DESCRIPTION
HIAC acrylic concrete sealer is an acrylic co-polymer solution that dries to a clear, colourless, abrasion-resistant film. It is highly resistant to stains, acid, oil, grease, most industrial chemicals, and de-icing salts, and will not yellow the concrete.
USES
HIAC is used for protection of old or new concrete from weather, chemical attack, staining, and dusting. HIAC imparts a medium-to-high sheen, dependent upon the number of coats applied, which enhances the natural concrete colour.
Suitable applications include concrete driveways, patios, exposed aggregate, and all exterior cementitious surfaces.
HIAC may be applied over CS-309™ curing and sealing compound from W. R. MEADOWS after the concrete has cured at least seven days to give a highly effective curing and sealing system.
HIAC may be re-applied as traffic patterns appear.

APPLICATION INSTRUCTIONS
Product container provides all application information. Read and follow all instructions and precautions. Concrete must be clean and dry prior to HIAC application.
Remove stains and discolourations.
New concrete should be properly cured for a minimum of seven days prior to HIAC application. (CS-309 is compatible.)
Apply by spray, brush, or lamb's wool applicator in a uniform film.
For greater sheen, apply additional coats after preceding coat has dried. Avoid over application and excessive build-up.
Avoid puddling in low areas. Restrict foot traffic for at least four hours. Twelve hours is preferable.
HIAC should not be applied during high temperature conditions in direct sunlight. These conditions cause rapid evaporation, which does not allow the film to form properly. Under these conditions, the film may peel, bubble, and/or turn white (blush).
Should not be applied to concrete exposed to excessive moisture. Entrapped moisture in a solvent-based sealer may cause the film to peel and/or turn white (blush).
*Note: In cases when HIAC is applied to existing concrete surfaces (more than 28 days old), the variations in coloration of the sands and aggregate present in the existing surface may be enhanced causing the surface to appear discoloured.
CLEANUP
Clean tools after use with a solvent such as SEALTIGHT SOLVENT, xylol or toluol.
PRECAUTIONS
Use only when concrete surface temperature is above 5°C (40°F) and surface is completely dry. Remove existing curing compounds (except CS-309; see above) before application.
Keep vapours away from foodstuffs. Not resistant to aromatic solvents. Will not resist spillage of lead-free gasoline. Will temporarily darken concrete; lightens to normal concrete colour in 6 - 12 months. HIAC is flammable. Keep away from heat and open flame. Avoid prolonged contact with skin. Use with adequate ventilation and avoid prolonged breathing of vapour.
SAFETY AND TOXICITY
Contains solvent. Use with adequate ventilation and avoid prolonged breathing of vapours that may cause dizziness or suffocation. Avoid contact with skin and/or eyes. See product label and Material Safety Data Sheet for additional information. Read and follow all instructions and precautions.
Harmful or fatal if swallowed.
