All surfaces should be clean, dry and free from grease. Remove any loose or flaking paint. Rub down sound glossy surfaces with fine waterproof abrasive paper and rinse thoroughly to provide a key. Avoid the inhalation of dust. Wear a suitable face mask if dry sanding. Prime bare surfaces with an appropriate Johnstone’s primer prior to using Johnstone’s Hardwearing Undercoat. Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead.
Ensure maximum ventilation during application and drying.
Not recommended for interior use on large surface areas, or in confined spaces.
Stir well before use and apply by brush. For best results load the brush. Apply liberally and evenly for a smooth finish, avoid overspreading. Under normal conditions allow 16-24 hours before applying a second coat if required. Do not apply when air or surface temperature is below 10 C or in damp conditions. Do not apply over polystyrene surfaces.
Replace lid firmly after use. Remove as much product as possible from application equipment before cleaning. Clean all equipment immediately after use in White Spirit or Turpentine Substitute.
