Surface preparation

 

All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.

 

Coated surfaces

Clean, dry and undamaged compatible primer. 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 0°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 or conventional spray

Brush Recommended for stripe coating and small areas, care must be taken to achieve the specified dry film thickness.

Roller May be used for small areas.

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

 

Substrate temperature	5°C	10°C	23°C	40°C
Surface dry	7 h	5 h	3h	0,5 h
Through dry	24h	12 h	5h	3 h
Cured	21d	14 d	7d	3 d
Dry to recoat, minimum Dry to recoat, maximum 1	24h	12 h	5h	3 h

 

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

2. Early exposure to condensation (high humidity, low temperature) may cause colour and/or gloss variations.

 

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.
