CONCRETE OVERCOAT (OC) Fact Sheet
Tech-Data Bulletin C-1.12
HAZARDS: Inhalation of dust, abrasion to eyes, drying of skin.
SAFETY: Wear NIOSH/OSHA approved dust mask. Wear gloves. Use eye protection. If eye irritation occurs flush with water. Do not rub eyes. Ammonia fumes from Acrylic Activator (mixing liquid) may cause headache. Remove to fresh air.
USE: Colored cementitious coating for concrete, plaster, drywall, saltillo tiles and other clay and cementitious products such as brick, some applications over metals or over paint or glass, when paint thickness or less is desired. Ideal for color wash and faux painting.
MIX RATIO: 6 parts (OC) powder to 5 parts Acrylic Activating Liquid. If sponge application leaves lines add more liquid (Acrylic Activator). If application fails to cover adequately in two coats add more powder.
COVERAGE: 1 pail, 10 pounds, of powder with the appropriate amount of Acrylic Activator, applied with a masonry sponge over structurally sound concrete yields approximately 400 square feet in two coats. A color wash or faux finish yields many, many times as much coverage. Porosity or profile will affect coverage.
SUBSTRATE: Concrete, plaster, drywall, some bricks and tiles, latex paint, some metals, glass.
FINISH: Smooth paint type surface. Ideal for multi-color designs and finishes, logos, artwork.
COLORS: 36 standard colors, Custom color matching available, Many popular matches available.
APPLICATION: DO NOT APPLY BELOW 50F (10C)
Mix with a high speed drill mixer and Squirrel Mixer bit (1 gallon size) by adding powder to liquid. Mix until lump and streak free. Apply with a masonry sponge in a circular motion taking care to accomplish complete coverage.
Concrete Overcoat (OC) may be applied with a pump-up type hand sprayer taking care to agitate by shaking sufficient to prevent settling of the pigments in the canister. Concrete Overcoat (OC) may be applied with a pressure pot equipped with an agitator bar for large applications.
CURING: Allow 24 to 72 hours for curing at 50F (10C) or higher.
SEALING: Concrete Overcoat (OC) may be sealed with either Permaglaze Acrylic Lacquer or Permashield. See Tech-Data Bulletins S-3.10 and S-3.20 for information.
STORAGE: Keep closed and dry, out of direct sunlight and inaccessible to children.

Spills and Disposal: Collect spilled powders and place in containers. Avoid generation of dust. Dispose in accordance with local, state, and federal regulations for disposal of non-hazardous wastes.
General Precautions: Avoid dust, skin and eye contact. Avoid dust inhalation.
Section 8 Control Measures
Respiratory Protection: When working with or near this product, all personnel must wear MSHA-NIOSH approved respirators. Refer to OSHA standards in 29 CFR 1910.134. Use local exhaust to keep exposures below OSHA PEL’s for silica and nuisance dusts.
Personal Protective Equipment: Goggles or glasses, gloves and aprons
Section 9 Special Precautions
Good industrial practice requirest that employee exposure be maintained below the recommended TLV and as low as possible.
This is achieved by use of the approved respirators at all times and good hygiene, namely washing or bathing after each use and
Washing clothing after each use.
D.O.T. Classification—non-hazardous. Not required. Class 55.
