Slurry Bond Coats

Polymer or Latex Fortified Slurry Bond Coats for Traditional Mortar Beds

LATICRETE latex slurry bond coats are used to bond ‘wet’ consistency toppings or leveling beds over horizontal substrates, such as concrete or masonry. Their purpose is to provide an adhesive layer that bonds the substrate and the material going over it.

For tile setting purposes, traditional installation methods required dusting dry cement, or spreading a cement paste/slurry over the semi-dry mortar bed just prior to placing the tiles. The tiles are then placed in the cement rich surface, or more correctly, a Portland cement/water paste and “beaten” to fully embed them in the mortar bed.

Instead of the traditional cement paste, 254 Platinum, 335 Premium Flexible Adhesive or 211 Crete Filler Powder gauged with 4237 Latex Additive, mixed to a soft, wet slurry consistency is applied with a flat side of a trowel over the bed. The tiles are placed in the wet slurry and “beat-in” with a rubber mallet and beating block.

A slurry bond coat is also used to bond a mortar bed to a concrete, masonry or other suitable surface, including a previously applied hardened mortar bed. The slurry bond coat is applied to the substrate immediately prior to installing the fresh mortar bed.

LATICRETE slurry bond coats provide much longer “open” or working time for mortar bed installation, particularly in hot climates. It also has stronger bond to ceramic or stone tile, ensuring improved resistance to vibration, traffic and physical shock.
