PENECRETE MORTOR

DESCRIPTION

PENECRETE MORTAR consists of Portland cement, specially treated quartz sand, and a compound of active chemicals. The active chemicals react with moisture and the by-products of cement hydration to cause a catalytic reaction, which generates an insoluble integral crystalline complex. These crystalline complexes grow in the presence of water and block the capillaries of the concrete and minor shrinkage cracks, thus waterproofing the concrete. Chemical activation begins when the powder is mixed with water and may take several days to completely block the capillaries, depending on ambient temperature and environmental conditions.



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 Patching and filling of routed out cracks Repairing of spalled and honeycombed areas.

ADVANTAGES

Can be applied to the positive or negative water pressure sides of a structure Resists strong hydrostatic pressure Seals cracks up to 1/64” (0.4 mm) Easy to use – needs only to be mixed with water prior to application Allows the concrete to “breathe” Can be skim coated or feather edged Can be applied to moist concrete Fast setting Inorganic – contains no polymers NSF 61 certified for use in potable water applications Non-flammable Resists abrasion and mechanical wear Freeze/thaw resistant Zero VOC - PENETRON powdered products contain zero volatile organic compounds and are safe for use both outdoors and in confined indoor spaces.


DIRECTIONS FOR USE

Surface preparation:

All surfaces to be patched, repaired, or sealed with PENECRETE MORTAR 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” (19mm) 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 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 MORTAR 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. The 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 MORTAR 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 the surface with PENECRETE MORTAR 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 MORTAR™ 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 MORTAR in “dry earth” consistency. PENECRETE MORTAR 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 MORTAR has set (approximately 1-2hours). If this is not practical, leave the surface rough for subsequent surface treatment to bond.

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.


SPECIAL CONSIDERATIONS

DO NOT apply PENECRETE MORTAR™ at temperatures below 40ºF (4ºC), to a frozen substrate or if temperatures will drop below freezing during the curing period (approximately 24 hours). This product is not recommended for use in expansion joints or other joints designed for movement. PENECRETE MORTAR™ can be applied in 1/2" (13 mm) layers not exceeding 2.5“ (6.4 cm) to prevent shrinkage cracks in the mortar.
