Applications & Uses

- Compatible Substrates & Surfaces
- Surface Preperation
All surfaces to be coated should be dry and cleaned as necessary to remove all contamination.
Concrete:- Do not apply to newly laid concrete. Concrete surfaces to be coated should be at least 4 weeks old and have a moisture content of less than 7%.
- It is recommended for optimum coating lifetime that laitance is removed before painting, by (ideally) vacuum blast cleaning (to produce a profile suitable for the coating thickness to be applied); grinding; or acid etching (to produce an open, granular surface). If acid etching, thoroughly wash down and allow to completely dry before coating.
- Smooth, power-floated concrete surfaces do not provide good adhesion for painting, with coatings likely to detach after short periods. Smooth surfaces should ideally be treated as above, for laitance removal, to provide a good key for painting.
- Application Details
- Designed for application by brush, roller or squeegee.
- On bare concrete, thin the first coat by up to 10% to act as a sealer, before applying a full, unthinned coat.
- Excessively thick coatings will dry to a milky white appearance and are prone to softening when wet. The performance of the sealer is adversely affected by the application of excessively thick coatings. Two thin coats are better than one thick application.
- Mixing
Thoroughly stir the coating before use. A power mixer is highly recommended. A widebladed stirrer is essential for adequate mixing if only hand stirring. Stir occasionally during use to maintain a homogenous mix.
- Thinner/Cleaner
Clean water.
- Application Conditions
Throughout the application and the drying/curing time of coatings: (a) good ventilation isrequired; (b) do not apply when damp weather conditions are likely; (c) the substrate temperature should be at least 3ºCabove the Dew Point; and (d) the RH (Relative Humidity) should be below 85%. Do not apply the product when the ambient temperature falls below 10ºC. The paint temperature at the time of application should ideally be 15ºC- 20ºC.

Note
- Foot traffic can be allowed on the coated area after 24 hours, and heavier traffic after 72 hours at 20oC.
- Concrete floors are always several degrees colder than the ambient temperature, and on cold days, drying times will be extended.
- Keep coated areas dry for a minimum of 24 hours following application. Slow drying is usually attributable to either low temperatures, or the application of excessively thick coats of paint.
Storage & Handling
- Shelf Life
Minimum of 2 year from date of manufacture when correctly stored in unopened containers.
- Storage
The product should be stored in cool, dry, frost-free conditions, in sealed containers. Most paint materials will apply optimally when at 15ºC- 20ºC.
