C.I.A HI-BLEND  (High Build Sealer)
This sealer is generally used as a high build coating for C.I.A Topcrete. It is also used for sealing very porous concrete surfaces as it has a high solids: solvent ratio. 

C.I.A SUPERTHANE  (Two Pack Polyurethane)
Superthane is a high solids, high build, two pack polyurethane, specifically formulated to achieve a smooth hard wearing surface for flooring.

SEALER DO'S and DON'TS

The following list is a general guide to assist you in the success of sealer application for solvent based acrylic sealers.
If you are unclear or have concerns please contact C.I.A or your local Agent. It is always recommended that a test area be trialled first.

✔    Do ensure you have the correct sealer for your application.
✔    Do ensure the surface is clean, free of oil, loose particles and most importantly is completely dry. (24 hour minimum from last time the concrete/pavement was wet)
✔    Do acid etch closed concrete surfaces (e.g. Mirror finished by trowelling machine).
✔    Do allow sufficient drying time taking into account weather conditions (Minimum 6 hours dry conditions recommended after sealing)
✔    Do apply sealer thinly and evenly (two coats are far better than one heavy coat) (does not apply to Natraseal) C.I.A Ultra Sealer / Same Day - First Coat coverage is approximately 4m2 per litre.
✔    Do ask for advice.
✔    Do maintain the protective coat by reapplying sealer at regular intervals (18-24 months). (Longer for Natraseal & Superthane)
✔    Do inspect previous sealer coats for "MILKY whiteness", cracking or delamination and rectify before applying new coating.
 
✘    Don't apply sealer to damp concrete or moist concrete (concrete is porous and will hold moisture within its matrix even though it appears dry on the surface).
✘    Don't apply sealer in the middle of the day or to extremely hot surfaces (this may result in blistering and delamination).
✘    Don't apply thick coats (may lead to blistering, 'pork crackling', or failure to harden).
✘    Don't apply additional coat without allowing sufficient curing time.
✘    Don't apply more than two coats of C.I.A Ultra Sealer.
✘    Don't apply sealer over 'milky white', 'crazed' or delaminating sealer.

Note: Almost all sealer failures are the direct result of moisture presence or high temperatures at the time of application.
Application equipment should be cleaned with C.I.A Solvent.
