RestoKrete®Hi-Build Filler Compound - No. 209HB is an epoxy material specifically designed to refinish large surfaces and open joints within concrete. No. 209HB provides a smooth finish and appropriate bonding surface for epoxy topcoats. RestoKrete® Hi-Build Filler Compound is formulated to minimize sagging which permits thick application of the product where necessary. Do not use with vinyl ester topcoats.

CHARACTERISTICS

  • Seals gaps and other irregularities in concrete and brick substrates.
  • Suitable for filling voids larger than typical concrete bugholes.
  • Easy to apply.

AREA PREPARATION

Temperature of Working Area
Maintain a temperature of 60°-90°F on air, substrate, Hardener, Liquid and Powder components during mixing, application, and cure. The material components should be maintained at 65°F to 85°F for 48 hours prior to use.

At temperatures below 60°F, the application becomes more difficult and curing is retarded. Above 85°F, the material working time decreases. It is recommended that the material components be stored in a cooler area prior to mixing.
Shading the substrate and using ice water to cool mixing equipment is not uncommon. In extreme temperatures it may be necessary to postpone the application or apply during cooler hours.

Surface Preparation
Concrete - Refer to SSPC-SP13/NACE 6 "Surface Preparation of concrete" for detailed guidelines.

New Concrete - Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and obtain uniform surface texture.

Old Concrete - Surfaces should be made free of oil, grease, water and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast or high-pressure water blast to remove all foreign particles and attacked or unsound concrete and obtain uniform sound substrate. Concrete must be firm and structurally sound as specified by the architect/engineer.

Brick - Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. This can be
achieved by chemical cleaning. Abrasive blast or high-pressure water blast all foreign particles and attacked or unsound mortar from the joints. Loose brickwork should be regrouted with No. 209HB. All active hydrostatic leaks must be stopped with Sauereisen InstaPlug™ No. F-180 prior to RestoKrete® No. 209HB 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.

APPLICATION

Priming
Primer is not required with the use of No. 209HB. However, when necessary, an epoxy primer may be used in conjunction with No. 209HB to minimize out-gassing in the concrete substrate. Consult Sauereisen's Technical Service
Department for recommendations for this type of application/requirement.

Filler Compound Mixing
Remix contents of Liquid component for a minimum of 2 minutes with a slow-speed paddle or "Jiffy" mixer. Remix
Hardener by shaking. Combine contents of Hardener to Liquid and mix for a minimum of 3 minutes. Gradually add Powder and continue mixing until thoroughly blended. Mix only complete batches.

Material which has begun to set must be discarded. Do not try to retemper the material.

Filler Compound Installation
Spread the RestoKrete® Hi-Build Filler Compound onto a plasterer's hawk after mixing. This will maximize working time. Apply RestoKrete™ No. 209HB to concrete with a smooth plasterer's rubber float. After application, excess material must be removed by using the edge of the float or a squeegee. Another method of applying No. 209HB is to utilize a pump and portable injection equipment. Consult Sauereisen for details.

COVERAGE

The theoretical coverage is 5,000 ft2 per unit at 1-mil thick. At the thickness of 1/8 inch (125 mils) the approximate coverage will be 40 ft2 per unit. Since the actual required thickness will vary, estimates must be calculated as needed.
Coverage is theoretical and will be affected by surface conditions, porosity, application techniques and project specifics.

SETTING/CURING

RestoKrete® Filler Compound No. 209HB has a working time of 30 minutes at 70°F. The material takes an initial set in a matter of hours. No. 209HB Filler Compound can be topcoated after 4 - 6 hours at 70°F.

No. 209HB has a maximum recoat window of 72 hours at 70°F. Consult Sauereisen's Technical Service Department for recommendations when the recoat window will exceed 72 hours. In all cases, the surface of the No. 209HB must be clean and free of all contaminants, including amine blush, prior to recoating.

For temperatures below 70°F, working time and set time are retarded. For temperatures above 70°F the working time and set time are accelerated.

PACKAGING

The three components of RestoKrete™ No. 209HB are packaged as a 19.89-pound unit.

No. 209HB Unit - 19.89 pound unit

CLEAN-UP

All equipment should be cleaned with MEK before material cures. If removal is required after cure consult Sauereisen for specific recommendation.
