What type of product is UNIQUE FLEXICRETE® XP Polymer-Modified Mortar?

This concrete patching material is an easy-to-use, polymer-modified mortar. It is a non-shrink, volume-stable, and trowel-grade mortar.

Use it to repair roadways, curbs, shallow utility cuts, pre-cast, sidewalks, parking garages, industrial floors, and loading docks.

This concrete mortar repair mix can be used from featheredge to two inches deep.

Do not use UNIQUE FLEXICRETE® XP on unsound concrete surfaces. It is not intended for applications over 2 feet deep. For deeper applications, use UNIQUE FLEXICRETE® 25 Polymer-Modified Concrete Mix.

For overlay applications, at least one section should be prepared to evaluate the suitability of the materials and procedures.

Damp cure all UNIQUE FLEXICRETE® XP mortar repair installations. The objective of damp curing shall be to maintain the continuously wet surface until the product has achieved sufficient strength. Begin curing as soon as the surface has lost its moist sheen. Keep exposed surfaces wet for a minimum of one hour. When experiencing extended setting times due to cold temperature or the use of retarder, you may need longer cure times.

All you need to do is add UNIQUE FLEXICRETE® XP polymer modified mortar to the pre-measured water.

UNIQUE FLEXICRETE® XP can be opened to foot traffic in 4–6 hours and vehicle traffic in 8–12 hours.

You can extend the cure time by using cold or ice-cold water. Speed up the set time by using warm or hot water.

No, UNIQUE® concrete patching products are water soluble prior to drying. Clean your container and tools with water before the material dries.

Fifty pounds of UNIQUE FLEXICRETE® XP yields approximately 0.54 cubic feet of finished product when mixed with 4.4 quarts of potable water.
