ELASTA-TUFF 5000 is a single component, liquid applied, high adhesion, moisture cured polyurethane waterproofing coating. It is used as the First Coat or Base Coat for most of the polyurethane deck and roof coating systems supplied by TUFFLEX POLYMERS. ELASTA-TUFF 5000 is used in those areas where a low VOC, medium solvent containing base coat is desired.


Basic Uses: ELASTA-TUFF 5000 is the standard Base Membrane used in most of the ELASTA-TUFF Vehicular Traffic Bearing and Pedestrian Deck Coating systems. Please refer to the pertinent Installation Specification Data Sheet on each of these systems.


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. A polyethylene sheet should be used as a blanketing material prior to re-sealing the lid on a partially used container. Prior to the application of ELASTA-TUFF 5000, proper surface preparation procedures must be followed. Refer to the TUFFLEX Technical Bulletin on Surface Preparation of Plywood and Concrete Substrates.


ELASTA-TUFF 5000 cures faster when applied during warm weather and high humidity conditions and slower during cool temperatures and low humidity conditions. The rate of cure may be accelerated by incorporating Tufflex Accelerators.


Shelf Life: Nine (9) months after manufacture when continuously stored in unopened metal pails at temperatures under 80ºF. Stir thoroughly prior to use.


Standard Color:  Concrete Gray


Surface Preparation:  All substrates must be free of all contaminants and should be primed with TUFFLEX water-based or TUFFLEX solvent-based epoxy primers prior to the application of ELASTA-TUFF 5000. Apply primers at a rate of 250-350 square feet per gallon depending upon substrate porosity or surface profile.


Application: ELASTA-TUFF 5000 is normallyapplied at a rate of 40 to 50 square feet per gallon, per coat; resulting in a 32 to 40 mil wet film thickness. When applying onto sloped or uneven surfaces, two or more coats of the standard ELASTA-TUFF 5000 Base Coat are required for this coverage.   Allow a minimum of 16 to 24 hours cure time between coats. ELASTA-TUFF 5000 is easily applied by squeegee, roller or notched trowel. Always follow by backrolling. Application should not commence unless the ambient temperature is 45°F or higher, and should not proceed during inclement weather. ELASTA-TUFF 5000 is usually used in conjunction with ELASTA-TUFF 6000-AL Aliphatic Top Coats. Tufflex Accelerators may be added to ELASTA-TUFF 5000 to compensate for slower cure time in cold weather or for a shortened cure time for rehabilitation or repair projects. Please refer to the Accelerator Technical Bulletins or contact TUFFLEX for details.
