Create a long lasting, stylish finish when using Natural GftK vdw 850 Patio Pointing Mortar. This hard-wearing sweep in patio jointing compound is ideal for use with natural stone and porcelain paving. GftK vdw 850 Natural is easy to install and once in place is resistant to frost and abrasions. Before buying, we recommend that all customers read our Product Guide.
Prior to grouting the installation should be dry and the open grout joints clean, dry and free of residues. Porous or textured tiles/slabs may require sealing before grouting with a suitable impregnating sealer. If in doubt trial an inconspicuous area to check for staining and correct colour before commencing. Wet the Paving. Absolutely soak the area to be jointed with water using a hose. The paving must be saturated before starting and remain soaked throughout the application process - in fact, the wetter the better. Do not shortcut this process, particularly if working with absorbent or sensitive materials such as Sawn Sandstone, Granite and many Limestone types. Particularly sensitive stone will need sealing, preferably before laying.
Mixing
Mixing the joint mortar: Pre-mix the aggregate, then add the binder and mix with the drill and spherical paddle mixers for approx. 3 minutes until smooth and homogeneous. Do not mixpartial quantities of the product. No water should be added to the mix.
Application Process
Filling the joints: Apply immediately after mixing by pouring directly onto the pre-wetted surface. Work the mortarthoroughly into the joints using a hard rubber squeegee, whilst spraying lightly with water from a hose. The surface should be kept constantly wet during application. We recommend working from the highest to the lowest points. Brushing off and cleaning: Remove any excess mortar residue immediately from the area by spraying lightly with water from a hose. Be careful to clean the paved surface towards areas not yet jointed. Remove any final residual mortar with a damp coconut fibre brush. Do not brush this residual mortar into any unfilled joints. It is importantto make sure that no water or residual mortar remains on the surface. Refer to the product guide for further information.

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.
