Surface preparation is key to the longevity of a roof coating. Follow our tips to get the best possible result.
Substrate: Concrete tiles
Note: Not suitable for weathered asbestos slates and fibre cement slates.
Surface Preparation:
Proper surface preparation is crucial to maximum finish performance. The durability of this product can be impaired by an unsound or poorly prepared surface. Surfaces must be clean, dry and sound before painting.
- Treat any fungal growths with Colourtrend Fungicidal Wash as per instructions on packaging.
- Power wash to remove all dirt, grime and loose material. Pressures of 1500-2000psi, preferably with hot water, (steam cleaning), have proven particularly effective. Power washing should be carried out from top to bottom of roof, cleaning each tile with a downward motion, taking care not to disturb the slates which can lead to subsequent leaking of the roof.
