Acrylic Polymer Coating


Trubuild APC-225 (Acrylic Polymer Coating) is an acrylic polymer-based coating which is used in conjugation with cement as a coating for waterproofing and bonding application.


Trubuild APC-225 is used as protective coating for concrete structures like sunken portion, toilets, balcony, chajja, basement, terrace, and concrete repairs. It can be used for water retaining structures & general concrete repairs. It can be used for Protection of concrete against corrosion, salt attack etc.

  • Economical
  • Can be used in both horizontal & vertical surface
  • Excellent adhesion on various substrates
  • Reduces or prevents salt attack
  • Can be used as waterproofing coating
  • Can be used as bonding agent
How to use
How to use

Surface Preparation


  • The surface should be clean and dried before application. It should be free from dust, unsound material, loose plaster, oil, paint, grease, algae and corrosion deposits. Fill all the cracks up to 5 mm by Trubuild CFP 425 and above by making PMM using Trubuild WPL 333.


Waterproofing Coating


  • Make a slurry of 1:2 ratio of Trubuild APC-225 and cement and apply first coat on concrete surface. Make sure that concrete surface is in SSD condition before application of first coat. After 5 -6 hours of application of first coat, apply second coat of Trubuild APC-225 coating. After application of 2nd coat, allow the system to air cure for 5 to 6 hours. This should be followed by moist curing by sprinkling /spraying of potable water for 24 hours. After moist curing, the surface should be allowed to air cure for 3 to 5 days before covering it with screed and there after lay the protective screed to avoid mechanical damage. Coverage: 1.125kg mix/m²/2coats


Render & Mortars


  • Add 10-15% of Trubuild APC-225 by weight of cement, in a 1:3 cement and sand mortar for repairing of patch work as per the suitability

Handling precautions

Precaution and Limitation


  • Trubuild APC 225 should not be used in isolation of cement
  • Trubuild APC 225 shall be applied to the substrate temp above 10°C to below 40°C
  • Surface should be in SSD condition. Neither apply fully dry surface nor standing water
  • Ensure to provide a protective plaster over the final coat to avoid mechanical damage
  • Avoid coating in intermittent of rain
