Surface preparation

Clean and dry surface. Surface contamination is to be removed by detergents and fresh water cleaning.

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 3ºC 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 correct 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.

Application data

Mixing ratio (volume) Single pack.

Thinner/Cleaner Jotun Thinner No. 2

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. 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

Spontan Varnish 1 - 3 x 35 µm (Dry Film Thickness)

New wood-work should first be prepared with one coat Spontan Varnish thinned 10% with Jotun Thinner No. 2.

Other systems may be specified, depending on area of use
