Overview
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 0.5 mm (1/51 in)
- 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
- Nonflammable
- 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
Mixing
Routed cracks, coves and non moving joints: approximate mixing ratio (by volume) is 4.5 parts powder to 1 part water. Alternatively, 101 ml (3.4 oz) of water to 454 g (1 lb) of PENECRETE MORTAR™ powder.
Tie holes and pointing applications: add only a small amount of water. Mix only as much material as can be used within 20 minutes.
Technical data
Compressive strength (ASTM C109): 1 day 11 MPa (1600 psi), 3 days 17 MPa (2400 psi), 7 days 40 MPa (5800 psi), 28 days 48 MPa (6900 psi).
Tensile strength (ASTM C190): 1 day 2.2 MPa (320 psi), 3 days 3.6 MPa (520 psi), 7 days 5.0 MPa (730 psi), 28 days 6.2 MPa (900 psi).
All data derived from tests under laboratory conditions; field conditions may yield slightly different results.
Special considerations
DO NOT apply PENECRETE MORTAR™ at temperatures below 4ºC (40ºF), 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 13 mm (1/2 in) layers not exceeding 6.4 cm (2.5 in) to prevent shrinkage cracks in the mortar.
Packaging
22.7 kg (50 lb) bags.
Storage and shelf life
PENETRON products must be stored dry at a minimum temperature of 7ºC (45ºF). Shelf life is two years when stored under proper conditions.
