What is the best way to lay Indian sandstone?
How to lay sandstone paving
- Select an area that’s firm, level and well drained.
- Remove 125mm (plus the depth of the paving) of top soil/vegetation.
- Create adequate falls for drainage.
- Install edge restraints, these should be sufficiently robust.
- Lay a minimum of 100mm sub base.
Which way up does Indian stone go?
It matters that natural paving is laid the right way up
(Remember, in this example the wider surface is lying on the sub base, therefore even if the slabs are touching underneath, this has the effect of splaying the joint at the top surface).
Does Indian sandstone need sealing before laying?
The short answer: No. The long answer: Natural stone has survived for 1000’s of years without any chemical treatments, so it’s unlikely to fall to pieces without a layer of sealant that some suppliers insist it needs. But there are benefits of doing so.
Can you lay Indian sandstone on a dry mix?
There is much discussion on this subject but the short answer has to be no. Laying sandstone paving should only be done with a full wet bed of Mortar at a ratio of 5.1 sand and cement and the slabs should be primed individually before laying using a slurry primer to aid with adhesion and to prevent salt blooms.
How long will Indian sandstone last?
Indian sandstone paving can have a very long lifespan if installed and maintained properly. With a cheap installer and poor care you can expect 2 – 10 years from your paving. With a solid base and repointing every few years you can in theory get 30 – 50 years from your paving or perhaps more.
Do you need to slurry Indian stone?
It is important that ALL granite paving must have a cement and SBR liquid slurry mix painted on the entire back on the slab before fixing. If you do not do this, it may result in the slabs drying out at different rates and causing patchiness or effect the surface of the slabs.
Can you lay block paving upside down?
If you get them laid upside down the arises will break off next harsh winter so that you’ll end up with chamfered corners anyway. As much as you might be surprised these things are usually like it for a reason.
Which way do you lay a sandstone slab?
Laying your Indian paving slabs
(You only need a sponge and clean water to do this.) Then, prime the underside of each slab with a dedicated priming product, or fine mortar slurry. This is where we should say – make sure that you’re laying your slabs the right-side up!
What do you mix with pointing Indian sandstone?
An average ratio of sand to cement is 5 parts sand to 1 part cement – you can go stronger than this but not weaker. We recommend only mixing one wheelbarrow or bucket full at a time as it will harden if left for too long.
What is the best mix for laying slabs?
Paving slabs are bedded in a mortar mix with four parts sharp sand to one part cement. Measure your quantities using a shovel or a bucket – for example, four buckets of sand for every one bucket of cement.
