RECOMMENDED INSTALLATION PROCEDURES
Crafco HP Concrete Cold Patch is a unique, gray-colored, cold-applied patching material
used to repair potholes, spalls, cracks, and other conned voids and distresses over 1" wide (2.5 cm)
and greater than 1/2" (1 cm) deep in Portland cement concrete and oxidized asphalt. It can be used
on roads, highways, streets, airport pavements, parking lots, bridge and parking decks, sidewalks,
walkways, and oors. No mixing, heating, or special installation equipment is required.
INSTALLATION
• Clean, sweep, and blow the repair area free of all loose debris before applying.
• The repair area surfaces can be damp but should not have standing water or ice present
during installation.
• Remove HP Concrete Cold Patch from the bag and place it into the prepared repair area.
• For best performance, HP Concrete Cold Patch should be applied with at least 1/2" (1 cm) in
thickness. For repairs 1/2" (1 cm) to 2" (5 cm) thick, apply product in a single layer and compact.
Repairs deeper than 2" (5 cm) should be lled in layers, from 1" (2.5 cm) to 2" (5 cm) thick, with
compaction of each layer. The nal layer should be placed approximately 1/4" (.6 cm) to 1/2" (1 cm)
above the surface, and then be compacted to surface level with a hand or mechanical tamper or
multiple passes from a vehicle tire.
• Following compaction, clean up any excess HP Concrete Cold Patch and open pavement to tra󰀩c.
If needed in warm climates, initial surface tack can be reduced with a light sprinkle application of
Portland cement, calcium carbonate powder, or ne sand over the compacted surface.
HP Concrete Cold Patch should be installed when pavement temperatures are between 30°F (-1°C)
and 100°F (38°C). If applying when pavement temperatures are below 30°F (-1°C), the repair area can
be warmed to at least 30°F (-1°C) using a Crafco Hot Air Lance™ or a torch. HP Concrete Cold Patch
can be stored in a warmer area, not exceeding 90°F (32°C), prior to use, to improve workability.
STORAGE
Pallets and bags of HP Concrete Cold Patch should be kept intact and stored under cover. Shelf life
of properly stored product in unopened pallets and bags is up to one year. To maintain workability,
leftover HP Concrete Cold Patch from an opened bag should be placed in an airtight container such
as a pail or bucket with a tight-tting lid.
