Product data

The provided data is typical for factory produced products, subject to slight variation depending on colour. All data is valid for mixed paint. Gloss description: According to Jotun Performance Coatings' definition.

Film thickness per coat

Typical recommended specification range

Dry film thickness 200 - 400 μm
Wet film thickness 210 - 420 μm
Theoretical spreading rate 4.8 - 2.4 m²/l

Spreading rate depends on film thickness applied, type of texture, surface porosity, imperfections, temperature, wastage during painting etc. Coverage on Non slip aggregate would reduce considerably.

Surface preparation

To secure lasting adhesion to the subsequent product all surfaces shall be clean, dry and free from any contamination.

Surface preparation summary table

Laitance deposits are best removed by Planetary diamond disc grinder or by captive blasting followed by vacuum cleaning to remove dust debris. For old concrete, Jotun technical team should visit the site and appropriate surface preparation methodology should be recommended and that is to be followed.

Application

Application methods


The product can be applied by

Brush: Use a stiff nylon brush. Recommended to paint corners and edges.
Roller: Recommended.

To avoid air bubbles, it is very important to pierce the coating with a spiked roller when desired film thickness is achieved. Conditions during application : The temperature of the substrate should be minimum 10 °C and at least 3 °C above the dew point of the air, measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure proper drying. The moisture content in the substrate should not exceed 4 % (by weight). The coating should not be exposed to oil, chemicals or mechanical stress until fully cured. This product should not be applied on to the surfaces which are known to, or likely to suffer from, rising dampness, potential osmosis problems or have a relative humidity greater than 80% as measured in accordance with BS 8203 Appendix A.

Product mixing ratio (by volume)

Jotafloor Coating Comp A 2 part(s)

Dry to over coat, minimum: The recommended shortest time before the next coat can be applied. Dry to over coat, maximum, atmospheric: The longest time allowed before the next coat can be applied.

Dried/cured for service: Minimum time before the coating can be permanently exposed to the intended environment/medium.
