To lay bluestone stepping stones, the slurry or wet mix method is a recommended approach. This method ensures a strong and durable bond between the bluestone pavers and the base. Here is a step-by-step guide on how to lay bluestone stepping stones using the slurry or wet mix method:
1. Prepare the base: Start by preparing a crushed rock base with a thickness of 100mm. Ensure the base is compacted and levelled properly. This will provide a stable foundation for the bluestone pavers.
2. Create the slurry or wet mix: In a mixing container, combine 4 parts sand with 1 part cement. Mix the dry ingredients thoroughly. Then, add 1 litre of bonding agent to the mixture and continue mixing until it forms a slurry or wet mix. The bonding agent enhances the adhesive properties of the mix, ensuring a strong bond between the pavers and the base.
3. Spread the mixture: Using a trowel, spread the slurry or wet mix evenly onto the prepared crushed rock base. Make sure to cover the entire area where the bluestone stepping stones will be laid. The thickness of the slurry or wet mix should be around 20-30mm.
4. Butter the back of the bluestone pavers: Before laying the bluestone pavers into the slurry or wet mix, it is highly recommended to butter the back of each paver with adhesive. This can be done by applying a thin layer of adhesive onto the back surface of the paver using a trowel or a notched trowel. Buttering the pavers helps to create a stronger bond and prevents them from shifting or becoming loose over time.
5. Lay the bluestone pavers: Carefully place each bluestone paver onto the wet mix, starting from one corner and working your way across. Ensure the pavers are aligned properly and leave a small gap (around 5mm) between each paver for jointing. Use a rubber mallet to gently tap the pavers into place and ensure they are levelled.
6. Jointing: Once all the bluestone pavers are laid, allow the slurry or wet mix to set for a while. Then, fill the gaps between the pavers with a jointing material, such as fine sand or a proprietary jointing compound. This will provide stability and prevent weed growth between the pavers.
7. Finishing touches: After the jointing material has been applied, sweep off any excess material and ensure the joints are filled evenly. Clean the bluestone pavers with water and a brush to remove any residue or adhesive marks.
By following these steps, you can successfully lay bluestone stepping stones using the slurry or wet mix method. This method provides a strong bond and ensures the longevity of your bluestone pathway or patio. Just remember to take your time during the installation process, pay attention to detail, and enjoy the process of creating a beautiful and functional outdoor space.
