Installation
London Stone recommend that all our materials are installed by experienced professionals. The following is a summary of installation.
Install Preparation
All substrates must be suitably dry and comply with the recommendations in the British Standards and TTA Guidance documents. All substrates should be clean and thoroughly sound they should be free from standing water, oils, grease, dust, loose particles.
The adhesive should be added to clean water and mixed with a suitable slow speed drill and paddle until a lump free mortar is produced. The water ratio can be adjusted depending on the application. For non-slip application on walls, mix 20 kg with approx. 5 L water. For full wettability and bedding on floors, mix 20 kg with up to 6 L water. The amount of water to be added, is an approximate guide. It is possible to obtain mixtures of variable consistency depend on the application. The mixed adhesive is usable for up to 2 hours depending on site temperature and conditions. Do not attempt to remix adhesive or add extra water after it has begun to stiffen as this will cause a loss in performance.
Application Process
The mixed adhesive should be applied to dry areas on walls using a suitable notched trowel and applied by solid bed on wet areas on walls, on all exterior tiling and on all floor tiling. It is recommended that trowelling is carried out in straight lines rather than ‘swirls’. In addition, when fitting very large format tiles, it is highly recommended to also fully skim the back of the tile with a thin layer of adhesive. Tiles should be placed with a firm twisting action before the adhesive has skinned over, i.e. within the open time of up to 30 min. Regularly check to ensure adequate contact between adhesive, tile and substrate. ‘Dot and Dab’ method of fixing is never acceptable.
Cleaning Tools
Wash all tools frequently to avoid material bonding to them.
Cleaning During Application
Always keep a clean sponge and water available for wiping off any excess or spillages from paving.

Installation Ancillaries Calculator
Use our handy, in-page, calculator to find out how much pointing product you require to install your paving.
The calculator automatically updates with the required amount based on the quantity of paving you have inserted in the spec-chart.
Simply tick the ‘add to order’ boxes and then the ‘add to basket’ button to purchase.
Please note, the calculator provides accurate figures based on our recommended installation method. On-site variables can lead to more/less material being used.
If you would like a different colour grout with your paving, we recommend adding the recommended quantity to basket from the pointing product page, as the in-page calculator only allows you to add our recommended colour to basket.
