3. Product Description
Composition
Spal-Pro RSF is a rapid setting, two-component polyurea polymer liquid of 100% solids content.  When cured, Spal-Pro RSF is a gray, rubberlike solid with a hardness of Shore A85-94, depending on temperature.

Basic Use
Spal-Pro RSF was developed to fill and protect joints in freezer room concrete floors that are subject to hard wheels and heavy loads.  Its primary function is to support such traffic and support joint edges.  Spal-Pro RSF is designed for use in areas where final temperatures are from 32°F (0°C) to -25°F (-32°C).

Other Uses
Spal-Pro RSF is also ideal for filling random cracks in freezer floors.

4. Limitations
• Spal-Pro RSF should be installed only after installation areas are stabilized at final operating temperatures. Due to its relatively high Shore A hardness it will not expand if joints widen considerably as temperatures drop.
• Spal-Pro RSF is not recommended for the repair of wide (1"+) spalled joints, wide gouges or surface delamination.  Refer to data on Spal-Pro 2000 for such repairs.

5. Correct Joint Design/Installation
Spal-Pro RSF should be installed full depth in saw-cuts and 2" (50 mm) deep in construction (formed) joints that are not saw-cut, per PCA and ACI guidelines. Because of its rapid set, "choking off" the base of the joint is normally not necessary.  If shrinkage crack is excessive, it may be "choked off" as shown below (contractor's option). Do not use compressible backer rod (Ethafoam, etc.) in saw cut joints.  Compressible rod may be used 2" down in formed joints.

6. Color and Packaging
Standard color is medium (charcoal) gray.  Available in 10 gal. (US) kits (2-5 gal. US pails), 100 gal. (US) kits (2-50 gal. US drums), and
dual-cartridge convenience kits.

7. Applicable Specifications
There are no government or ASTM standards for floor joint fillers. 
Spal-Pro RSF meets and/or exceeds the floor joint filler guidelines  set forth by ACI 302 (Guide for Concrete Floor and Slab Construction, ACI report 302.1 R-96), ACI 360 and PCA (Concrete Floors on Ground, Ralph  E. Spears,  PCA).

8. Advantages
• Spal-Pro RSF is Rated "Heavy Duty"
    Unlike flexible polyureas,  RSF's higher shore hardness
    provides greater edge protection and support.

• Spal-Pro RSF is "Rapid-Setting"
    At  0°F (-18°C) it can be opened to full traffic in as little as
    (3) three hours and light traffic in (2) two hours.

• Spal-Pro RSF Will Not Become Brittle
    Even at temperatures far below freezing, RSF retains its
    hard, rubberlike character.

• Spal-Pro RSF is a "Superior Formulation"
   You get consistent cure and quality in all environments;
    no uncured strips, no soft, hard or uncured spots as with
    other polyureas.

• Spal-Pro RSF Comes with a "Legacy"
   For 30+ years, Metzger/McGuire has been the unequaled 
   leader in floor joint protection technology and technical/field 
   services and support.

9. USDA/FDA Approval
Spal-Pro RSF is acceptable for use in floors subject to USDA and FDA inspection and regulation.  See section 19 for additional information.

10. Technical Assistance
Complete technical support and literature are available from authorized distributors, through our web site (www.metzgermcguire.com) or by contacting our New Hampshire headquarters at (800)223-MM80.

11. Where to Specify and File
Spal-Pro RSF is exclusively for use in concrete floors and thus should always be referenced in 03251 (expansion/contraction joints) &  03300
(cast-in-place concrete).  It is not a sealant and should not be specified as part of 07900, other than for cross reference.

12. Quality Installation Programs
Metzger/McGuire offers quality installation assurance programs for qualified projects.  Contact Metzger/McGuire for specific information.

13. Availability
Spal-Pro RSF is available through quality construction supply distributors in most major cities (listing available at www.metzgermcguire.com) or through our New Hampshire headquarters.

14. Installation
The following instructions are abbreviated.  Complete instructions are provided with each shipment.

When to Install
Spal-Pro RSF should be installed only in areas below 32° F (0° C).  Room should be stabilized at final operating temperature for 24-48 hours prior to installing Spal-Pro RSF. 

Joint Preparation
Joints should be free of saw laitance, dirt, debris, frost and/or visible moisture.  Joint cleaning procedures must accomplish the removal of all of the above.  Failure to do so  could compromise adhesion.  Coating and sealers must also be removed from the inner joint walls.  No primer is needed.  Contact M/M if unusual conditions are suspected.

Choking off the base of the joint is normally not required due to Spal-Pro RSF's rapid set.  Applicator may at his option choke-off the shrinkage crack if it is excessively wide (as shown in joint design spec, section 5).  Do not use compressible backer rod (Ethafoam, etc) in saw cut joints.

Prior to Dispensing
Caution: Thoroughly read MSDS and complete installation instructions prior to opening containers or attempting to dispense.

Spal-Pro RSF must be dispensed with dual-feed power dispensing equipment, or with pre-filled, dual-dispense cartridge convenience kits provided by Metzger/McGuire.  Manual dispensing is impractical due to short working life (2-3 minute gel time).  Power dispensing systems should be set to a 1:1 ratio by volume, with lines and material tanks heated and insulated. Material should be maintained at a minimum temperature of 75° F (24°C) for best results.  We recommend the use of a 1/2" diameter (ID) 32 element static mixer. 

Material provided in drums or pails should be thoroughly mixed with drill and paddle to redistribute any settlement or pigment separation that may have occurred during shipping or storage.  Cartridges should be shaken aggressively. 

Dispensing
Fill joint from bottom to top, preferably using a dispensing tip that fits into the joint.  Take care not to entrap air bubbles.  Joint can be filled using either a one or two pass technique.  The RSF should overfill the joint, leaving a crowned profile, and allowed to cure.  The crown may be easily razored off in 1 1/2 to 3 hours, leaving a profile that is flush with the floor's surface.  If RSF razoring is delayed and becomes difficult to shave smoothly, apply a small amount of heat as you razor material off.

Should filler cure below the floor surface (due to settlement into the void at base of joint, etc.), wipe off surface of filler with solvent and apply additional filler.  Adhesion between beads is enhanced by roughening the surface of the first bead.

The overfill not removed during razoring may  leave a slight stain on concrete.  The degree of staining will depend on the surface density (porosity) of the slab.  The stain will gradually fade as a result of subsequent traffic and floor cleaning procedures.

Bubbles in Surface of Bead
Small bubbles may develop during the cure of the material.  These are generally due to the air entrapment. Bubbles may be "popped" by applying a flame prior to cure.  Small (pinhead, etc.) bubbles will not adversely affect Spal-Pro RSF's performance.

Clean-Up
Spills of unmixed components can be cleaned up with solvent (Toluol, Xylol, MEK , Denatured Alcohol, etc).  Cured product can be scraped or shaved off floor and tools.

15. Maintenance
Once cured, Spal-Pro RSF is basically maintenance free.  If joints should open wider after installation, fill the voids with additional Spal-Pro RSF.

17. Shelflife and Storage
Spal-Pro RSF  has a guaranteed shelf life of 180 days if containers remain unopened.  Store in dry, cool areas away from excessive heat, freeze/thaw and sunlight.  See complete installation instructions for info.

18. Safety
This product is for industrial use only. Use only in well ventilated areas.  Practice all normal jobsite safety precautions (clear work area, etc). Refer to MSDS and installation instructions for more information.

19. Food Related Facilities
USDA prohibits the use of any chemicals in areas where existing food or food packaging can be contaminated.  See "Food Warning" in installation instructions.
