Installation & maintenance... Delabole Slate Paving can be traditionally laid on a 2” (50mm) “dry” mix sand and cement screed. To improve adhesion paste the back with a neat slurry of cement or waterproof PVA.
Lay with slight fall away from buildings and towards drainage to ensure the area paved sheds rainwater. This will minimise the build up of algae and maintain a good slip resistance.
Where cutting is required, use a portable circular saw or angle grinder with a diamond blade. Use water to cool the blade, minimise dust generation and lubricate the cutting when possible. Wear a dust mask if dust occurs.
For grouting we recommend 15 - 25mm wide joints filled with Wide Joint Flexible Stone Grout or 50/50 mix of sharp sand and cement with waterproofer addded.
Cleaning... Keep paving clean when laying and grouting by wiping with a clean damp (squeezed out) sponge. Once dry, floor can be cleaned with soapy water.
Aftercare... Wash down occasionally to remove any deposits from trees & birds and to keep the paving free from algae.
Slip Resistance... All Delabole Slate Paving products have a high slip resistance and are suitable for all areas wet & dry. Any reduction of slip resistance is usually due to the presence of algae. It is good practice therefore, to wash down once or twice a year with the addition of an algae erradicator. We stock Lithofin Algex for this purpose but if not available and almost as good, wash down with a cupfull of household bleach to a bucket of water. Brush in and leave to soak in for an hour then hose down and flush away.
