One 30 lb. bag covers approximately 40 - 50 square feet with a 1/2" by 1/2" notched trowel, and 70 - 80 square feet with a 1/4” by 3/8” notched trowel.

Flexelite conforms to ANSI A118.1, ANSI A118.4, and ANSI A108.5.

Surfaces to receive Flexelite must be clean and dry. Coatings, sealers, curing agents, and loose material must be removed prior to installation. All substrates must be secure and stable.

Add Flexelite to water and mix to a thick trowelable consistency. Mix at low speed to avoid entraining excess air into the material. Let the material slake for 10 minutes and remix prior to use. Do not add additional water to retemper material.

Scratch in a small amount of material onto substrate to insure proper bond, then apply additional material with a suitable trowel. It is important when adhering marble and granite that 100% coverage is obtained. When installing irregularly sized marble and granite units, backbuttering each piece and setting, using a large notched trowel is recommended. This will maximize bonding area and improve the evenness of the finished surface. Set the tile in the material with enough force to insure 100% contact and twist tile slightly. Ten minutes after the tile is set, do not adjust, move, or put pressure on the tile. Only spread enough material that can be covered with tile within 15 minutes. Remove unhardened mortar with water. Once mixed, mortar can be used for up to 4 hours.

For applications over cement backerboard, adhere backerboard according to backerboard manufacturers recommendation using Flexelite applied to the plywood substrate.

For applications over existing ceramic tile, plastic laminate, vinyl flooring (non-asbestos), or VCT residue, roughen surface with coarse sandpaper or other abrasive. Clean to remove loose material.
