3. PRODUCT DESCRIPTION

Composition
EDGE-PRO XL is a two component, 100% solids, gray epoxy joint filler. When cured XL is semi-rigid (like very hard rubber) and exhibits a hardness of Shore A80 minimum

Basic Use
XL was developed specifically for filling joints in concrete floors defined by ACI and PCA as Class 5 or below. Class 5 is generally described as an industrial floor subject to vehicles with rubber-like wheels and light-to-moderate traffic frequency and loads. XL acts as a supportive transition as traffic travels across joints and protects the joint edges from spalling. Thus the name Spal-Pro, for spall protection.

XL should be used in both contraction and construction joints subject to traffic, in both new and existing floors.

4. LIMITATIONS
XL should not be used in the following:

a. True Expansion Joints
b. Exterior Joints (paving, etc.)
c. Freezer/Cooler Floor Joints
d. Joints subject to chemical exposure

For Class 6-9 Floors, our heavy duty filler, MM-80, is recommended.

5. CORRECT JOINT DESIGN
XL should be installed full joint depth in saw cuts and 2" deep (min.) in thru-slab construction joints (see sheet XL-3). Cracks and voids below may be choked off with silica sand or SPAL-PRO ROD provided by Metzger/McGuire. Limit silica in saw cuts to 1/4" max.
DO NOT USE COMPRESSIBLE BACKER ROD IN SAW!

TECHNICAL INFORMATION

6. ADVANTAGES
EDGE-PRO XL is an excellent economical alternative to our heavy duty MM-80 for joints subject to softer wheels and lighter loads.

EDGE-PRO XL is sufficiently rigid to carry loads over joints and protect edges from spall damage, yet remains slightly resilient to aid in absorbing wheel impact and avoiding brittleness.

EDGE-PRO XL exhibits low range tensile and adhesive strengths, characteristics necessary to allow the joints to open as the concrete shrinkage progresses for 1-2 years.

EDGE-PRO XL is an excellent selection as a joint filler to be used under tile and other floor coverings. It will support the floor covering when under load and will not be adversely affected by the covering adhesive.

EDGE-PRO XL, best of all, is formulated with the high quality components you would expect from Metzger/McGuire, the name known worldwide for optimum floor joint protection.

7. PACKAGING AND COLOR
The standard color of EDGE-PRO XL is concrete gray. Standard packaging is a two gallon kit.
(One gal. part "A", one gal. part "B").

8. APPLICABLE SPECIFICATION
Standardized specifications for semi-rigid industrial floor joint fillers have not been developed. EDGE-PRO XL meets the basic criteria set forth in the following technical publications:

"Guide for Concrete Floor and Slab Construction,"
A.C.I. report 302.1 R-80.

"Concrete Floors on Ground,"
Ralph E. Spears, Portland Cement Assoc.(1983)

9. USDA COMPLIANCE
As of August 1995 the USDA/FSIS will no longer provide blanket approval of the acceptability of any product. To meet the USDA's new guidelines, we certify that EDGE-PRO XL meets the standards for acceptability as defined by the USDA in their applicable regulations. Letter of certification for specific projects can be obtained from Metzger/McGuire upon request.

10. TECHNICAL ASSISTANCE
Complete technical support and literature are available from manufacturer or from authorized distributors.

11. AVAILABILITY
EDGE-PRO XL is immediately available from Metzger/McGuire or from authorized construction distributors.

12. WHERE TO SPECIFY AND FILE
EDGE-PRO XL is exclusively for use in concrete floors and therefore should always be referenced in 03251 (expansion/contraction joints) & cast-in-place concrete, 03300. It is not a sealant and should not be specified as part of 7900, other than for cross reference.

13. INSTALLATION
The following are abbreviated.  Read full installation instructions thoroughly before use.
Storage
Keep XL in a cool, shaded area. Protect from freezing.

