PERCOL Elastic CementTM - MACHINE DISPENSED - Rapid CONCRETE Repair

To repair concrete, two thin liquids are combined in equal volumes then flooded over aggregate:  In less than two minutes the liquids solidify; in ten minutes, repairs support traffic.  Rapid repairs with Elastic Cement and Concrete Welder are 4 to 10 times faster than conventional concrete repairs.

Elastic Cement provides a long lasting flexible repair where vibration and movement is encountered.  Concrete Welder (a very thin liquid) is used in wide and narrow cracks, and in spalls to provide high compressive strength repairs.

PERCOL Elastic Cement TM
Product Description
 

PERCOL Elastic Cement, with aggregates forms a high performance, rapid setting polymer concrete.  Within ten minutes of placement, durable, long lasting repairs (that withstand vibration, heavy traffic loads, and thermal movement) are ready for traffic. Solidifies in  less than two minutes... The reaction is fast.  Thin, equal volume, "A" and "B" side liquids are metered, combined, and pumped through PERCOL dual component dispensing equipment.  The reactive mix is PERCOLated over

aggregates and solidifies in less than two minutes.  It cures to a flexible polymer concrete suitable for spall and pothole repair, matching grades, smoothing rough pavements, and eliminating rutting.  Feathered repairs provide transition for mismatching grades of adjacent slabs.  Thin overlays easily formed... Concrete damaged by overloading, freeze/thaw spalling, or fires is easily resurfaced.  Decks are sealed and waterproofed.  High traction surfaces are easily created.

THE PERCOL ADVANTAGE

Bonds without Primer	No priming is required for bonding to concrete, steel or wood.
Seals and Protects	Creates flexible waterproof repairs that protect concrete from freeze/thaw spalling and stop corrosion of reinforcing steel.  Smoothes rough surfaces.  Restores traction surfaces.
Fast Repairs and Cure	Solidifies in less than 2 minutes.  Traffic ready within 10 minutes of placement.
Repairs Year Round	Successful repairs in freezing weather or in the heat of summer.
Safe to Use, No Odor	PERCOL Elastic Cement has a high flash point, contains no peroxides or heavy metals, and is odorless.  There are no toxic fumes during application.

PACKAGING 

"A" and "B" components are packaged in equal volumes in 55 gallon drums, 15 gallon barrels, or 5 gallon pails.  Shelf life is 12 months in unopened

containers stored indoors.  For small jobs apply PERCOL Elastic Cement from 21 or 53 ounce cartridge kits with hand operated dispensing guns.

 INSTRUCTIONS

Read Material Safety Data and the Installation Instructions before using product.  PERCOL Elastic Cement can be used in summer or winter.  For best performance, install at 20 degrees F. to 100

degrees F. ambient temperature and 60-80 degrees F. material temperature.  Do not apply during rain or on wet surfaces.

BULK APPLICATION EQUIPMENT 

PERCOL dual proportioning system transfers, meters, mixes and applies PERCOL Elastic Cement.  "A" and "B" components are transferred from drums, through the proportioning pumps, (1:1 ratio)

to the dispensing gun.  Material is mixed at the gun, then dispensed into the concrete surface to be repaired.

 PERCOL ELASTIC CEMENT APPLICATIONS

Spall & Pot Hole Repair Remove loose and unsound concrete by jack-hammering. Blow out dust with dry compressed air. Fill with clean, dry, dust-free crushed rock to grade. Flood with PERCOL Elastic Cement. Broadcast dry sand for high traction surface and to match deck appearance. Bridge Deck Overlay Repair Saw cut damaged overlay and remove. Sandblast deck surface. Place crushed aggregate level to surface Flood with PERCOL Elastic Cement. Broadcast dry manufactured sand to match deck texture.

Bridge Deck Overlays Repair spalls and cracks. Shot blast deck to clean deck surface and expose aggregate. Spray 30 - 40 mils of PERCOL Elastic Cement & cover with uniformly graded, clean, dry aggregate (3/16" to 1/4"). Remove excess aggregate.  Cover first aggregate layer with PERCOL Elastic Cement then cover again with aggregate. Remove excess aggregate Cover with light coat of PERCOL ELASTIC CEMENT to secure aggregate. Restoring Traffic With PERCOL Elastic Cement, traffic can resume within 10 minutes of completion of work
