Fabick Joint Seal physical properties, applications, tools, specifications

Product Description:

Fabick Joint Seal (FJS) is a two component 100% solid polyurea based joint sealant.  FJS is a self-leveling joint sealant designed to protect interior horizontal concrete expansion and control joints from spralling, chipping, and breakdown.  This elastomer displays fast cure times and excellent adhesion to concrete.  FJS can be applied at temperatures ranging 20° F to 180° F.  This polyurea elastomer displays excellent chemical resistance, water insensitivity, and thermal stability at high and low temperatures.  FJS may also be used under traditional floor coatings (such as epoxies, polyureas and polyurethanes) or tiles to smooth the joints and provide protection from cracking and sinking caused by non-elastomeric joints sealants.

Primary Applications:

FJS was designed to protect against the abuse to concrete joints caused by heavy load transfers from such items as forklifts, steel-wheeled carts and trash dumpsters.  Some typical uses include:         

• Concrete Control/ Expansion Joints
• Concrete Spall Repairs
• Cold Storage Facilities
• Merchandise Distribution Centers
• Home Improvement Stores
• Bridge Headers
• Warehouse Floors
• D.O.T. Road Sensor
• D.O.T. Pothole Road Repair
• U.S.D.A and F.D.A Acceptable

 Application Equipment:

This material may be applied using a plural component pump (2:1 or 1:1 by Volume), or by plural component cartridges.  This proportioning unit must e capable of supplying the correct pressure and heat for the required hose length on a consistent basis.  This characteristic is mandatory to apply this elastomer in a consistent, efficient manner.  When hand mixing, care must be taken to mix and pour quickly as the FJS is designed to gel quickly.  For small jobs, the JS cartridge may be utilized.

Available Colors:

• Black
• Custom tinting on request

Installation Recommendations:

FJS adheres well to sound concrete substrates.  All surfaces should be free of moisture, loose particles and debris.  Any moisture present in the joint should be eliminated prior to installation.  Using a diamond blade saw, saw the joint vertically to 90° angles to a minimum depth of 1 inch.  The joint should be widened slightly to ensure adhesion to freshly opened concrete.  Care should be taken not to adversely affect adhesion by “burnishing” the sides of the joint with a grinder.  After sawing or grinding, care should be taken that minimal amounts of dust and debris are left over in the joint.  The joint should be vacuumed using a common “shop-vac” to remove as much dust and debris as possible or high-pressure air depending on the site location.  FJS should be placed in the joint full depth, overfilled, and allowed to cure for a minimum of ten minutes before shaving level with the concrete.

Spalls/Blowouts:

Remove all existing material from the spall or blowout.  Any moisture present in the spall should be eliminated prior to installation.  Using a diamond blade saw saw the joint vertically to 90° angles to a minimum depth of 1 inch.  The spall should be widened slightly to ensure adhesion to freshly opened

concrete.  Care should be taken not to adversely affect adhesion by “burnishing” the sides of the joint with a grinder.  After sawing or grinding, care should be taken that minimal amounts of dust and debris are left over in the spall.
Fill the spall/blowout with dry rock filler (i.e. dry pea gravel if required) to one inch of the surface.  Fill the remaining void to surface level with the FJS.

Application Notes:

It is very important to maintain constant pressures while installing JS with a plural component pump.   A variation in pressures can result in loss of properties, poor color retention and bubbling.  Hose heat is not required at ambient temperatures. Low temperatures may require the use of hose heat to improve flow ability.

Repairs and Maintenance:

Repairs to divots caused by unforeseeable abuse can be repaired very easily.  The damaged area should be removed to sound FJS and concrete.  It may be necessary to remove FJS with a pocketknife or pneumatic saw and should include removal of all damaged materials to the fresh concrete.  The damaged are should be squared to 90° and solvent wiped with acetone.  FJS should be placed in the damaged area

Clean-Up Disposal:

Cured product may be disposed of with out restriction.  The uncured isocyanate and resin portions should be mixed together and disposed of in a normal manner.  “Drip-free” containers should be disposed of in accordance with local, state and federal laws.

Safety and Handling:

Refer to MSDS Sheets

Shelf Life and Storage:

Six months in factory delivered unopened drums.  Keep away from extreme heat, cold and moisture.  Maintain at a proper storage temperature of 60 ° F-80 °F.  The components used in the JS have been specially formulated to with stand low temperature applications.  The material can be stored at temperatures as low as 10 °F with no gelation of the components.  However, it is recommended to warm the material to a minimum of 60 ° F before application.

Packaging:

FJS is available in 5 Gal buckets or 55 Gal drums.  The “A” side contains 500 lbs. of material.  The “B: Side contains 450 lbs. Of material.

Shipping Information:

FJS can ship via commercial truck lines.

Limitations:

FJS is an aromatic polyurea.  While the physical properties may not be affected, the elastomer could yellow and chalk with exposure to UV or Hg vapor light.  It is highly recommended to use a dark color for any applications requiring color stability.  If color stability is mandatory, contact the manufacturer for recommendations.  The chemical resistance chart should be consulted prior to any application. FJS was designed to protect the edges of concrete control and expansion joints.  FJS will pull away from the joint edges if too much slab movement is encountered.  This characteristic allows for early replacement and to alert the property owners that movement is present.

Warranty:

The technical data and any other printed information furnished by Fabick Inc. is true and accurate to the best of our knowledge.  FJS conforms to in-house quality control procedures and should be considered free of defects.  Due to the wide range of applications of this product, it is impossible to assume responsibility for any errors in regard to application, coverage, workmanship, over-spray or injuries resulting from the use of FJS.  Fabick, Inc. makes no warranty, expressed or implied, or it products and shall not be liable for indirect or consequential damage in any event.

Additional Results:

In certain cases, it may be recommended by the manufacturer to utilize a different formulation speed or hardness depending upon the specific needs of the application.  The FJS series offers several different hardness readings from 45 (Shore A) to 75 (Shore D).  The physical properties, gel times and reaction times vary with the formulation.  The FJS formulations are available in 2:1 and 1:1 volume rations.  Call the manufacturer for specific technical information.
