Quick Answer: What is ActivCoat Exterior Primer used for?

Birla White ActivCoat Exterior Primer (20L) is a white cement-based liquid primer made to create a paint-ready base coat on exterior plaster/putty surfaces—improving adhesion, boosting opacity/whiteness, and helping the exterior topcoat look more even and longer lasting.

Manufacturer: Birla White (UltraTech Cement Limited – Birla White Unit)

Product: ActivCoat Exterior Primer (White Cement-Based Liquid Primer)

Pack Size: 20 Litre Bucket

Best For: Exterior plaster / putty-finished walls before exterior paint

Key Benefits for Exterior Painting

  • Stronger Paint Bond: Improves adhesion between wall surface and exterior topcoat.
  • Better Whiteness & Opacity: Supports truer paint colour and reduces patchiness.
  • Exterior-Ready Base Coat: Helps the finish look more uniform across large wall areas.
  • White Cement Compatibility: Suited for cementitious substrates like plaster, putty and concrete.
  • Professional Finish: Helps improve overall topcoat appearance and consistency.

Product Description

Exterior walls go through harsh cycles—sun heat, rain splash, dust and humidity. A good primer is what helps the finishing paint coat perform better on the surface. Birla White ActivCoat Exterior Primer provides a clean, bright base so your exterior paint can deliver improved coverage, better colour consistency and stronger surface bonding.

  • Type: White cement-based liquid exterior wall primer
  • Suitable Substrates: Exterior plaster, putty-finished walls, concrete and masonry surfaces
  • Application Method: Brush / roller / spray (as per site practice and dilution guidance)

FAQs

1) Is ActivCoat Exterior Primer cement-based?

Yes—this is a white cement-based liquid primer designed for exterior cementitious wall surfaces.

2) Can I apply exterior paint directly without primer?

You can, but primer generally improves adhesion, helps reduce patchy finish, and supports a more uniform final coat—especially on new plaster/putty.

3) Where should I avoid using this primer?

Avoid application on wet/damp walls or dusty/chalky surfaces without proper cleaning and preparation. Always follow on-pack instructions for surface suitability.

4) Is this a finishing coat?

No. It’s an undercoat/primer to prepare the surface before exterior paint.
