The tiles are offered in specific thickness intervals such as 8 mm, 10 mm, 8-17 mm etc. See full overview in the product tab. The intervals indicate the variation in thickness between individual shale slabs within the specified grading. Although each individual tile is generally uniform in thickness, small irregularities may occur.
To attach the slate directly to the substrate, the use of slate glue/mortar glue is recommended. The height of the substrate need not be significant to compensate for the variation in thickness of the tiles. Minor irregularities are easily corrected by applying the right amount of glue.
If slate tiles are to be laid outdoors, foundation work is essential. Consideration must be given to efficient and good drainage of moisture to avoid uneven moisture exposure from the underside. This is particularly important to prevent spots or shields on the surface.
It is recommended to follow the manufacturer’s recommendations for the correct installation of slate when using glue. The various glue manufacturers provide detailed descriptions that ensure a safe and efficient installation.
