  • Unique silicone based water repellent.
  • Most paints (except cement-based) can be applied over Diggers RainCoat.
  • Prolongs the substrate’s life by preventing moisture penetration.
  • 10 year working life (dependant on conditions).
  • Coverage per litre:

    3m² – Concrete blocks, soft bricks and sandstone
    2m² – Thermalite


1.Ensure the surface is dry and free from dust and grease. Always spot test a small area first as the solvent in Diggers Raincoat may soften some oil-based paints.
2.Diggers Raincoat can be applied by brush or low-pressure spray – do not use atomising sprays. Flood the surface liberally as a penetration of at least 3mm is required. A fluid run down of 150–200mm is a good
indication of correct flooding. Start at the bottom and finish at the top.
3.Curing takes 24 hours. One liberal coating is adequate except on porous surfaces when a second, lighter
coat after 2 hours will ensure complete water resistance. Diggers RainCoat is extremely difficult to remove
from glass after the resin has cured.
4.Clean up with Diggers Mineral Turpentine or Diggers White Spirits.
