ProGrout (formerly 4034) Polyurea Concrete Quick Repair | Ultra Low Viscosity | Apply Low Temp -20°F | Low Odor

MIXING AND APPLICATION INSTRUCTIONS

Preparation

Concrete must have a minimum 28 day cure prior to application. The area must be dry. Clean the surface and remove all unsound concrete, dust and debris. Prepare surface using a dry diamond blade or a twisted wire wheel for spalls. Cut perimeter of damage with dry diamond blade to form a key- way. Cracks; open the crack to provide some depth to the crack to allow the product to penetrate deep into the crack.

APPLICATION METHODS

Application in Bulk

Mix ProGrout at a 1:1 ratio (A&B). Use a Jiffy Mixer or other multi blade mechanical mixer. No paddle mixers. Mix part A and B mechanically at high speed for approximately 30-40 seconds.

Use mixed product as a primer for the bottom of the repair.

Improper mixing may result in product failure.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

Preplacing Method (typically smaller crack repairs)

Prepare the area and add mixed ProGrout product to the sides and bottom of the repair area as a primer. Add #30 Grit select sand into the repair. If the repair is deep work in layers adding sand as product is added. As the product saturates the sand, add more sand and product.  Finish with a broadcast of sand slightly above grade and grind as needed for a completely smooth surface with surrounding area.

The preplace sand method can be done purchasing ProGrout in both bulk 2 gallon and 10 gallon kits.

Grout Repair (typically larger repair areas)

Prepare the area and add mixed ProGrout product to the sides and bottom of the repair area as a primer.  Then add one part of mixed (A&B) product to two parts select sand, i.e., 1 pint of A + 1 pint of B added to 2 quarts of sand. Blend mixed product into sand quickly. Mix product and sand for another 30 seconds and immediately pour into the prepared and primed application area. Work into the repair area quickly. Screed to finished grade and allow to set, top surface with product as needed, broadcast additional sand as needed.

For better finished repair surface, pour grout mix slightly high above the finished grade. Allow product to set and grind using a grinder fitted with a Zec wheel. Work in circular motion to grind/smooth to finished grade. Seal the surface using mixed product neat with no sand.

Set time is predicated on the temperature of the substrate. Typically the product will gel in 4 to 5 minutes at about 70 degrees F. The product will harden in 10 to 15 minutes and the ports can be removed. Seal the blemish left by the port using the 830. Sand, sack or finish as needed prior to coating the surface.  Exterior applications should be ground and allowed to set for 1 to 2 days before coating.

Cleanup

Use xylene or equivalent solvent to clean up application tools

Set Time

Three to four minutes, hard for traffic in about fifteen minutes, final cure 24 hours. For more working time in cold conditions pre-condition the product in the freezer or cold area prior to use about 45 minutes.  Cold Conditions Pre-condition the product temperature for use at cold temperatures @ approximately 70F or to slow product set time keep product cool or cold.

LIMITATIONS

• Do not use on wet surfaces or expose part A to moisture prior to application  This product is moisture sensitive and should not be applied to wet surfaces
• The ProGrout is not intended as a joint filler.  If used as a joint filler, thermal cycles may cause a crack along the sides of the joint.   Likewise, reflective cracking may occur if used as a joint filler and the joint is over coated, showing a crack through the topcoat.
• Product may bond damaged slabs together and may stop movement.  Not intended for use where substrate movement is required
• Product will cure considerably faster in warm or hot conditions and slower in cold conditions.  Do not use a product that is hot.
• ProGrout can be top coated with the 5500 Polyaspartic, however, in areas where the repair and top coat will be exposed to direct sunlight, shadowing or staining of top coat can occur In these areas allow the set product, after it has been ground, to be allowed additional cure time to avoid future staining.
• ProGrout can be used outside but due to differences in the repair product density compared to that of the concrete, a small hairline fracture may develop along the bond line of the repair and the concrete. ProGrout is an aromatic product and will discolor when exposed to UV but will not be physically changed.
