How to Lay Flagstones
To get started an adequate sub-base is required.
Joint Widths:A 12mm joint width is a fairly standard choice.
Mix: 5-7:1 sharp sand/cement mix is recommended.
Screed Bedding: Suitable for calibrated flagstones. The bedding material needs to be spread across the whole area to be flagged at a depth of 5-10mm thick.
Spot bedding: is NOT recommended as its makes them unstable and susceptible to fracturing, amongst various other reasons.Random Flagstone Pattern
To keep a completely random, rustic looking pattern we suggest abiding by 3 rules:
• Never have 4 corners meeting
• Have no more than 3 joins running parallel
• Do not have joins running for longer than around 3 metres.
Project Packs come in 5 different sizes of flagstones, but the widths are all the same which enables you to use a tram line pattern. Just make sure that you keep alternating the lengths of flagstone used in each tram line to stagger the joints.
Flagstones can be sealed with a suitable sealant, although it is not necessary. The great British climate will weather away any spills or marks on outdoor flagstones, but it may be worth considering sealing indoor flagstones to prevent staining.
