Efflorescence
Westminster Stone cannot be held responsible for efflorescence, a naturally occurring phenomenon inherent in all highly cementitious products; this may temporarily affect the colour or tone, but will not affect the structural properties, performance or durability of the product. Efflorescence may manifest itself in the form of a deposit or an apparent fading of colour either in patches, runs, or covering the surface. The effects will gradually disappear with time, usage and once natural weathering takes over.
