Hydroseal RX

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 in confined spaces.

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.

Features and 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.
• Oxygen diffusion: 1.054 x 10ˆ-16 m/sec.
