Areas to use Oncrete SV50 Water Based Epoxy
Oncrete SV50 Water Based Epoxy is designed to be used as a primer, or as a finish coat for internal concrete walls and floors. Oncrete SV50 is commonly used as a base coat for flake chip epoxy flooring systems. Because of its low VOC formula, SV50 is also suitable to be used in food and beverage areas. SV50 Water Based Epoxy can also be used as a garage floor paint due to its ease of application and excellent durability.
- Low VOC formula;
- Good abrasion resistance;
- Good chemical resistance; and
- Available in a wide range of colours.
PREPARATION & CLEANING
Ensure concrete is sufficiently cured (recommended minimum 14 days). The surface requires cleaning to remove any substance which could affect adhesion (example: concrete sealer, paint, algae, mildew, mould, oil or grease). Once substances are removed, wash down area using a heavy duty cleaner, acid etch with a hydrochloric solution of 10 parts water and 1 part acid. Pressure clean using clean water. Ensure all acid is neutralised and removed. Allow to dry thoroughly before applying product. If it is not possible to acid etch the surface, then it must be abraded until the surface has a rough texture adequate for the epoxy to adhere to. Holes and cracks should be filled using an appropriate epoxy filler.
MOISTURE / DRY TEST
Using a calibrated moisture meter, ensure the concrete has less than 20% moisture content prior to sealing.
Mix equal parts of PART A and PART B together. While mixing scrape both the sides and bottom of the container and ensure it is thoroughly mixed and colour is uniform white. Tint can be added as required.
Tape up any areas before application and remove whilst the epoxy is still wet. Apply a prime coat using a low nap, lint free roller, diluting the SV50 with 10% water. Allow approx 2-3hrs to cure. Apply 1 – 2 additional coats allowing product to cure between coats. If product is to be used as a full coloured coating, then an additional two coats will be required after priming.
Once mixed approximately 45-60 minutes @ 25°C
Approximately 8m² per litre, depending on surface texture.
Drying times have been calculated @ 20°C
48 Hours for foot traffic.
