DESCRIPTION
HIAC-PLUS 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.
USE
Protection of old or new concrete from weather, chemical attack, staining and
dusting. HIAC-PLUS 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 panels, and interlocking concrete pavers - all exterior cementitious surfaces.
HIAC-PLUS may be applied over CS-309™ Curing and Sealing Compound by W. R. MEADOWS (see Data Sheet 3300-201), after the concrete has cured at least seven days, to give a highly effective curing and sealing system.
HIAC-PLUS may be re-applied as traffic patterns appear.
FEATURES
High acrylic content for positive weatherproofing, stainproofing and dustproofing
qualities.
High resistance to oil, grease, de-icing salts; hydrochloric, acetic and sulphuric acids; caustic sodas and most industrial chemicals and aliphatic solvents.
High or medium sheen - Quick drying.
Floors sealed with HIAC-PLUS can
later be painted (consult reputable paint manufacturer for compatibility) or
covered with resilient flooring, if desired.
CAUTION
|
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 to 12 months. HIAC-PLUS is flammable - keep away from heat and open flame. Avoid prolonged contact with skin. Use with adequate ventilation and avoid prolonged breathing of vapour. |

Concrete must be clean and dry prior to HIAC-PLUS application. Remove stains and discolourations.
New concrete should be properly cured for a minimum of seven days prior to HIAC-PLUS application (CS-309 is compatible).
Avoid application on pavers, on grade, during midday periods of direct hot sunlight or periods of high humidity - apply in late afternoon or when sun is obscured by clouds.
Protect grass, shrubs, etc. from the solvents in HIAC-PLUS.
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 4 hours; 12 hours is preferable.
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-PLUS 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 dis-coloured.
CLEAN UP
Clean tools after use with
a solvent such as SEALTIGHT Solvent, Xylol or Toluol.
Proper application is the responsibility of the user. Field visits by W. R. MEADOWS personnel are for the purpose of making technical recommendations only, and are not to supervise or provide quality control on the job-site.
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.
