SAI SANDSTONE Prepare the concrete base. The concrete area should be firm, solid, reliable and have no cracks, it should also be a flat surface. If not flat, by screening on top of concrete you will produce a flat surface. Foundation requirement Gap: you can leave between 3mm to 10mm joint depending on the design you want to achieve Glue: Tile adhesive and Cement base can be used. Check the glue manufacture for the suitability for sandstone. Grout: Tile grout can be used, it is recommend that use of light colours of grout be applied to get less change, otherwise it can make sandstone look dirty or stained. To use between joints instead of grout 1 part cement Expansion Joint: b) Put an expansion joint where a paving area length or width is more than 6 meters long this will also assist with any movement that may occur. Sealing: Depending on the area you are sealing they sometimes require different sealers for their protection, please check the sealing information sheet for relevant details.
