Sandstone Patio Pack Laying Guide

This guide is to help landscapers lay our traditional patio and project packs of Indian sandstone paving. It covers roughly one crate of paving, which is a nominal coverage of 18.9 square metres.

Included in your crate:

900 x 600mm, 16 pieces
600 x 290mm, 16 pieces
600 x 600mm, 16 pieces
290 x 290mm, 12 pieces

Sandstone patio pack laying pattern

Lay a suitable sub-base material, such as a crushed hardcore, well compacted onto the subgrade. This is followed by a 30 to 50mm laying course of concrete made up of 6 parts sharp sand and 1 part cement.
ALL NATURAL STONE MUST BE LAID ON A FULL BED OF CONCRETE THAT SUPPORTS THE WHOLE FLAGSTONE.
Before laying the flagstone, the application of a priming slurry such as UltraScape Primer to the underside will improve adhesion.
Carefully lay the flagstone and tap it into place with a rubber mallet to the correct level. Place the next flag with an adequate joint and continue with the appropriate laying pattern.
Ensure the top is the widest surface with natural stone flags.

Laying paving slabs onto the mortar bed

Lay full flagstones first and complete the cuts at the end. After a few days, the joints can be pointed with a mortar made up of 4 parts washed sharp sand to 1 part cement. Alternatively, joints can be filled using a proprietary jointing compound. All stone paving flagstones are designed to be laid with joints.
All cement stains from the mortar must be washed off immediately, or the flagstones will be permanently stained. The use of acids to clean off mortar or other stains is not recommended, as it can have a detrimental effect on the product.
When laying circles, start from the centre stone and work outwards. If contained within a patio, lay the circle first.
On very light coloured flagstones, consideration should be given to using a white cement together with a bonding agent in the mortar, as this minimises absorption of the darker cement onto the flagstone.
