Berger Aquashield 90

A silane based water repellent treatment for porous mineral substrates that penetrates deep into the substrate to form a clear hydrophobic layer that repels water and moisture.

Berger Aquashield 90 is a water repellent/anti-carbonation coating for use on bare and porous mineral substrates such as concrete and bricks. It has excellent water repellent characteristics and penetration power. It forms a breathable coating, allowing concrete to breathe. It is effective even when applied to damp substrates. It also has good alkaline resistance.

Surface preparation

  • New concrete should be left for at least 21 days to cure before coating.
  • The surface to be coated must be clean and free from all loose extraneous materials such as loose paint, dust, etc. Perform high pressure water wash external walls to remove all loose materials.
  • If fungus or algae is present, first treat with Berger Fungicidal Wash and leave for 24 hours.
  • Then, thoroughly rinse and wash or scrape away all the fungus.
  • If grease is present, clean using a mild detergent or solvent and rinse thoroughly to ensure complete removal of the grease, detergent and solvent.
  • This product only works when applied directly to the substrate. As such, when refurbishing old substrates, all existing coatings must be removed to bare substrate before application of Aquashield.

Application procedure

Stir contents of the can thoroughly before use. Thinning is not required. Apply freely to sufficiently flood the surface. After the first coat has penetrated and is just about to dry off, apply a second coat.
