Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data is subject to reasonable deviation.

Sauereisen RestoKrete® Filler - Compound No. 209 is an epoxy formulation specifically designed to fill voids, irregularities, and air pockets in concrete and steel. The filler compound provides a smooth surface for the application of epoxy monolithics. No. 209 is not compatible with vinyl ester topcoats. The No. 209FS is a faster setting formulation.

CHARACTERISTICS

  • Fills and seals irregularities in concrete, steel and brick substrates.
  • Suitable for application over damp or dry concrete surfaces.
  • Easy to apply.
  • Quick set time.

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.

Metal - Abrasive blast to a nominal 2.5-mil profile employing SSPC-SP5 White Metal Blast for immersion and SSPCSP10 for other service conditions. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges.

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 re-grouted with No. 209. All active hydrostatic leaks must be stopped with Sauereisen InstaPlug™ No. F-180 prior to No. 209 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

Mixing
Remix Hardener (Part A) by shaking the container. Remix contents of the Liquid component (Part B) for a minimum of 2 minutes with a slow speed paddle or "Jiffy" mixer. Combine contents of Hardener to Liquid and mix for a minimum
of 3 minutes. Add Powder (Part C) 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.

Installation
To maximize working time, spread mixed RestoKrete™No. 209 onto a plasterer's hawk upon completion of the mixing. Apply No. 209 to concrete with a smooth plasterer's rubber float or steel trowel. After application, excess material must be removed by using the edge of the float, trowel, or a squeegee.

COVERAGE

RestoKrete®No. 209 Regular Unit
680 ft2 per unit at 1-mil thick

No. 209 Large Unit
3,876 ft2per unit at 1-mil thick

No. 209FS
136 ft2 per unit at 1-mil thick

Sauereisen RestoKrete® No. 209 may be used as a skim coat to provide a uniform surface over new concrete. In these applications, the number of surface voids to be filled in the concrete will vary. For estimating purposes, a small unit of No. 209 will cover approximately 45ft2 when used as a skim coat. No. 209L will cover approximately 250ft2 when used as a skim coat.

Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and project specifics.

SETTING/CURING

Filler Compound No. 209
Sauereisen RestoKrete® No. 209 has a working time of approximately twenty minutes. The material takes an initial set in roughly three hours at 65°F. This minimum cure time of three hours should elapse prior to topcoating.

Please consult Sauereisen's Technical Service Department prior to any recoat applications exceeding 72 hours.
Generally, No. 209 may be recoated with a SewerGard® system up to 3 days later when the surface temperature is maintained at 65°F or below. In all cases, the surface must be free from any contaminants including amine blush.

Filler Compound No. 209FS
No. 209 FS (Fast Set) has a working time of approximately five minutes at 70°F.The material takes an initial set in one hour. No. 209FS can be topcoated with a SewerGard® system after one hour.

The maximum duration for topcoating RestoKrete™ No. 209FS should not exceed 36 hours when the surface is
maintained at 70°F. For temperatures below 70°F, working time and set time are lengthened. Please consult Sauereisen's Technical Service Department prior to any recoat application exceeding 24 hours.

CLEAN-UP

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