Problem Solver - Chalky wall surface
Other Problems
Chalky surfaces occur when a paint film breaks down, usually through exposure to excess moisture.
Preparation
Remove chalky residue. Wash the surface thoroughly using clean water and a mild detergent, working with a stiff brush to remove all loose and powdery material. Rinse well and allow the surface to dry completely.
If mould or mildew is present, this should be treated and removed prior to priming.
Basecoat
Once the surface is clean and all chalk has been removed, the surface must be sealed to stabilise it.
Specifically designed to penetrate and bind chalky, porous, or friable internal surfaces. Provides a sound base for subsequent coatings.
