PENECRETE MORTAR
PENECRETE MORTAR is a cementitious, ready-mixed waterproof repairing and sealing mortar. It consists of Portland cement, specially treated quartz sand and compound of active chemicals, which resist water pressure.
Recommended Applications
Applied in conjunction with PENETRON for:
*Installation of seal strips reglets and coves) at joints to assure water tightness
*Patching of tie holes and faulty construction joints.
*Filling of routed out cracks
*Waterproof sacking of concrete "bugholes"
Repairing of spalled and honeycombed areas
Advantages
*Applied to the positive or negative water pressure side of a structure
*Resists strong hydrostatic pressure
*Post sealing effect of shrinkage cracks up to 0.01" (0.3mm)
*Easy to use - needs only to be mixed with water prior to application
*Not a vapor barrier, lets concrete "breathe"
*Can be skim coated or feather edged
*Applied to moist concrete
*Fast Setting
*Inorganic - no polymers
*Non-Flammable
Properties
The active chemicals combine with the free lime and moisture present to form insoluble crystalline complexes. These crystalline complexes, similar to a gel that grows in the presence of water, block the capillaries of the PENECRETE MORTAR and minor shrinkage cracks, thus preventing water ingress. Chemical activation begins when PENECRETE MORTAR powder is mixed with water and may take several days to completely block the capillaries depending on ambient temperature and environmental conditions.
Preparation of Substrate
All surfaces to be patched, repaired or sealed with PENECRETE MORTAR must be sound
*Remove all dirt, cement laitance, form release agents, curing compounds, paints, etc. by means of wet or dry sandblasting, a high pressure water jet or other suitable mechanical means.
*Surfaces must be well moistened to a dull dampness at the time of application.
*Cracks should be routed out to a U-shaped configuration, approx. ¾" (20mm) wide and a minimum of ¾" (20mm) deep.
*Tie holes should be roughened prior to filling.
*Spalled and honey- combed areas must be thoroughly cleaned and chiseled back to sound concrete prior to repair.
Mixing
PENECRETE MORTAR should be mixed with clean water to a trowelable mortar consistency. Approximate mixing ratio (by volume) is
*4 ½ parts powder to 1 part water*
For glove pointing add small amount of water. Mix only as much material as can be used within 20 minutes.
Application
NOTE: Do not apply PENECRETE MORTAR at temperatures below 400F (50C) or to a frozen substrate. This product is not recommended for use in expansion or construction joints.
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 MORTAR in mortar consistency.
Spalled and Honey Combed Areas
Prepare surface and chisel back to sound concrete. Prime area to be repaired with a slurry coat of PENETRON and while "green" (tacky), apply PENECRETE MORTAR in layers of ½" (12.7mm) until desired profile is obtained.
NOTE: PENETRON should be applied as a surface treatment as soon as the PENECRETE MORTAR has set (approx. 1 - 2 hours). If this is not practical, leave surface rough for subsequent surface treatment to bond.
