Product Description

Colorcoat AL-Ester is a single component, liquid applied, moisture-cured, aliphatic polyester-polyurethane surface protection coating.

General Information

Basic Uses: 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”, TUFFLEX “SOFT” 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.

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.

Colors and Packaging: Six (6) STANDARD COLORS: Pacific Gray, Sidewalk Gray, Rocky Gray, Monterey Sand, Ash Brown and Desert Tan. Custom colors and non-stocking colors are available with minimum ordering quantities. Contact our Order Desk for further information.

Available in 5 gallon and 55 gallon containers.

Product 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.

Mixing Instructions:  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.

Application: Colorcoat AL-Ester is normally applied at a rate of 80-100 square feet per gallon, per coat, resulting in afilm thickness of 16 to 20 wet mils. Coverage will vary dependingon 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 AL-Ester to allow for light traffic on decks within a matter of hours. Please refer to the Technical Bulletins on Accelerators or contact TUFFLEX for details.


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.
