Sauereisen RestoKrete® Epoxy Modifed Cement 208 is a substrate repair material and water resistant barrier for prevention of inflow and infiltration in concrete or brick substrates.
RestoKrete™ 208 is an epoxy-based mortar specified for substrate repair where structural integrity needs to be restored. RestoKrete® 208 is designed to fill voids, irregularities, and air pockets in concrete.
- Pumpable and sprayable through straight shot nozzle
- Can be applied by spincast spray nozzle
- Moisture tolerant
- Designed to be top-coated with most Sauereisen systems including ConoFlex 381
Temperature of Working Area
For optimum conditions, the substrate should be maintained at 60°F to 85°F for 48 hours prior to beginning work.
RestoKrete™ 208 may be applied at temperatures below 60°F; however, curing is slowed.
Above 85°F, the material working time decreases. It is recommended that the material components be stored in a cooler area prior to mixing.
Surfaces should be made free of oil, grease, water, and other contaminants that may inhibit bond. Concrete must be firm and structurally sound as specified by the architect/engineer.
Hydroblasting should be utilized to remove laitance, contaminants, or loose particles and to produce a clean, sound surface. All standing surface water should be removed prior to applying RestoKrete™ 208.
Mixing should be done mechanically with a slow-speed mortar mixer or drill motor with a "Jiffy" type mixing blade to obtain a uniform consistency. The mixing equipment must be clean and free of contaminants.
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 2-3 minutes. Add Powder (Part C) and continue mixing for 2-3 minutes or until thoroughly blended. Mix only complete batches.
*For a stiffer mix consistency, up to 15% of Part C Powder may be added to the mix. See "PACKAGING" section on page 2 for quantities to be added.
Material which has begun to set must be discarded. Do not try to retemper the material.
By Trowel Method
Sauereisen RestoKrete® 208 can be applied by trowel at a thickness up to ½ inch.
To maximize working time, spread mixed 208 onto a plasterer's hawk upon completion of the mixing. Apply 208 to concrete with a smooth plasterer's rubber float or steel trowel. After application, excess material may be removed by using the edge of the float or trowel.
Sauereisen 208 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 regular unit of 208 will cover approximately 49 ft2 @ 1/16 inch thickness. 208 large unit will cover approximately 99 ft2 @ 1/16 inch thickness when used as a skim coat.
Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and project specifics.
By Spray Method
When using a mobile rotor-stator pump, apply a uniform coat at a thickness of 1/16 to 1/4 inch. The following equipment is typical for rotary-sprayed applications of substrate resurfacing materials:
Rotor/Stator Pump outfitted with an appropriate spincaster nozzle or a straight-shot nozzle for rotary spray applications.
Moisture Separator for collecting condensation within air lines.
Material Hose of 1" to 1-1/4 inch diameter and 15-feet length with internal expanded male ends and cam locks, with capacity of 300 psi required.
Air Hose of ½-inch diameter and 50-feet length from compressor to wet spray nozzle. Specify 200 psi and 2 lug Chicago fittings.
Air Hose of 1-inch diameter and 15-feet length from Moisture Separator to Spinning Nozzle Assembly. Specify 200 psi capacity with one end Chicago fitting and one end brass female swivel.
Cam-Lock Couplings of 1-inch and ¾-inch diameter (2 sets each).
• 3/16 to 1/4 inch spray tips
• Tip retainer nut
• Pole gun assembly
Other Outside Source Equipment
• 180 cfm Air Compressor
• 5500 watt Generator with 220-volt single phase
If Sauereisen RestoKrete® 208 is applied by trowel or spray, finishing after material placement is optional. A broom or brush finish is not required.
Proper curing of 208 is critical to the serviceability of the completed structure. 208 may be top coated after its initial set in 5 hours at 70°F. Final set is achieved at 48 hours at 70°F.
All equipment should be cleaned by scrubbing with a stiff brush and water at the end of each working period or when build-up becomes pronounced. A mild abrasive should be recirculated through the pump and hoses.
When mixed at the proper ratio of powder, liquid and hardener, a unit of 208 will yield the following:
449.5 in3 per unit
24.96 ft2 per bag @ 1/8-inch thickness
12.48 ft2 per bag @ ¼-inch thickness
6.24 ft2 per bag @ ½-inch thickness
898.59 in3 per unit.
49.92 ft2 per bag @ 1/8 inch thickness
24.96 ft2 per bag @ 1/4 inch thickness
12.48 ft2 per bag @ 1/2 inch thickness
