Application

Remove from the surfaces any contaminants that might be detrimental to surface preparation and painting. Also remove water-soluble salts by using appropriate methods. The surfaces are prepared according to the different materials as follows:

OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities that might be detrimental to the application of paint (e.g. grease and salts) should be removed. The surfaces must be dry and clean. Old, painted surfaces that have exceeded the maximum overcoating time of Teknos 3393 should be roughened as well. Damaged parts should be prepared in accordance with the requirements of the substrate and the maintenance coating. Ensure the prepared surface will not get dirty or damp before treatment.

Clear varnishes with special effects must be stirred thoroughly before mixing with hardener. The base and hardener are mixed together and stirred mechanically thoroughly before application down to the bottom of the tin. Mechanically stir for at least 5 minutes. Inadequate stirring or wrong mixing ratio results in imperfect curing and impaired film properties. Ready paint is to be used within the pot-life. After this the mixture is unfit for use.

For the application it is recommended to use airless spray (nozzle 0.011-0.013") or conventional spray. Conventional spray gives the best result. The components are not to be thinned separately. The hardener of the paint and the ready paint mixture contain isocyanates. In poorly ventilated areas and especially when using spray application we recommend the use of a fresh air mask. In short or temporary work a mask with combined filter A2-P2 can be used. In this case eyes and face are to be protected. The hardener-can must be opened with caution, as pressure may develop in the can during storage.
