Before any tile, stone or membrane
can be installed, the surface must be clean and free of any grease, wax, oil,
dust, dirt and any other material that can act as a bond breaker. The best
tile, stone or membrane installation is only as good as its adhesion to the
substrate. Therefore, it is very important that the substrate is being
carefully cleaned and prepared to assure maximum bonding and finishing
tolerances.
Concrete sealers or curing compounds
should not be applied to the surface of concrete slabs that are to receive
finished flooring, and if the concrete surface has a sealer or curing compound
present, it must be removed. Also note that a concrete slab with a very smooth
shiny surface, due to over-troweling, should be mechanically scarified to ensure
that the mortar or membrane can achieve a suitable bond to the concrete. Prior
to the application of the installation system, the concrete surfaces should be
thoroughly cleaned to remove any loose particles of plaster, soil, preparation
residuals and other foreign material.
Whether the concrete surface is new
or old, the subsurface tolerance should be met for thin-set, thick bed (mortar
bed) ceramic and stone tile installation. For more information read Technical Data Sheet TDS-1118.
