283-322 is suitable for priming all types of MDF and wood substrates for interior use. It can be used to give closed grain finishes.

Substrate should be sanded with 120, 150 or 180 grit sandpaper prior to finishing. Difficult or oily substrates may require the use of 401-033 Isolante sealer prior to priming to ensure maximum adhesion.

Agitate before use, and while adding hardener and solvent as per mixing ratio. To ensure product consistency, the mixed material should be agitated at all times. When cured, P.U. Primer White must be sanded to be recoated within eight hours of sanding.
The relative humidity in the application and drying rooms should never exceed 75%. Viscosity on the catalyzed material should be monitored regularly to maintain a consistent appearance.
