Sauereisen Manhole ChimneySeal F-88 is an elastomeric lining composed of fiber-reinforced, asphalt-modified urethane. ChimneySeal is used as a chemical-resistant membrane or gasket seal for the prevention of water infiltration.

Manhole ChimneySeal has excellent adhesion to most substrates. As a high solids elastomer, it is recommended when movement from temperature change or other causes will be encountered.

Manhole ChimneySeal maintains excellent elasticity and adhesion over a temperature range of -30°F to 250°F. The flexible barrier resists freeze/thaw stresses and movement. When subjected to mechanical stress, the lining has nearly 100% recovery. Manhole ChimneySeal also resists alkalies, salts and acid.


  • Outstanding chemical resistance to acids and alkalies.
  • Remains flexible from -30°F to 250°F.
  • Easy to apply by hand.
  • Urethane-based elastomer.
  • Suitable for application on steel, brick or concrete substrates.
  • Excellent elasticity.


Temperature of Working Area
Maintain an optimum temperature of 60°- 85°F on air, substrate and material during mixing, application, and cure. Store material in the range of 65°- 80°F for at least 48 hours before use.

Surface Preparation
Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.

Brick - The working substrate must be dry and firm enough to withstand imposed loads during normal operation.
Mechanical methods should be utilized to remove old paints, coatings, and deteriorated mortar or brick.

Abrasive blast or high-pressure water blast brick to obtain a uniform, sound substrate. All prepared surfaces must be allowed to dry prior to the Manhole ChimneySeal application.

Concrete - The working substrate must be dry and have the necessary strength to withstand imposed loads during normal operation. For applications where Manhole ChimneySeal is recommended. All voids should be filled with Sauereisen Underlayment F-120 or Filler Compound 209. The choice of underlayment will depend on the severity of the voids to be filled.

Abrasive blast or high-pressure water blast concrete to remove laitance and to obtain a uniform surface texture exposing fine aggregate resembling coarse sandpaper.

Regardless of preparation method used, all surfaces must be free of any loose deposits or contamination.

Metal - Abrasive blast or mechanically abrade the metal surface to a nominal 2.5mil profile employing a SSPC-SP 6 Commercial finish. All protrusions should be ground smooth to eliminate sharp edges.


Packaging consists of premeasured, unitized containers of Hardener Part A and Resin Part B. Completely empty contents of Hardener Part A into Resin Part B. Using a slow-speed ½-inch drill motor affixed with a "Jiffy" type blade, mix for 5 minutes. Thorough mixing of this material is very important.

Mix only complete batches. Material which has begun to set must be discarded. Do not add any adulterants to either component or mixed material.

Manhole ChimneySeal is self-priming and applied at various thicknesses depending upon specification design parameters. Manhole ChimneySeal is easily applied by gloved hand (neoprene or rubber). The most practical method of applying the product within small diameter structures is to wipe the material on with a gloved hand or trowel.


Curing of the ChimneySeal lining is by chemical reaction. While Manhole ChimneySeal has an approximate working time of 45 minutes, initial set occurs in about one hour at 70°F. Manhole ChimneySeal cures to a semi-soft, elastomeric state. Protect the installation site from water or chemicals prior to cure for 48 hours.


For specific applications, a holiday detector can be utilized to ensure a continuous, pinhole-free lining. Pinhole testing should occur after 24 hours at 70°F using a Tinker & Rasor Holiday Detector or similar model. Voltage will be dependent on coating thickness. Consult a Sauereisen representative for details.


Following is typical coverage of F-88:

1-Gallon Unit
12.8 ft2 at 1/8-inch (125 mils) thick

Actual coverage may vary depending on jobsite conditions and surface irregularities.


All equipment should be cleaned with a general orange solvent or mineral spirits within one (1) hour after use and after each day's use. If removal is required after cure, consult Sauereisen for recommendations.


1-Gallon Unit
Hardener Part A-.65 lbs in a pint container
Resin Part B - 7.5 lbs in a 2-gal. pail


Sauereisen Manhole ChimneySeal has a shelf life of one (1) year when stored in unopened, tightly sealed containers in a dry location at 70°F. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.
