THE CONCRETE PROTECTIVE COATING SYSTEM ONE COAT APPLICATION • HIGH BUILD • SINGLE COMPONENT
G Street Bridge - Richmond, IN 1991 • Restoration Award
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. TEX•COTE¨ XL-70¨ BRIDGE•COTE¨ reduces the cost of rubbing, grouting and sacking of concrete. Helps minimize surface irregularities and will not internally support fungus or mildew. Specially formulated for bridge-systems, factory mixed and ready-to-use.
The application of this sand-like textured finish through the use of spray or rollers provides a highly protective coating against salt scaling, spalling and chloride ion intrusion of the concrete surfaces. It also eliminates countless man hours of conventional concrete rubbing.
That is why for over 18 years bridge engineers in the know have trusted their structures to TEX•COTE¨ XL-70¨ Bridge•Cote.

To Touch: 48 hours
Final Cure: 2-3 weeks, minimum
Note: These times based on ideal weather
- For wet material clean up with mineral spirits. For dry use MEK (Methyl Ethyl Ketone).
- 5 gallon (18.9 Liters) containers, 30 (113.5 Liters) and 55 (208 Liters) gallon drums.
- 12 months shelf life based on following: containers shall be stored in upright and air tight in temperature above 45¡F (7.2¡C) not exceeding 100¡F (37.8¡C) in dry place, avoid freezing. Any skins formed on surface of material must be removed prior to moving containers or mixing.
SURFACE PREPARATION
Surface preparation prior to the application of an applied finish coating shall consist of a general surface finish in accordance with the specific requirements of the highway department. In order to fill air pockets, honey comb, 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 efflorescense, flaking coatings, oil, release agents and other deleterious substances prior to the application of the applied coating. Release agent must be removed and may require light sandblast or waterblast.
XL-70¨ BRIDGE•COTE¨ APPLICATION RATES
XL-70¨ BRIDGE•COTE¨ may be applied over damp, uncured or cured masonry surfaces which have been properly prepared and are clean and free of efflorescense, incompatible release agents, and curing compounds.
Spray/Roll On: Manufactured to meet Federal Specification TT-C-555B and the listed performance tests. A one coat application at 50 S.F. per gallon develops a minimum 15 mil dry film thickness.
The approved coverage rate for TEX•COTE¨ XL-70¨ BRIDGE•COTE¨ may vary in different states and regions. Please consult the governing highway department or government agency for their requirements.
Limitations:
- Do not thin XL-70¨, do not use as grout.
- Do not mix XL-70¨ in drum with other type of paint.
- Agitate XL-70¨ thoroughly prior to use.
- May be applied over a damp, but not wet with liquid water surface.
- Application temperature is above 40¡F (7.2¡C) and rising, not exceeding 100¡F (37.8¡C).
- Do not apply if rain is imminent or over frozen surface.
- Backside of retaining walls shall be waterproofed with asphalt type, below grade sealer.
