Preparation
Always ensure the surface to be treated is clean, dry and free from any dust, algae, fungi or moss.

- Allow the previous coat to soak in before applying the next coat, usually 2-6 hours under normal weather conditions
- Recoat within 2-3 days of previous coat
- Apply only in dry conditions, above 5°C and when bad weather is not forecast
- Colour in the can may be different to the final shade when dry
- Avoiding splashing of surrounding plants, brickwork, glass, PVCu, etc. Any splashing should be cleaned up immediately

- If using more than one tin it’s advisable to mix together in a large container or finish in a corner before starting a new can to ensure consistency in colour
