Application Guidelines

Why Buy from HomeRun?

1) What makes Birla White ActivCoat different from other primers?

ActivCoat is white cement-based, so it is highly compatible with cementitious surfaces. It offers high opacity (160–200 sq ft per litre on a single coat), needs no pre-wetting, and is GreenPro certified. It is formulated for Birla White putty but works with all putty brands.

2) Do I need to wet the wall before applying ActivCoat?

No. Unlike traditional cement-based primers, ActivCoat needs no pre-wetting. Just make sure the surface is clean and dry, which saves time and simplifies the painting process.

3) How much water should I add to dilute ActivCoat?

Dilute 1:1 by volume with clean water — 1 part primer to 1 part water. This is a concentrated cement-based formulation and should be thinned 1:1 under all standard application conditions, including porous surfaces, to keep its flow and coverage.

4) Can I use ActivCoat Interior Primer on exterior walls?

Not recommended. It is designed for interior walls. For exterior walls, use Birla White ActivCoat Exterior Primer, which offers weather resistance and UV protection for outdoor conditions.

5) How many coats do I need, and why is my coverage lower than 160–200 sq ft per litre?

160–200 sq ft per litre is the single-coat figure for smooth, previously painted walls or high-quality putty work. For raw, newly plastered or highly porous surfaces, the brand strongly recommends two coats, which gives 90–110 sq ft per litre and ensures uniform opacity and blocking. Allow 10–15% extra for wastage.

6) Can I use ActivCoat with non-Birla White putty?

Yes. It works with all putty brands, cement-based and acrylic, and gives good adhesion and sealing on any properly prepared putty surface.
