About Mixing

2. Precision Mixing & Formulation

Using automated machinery and controlled conditions, we blend the ingredients in the right proportions to ensure uniformity and stability.

Standard Exterior Primer Formula:

30–35% Acrylic Emulsion

25–30% Weatherproof Extenders

8–10% Titanium Dioxide & Opacifiers

2–5% Anti-Fungal & Algaecide Additives

Remainder: Water, Dispersants, and Preservatives

This formula delivers:

Excellent UV protection

Anti-peel surface preparation

Strong paint adhesion

Long-lasting topcoat performance

3. Advanced Blending & Homogenization

We use industrial high-speed dispersers and inline homogenizers to:

  • Ensure particle uniformity
  • Maintain consistent viscosity
  • Improve overall weatherproofing ability

4. pH and Rheology Control

Each batch is tested to ensure:

  • pH between 8.5–9.5
  • Viscosity: 90–110 KU for optimal brush/roller/spray application
  • Excellent workability on cement plaster, concrete, and masonry

5. Filtration & Quality Testing

The final product undergoes multi-layer filtration and rigorous quality tests:

  • Adhesion & Bond Strength Test
  • Weather Resistance Test (QUV)
  • Anti-Fungal & Algae Resistance Test
  • Water Repellency & Breathability
  • Coverage & Hiding Power Test

Only compliant batches are cleared for packing.

6. Packing with Weather-Proof Assurance

Packed in robust, leak-proof containers:

  • 1 Litre | 4 Litres | 10 Litres | 20 Litres

We use UV-resistant, tamper-proof packaging to preserve quality during storage and transport.
