ConoCrete - Fast Patch No. 149 is a three-component, fast setting epoxy monolithic that is designed for patching cracks and holes. This material is ideal for use on highways, bridge decks, docks, ramps, traffic aisles, industrial floors and airport runways. Fast Patch No. 149 produces extremely high strengths and takes an initial cure in just two hours.

CHARACTERISTICS

  • Skid-resistant profile for safety.
  • Two hour set minimizes downtime.
  • Gray color.

AREA PREPARATION

Temperature of Working Area
For optimum conditions, maintain a temperature of 60°-85°F on air, substrate, Hardener, Resin and Aggregate 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.

Surface Preparation
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. 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 obtain uniform sound substrate.

All prepared surfaces must be allowed to thoroughly dry prior to Fast Patch application. Regardless of preparation method used, all surfaces must be vacuumed to remove any loose deposits or contaminants.

Transition Detail "Key"
All exposed perimeter edges, including doorways, drains, traffic aisle sides, etc., must be saw cut to a minimum depth of 1/2 inch then chipped out at a 45° angle on the inside of the area to be resurfaced with ConoCrete - Fast Patch. All saw cutting and keying should be done prior to final surface preparation. Contact Sauereisen if more detail is required.

APPLICATION

Mixing
Packaging consists of premeasured unitized containers of Hardener Part A, Resin Part B, and Aggregate Part C. Remove containers of Hardener Part A and Resin Part B from the five gallon pail. Remix Part A and B before combining.

Do not remove Aggregate Part C, using the five-gallon pail as the mixing container. Completely empty contents of Resin Part B into the five-gallon pail. Using a slow-speed ½-inch drill motor affixed with a "Jiffy" type blade, mix thoroughly until blended to uniform color.

Add Hardener Part A to Resin/Aggregate blend and mix for two minutes until 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 any component or mixed material.

Installation
Material must be placed immediately after mixing. Do not let mixed material remain in mixing vessel. Use tamper and steel trowel to compact and finish surface. Finishing must be completed within 10 minutes from mixing.

COVERAGE

No. 149 unit 4 ft2 per unit at 1" thick or approximately .33 ft3.
*Coverage is theoretical and will vary depending upon surface conditions, porosity, application techniques and specific project conditions.

SETTING/CURING

Do not allow water, chemicals, or traffic on the material surface for a minimum of 2 hours at 70°F.

TOPCOAT

ConoCrete - Fast Patch No. 149 does not require a topcoat; for specific service conditions, a topcoat may be desirable.
Contact Sauereisen for a recommendation on your application.

PACKAGING

Regular unit: 40 pounds shipping weight.
One five gallon pail containing:

Part A Hardener 1 quart can
Part B Resin 1/2 gallon can
Part C Aggregate Loose aggregate within pail

*Containers are filled by weight, not volume. Container size does not indicate volume of contents.

CLEAN-UP

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

SHELF LIFE

ConoCrete - Fast Patch No. 149 has a shelf life of one year when stored in unopened, tightly sealed containers in a dry location at 70°F. Avoid freezing. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.
