Cemprotec Elastic is a two component, thixotropic, cementitious modified, polymer rich waterproofing coating. It cures to form a durable, highly alkaline, permanently elastomeric coating which protects concrete and other mineral substrates from water penetration and carbon dioxide diffusion, but also accommodates movement in cracks

Typical applications include the sealing of water tanks, waterproofing of exposed, buried or green roofs, and use as a crack isolation membrane on concrete floors or screeds.

Usage & Highlights

• Pre-packaged material only requiring mixing on site.
• Brush, trowel or spray applied, normally in two coats. Flooring applications are a one coat operation.
• Tough, flexible coating which maintains its elastomeric
• properties even under immersed conditions to accommodate movement in cracks.
• Excellent adhesion to sound prepared concrete and masonry substrates as well as steel.
• Ideal for use in confined spaces non toxic when cured.

Surface Preperation

The areas to be treated must be free from all unsound material, dust, oil, grease, corrosion by-products and organic growth. Smooth surfaces should be roughened, all loose material and surface laitance removed and reinforcement cleaned to bright steel using wet grit blasting techniques or equivalent approved methods.

Mixing

Cemprotec Elastic is supplied as a two pack, Part A liquid and Part B powder. The two components MUST NOT be split. All of Part and all of Part B MUST be mixed. Shake Part A (liquid) and pour into a suitable mixing vessel. Slowly add the Part B (powder) and mix for a minimum of 5 minutes until homogenous, without any lumps. Mixing should be carried out using a slow-speed drill and paddle designed to entrap as little air as possible.

Please Note: It is vital to the success of the application that these instructions are strictly adhered to. Flexcrete cannot be held responsible for any product failures due to incorrect mixing.

Cleaning and Storage

Tools should be cleaned with water immediately after use.

Materials can be stored for 24 months in dry, frost free conditions with unopened bags at 20°C.
