• Surface dry in 2 - 4 hours depending on temperature and porosity
• The second coat may then be applied 4 - 6 hours after the first coat has dried

Preparation

• The roof area must be thoroughly cleaned, prior to application of the coating in order to remove accumulated dirt, debris, bird faeces, moss, lichen, fungus and all other detritus materials and free from laitance before application
• The area to be coated must be pressure washed to remove all substrate contaminates
• Care must be taken not to damage the roof structure, whilst pressure washing
• Replace any damaged tiles prior to coating

Application of Britannia Fungicidal Wash:

• The fungicidal wash solution is best applied by brush, to allow a thorough substrate penetration
• The fungicidal wash solution should be applied at a rate of 10-20 square metres per litre
• After application the roof should be allowed to dry completely and then inspected to ensure a uniform substrate coverage and that there is no water trapped in joints between the tiles

Application

• Stir well before use
• Please follow the Coverage rates shown in Spreading Rate Section
• All tile coating work should be carried out in dry conditions and without the forecast of precipitation or frost, within 6 hours of applying the coat
• No coating should be carried out in times of condensation conditions or when the relative humidity exceeds 90%
• No coating should be carried out when the substrate temperature is below 5°C or above 35°C
• The maximum permissible moisture content of the substrate is 21%
• If possible do not apply the coating when the roof tiles are very hot, in order that premature surface drying and poor substrate wetting does not occur
• When dry after a minimum of 4-6 hours drying the second coat of material may be applied

Note. During the summer months there is a possibility of paint skinning from warm weather/transportation (top of inside lid and rim). We recommend that the paint is pre-filtered on site through a course filter to remove skins before spraying.

Cleaning

• Clean all equipment immediately with water after use

Shelf Life & Storage

• Up to 12 months if stored correctly in an unopened container
• Store above 5°C

Precautions

• Keep out of reach of children
• In case of contact with eyes wash immediately with plenty of water
• Remove splashes from skin with soap and water or a recognised hand cleaner
• Protect from freezing
• Do not apply paint if there is a risk of heavy rain or frost
• Do not use near fishponds
