Surface preparation

Concrete substrates must be fully cured, sound, clean, dry and free from any form of contamination such as laitance, loose particles, oil, grease, curing compounds, shuttering oil, algae growth etc. Recommended pre-treatment methods are light grit blasting or high pressure water jetting (approx' 150 bars). Unsound concrete, blowholes, pinholes and other surface defects should be repaired using approved repair products/systems. The moisture content in the concrete substrate must be = 6% by volume. Please contact your local Jotun Office for more information.

Other surfaces

The coating may be used on other substrates. Please contact your local Jotun office for more information.

Condition during application

The temperature of the substrate should be minimum 10°C and at least 3°C above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure proper drying.

Application methods

Spray Use airless spray

Brush Recommended

Roller Recommended

Filter Check to ensure that filters are clean.

Drying time

Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:

• Good ventilation (Outdoor exposure or free circulation of air)

• Typical film thickness

• One coat on top of inert substrate

1. Recommended data given for recoating with the same generic type of paint.

2. The surface should be dry and free from any contamination prior to application of the subsequent coat.

The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.

Typical paint system

Penguard Clear Sealer 1 -2 x 50 µm (Dry Film Thickness)

Penguard Midcoat 1 x 125 µm (Dry Film Thickness)

Hardtop XP 1 x 50 µm (Dry Film Thickness)

Other systems may be specified, depending on area of use
