Intermediate Crack-Bridging Filler and Coating (EN1504-2)

Overview

Monodex ICB is an elastomeric, intermediate, water-based crack-bridging filler and coating which is designed for use where enhanced crack-bridging properties are required. It is capable of bridging existing cracks up to 1mm and also acts as a filler for pores, cavities and blowholes.

Supplied as a ready-mixed paste for ease of use, it is highly cost-effective and can be applied straight onto the substrate as no primers are required. Monodex ICB also has excellent anti-carbonation properties, and therefore offers enhanced performance and even greater anti-carbonation protection when used in conjunction with Monodex Smooth, Monodex Textured, Monodex Ultra or Monodex UVC.

As Monodex ICB is water-based, it has minimal VOC levels and releases ultra-low odour during application, making it ideal for use in sensitive or enclosed environments. Typical applications include outdoor exposed concrete surfaces with a high risk of cracking, commercial buildings, residential housing, hotels, offices and industrial buildings and fast-track construction or refurbishment projects.

Advantages

  • Versatile, trowel applied or diluted with water for roller and spray application. Mixed with sand as a mortar.
  • Water-based and low odour, curing rapidly without the release of hazardous solvents.
  • Active encapsulated in-film biocide inhibits the growth of mould, mildew and lichens.
  • Fills cracks, pores, cavities and blowholes. High solids content minimises shrinkage in deeper applications.
  • Economic material requiring no substrate or inter-layer priming. Can be applied to existing paint finishes.
  • Excellent crack-bridging properties even at temperatures as low as -20ºC.
  • Able to bridge cracks and joints up to 1mm.
  • High diffusion resistance to carbon dioxide, enhancing the anti-carbonation performance.
  • Low water vapour diffusion resistance allows damp substrates to breathe and dry out without blistering.
