TRUBUILD CFP 525

TRUBUILD CFP-525 is a cement-based polymer modified powder material for filling cracks in plastered surface. It is composed of cement, select aggregates, polymer & additives which requires on site addition of water only. Cracks filled with Trubuild CFP-525 enhance the subsequent paintings quality and life.

Application
Applications
  • To fill static cracks of 3 to 5 mm.
  • To level undulation on un plastered or plaster celling’s and walls prior to painting.
  • To provide smooth finish to brick, stone, and concrete
  • For crack filling – Fill the mixed paste into the crack by spatula or putty knife blade. Fill excess material and tool it by putty knife blade pressing against crack so that air voids get filled. By wet finger tool the surface of material in to a concave nature by pressing against joint edges
  • For Surface levelling – The mixed smooth paste should be applied by painter blade on the dampened wall or ceiling. The material should be applied at the desired thickness in bottom- to -up fashion to avoid blade marks. For multiple coat applications the previous coat should be allowed to cure for minimum 6 hrs. The subsequent coat should be at the right angle to the previous coat
Application
Advantages
  • Adhesion - Strong adhesion to common building substrates
  • Easy to use - It is a do it yourself product & requires only onsite addition of water
  • Requires only addition of water on - site at the time of usages.
  • As surface leveller before painting it reduces paint consumption and increases the life of the paint making it economical
How to use
How to use
  • Ensure the joints edges to be neat and sound. Make sure that surface is clean & free from standing water. The surface should be free of loose debris
  • Contaminations of oil, grease or bitumen should be completely cleaned
  • In normal conditions Trubuild CFP-525 does not require a primer. However, in critical areas water based acrylic or SBR based primer can be used depending on the severity of surface and application
  • Mixing ratio of Trubuild CFP-525 to water varies with respect to area of application
  • For filling deep holes and cracks-reduce the water quantity to get a thicker pasty consistency
  • The final mixed product would be of dough consistency paste. In case further soft consistency is required, measured quantity of water can be used
