New Freezer Floor Coating Stops Concrete Dusting

A new freezer floor coating developed by Roadware, Inc. can stop concrete dusting and restore freezer warehouse floors. Concrete dusting in your warehouse floor is a difficult challenge. Dusting is when the concrete surface deteriorates to powder due to heavy traffic, improper placement of the original concrete, mix design failure or a number of other reasons. Surface dusting can lead to hazardous conditions for personnel, unsanitary conditions and product contamination.  If the concrete is solid beneath the surface, these slabs can be made serviceable with specialized coatings. Coating slabs like this is even more challenging in a working freezer where temperatures are typically -20 degrees F (-29C).

Dusting concrete floors in a freezer can lead to unsafe and unsanitary conditions as well as contamination of product.

Concrete dusting can lead to the complete breakdown of the concrete wearing surface. Pallet jacks and forklifts can grind down the concrete allowing silica dust to become airborne and causing a health hazard.

Disbonded topping slabs and epoxy coatings can also create a hazardous dusting situation.

Hand grinders can also be used to remove the dusting surface. Dust collection systems are used to collect hazardous silica dust.

 

A craftsman mixes Roadware Freezer Floor Coating in a pail.
Roadware Freezer Floor Coating is easily mixed in a pail using a ratio of 1 part ISO, 1 part POLY and 1 part manufactured sand.

Roadware Freezer Floor Coating is mixed at a ratio of 1:1:1:

One quart A

One quart B

One quart 4030 grit silica or manufactured quartz sand.

Combined on a pail and mix with a paint stick or 10 seconds. Apply immediately. 

Coverage rate shown here is approximately 2.5 Meters Sq per mixed liter. 

Keep materials at outside the freezer at about 60-70 degrees before mixing.  Floor and air temperatures in the freezer for this project were -4 degrees F (-20C).

A single trowel down application is all it takes to provide a new surface to the concrete and good working floor. Product is applied at freezer operating temperatures. Product cures in several hours depending on the temperature and odor is very slight. Stand-up trowels may be used as well.
