Paving Flag Laying Guide Getting Ready
• Avoid rubbing and damage to Flags by carefully stacking them on timber battens with spacers between them.
• Select paving from different packs throughout the job, to blend colour shades. Laying
• Make up a slightly wet mortar mix of 1 part cement to 5 parts building sand.
• A PVA, SBR or equivalent bonding agent can be added to the mortar to assist bonding, particularly with natural stones. Alternatively coat the back of each flag with neat wet cement and bonding additive just before laying.
• You may also consider using an appropriate plasticiser additive in the mix.
• Prepare a full bed of mortar ahead of each Flag, approximately 25mm thick, but allowing for the variation in thickness between Flags.
• Tap the Flag down to the required level, using a rubber mallet.
• If the Flag will not level with several gentle taps, lift it, adjust the level of the mortar bed and relay the Flag.
• Keep checking levels and gradient across a number of slabs. Stringlines can be helpful to define levels and lines within the laying pattern.
• Maintain the correct joint width by gently shuffling with a trowel. Small pieces of timber are useful as temporary spacers.
• If you need to cut Flags, a power tool with a suitable diamond tipped cutting disc will cut accurately through our products. After Laying
• Do not walk on the paving for at least 24 hours.
• During wet or frosty weather, cover the paving for protection until mortar has cured.
• Then point as soon as possible.
