PRODUCT DESCRIPTION

• Colorless
• Odorless
• Non-toxic
• Non-combustible
• Non-flammable
• Contains NO Volatile Organic Compounds (VOCs)

USES

• Concrete, new and old, rough or smooth surfaces
• Concrete block
• Exposed aggregate
• Any sand/aggregate cement combinations

FUNCTIONS

• Seals, dust proofs, hardens, and cures
• Protects against dusting, pitting, palling, efflorescence, temperature cracking in concrete
• Inhibits freeze/thaw deterioration
• Neutralizes excess internal alkali from concrete

PACKAGING

• 55 Gallon / 208 Liters Drums
• 5 Gallon / 19 Liters Pails

STORAGE LIFE

• Two years; agitate drum or pail before using

SURFACE PREPARATION

• Freshly Finished Concrete: no preparation required
• Existing Concrete: sweep, scrub, or strip concrete to remove any surface contamination or film; product must be able to penetrate the surface without hindrance

APPLICATION

• Single application only; apply with low-pressure sprayer (power), rollers, brush, or fine/soft bristled broom

COVERAGE RATE

• Approximately 200 ft²/gal (5 m²/L); coverage depends on the the temperature and porosity of the concrete

CLEAN-UP

• Soap and water

DRYING TIME

• One to three hours; the surface may be used as soon as the application is complete and the surface is again dry to the touch; newly laid surfaces require the normal hardening period

APPEARANCE AFTER APPLICATION

• Smooth Troweled Concrete: permanent, marble-like sheen develops within 4-12 months; burnishing the concrete surface with a propane burnisher will accelerate the sheen
• All Other Concrete Surfaces: retention of natural finish

TEMPERATURE LIMITS

• Apply in temperatures up to 135º F/57ºC or as low as 35ºF/1.7ºC if the concrete is covered by plastic and completely protected from freezing for a period of 6 days

THINNERS, PRIMERS AND PAINTING

• No thinners or primers required
• Painting on New Concrete: allow at least 7 drying days before applying quality grade paint on existing concrete
• Painting on Existing Concrete: allow 28 days for proper curing before painting new concrete

COLORED CONCRETE

• Apply to colored concrete only after the slab is fully cured; do not get on glass or other finished surface

LIMITATIONS

• Do Not Apply the Ashford Formula to:
  • Lightweight block or other extremely porous masonry containing actual holes or air pockets
  • Areas previously treated with curing or sealing agents, unless these coatings have completely worn off or have been removed by chemical or mechanical means
