Polymer Modified Grout In Lucknow

Polymer Modified Grout (PMG) is a type of grout that contains polymer additives to improve its properties compared to conventional cement-based grout. These polymers can be in the form of liquid latex or redispersible powders. PMG is commonly used in tile installations, especially in areas requiring enhanced performance such as high-traffic zones, wet areas, or exterior applications.

🔧 Composition

Polymer modified grout typically contains:

Portland cement: The main binding material.

Sand or other fillers: To add volume and strength.

Polymers: Latex (e.g., acrylic, styrene-butadiene) or redispersible polymer powders.

Additives: Such as water-retention agents, colorants, and antifungal agents.

✅ Key Features and Benefits

Feature Benefit

Improved Flexibility Better resistance to cracking and movement (important for substrates like wood or exterior installations).

Reduced Water Absorption More resistant to staining, mold, and mildew. Suitable for wet areas like showers or swimming pools.

Higher Bond Strength Better adhesion to tile edges and substrate.

Color Retention More uniform and long-lasting color.

Durability Withstands thermal and mechanical stresses better than unmodified grout.

Shrinkage Control Lower shrinkage during curing helps prevent cracks and gaps.

📌 Types

Polymer modified grouts are available in two main forms:

Sanded PMG: For wider joints (typically 1/8 inch or more).

Unsanded PMG: For narrower joints (typically less than 1/8 inch), used on polished stone or glass tiles to avoid scratching.

🏗️ Applications

Bathrooms and kitchens

Wet rooms and shower enclosures

Commercial kitchens and swimming pools

Exterior cladding or paving

Underfloor heating installations

⚠️ Installation Notes

Mixing: Follow the manufacturer's water-to-powder ratio. Too much water or additives can weaken the grout.

Cleaning: Wipe tiles with a damp sponge soon after application to avoid haze.

Curing: Avoid premature exposure to water or traffic; follow curing times (usually 24–72 hours).

Sealing: Some PMGs are dense enough to resist stains without sealing, but sealing may still be recommended in certain conditions.
