Application Guidelines

FAQs

1) What makes Activcoat Exterior Primer different from interior primer?

Activcoat Exterior Primer is formulated for outdoor conditions with enhanced weather resistance, UV protection, and durability against rain, humidity, and temperature fluctuations. Interior primer lacks these protective features. Always use exterior-specific primer for outdoor applications.

2) Can I use Activcoat Exterior Primer on interior walls?

Yes, exterior primer works on interior walls but is more expensive than interior-specific primers. For cost-effectiveness, use Birla White Activcoat Interior Primer indoors and reserve exterior primer for outdoor applications where weather resistance is essential.

3) Do I need to use Birla White putty with Activcoat Exterior Primer?

No, Activcoat Exterior Primer works with all putty brands (cement-based and waterproof). While formulated for Birla White putty, it provides excellent adhesion and sealing on any properly prepared exterior putty surface.

4) How long should I wait before painting after primer application?

Wait for complete drying as per product label instructions (typically 4-6 hours minimum). In humid conditions or thick applications, allow longer drying time. Ensure primer is fully dry before applying exterior paint for optimal adhesion.

5) Can I apply exterior primer in rainy season?

Not recommended. Apply primer only when weather is dry and no rain is expected for 24-48 hours. Rain on fresh primer washes it away and causes uneven coverage. Plan exterior painting during dry season for best results.

6) Why is my exterior paint fading or chalking?

Common causes: (1) Skipping primer or using low-quality primer, (2) Using interior paint outdoors, (3) Poor surface preparation, (4) Excessive UV exposure without UV-resistant topcoat. Always use quality exterior primer and UV-resistant exterior paint.

7) How much primer do I need for my exterior project?

Coverage depends on surface condition and dilution ratio. For typical exterior walls, estimate 120-150 sqft per litre. The 20L bucket covers approximately 2400-3000 sqft. Add 10-15% extra for wastage and rough surfaces.
