Sauereisen ConoCrete - Model No. 115 - Chemical & Food Grade Epoxy Floor System
ConoCrete - Chemical & Food Grade No. 115 is a chemically-resistant, 100% solids, aggregate-filled, epoxy floor system. It is ideal for resurfacing old and protecting new concrete floors from chemical and physical abuse. The physical properties of these materials far exceed those of concrete, providing a surface that not only has greater durability, but a chemical-resistant barrier to the substrate. ConoCrete may be used in all kinds of manufacturing, processing, storage, and shipping areas. It is specifically formulated to resist food acids, fats and oils. This skid-resistant system handles thermal shock in refrigeration areas and is resistant to harsh cleaning solutions.
- Excellent resistance to food acids and by-products.
- Conforms to USDA regulations for use in federally inspected meat & poultry plants.
- Easily cleaned nonskid surface.
- Available Colors: 53 gray, 63 tile red.
- VOC compliant.
Temperature of Working AreaFor optimum conditions, maintain a temperature of 60°-85°F on air, substrate, and material components during mixing, application, and cure.
The monolithic components should be maintained at 65°F to 80°F for 48 hours prior to beginning work.
At temperatures below 65°F, the application becomes more difficult and curing is retarded. Above 80°F, the material working time decreases.
Application in direct sunlight and rising surface temperature may result in blistering of the materials due to expansion of entrapped air or moisture in the substrate. In rising temperatures it may be necessary to postpone the application or apply during cooler hours.
Concrete - Refer to SSPC-SP13/NACE 6 'Surface Preparation of Concrete' for detailed guidelines.
New Concrete - All structures must have the necessary strength to withstand imposed loads during normal use and operation. Surface must be floated free of ridges or depressions and all voids filled with Sauereisen Underlayment No. F-120 or No. 209 Filler Compound. The choice of underlayment will depend on the severity of the voids to be filled. Surfaces should be sloped a maximum 1/4 inch per foot for drainage.
Surfaces must be 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
exposing fine aggregate resembling coarse sandpaper.
Old Concrete - Concrete must be dry, firm and must have the necessary strength to withstand imposed loads during normal use and operation.
Mechanical methods should be utilized to remove laitance, old paints, protective coatings, and attacked or deteriorated concrete.
Abrasive blast, high-pressure water blast, or acid etch concrete to obtain uniform sound substrate.
All structural cracks should be repaired. All slopes should be reestablished with Sauereisen Underlayment No. F-120.
All prepared surfaces must be allowed to dry prior to monolithic application. Regardless of preparation method used all surfaces must be vacuumed to remove any loose deposits or contamination.
ConoWeld Primer No. 501 is the standard primer used under normal conditions. However, for the hard to penetrate surface, PenePrime No. 500, a water-based epoxy primer, is recommended.
Primer - Primers are packaged in premeasured containers consisting of Hardener Part A and Resin Part B which must be mixed together before use. Remix the Part A and Part B before combining.
Completely empty contents of Hardener Part A into Resin Part B container. Using a slow-speed ½-inch drill motor with a 'Jiffy' type blade, mix thoroughly for 3 minutes until blended to uniform color. Primer is ready for use immediately after mixing.
ConoCrete - Packaging consists of premeasured, unitized containers of Hardener Part A, Resin Part B, Aggregate Part C, and Pigment Part D. Remix Part A and B before combining.
Regular unit - Regular units are packaged in two 20-ft2 batches.
Completely empty contents of Pigment Part D and Resin Part B into a clean mixing container. Using a slow speed ½- inch drill motor affixed with a 'Jiffy' type blade, mix thoroughly until blended to a uniform color.
Add Hardener Part A to Resin/Pigment blend and mix for 2 minutes. Slowly add 2/3 of Aggregate Part C and mix until all material is wetted out. Then add remaining Aggregate and continue mixing until uniform in consistency.
Large unit - Completely empty contents of Pigment Part D into Resin Part B container. Using a slow speed ½-inch drill motor with a 'Jiffy' type blade, mix thoroughly until blended to a uniform color.
Completely add Hardener Part A to Resin/Pigment blend and mix for 2 minutes. After mixing, add total contents into a 4-7ft3 mortar mixer and add three bags of Aggregate Part C. Mix for 3 minutes before adding fourth bag of Aggregate. Continue mixing until all material is wetted out and uniform in consistency.
Mix only complete batches. Material which has begun to set must be discarded. Do not add any solvent, additive, or
adulterant to the ConoCrete.
Primer - Apply primer to the concrete using a squeegee, short nap adhesive roller with a nondetatchable core, or nylon
bristle brush. Prior to the application of ConoCrete, inspect the primed surface for voids, bubbles, or defects that may result in blistering or pinholes in the topcoat. Repair with Sauereisen No. 209 Fast Set if necessary.
Primer cure times vary by product. ConoCrete can be placed immediately after application of ConoWeld No. 501, but must occur within 6 hours. while the primer is wet to tacky. If recoat time exceeds six hours, consult Sauereisen.
When PenePrime No. 500 is specified, the curing window prior to placement of ConoCrete is 3 to 24 hours.
ConoCrete - Material should be placed immediately after mixing. Do not let mixed material remain in mixing vessel. Spread ConoCrete with a spreader box, screed, or by hand to desired thickness (1/4 inch minimum). Use a steel trowel to compact and finish the surface. Finishing must be completed within 30 minutes from mixing. Consult Sauereisen for power trowel directions.

*Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and specific project conditions.
Do not allow water or chemicals on the ConoCrete surface for a minimum of 24 hours. For harsh chemical or physical environments cure a minimum of 72 hours prior to exposure.
ConoCrete systems do not require a topcoat. For specific service conditions, a topcoat may be desirable. Contact Sauereisen for a recommendation and appropriate ConoGlaze topcoat for your application.
