We have put together a step by step guide to help you make the right decisions and to guide your planning to ensure that you get the results that you are looking for.
This guide can be used for all paving slabs including sandstone, crazy paving and granite paving. The details below are not an exhaustive list of the do’s and don’ts in laying paving but they are a good start.
We recommend that whenever laying Natural Stone you should mix your paving from 3-4 different packs/crates (where possible). Proper stone selection will allow the colours to blend and help to improve any shade variations that may occur between packs, giving your patio a more natural look.
It is recommended to use a slightly wet mortar mix – 1 part cement: 5 parts building sand. Some paving slabs can vary in thickness and as such the following five spot method is recommended.
- Starting from a corner or straight edge, trowel five large dabs of mortar at each corner and in the middle of each slab’s intended position, placed slightly higher than the finished level of paving.
- Once you have laid the first slab, lay the 5 spots of mortar for the next slab. You could also lay a strip of mortar where the next joint will be, this will help minimise pointing afterward. A paving joint of minimum 10-15mm is recommended.
- Use a rubber mallet to tap each slab down to the required level. Check all levels and falls during the laying process using a spirit level.
- Do Not Walk on the paving for at least 24 hours. A fall on the patio is vitally important as this will prevent water from lodging on the patio.
If you need to cut a lot of slabs it is advisable to hire a powered cutting tool with a diamond tipped blade. Any hire shop will advise you of the relevant machine and blade you will need. Take relevant safety precautions and ask your hire shop for the tool instructions and relevant safety equipment.
There are a variety of tools and methods available to assist with the pointing process for paving stones. ROMPOX jointing mortar is highly recommended. One of the most popular methods is to mix sharp sand and cement (3:1). As soon as possible, except in cases of impending bad weather, all of the joints should be rounded.
Cleaning and Maintenance
We recommend you clean your paving at least every 6 months. Avoid using power washers as it will lift the jointing. We do recommend the use of sealants as they are suited to the extremes of weather we experience in Ireland.
