This primer is specifically designed for interior and exterior masonry and plaster surfaces. It is not recommended for use on wood.

You should wait a minimum of 16 hours to recoat, with a maximum drying time before recoating of 24 hours. Ensure the surface is dry to the touch (approximately 8 hours) before applying a topcoat.

The primer provides a surface coverage of approximately 9 square meters per litre.

No, for health and safety reasons related to all solvent-based paints, spray application is not recommended. It is designed for brush application only.

After use, remove as much paint as possible from your brushes and then clean them thoroughly with a suitable brush cleaner.

Yes, it is particularly suitable for fresh plaster surfaces that may contain alkalis, helping to seal them before decoration.

The Volatile Organic Compounds (VOC) content is 350 g/l, which falls into the 'High' labelling system category (25-50%).

Ensure the surface was properly prepared, clean, dry, and free from dust, grease, or loose paint. For new surfaces, confirm they are fully dry and have not been painted over too soon.

A second coat of primer may be required for particularly stubborn or extensive stains. Ensure the first coat was applied evenly and allowed to dry completely.

This could indicate inadequate ventilation or application in excessively humid conditions. Ensure good airflow and check that the minimum drying time has been met. If the problem persists, apply a very thin second coat or consult technical support.

Ensure the primer is thoroughly stirred. Apply using smooth, even strokes. Avoid over-brushing. Consider using a higher quality brush suitable for solvent-based paints.
