Application

For waterproofing and protecting concrete and masonry structures which exhibit cracking and where further movement is expected. Typical applications include the sealing of water tanks, waterproofing of exposed or buried roofs, and use as a crack isolation membrane on concrete floors or screeds. It is also ideal for embedding reinforcing tape to form a flexible waterproof joint sealing system.

Description

Two component, cementitious modified, polymer-rich coating with excellent adhesion to prepared concrete and masonry substrates. When mixed it exhibits a good degree of thixotropy to enable ease of application by brush or spray techniques to give an even finish with no sagging, even in vertical situations. It hydrates to form a durable, highly alkaline, permanently elastomeric coating which not only protects the concrete or other substrates from water penetration and carbon dioxide diffusion, but also accommodates movement in cracks. It is non-hazardous and ideally suited for application inconfined spaces.

Features/ Benefits:

  • Pre-packaged materials only requiring mixing on site.
  • Brush, trowel or spray applied, normally in two coats.
  • Tough, flexible coating which maintains its elastomeric properties even under immersed conditions to accommodate movement in cracks.
  • Good abrasion and very high resistance to freeze/ thaw cycles and de-icing salts.
  • Excellent adhesion to sound prepared concrete and masonry substrates as well as steel.
  • Dense matrix offers low permeability to water even at 10 bar pressure, and very high diffusion resistance to carbon dioxide gas.
  • A 2 mm coat provides the equivalent to 135 mm of good quality concrete cover.
  • Can be applied to damp substrates in temperatures down to 5°C.

Priming:

Epoprime AC should be used on floors and other horizontal areas, including localized cracks and movement joints where reinforcing tape is to be embedded.

Reinforcement:

Over expansion joints and other critical movement areas, Hydroseal RX may require reinforcing with Hydroband 2000 elastomeric, waterproof tape.
