COLORCOAT AL-ESTER is the abrasion-resistance and weather resistant Top Coat used in most of the TUFFLEX Vehicular Traffic Bearing and Pedestrian Deck Coating Systems. Please refer to the pertinent Installation Specification Data Sheet on each of these systems. COLORCOAT AL-ESTER is used where optimum weather resistance, abrasion resistance and color stability are required. It is used in conjunction with TUFFLEX “TUFF” and TUFFLEX STANDARD OUTDOORS ELASTOMERIC Membranes. The cured top coat easily withstands the extreme environmental conditions encountered in exterior construction environments. When used in conjunction with elastomeric base membranes, the COLORCOAT AL-ESTER composite system contracts with lower temperatures and readily expands when temperatures increase. COLORCOAT AL-ESTER may also be used alone as an abrasion-resisting industrial maintenance coating.
- Mixing Instruction
Mix COLORCOAT AL-ESTER thoroughly before using or before adding the optional TUFFLEX CURE ACCELERATORS. Material should be mixed thoroughly with a mechanical mixer (Jiffy Mixer) at low RPM. Care must be taken not to whip air into the mixture as this may cause pin-holes.
- Installation
Surface Preparation: All surfaces to be coated with COLORCOAT AL-ESTER must be thoroughly dry and free of all contaminants, including oxidation on old top coats or base coats as well as construction debris or deposits.
Application: COLORCOAT AL-ESTER is normally applied at a rate of 80-100 square feet per gallon, per coat, resulting in a film thickness of 16 to 20 wet mils. Coverage will vary depending on the aggregate size, texture or degree of surface porosity. The larger the aggregate used, the lower will be the coverage rate due to the greater surface area being covered. COLORCOAT AL-ESTER is easily applied by squeegee, roller, or notched trowel. Always follow by backrolling. At 50% relative humidity and 77°F, the coating will be dry to the touch within 16 hours. Traffic should not be allowed on the finished coating until firm (usually 24- 36 hours). TUFFLEX Accelerators may be added to COLORCOAT ALESTER to allow for light traffic on decks within a matter of hours.
- Maintenance
If a COLORCOAT AL-ESTER coated surface is damaged, it can be repaired by light sanding or by scrubbing with industrial soap and water, followed by a thorough rinse with water. Follow this with a solvent wipe with acetone or xylene and TUFFLEX 7113 penetrating cleaner. When the surface is dry, apply additional COLORCOAT AL-ESTER.

Safety & Health
- Precautions
Exposure to urethanes or petroleum solvents may cause allergic skin or respiratory reactions. Do not get into eyes, onto skin, or clothing. This product is for professional use only.
Storage & Handling
- Limitations
Containers that have been opened must be used within one or two days, since the product is a moisture-reactive material that will gel or set up when exposed to moisture in the air. Keep lid tightly sealed when material is not in use.
- Shelf Life
Twelve (12) months after manufacture when continuously stored indoors in unopened metal pails at temperatures under 80°F. Stir thoroughly prior to use.
