Used for: Crack bridging, substrate priming, + masking crazing.
Monodex ICB is a single component, water-based, thixotropic compound with dual purpose as a substrate primer and elastomeric crack bridging medium for concrete, render and other masonry substrates.
Designed for use on surfaces which exhibit cracking or which have a high risk of cracks forming. It is also effective in masking existing crazing in painted surfaces prior to protection and decoration with specialist membranes.
It is capable of bridging existing cracks up to 1mm and acts as a filler for pores, cavities, and blowholes. It also enhibits mould, mildew, & lichen, has excellent anti-carbonation properties, and allows damp substrates to breathe and dry out without blistering.
Monodex ICB from Flexcrete is an elastomeric primer and crack-bridging compound with enhanced polymeric properties. It is supplied as a ready-mixed paste for ease of use and can be applied directly onto the substrate as no primers are required.
Active encapsulated in-film biocide inhibits the growth of mould, mildew, & lichen while high diffusion resistance to carbon dioxide enhances the anti-carbonation properties of the substrate. Low water vapour diffusion resistance which allows damp substrates to breathe and dry out without blistering.
Water-based formulation makes for a low odour product which cures without the release of hazardous solvents. It is suitable for trowel application undiluted, or spray, brush, & roller application when diluted with water.
Monodex ICB has excellent anti-carbonation properties, minimal VOC levels, and releases ultra-low odour during application. These properties make it ideal for use in sensitive or enclosed environments. It is CE marked in accordance with BS EN 1504-2.

Preparation
The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth. Mechanically remove surface laitance and any soft, sandy or flaking material. Use techniques to achieve the required degree of preparation, such as wet grit or water blasting techniques or equivalent approved methods. Flexcrete Concrete Repair Mortars must be allowed to cure for a minimum of 24 hours. Leave concrete and cementitious screeds or renders for a minimum of 10 days, preferably 28 days.
Equipment
Brushes: Wide, soft nylon or bristle paint brushes.
Trowel or Float: Steel.
Rollers: Medium Pile synthetic cover.
Spray: Airless spray at 2500-3000psi (finish off in one direction).
Substrate Priming
MONODEX ICB is self-priming. Ensure substrate moisture content is less than 20% wood moisture equivalent prior to application.
To seal highly absorbent surfaces, dilute 2 parts with 1 part clean water by weight and apply at a coverage rate of 5m²/l by brush or roller. Application. Ensure complete coverage. Rough or porous surfaces will increase consumption.
Reinforcing Cracks & Joints
MONODEX ICB will accommodate cracks and joints typically up to a width of 1mm. Fill live cracks, construction joints and joints between dissimilar materials to leave a flush finish with the substrate. Allow to dry and lightly sand to remove any prominent edges.
Fill larger static cracks or voids with MONODEX ICB bulked out with sand to a mortar consistency. Use up to 20% by weight of a 0.1-0.3mm clean kiln dried sand and apply by trowel to achieve the desired finish. Allow to harden but not fully cure before sanding to remove any prominent edges.
Note - Extending with sand will affect physical properties.
Coating Application
When used as an intermediate crack-bridging coat, apply by brush, roller or airless spray at the coverage rates below ensuring that a uniform film is achieved and that all blow holes and surface defects have been filled.
To reduce surface texture for roller application, dilute up to 5% with clean water. Dilute up to 10% with water for airless spray application.
Allow to dry for 1-4 hours in ideal conditions until touch dry before applying a second coat.
