Likfix Anti-sagging Waterproofing Coating




General Description

CANLON brand Likfix is a one component anti-sagging Polyurethane Waterproofing Coating made out of the main materials of isocyanate and polyether polyol, together with various auxiliaies and fillers. Likfix Waterproofing Coating can achieve even thickness after one time spraying on vertical wall. Sprying, brushing and rolling can be adopted as installation methods.

  • Waterproofing to basement, deck, bathroom, balcony, pool, parking lot and non-exposed roof.

  • Waterproofing to special constructions such as granary, civil defense projects and bridges.

  • Exposed color steel roof retrofit.


  • Spray application shall greatly elevate the construction efficiency, while atomization effect can fill the minor defects of the substrate to avoid air bubbles, delivering better waterproof performance .

  • During vertical wall application, anti-sagging property could avoid the quality problems of coating film being "thin at the top and thick at the bottom".  

  • CAS waterborne epoxy resin can be coated on the substrate thinly to improve the bonding strength of polyurethane coating and substrate even in the case of wet or unclean surface. 

  • Strong deformation resistance avoids the phenomenon of the waterproof layer being pulled apart instantly due to the structural crack.

  • Excellent vapor barrier performance,free from common quality problems such as yellowing and mildew.

  • Reliable bonding for subsequent construction, pat some dry,medium or fine sand onto the surface of last uncured coat before pasting ceramic tile or plastering.


Substrate preparation:

The substrate must be clean, smooth, free from floating dust and pond/standing water.

Coating mixing: mix the liquid evenly using mechanical blender.

Brush the Likfix Waterproofing Coating onto substrate using rubberized scrapers; ensure the cured membranes to be equal in thickness.

Generally, two or three coats are required; each coat thickness shall be less than 0.7mm. After the first coat become dry, then the second one can proceed, the previous and next coats must be perpendicular until total thickness reaches required one.

When vertical application is executed, spray some fine sand onto the surface of last coat(within 12 hours before curing) to keep the reliable adhesion between waterproofing membrane and subsequent plastering layer.
