DIRECTIONS FOR USE

Surface preparation:
All surfaces to be patched, repaired or sealed with PENECRETE MORTARTM must be clean and sound. Cracks should be routed out to a U-shaped configuration, approximately 3/4” (19 mm) wide and a minimum of 3/4” (19 mm) deep. Tie holes should be roughened prior to filling. Spalled and honeycombed areas must be thoroughly cleaned and chiseled back to sound concrete prior to repair. Remove all dirt, cement laitance, form release agents, curing compounds, paints, coatings, etc. by means of wet or dry sandblasting, high pressure water jet or other suitable mechanical means. Surfaces must be well moistened to a dull dampness at the time of application. The concrete should be damp with no wet sheen on the surface.

Mixing:
Routed cracks, coves and non-moving joints: Add water to PENECRETE MORTARTM until a medium stiff, trowelable consistency is reached. The texture of the mix should be pliable enough to be trowelled into the cracks with some pressure, but not so pliable that it would run out or sag out of the crack. Approximate mixing ratio (by volume) is 4.5 parts powder to 1 part water. Alternatively, 3.4 oz (101 ml) of water to 1 lb (454 g) of PENECRETE MORTARTM powder. Tie holes and pointing applications: Add only a small amount of water. Mixed consistency should be that of “dry earth,” holding a shape when squeezed in your hand but easily crumbled when pressed between fingers. Mix only as much material as can be used within 20 minutes.

Application:
Cracks/seal strips (reglets & coves): After proper surface preparation and routing to appropriate configuration, prime areas to be patched or repaired with a slurry coat of PENETRON® and while “green” (tacky), fill cavity flush to surface with PENECRETE MORTARTM in mortar consistency.

Spalled and honeycombed areas:
Prepare surface and chisel back to sound concrete. Prime area to be repaired with a slurry coat of PENETRON®. While still “green” (tacky), apply PENECRETE MORTARTM in layers of 1/2” (13 mm) not to exceed 2.5“ (6.4 cm). Each layer should be allowed to set long enough that it will leave only a slight indent, approximately 1/16” (1.6 mm) when pressed with a finger. Where possible, the surface of the repair should be packed tightly using a hammer and block of wood.

Tie holes and pointing applications:
Prepare surface and chisel back to sound concrete. Prime area to be repaired with a slurry coat of PENETRON® and while still “green” (tacky), apply PENECRETE MORTARTM in “dry earth” consistency. PENECRETE MORTARTM should be tightly rodded into tie holes or packed tightly using a hammer and block of wood.

NOTE:
For all applications, PENETRON® should be applied as a surface treatment as soon as PENECRETE MORTARTM has set (approximately 1-2 hours). If this is not practical, leave surface rough for subsequent surface treatment to bond. Repairing of spalled and honeycombed areas

Curing:
Provide protection against extreme weather conditions, such as heavy rain or freezing conditions, during the setting period. Curing is not normally required except during hot, low humidity weather. In these conditions, a light mist of water approximately 24 hours after the repair is completed will help to ensure a controlled cure. In extreme dry heat, water misting may be required more frequently.
