XL-70C¨ BRIDGE•COTE¨, is a heavy-bodied, heavy-duty, fine textured coating formulated with interlocking pigments and aggregates dispersed in a high polymeric based organic resin system. XL-70C¨ BRIDGE•COTE¨, is specifically formulated to function both as a concrete coating and a concrete curing compound for use over concrete substrates that require curing.
For the protection and beautification of bridges, above-grade exterior surfaces such as concrete walls, columns, spandrels, median dividers, curbs, retaining walls, etc. Available in spray and roll on formulation. XL-70C¨ BRIDGE•COTE¨ reduces the cost of rubbing, grouting and sacking of concrete. Helps minimize surface irregularities and will not internally support fungus or mildew. Specifically formulated for bridge-systems, factory mixed and ready-to-use.

DRYING/CURING TIMES
To touch: 48 hours
Final cure: 2-3 weeks, minimum
Note: These times based on ideal weather.CLEAN UP/CONTAINERS/SHELF LIFE
- For wet material clean up with mineral spirits. For dry use MEK ( Methyl Ethyl Ketone).
- 5 gallon containers, 30 and 55 gallon drums.
- 12 months shelf life based on following: containers shall be stored upright and air tight in temperature above 40¡F not exceeding 100¡F, in dry place. AVOID FREEZING. Any skins formed on surface material must be removed prior to moving containers or mixing.
II. SURFACE PREPARATION
Surface preparation prior to the application of an applied finish coating shall consist of general surface finish in accordance with the specific requirements of the highway department. In order to fill air pockets, honeycomb, etc., surface shall be supplemented, if necessary, either by the use of grout composed of one part portland cement, two parts screened and washed sand, graded to pass the 16 mesh sieve, and sufficient water to produce a thick liquid mix, or other suitable masonry patch material. The grout shall be applied using burlap pads, float sponges or other acceptable methods. As soon as grout has taken its initial set, the surface shall be brushed to remove all loose grout, leaving surface smooth and free of any air holes. Surface to be coated shall be free from efflorescence, flaking coatings, oil, release agents and other deleterious substances prior to the application of the applied finish coating.
Release agent must be removed and may require light sandblast or waterblast.