When To Install
XL should be installed no earlier than 30 days after concrete is placed. A 60 to 90 day minimum cure is recommended. Our experience has shown that the ideal installation time is when the building or room is under permanent temperature control.

Installation Temperature
Ambient temperature should be 50°F or above. Joints should be free of frost. If frost is suspected, wipe with solvent.

Joint Preparation
Joints should be free of saw-cut laitance, dirt, and debris. A simple method is to use a circular saw with a masonry blade, tilting it at a slight angle to ensure sidewall contact. Remove all residue with vacuum or compressed air. Remove curing and sealing compounds. Under normal circumstances, no primer is required for XL. If unusual conditions are suspected, contact our office.

Do not use any base rod under XL. A maximum of 1/8" - 1/4" of silica sand may be placed in saw cuts at contractors option.

Mixing
Use a variable speed drill at low RPM and a paint mixing paddle (Jiffy or similar) to mix XL. Stir both components separately before combining. Combine A and B and mix at low speed per can instructions. Do not dilute or alter XL. Mix entire kit.

Dispensing
XL has a viscosity similar to a medium motor oil. It can be poured from the can, but best results are obtained by using a metal, closed-barrel caulk gun or a power, dual-feed dispensing machine. The use of a gun or dispensing machine will ensure a neater application and full depth penetration. Apply XL to within approximately 1/2" of the top and allow to settle. Within 30 to 60 min. (70°F) overfill joint with a second pass. Check joint occasionally to ensure low spots do not occur due to seepage.

Allow XL to cure, and then grind or shave flush or leave "crowned" if acceptable to owner and architect. Shaving is made easier by warming the cured XL with a torch or heat gun. Do not scorch.

Clean-up
Before XL cures, clean all tools, equipment, and spillage with solvent (Toluol, Xylol, Mek, or Acetone). For skin contact use SBS#33 cleaner or equal.

14. MAINTENANCE
Once XL is in place and cured it is basically maintenance free. If XL is installed in a floor that has not completed its entire shrinkage process, or if it is installed in a joint subject to movement, a void will likely occur. The void may occur adhesively or cohesively. This should be construed as a normal function of the XL and not considered a failure. See tech sheet on Separation.

To correct the condition, remove dirt and debris, vacuum or blow clear, and refill the void with additional XL or Spal-Pro 2000

16. SHELF LIFE
XL has a guaranteed shelf life of 180 days if the two components remain separate and sealed. Actual shelf life is longer. Turn cans upside down each month.

17. SAFETY/CAUTION
XL contains epoxy resins and alkali amines, both of which are strong irritants. Keep away from children and avoid contact with skin and eyes. Use only in ventilated areas and avoid inhaling the fumes. Always use appropriate safety equipment including rubber gloves, eye protection, protective skin creams (such as Kerodex, etc.). If contact is made with skin, thoroughly rinse with soap and water. If irritation occurs, contact a physician. If contact with eyes occurs, rinse immediately and continuously with clear water. Call a physician. When grinding cured material use proper dust mask and other safety equipment.

- IMPORTANT CAUTION-

Some people are sensitive to any contact with epoxy. If a person shows any evidence of sensitivity (rash, troubled breathing, etc.) he should be permanently removed from all epoxy exposure. The effects of epoxy sensitivity do not abate with time away from exposure but are cumulative. Refer to Material Safety Data Sheets.

All chemicals, including products made by our company and our competitors, have the potential to contaminate exposed food, packaged food and food packaging supplies. Contamination can occur if goods are present when the chemicals are used, or if goods are brought into the affected area after use but prior to removal of any residual contamination. USDA, FDA and other laws and regulations may require the removal or careful protection of food and supplies, followed by possible odor removal and/or cleaning of room where chemicals are used or stored. It is the responsibility of the user to be familiar with and adhere to all applicable laws and regulations. Assistance is available from many sources including the USDA (Karen M. Wesson, DVM, 202/720-5627). The user is further advised that Metzger/McGuire will reject any and all responsibility and claims that result from the improper use or storage of our products.
