GENERAL DESCRIPTION
STAR MACRO-DECK protects concrete bridge decks, abutments and other concrete surfaces against salt and damage from chemicals. STAR MACRODECK quickly penetrates concrete surfaces and forms a rubber network in the interstices that form while concrete cures out. STAR MACRO-DECK stops water, chloride de-icing chemicals, salt, and other damaging elements from entering the concrete surface.
OUTSTANDING PROPERTIES
• Inhibits chloride de-icing chemicals, salt and damage from chemicals to concrete.
• Maintains flexural and tensile strength of the concrete.
• Very easy to apply. Very fluid, water like consistency.
• Water-based, safe to handle and easy to store.
• Resistant to many hydro-carbons and other petrochemicals.
• Non-flammable
RECOMMENDED USES
STAR MACRO-DECK is recommended on all types of concrete surfaces; Concrete bridge decks, support structures, guard walls, median dividers, curbs, grain elevators, sanitary sewer, masonry walls and floors, airport taxiways and aprons.
Coverage Rate
200 – 300 Sq. Ft / Gal (4.9 – 7.3 Sq. Meter / Liter)
Will vary according to dilution.
Dilution Rate
The amount of water added to STAR MACRO-DECK will vary according to the porosity, age and profile of the concrete being treated.
General Dilution Guidelines for:
• Abutments: Dilution is NOT recommended.
• Bridge Decks: Mix with an equal volume of water (1:1)
• Older Bridge Decks: Either apply at full strength or apply pre-diluted in 1:1 ratio with water.
• ALWAYS: add water into STAR MACRO-DECK, not vise-versa
Application
GENERAL PREPARATION: Concrete must be clean, free of dust, grease, grime, mold, mildew and debris. Concrete must have a profile and a certain degree of porosity for STAR MACRO-DECK to penetrate effectively.
ON SMOOTH SURFACES: Etch with muriatic acid.
OIL AND GREASE CONTAMINATION: Remove by de-greasing and washing with detergent.
MOLD AND MILDEW: Remove using bleach wash or other suitable method
Application Tools
• Low pressure spray, brush or roller.
• Clean up with Water. Do not discard washings in the bodies of water or down sewer drains.
• Keep stored containers sealed tightly.
Curing Time
Cure time will vary according to temperature and humidity at the time of application. Lower temperatures, high humidity and lack of direct sunlight will prolong the cure time. Higher temperatures, lower humidity and direct sunlight accelerate the cure process. After the application allow the coating to cure at least 30 minutes under good drying conditions. Apply at the recommended application rates. Thick applications will require more time to dry and fully cure.
