To retain the original appearance of limestone, the use of a limestone sealant should be applied to the exposed areas.
Limestone Sealant, 'Waterepel' provides a water-resistant finish without affecting the natural colour of limestone.
Limestone should be free of dust and dry prior to sealing.
A low-pressure garden spray or similar device is ideal. Apply from the top of the stone and work down the wall.
For areas close to windows and doors the sealant can be applied using a paint brush.
