradorite Cobblestone is recommended for exterior road paving, alleys, squares, backyards, heavy-traffic pedestrian areas, and low traffic.
Features
Labradorite is an igneous rock mainly composed of feldspar and formed when liquid magma slowly freezes into solid rock, just like granite, which gave its trade name.
As a result, its main feature is "labradorescence", an iridescence caused by light diffraction, and perceived by the viewer as a brilliant play of colors. This takes place due to a special light reflection in planes oriented in one direction.

How to lay out the cobblestone
Cobblestone is laid out over a sand/concrete underlay. For the latter, you will first need to apply adhesive all over the concrete screed. Then, apply adhesive over the cobblestone, and use the rubber mallet for laying it out, until reaching the perfect levelness that will allow a perfect rainwater run-off. In the end, place grout into joints and make sure this is waterproofed.
Maintenance
All surfaces must be sealed with professional solutions (LTP Mattstone, LTP Mattstone H20, LTP External Stone Sealer, or LTP Colour Intensifier) and cleaned with professional cleaners (LTP Grout Stain Remover, LTP Ferrex, and LTP Cement Grout & Salt Residue Remover).
