LSE 7000 APPLICATION GUIDELINES
Surface Preparation

Follow ACI standards for surface preparation.

Remove all grease, oils, waxes, release agents and any other impedance to adhestion. Concrete substrates shall be structurally sound and free of standing water. A rough surface profile will maximize adhesion. Saw cut the perimeter of the repair to a maximum of 1/2 inch deep. Saturate the surface with water and remove standing water.

Mixing

LSE 7000 requires only water for mixing. Use 6-1/2 to 7 pints per 50 pound container.

Place water in the mix vessel first and add the dry ingredients while mixing. Mix for 3 to 5 minutes until all lumps are dispersed and the mix is consistent. Use a mud paddle with a drill or a LSE Pail Mixer. A mortar mixer may be used for larger batches.

Wash equipment periodically with water to prevent material build up.

Do not "temper' the material with additional water and do not add admixtures.

For repairs greater than 2 inches in depth, add clean 3/8 inch pea gravel up to 30 pounds per 50 pound batch.

Placement

Place the material as soon as it is mixed. Working time is 15 minutes (less in hot weather). Push firmly into the void and assure that all the void surface is in contact with the fresh material. Trowel smooth and texture as needed.

* In hot and windy conditions, soak the repair area with water or use an approved bonding agent. The repair area should be covered with wet burlap or coated with a latex curing compound.

Limitations

Do not temper after initial mixing. Do not add other cements or additives.

Health and Safety

Read and follow all MSDS instructions for the LSE 7000 and for all other materials used concurrently at the job site. CAUTION: Contains cementitious materials; wear rubber gloves and appropriate dust mask-avoid breathing dust. Avoid contact With skin and eyes--irritation and burns may occur. If contacted in eyes, flush with clean potable water and seek medical attention. Wash skin thoroughly with soap and water after handling.
