CHEMPRUF 2211 linings are highly chemical resistant fabric reinforced lining systems.
CHEMPRUF 2211 is designed for primary or secondary containment applications for tanks, trenches, containment dikes, absorbers, scrubbers and floors. The CHEMPRUF 2211 may be used as a lining or as a membrane in conjunction with chemically resistant brick sheathing. When used as a membrane, the lining can be used at higher process temperatures.

FAQs about Chempruf 2211
Q: What is the chemical resistance of the Chempruf 2211 systems?
A: CHEMPRUF 2211 Lining Systems are resistant to a broad range of strong acids, such as 98% sulfuric acid, nitric acid to 40%, chromic acid to 20%, alkalies, as well as many organic solvents, such as butyl acetate, ethyl alcohol, toluene, xylene, and 1,1,1-trichloroethane. Refer to the CHEMPRUF 2000 SERIES Chemical Resistance Chart, 4-2000, for specific information.
- Chempruf 2211 C offers excellent chemical resistance to environments exposed to hydrofluoric acid, fluoboric acid, fluosilicic acid, and sodium hydroxide.
- Chempruf 2211 AO is preferred for service conditions with abrasive slurries, high-velocity air containing particulate matter or environments exposed to fluorides, fluoride salts, and sodium hydroxide.

*Depending on service conditions, ATLAS may recommend the use of an optional finisher.
Q: What surface preparation is required?
A: The substrate must be structurally sound, clean, dry and free of all contaminants, such as sealers, curing compounds, coatings, oil, dirt, dust, and water. Previously applied coatings or paint must be removed.
Concrete: The prepared concrete substrate shall have a minimum tensile strength of 250 psi.
(1.72 MPa). Concrete surface must be sufficiently cured and comply with moisture testing as prescribed by ACI Test Method 515 R-16 “Dryness of Surface”. Concrete surfaces should be grit blasted to a finish similar to the profile of 100 to 120 grit sandpaper Cracks in the concrete substrate 1/16″ (1.6 mm.) wide or greater must be opened to a minimum 1/4″ (6.4 cm.) cleaned, primed and filled with Chempruf 2211.
Carbon Steel: Metal surfaces should be grit blasted to an SSPC-SP5 or NACE #1 white metal blast cleaned surface finish. Profile height must be 3 (0.076 mm.) to 4 mils (0.102 mm.).
Q: What is the best temperature range for the application of Atlas Chempruf 2211 systems?
A: Store all materials referred to in this Data Sheet at 70°F (21°C) to 80°F (27°C) for 24 hours prior to use. The minimum temperature for installation is 65°F (18°C). Do not apply when the relative humidity is greater than 75% or the substrate temperature is less than 5oF (3oC) above the dew point.
Q: How do I apply Atlas Chempruf 2211?
A: Application Instructions
1. Apply Chempruf E Primer with a brush or roller.
2. Trowel apply a 1/16″ (1.6 mm.) WFT basecoat. Imbed the Chempruf Fabric and roll into the wet basecoat. Apply Chempruf 2211 saturant with a medium nap roller. Allow the saturant coat to harden.
3. Trowel apply a 1/16″ (1.6 mm.) WFT topcoat. Smooth with a short nap roller lightly wetted with Chempruf E Smoothing Liquid. Allow hardening.
4. If ATLAS recommends the use of an optional finisher, apply Chempruf 211 or Chempruf 121 with a short nap roller. Depending on service conditions, two coats may be required.
Protect uncured primer, the basecoat, saturant, topcoat, and finisher coat(s) from moisture contamination until minimum cure time is attained.
Q: How do I clean my tools and equipment?
A: Steel wool, soap, and warm water will remove the materials referred to in this Data Sheet from mixing tools and equipment if cleaning is done immediately after use. Solvents, such as methyl ethyl ketone, toluene or xylene, will have to be used after the material has begun to harden. Fully hardened material will have to be removed by mechanical means. Dispose of residues and wastes in accordance with the directions in the Safety Data Sheets and government regulations.
Q: Are there technical service representatives available?
A: ATLAS maintains a staff of Technical Service Representatives who are available to assist you with the use of ATLAS products.
