Sauereisen H2OPruf No. F-190 is a two-component, crystalline water proofing coating for use on concrete or masonry structures to prevent water seepage through the substrate. 

Application of the waterproofing kit is by masonry brush or mechanical spray equipment. No F-190 withstands both positive and negative side pressure.

This material is specially recommended to withstand hydrostatic pressure on the negative side of below grade structures. Two coats withstand water pressure up to 69 feet of head. Three coats will seal a substrate exposed to 100 feet of water head.

Sauereisen H2OPruf No. F-190 is used to seal sumps, trenches, tanks, manholes and below grade walls in wastewater treatment, power, pulp & paper, and steel industries.


  • Promotes crystalline reaction within the concrete matrix to prevent water seepage through the concrete.
  • Creates a highly durable barrier to water flow and seepage through concrete and masonry surfaces.
  • Inorganic cementitious coating.
  • Cleans up with water.
  • Application by brush or spray.
  • Safe to use - no VOCs.


Temperature of Working Area
Maintain a temperature of 40o-85oF on air, substrate, Powder, Liquid, and water components during mixing, application, and cure. The monolithic components and substrate should be maintained at 40oF to 85oF for 48 hours prior to beginning work. ]

At temperatures below 60oF setting is retarded.

Above 85oF, the material working time decreases. It is recommended that the material components be stored in a cooler area prior to mixing.

Surface Preparation
Concrete or masonry must be firm and structurally sound as specified by the architect/engineer. Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. All structural cracks must be repaired. Abrasive blast or high-pressure water blast concrete to remove laitance and obtain uniform surface texture. Substrate should be saturated and remain damp prior to application.

If chemical cleaning is utilized to remove contaminants, substrate must be neutralized. If abrasive or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner. If surface does not have desired conditions, repeat surface preparation procedure.

Stopping Active Leaks
After surface cleaning, all visible pressure leaks must be sealed using Sauereisen InstaPlug No. F-180, or No. F-370 Hydroactive Polyurethane Grout.

In areas where voids exist, patching should be completed using Sauereisen Underlayment No. F-120. In the areas to be patched, all cracked or disintegrated material shall be removed to expose a sound substrate. Repair materials shall be applied in accordance with manufacturer's instructions.


Mixing should be done mechanically with a slow-speed, paddle-type mortar mixer or a drill motor with a "Jiffy" type blade. Place five quarts of potable water in a clean mixing container. Vigorously shake the 16 ounce container of inorganic copolymer admixture Liquid and add to the mixing water. Mix this solution well. Slowly add the Powder and mix for three minutes to achieve a uniform slurry. When spraying or applying in the presence of higher temperatures, add up to an additional quart of cold water.


Brush application -Using a masonry brush, liberally apply and work the first coat into the surface to a thickness of 1/16 inch (63 mils). After the first coat has taken an initial set, (min. 1.5 hours depending on temperature) the second coat can then be applied at the same thickness.

Spray application -apply a uniform coat to a minimum thickness of 1/8 inch (125 mils). The total thickness is not to be greater than 1/4 inch. Immediately use a masons brush to produce a more uniform finish.

The following equipment is typically used for spray application:

Pump -Quikspray Carousel Pump Model #1020CEM-3 with 1 h.p. variable speed electric motor OR RFI parastaltic pump Model #RS - 45.

Material hose - one inch or 3/4 inch I.D. rated at 6,000 psi minimum.

Gun - follow pump manufacturer's recommendation with a minimum 1/8 inch orifice.

Attachments -affix the material supply hose directly to the pump outlet. No screens, filters or surge tanks shall be used between the pump and nozzle. Moisture traps are recommended.


Proper curing of the materials is critical to the serviceability of the completed structure. Sauereisen H2OPruf No. F-190 has an initial set at 70oF in 8 hours. Final set at 70oF is in 24 hours.


Concrete - first coat is 80 to 100 ft2 at 1/16 inch thickness. Second coat is 100 to 120 ft2.

Concrete block -first coat is 70 to 80 ft2 at 1/16 inch thickness. Second coat is 85 to 100 ft2.

Brick - first coat is 70 to 90 ft2 at 1/16 inch thickness. Second coat is 90 to 110 ft2.

Spray application is 25 to 50 ft2 in one coat.

Quantities do not include losses incurred during application or normal density variations.


Sauereisen H2OPruf No. F-190 has a shelf life of one (1) year, when stored in unopened, tightly sealed containers in a dry location at 70oF. Avoid freezing. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.


Consult Material Safety Data Sheets and container label Caution Statements for hazards in handling these materials.


One kit of H2OPruf No. F-190 weighs approximately 52 pounds and consists of:
Powder - 50 pound bag.
Liquid - One 16-ounce bottle.


All equipment should be cleaned by scrubbing with a stiff brush and water at the end of each working period or when buildup becomes pronounced.
