About this file
This is a product data sheet for Tnemec Company, Inc.'s Enviro-Crete Series 156 coating, specified for use in the City of Pembroke Pines' exterior stripping and coating project of a 2.5-million-gallon pre-stressed concrete water storage tank. Series 156 is a modified waterborne acrylate flexible, breathable coating designed for concrete and masonry substrates, capable of filling and bridging minor hairline cracks while providing elastomeric protection against driving rain, freeze-thaw cycles, and UV light. The product meets stringent environmental standards including LEED v4.1 Low-Emitting Materials, Collaborative for High Performance Schools-Paints & Coatings, Living Building Challenge Materials Petal 10, and WELL Building Standard v2 X06 VOC Restrictions, as well as Massachusetts' Energy Code air barrier requirements. The mandatory pre-bid meeting was scheduled for April 14, 2025, at 10:00 am, with questions due by April 25, 2025, and bid submission deadline of May 6, 2025, at 2:00 pm. The project timeline is 180 calendar days with an estimated start date of June 10, 2025.
Series 156 is available in matte finish in colors referenced in the Tnemec Color Guide and is supplied in 5-gallon pails and 1-gallon cans. The coating has a volume solids content of 50.9 ± 2.0%, volatile organic compounds of 0.41 lbs/gallon unthinned, and a recommended dry film thickness of 4.0 to 8.0 mils per coat with theoretical coverage of 816 square feet per gallon at 25 microns. Application can be accomplished through airless spray, roller, or brush methods on properly prepared surfaces at temperatures between 40°F and 100°F, with curing time to recoat of approximately 1¼ hours at 75°F and 50% relative humidity. The product carries a 24-month shelf life when stored between 35°F and 110°F and requires surface preparation including cleaning, drying, and removal of contaminants, with primers such as Series 151-1051 recommended for certain substrates. The contractor must comply with all application specifications, surface preparation requirements, and provide comprehensive insurance coverage with the City of Pembroke Pines named as additional insured, along with payment and performance bonds for 100% of the contract price if exceeding $200,000.

Published technical data and instructions are subject to change without notice. The online catalog at www.tnemec.com should be referenced for the most current technical data and instructions or you may contact your Tnemec representative for current technical data and instructions.
SURFACE PREPARATION
STEEL Refer to primer product data sheets for surface preparation recommendations.
GALVANIZED STEEL & NON-
FERROUS METAL
Surface preparation recommendations will vary depending on substrate and exposure conditions. Contact your Tnemec representative or Tnemec Technical Services.
CRACKS Fill hairline cracks less than 1/64 inch (.4 mm) wide by brushing Series 156 into them prior to applying Series 156 over the entire area to be coated. For cracks wider than 1/64 inch (.4 mm) and/or moving cracks, gaps and expansion joints use Series 152 Tneme-Tape. Refer to Series 152 product data sheet for details. Note: Use Series 156 to embed Tneme- Tape prior to topcoating with 156.
PAINTED SURFACES Remove chalk and old paint not tightly bonded to the surface. Apply test patch to check adhesion.
ALL SURFACES Must be clean, dry and free of oil, grease, form release agents and other contaminants. Allow new concrete, plaster, stucco and masonry to cure 14 days. Level protrusions and mortar spatter. Bare cementitious surfaces can be slightly dampened with clean water if product is drying too rapidly during application. Series 151 may improve adhesion on smooth surfaces. Reference SSPC-SP13/NACE 6.

APPLICATION
COVERAGE RATES Dry Mils (Microns) Wet Mils (Microns) Sq Ft/Gal (m²/Gal)
Suggested 6.0 (150) 12.0 (305) 136 (12.6)
Minimum 4.0 (100) 8.0 (205) 204 (18.9)
Maximum 8.0 (205) 16.0 (405) 102 (9.5)
Allow for application losses and surface irregularities. Roller or brush application may require multiple coats to obtain recommended film thickness. Important: Protection against weather, driving rain and alternate freezing and thawing is obtained when coating is applied to form a continuous, void-free film. The coating must be brushed, rolled or sprayed and backrolled onto block. Grooves in scored and fluted block must be brushed. Two coats are normally recommended for lightweight or haydite block. Split-face and split-fluted block must be filled. Contact your Tnemec representative for specific coating system recommendations. Film thickness is rounded to the nearest 0.5 mil or 5 microns. Film thicknesses are calculated from the sq ft/gal figures. There is no method for accurately measuring the film thicknesses of this coating applied over a rough masonry substrate. Application of coating below minimum or above maximum recommended dry film thicknesses may adversely affect coating performance. †
MIXING Stir contents to a uniform consistency.
THINNING Not recommended except when priming highly porous surfaces. Thin first coat 30% or 1 1/4 quarts (1.1L) per gallon with potable water.
APPLICATION EQUIPMENT Airless Spray
Pump Tip Orifice Atomizing Pressure Mat’l Hose ID Manifold Filter
Graco 35:1 Senator or larger
0.019”-0.029” (480-735 microns)
2500-3000 psi (172-207 bar)
3/8” (9.5 mm)
30 mesh (600 microns)
Use appropriate tip/atomizing pressure for equipment, applicator technique and weather conditions.
Roller: Use a 3/8” to 1-1/2” (9.5 mm to 38 mm) synthetic woven nap roller cover. Use longer nap for rough or porous surfaces. Multiple coats may be required to achieve recommended film thickness, depending on applicator technique and roller nap size.
Brush: Use a good quality nylon or synthetic bristle brush.
SURFACE TEMPERATURE Minimum 40°F (4°C) Maximum 100°F (38°C) The surface should be dry and at least 5°F (3°C) above the dew point.
CLEANUP Clean equipment immediately after use; brushes and rollers with hot, soapy water; spray equipment as follows:
1. Pump out excess material from equipment and lines.
2. Pump 10 gallons (40L) of clean water through airless pump or conventional pressure tank and lines.
3. Release pressure from pump or pressure tank and clean all parts and surfaces.
4. Reassemble and flush with clean water. Finish with a final flush of ethyl or isopropyl alcohol.
CAUTION Dry overspray can be wiped or washed from most surfaces. Satisfactory dry-fall performance depends upon height of work, weather conditions, equipment adjustment and proper thinning. Test for each application as follows: Spray from 15 to 25 feet towards paint container. The material then should readily wipe off. Note: Heat can fuse-dry overspray to surfaces. Always clean dry overspray from hot surfaces before fusing occurs. Be aware that exterior surface temperatures can be higher than air temperature. Also, Series 156 has a tendency to show lap marks when spray applied to large, flat surfaces during hot weather. To minimize lap marks stay away from direct sunlight, pre-wet masonry substrates by misting with clean water and lightly backroll with 3/8” nap rollers immediately behind spray application.
