Application & Use:

SURFACE PREPARTION: Substrate must be structurally sound, free from grease, oil, paint, dirt, dust, sealers, laitance, curing compounds, and any other foreign material which may prevent proper bonding.

When applying to cementitious surface, that surface must be fully cured. Water should be able to penetrate the substrate. If water beads, surface contaminates are present. Insure that surface is not subjected to hydrostatic pressure, if so, do not apply. Concrete slabs and mortar beds should have a coarse finish to assist in bonding.

When applying Lightweight Cement the substrate must have a minimum of 2,000 psi compressive strength. Must be dry and properly cured. Do not apply in areas that are going to be wet.

MIXING: STANDARD SET MORTAR is to be field mixed with potable water and mechanically mixed to desired consistency based upon scope of application. Add approximately 6-1/2 quarts of water into mixing container. Slowly pour the contents of the bag into the mixing water. Mix until a firm, workable consistency is achieved. If more water is needed, add small amounts and continue to mix until consistency is achieved. Let the mixture slake or stand 5 to 10 minutes, then stir again and use. Stir occasionally but do not add more water. Desired consistency should be trowel ridges that stand without slumping. Do not exceed a total volume of 1.5 gallons of water for each 65-lb bags.

APPLICATION / PLACEMENT: Be sure mixed material is consistent from batch to batch. Apply STANDARD SET MORTER to substrate with flat trowel. Use a properly sized notch trowel to insure proper coverage and spread of material under tiles. Work placed STANDARD SET MORTAR with notched trowel to create rows of adhesive to proper thickness for item being placed. Press tile firmly in place, moving back and forth to insure a proper set. Adjust tile quickly and then gently tap into place with rubber mallet or beating block until flush with other units. Periodically pull up a tile or stone and check the back to insure proper adhesive coverage. If mortar has already taken its set under the lifted tile, remove mortar and replace with fresh STANDARD SET MORTAR. Placed STANDARD SET MORTAR can be a total of 3/8” thick once item has been set and tamped into place.

CURING: Curing time will vary due to weather conditions, thickness, substrate absorption, etc. Material should be protected from weather elements and foot traffic for a minimum of 24 hours.

EXPANSION JOINTS: Provision for movement (expansion joints and control joints) and other changes of plane in all installations are required. Do not bridge expansion or control joints.
