Installation and care


Anthracite Slate paving is usually installed with a traditional sand and cement mix laid on a solid material like consolidated MOT.  We do not supply standard building materials like sand and cement.  You or your paving slab installer can easily source this locally from a builder's merchant or local DIY store. 


It is your choice to seal or not seal your limestone paving.  Untreated paving slabs will take on a life of their own after they have been exposed to the weather.  Sealing will help prevent the ingress of dirt and algae.


Any external grade wide-joint grout can be used.  Specific brush-in grouting systems have also been formulated for use with limestone paving. We recommend ProJoint Rapidflow Brush-In Porcelain Grout in Mid Grey.


Anthracite Slate paving slabs should be cleaned with proprietary patio cleaning products.  We do not recommend the use of acidic "patio cleaning" products that may damage the surface.  The use of high-pressure washers is acceptable as long as the pressure is kept away from grout joints.
