Frequently Asked Questions

Most anti-mould additives are concentrated, with 100ml typically treating up to 5 litres of paint. For a standard room, you may need 1-2 bottles depending on wall size and number of coats. Glitter additives vary by desired density, so start with smaller amounts.
Most anti-mould concentrates, like Dryzone, are compatible with emulsion, vinyl, silk, and matt paints. Always check the manufacturer’s instructions to ensure compatibility with your specific paint brand and finish to avoid altering the texture or drying time.
High-quality glitter additives generally do not compromise durability if mixed thoroughly. However, excessive amounts can affect the paint film's integrity. Use the recommended ratio and apply a clear topcoat if extra protection is needed for high-traffic areas.
