Rapid Setting Crack Filler

Hybrid, quick-set, crack filler designed for injection into vertical or horizontal cracks in structural materials including concrete, bricks, and stone. It bonds, repairs and seals cracks, spalls, pop-outs and defects in heavy traffic industrial concrete floors. When cured, Poly-Strong PS 55 is a highly durable rigid structural polymer with a Shore D Hardness of 70-75. Very high adhesive and tensile properties; creates a long-lasting bond to the surface and outlasts many notable competing products. Odorless and non-hazardous.

Easy to Apply

Designed for industrial concrete applications such as exposed concrete floors, warehouse floors and retail floors. Used to fill cracks on interior, vertical or horizontal concrete surfaces.

Suitable For

Concrete / Exposed Concrete
Interior Floors / Retail Floors
Industrial / Commercial Floors
Retail Floors / Freezer Floors
Crack Repair in Old Floors
Garages / Auto Repair Shops
Basement Floors

Not Suitable For

Exterior Concrete

Available Colored

Available in a variety of colors, the PS 55 maintains a consistent color profile and resists fading or discoloration under normal conditions. This revolutionary new chemistry provides for superior substrate adhesion, moisture tolerance and better finished profile compared to similar polyurea crack fillers.

Application

For complete application instructions please download the Technical Data Sheet (TDS)

Surface Preparation

Repair area should be completely free of dust, debris, dirt, oils and moisture prior to application of material. Allow concrete to fully cure at least 28 days prior to installation.

Application Temperature

Material should be preconditioned to 70-80F prior to use for best results. Poly-Strong PS 55 is designed for use in concrete floors at temperatures of 32F or higher. If concrete temperature is lower than 32F, temporary heat tenting, etc. must be used to warm up floor area prior to installing material.

Application

Shake well before use (at least 45 seconds).
Unscrew cap and pull plug off. Allow cartridge to sit upright for several minutes for liquid to settle and for cartridge to “de-air”. 3. Insert flow restrictor into top ports. Place static mixer onto cartridge neck and secure rightly with lock nut.
Using a standard / univeral caulking gun, pull back gun piston and securely place cartridge into cradle.
Holdiing gun upward at a 90 degree angle, slowly pull trigger to purge air from cartridge. Drive material towards the top of mixer tip.
After material reaches top of static mixer, tilt gun down and squeeze the first 3-4 short of material into a disposible cup, etc. until color appears consistent in nature. Note: Gun should remain pointed down throughout dispensing of cartridge. DO NOT POINT GUN STRAIGHT BACK UP UNTIL DISPENSING IS COMPLETE. As material may run back into cartridge and some material many not cure properly.

Surface Defects/Spalls

Remove all loose concrete chips, spalls, islands, etc. back to structurally sound concrete with a hammer and chisel or dry cut saw equipped with diamond blade. Slightly overfill defect and monitor the installation for any seepage. If seepage into defect is detected, dispense additional material to restore flushness with surface. After Poly-Strong PS 55 cures into a hard solid (approximately 25 minutes) grind off any excess flush with surface using a cup grinder with medium grit pad or hand grinding stone.

Anchor Bolt Holes

If anchor is still intact, cut off as much of the bolt as possible prior to slightly overfilling defect with Poly-Strong PS 55.

Random Cracks

Cracks up to 1/8” (3 mm) in width should be cleaned using a Nyalox or soft wire wheel or brush and vacuumed prior to filling with neat Poly-Strong PS 55. Fill/overfill crack with neat Poly-Strong PS 55 and grind off any high spots after cure. For cracks wider than 1/8” (3 mm) or cracks where continual movement is suspected, an alternate recommended repair method is to rout out the crack using a diamond blade to a depth of 1/2” (12 mm) to 3/4” (18 mm) and filling the crack with a semi-rigid filler, such as our Poly-Stong PS 80 Joint Filler.

Drying Time:

Gel Time: 1 minute Tack Free: 5 minutes Traffic Ready: 15 minutes

Shelf Life:

One (1) year in tightly sealed, unopened container.

Limitations

Poly-Strong PS 55 is a structural repair product and should not be used as a floor joint filler. Poly-Strong PS 55 is a structural repair product with very high adhesive and tensile properties; consequently it will restrain concrete movement wherever placed and may lead to concrete tearing if substantial concrete movement occurs after placement. Poly-Strong PS 55 is not designed for use in temperatures below 32F. Poly-Strong PS 55 overfill may leave a light stain/shadow on some concrete surfaces. Poly-Strong PS 55 may exhibit a moisture reaction on damp or wet surfaces; repair area should be clean and dry.
