Technical Data & Application

Surface Preparation
All surfaces should be clean, dry and free from grease. Remove any loose or flaking paint. Rub down bare timber and glossy surfaces with a fine waterproof abrasive paper. Avoid inhalation of dust & other substances when priming any surface.

Stir well before use and apply by brush or roller to either the wooden or metal surface. Apply a liberal coat of Johnstone's 6 Year Life Exterior Undercoat to the surface and paint in one smooth motion in one direction to achieve the best results.

Drying time

Depending on the nature & porosity of the surface, allow 16 to 24 hours drying time between coats under normal conditions.

  • Touch dry: Within 14 Hours
  • Completely dry: Within 24 Hours

    Remove as much product as possible from application equipment before cleaning. Clean all equipment immediately after use white spirit or turpentine substitute and rinse thoroughly to remove all paint from applicators.

    Coverage Guide
    750ml of Johnstone's 6 Year Life Exterior Undercoat will cover approximately 9m² depending on the nature & porosity of the surface.

    Replace lid onto the tin firmly and store in cool dry conditions between + 5°C and +25°C. Storage outside these conditions will dramatically reduce shelf life and may affect the product itself.
