What is 42 Platinum Laticrete Unsanded Cementitious Grout?
42 Platinum Laticrete Unsanded Cementitious Grout 600 Series is a pre-blended, polymer-modified cementitious grout designed specifically for tile and stone installation. The 1 kg packaging (product code 394812) makes it ideal for small to medium-sized projects, repairs, and test applications. This product represents Laticrete's commitment to providing high-performance solutions that meet international standards while being accessible to the Indian market.
The "unsanded" designation is crucial—it means this grout lacks coarse aggregate, making it perfect for narrow grout joints, typically those less than 3mm in width. This characteristic is particularly valuable in modern Indian tile installations where contemporary designs often feature tight, refined grout lines.

Advantages Over Traditional Grout Products
Superior Durability
Traditional unsanded grouts can be brittle and prone to cracking. The 42 Platinum formulation's polymer modification provides elasticity that absorbs stress from building movement and thermal expansion. This is particularly important in India, where buildings often experience significant temperature fluctuations between seasons.
Enhanced Aesthetics
The unsanded composition creates a smooth, refined finish that enhances the appearance of modern tile installations. Unlike sandy grouts that can appear coarse, this product maintains a consistent, professional appearance that appeals to contemporary design preferences.
Easier Application
The fine particle size of unsanded grout makes it easier to apply and clean. Contractors working on projects across Indian cities appreciate the reduced labor intensity and faster project completion times this enables.
Better Water Performance
The polymer modification creates a denser matrix that resists water penetration more effectively than traditional Portland cement grouts. This is crucial in India's varied climate zones, from the monsoon-heavy coastal regions to the dry interior areas.
How to Use 42 Platinum Laticrete Unsanded Cementitious Grout 600 Series
Preparation and Mixing
For the 1 kg package, follow these steps:
Measure the powder: Use the entire 1 kg package
Add water: Typically 250-300 ml of clean water, though this may vary based on desired consistency
Mix thoroughly: Use a mechanical mixer for 3-5 minutes until achieving a smooth, lump-free consistency
Let stand: Allow the mixture to rest for 5-10 minutes before use (slaking period)
Remix briefly: Stir for another minute before application
The exact water ratio depends on environmental conditions—higher humidity may require slightly less water, while drier conditions might require more.
Application Process
The installation process involves several key steps:
Substrate Preparation: Ensure tiles are properly set with appropriate thinset mortar and have cured for at least 24 hours
Joint Cleaning: Remove any debris or excess mortar from grout joints
Grout Application: Use a grout float held at a 45-degree angle, working diagonally across the tile surface
Excess Removal: After initial set (typically 15-20 minutes), use a damp sponge to clean excess grout from tile surfaces
Curing: Keep the installation dry for at least 48-72 hours for optimal strength development
Environmental Considerations
In India's diverse climate zones, temperature and humidity significantly affect curing times. In hot, dry regions like Rajasthan or Gujarat, grout may set faster, requiring quicker application. In humid coastal areas, slower curing times may be necessary. Always adjust your work schedule and techniques based on local weather conditions.
Coverage and Yield Information
The 1 kg package of 42 Platinum provides approximately:
2-4 square meters of coverage for standard 300x300mm tiles with 3-5mm grout joints
1-2 square meters for larger format tiles with wider joints
0.5-1 square meter for small decorative tiles with narrow joints
These estimates assume standard application thickness. Actual coverage varies based on tile size, joint width, and substrate porosity. For projects in Indian cities like Bangalore, Hyderabad, or Pune where modern tile formats are common, calculate your specific needs carefully before ordering.
Cost Considerations in the Indian Market
The 1 kg package of 42 Platinum Laticrete Unsanded Cementitious Grout 600 Series typically costs between ₹400-600 in the Indian market, depending on:
Location: Prices in metro cities like Mumbai, Delhi, and Bangalore may differ from tier-2 cities
Supplier: Direct distributors often offer better rates than retail outlets
Bulk orders: Purchasing multiple packages can reduce per-unit costs
Availability: Specialty products may have limited availability in smaller cities
While premium grouts cost more initially than basic alternatives, the durability and performance benefits often justify the investment, particularly for high-visibility or high-traffic areas.
Common Mistakes to Avoid
Incorrect Water Ratio
Adding too much water creates a weak grout that won't achieve full strength. Too little water makes application difficult. Always start with the recommended ratio and adjust gradually.
Insufficient Curing Time
Exposing grout to water too early, especially in bathrooms, compromises long-term performance. Respect the 48-72 hour curing period, or longer in humid conditions.
Poor Joint Cleaning
Debris in joints prevents proper grout adhesion. Take time to thoroughly clean joints before grouting.
Inadequate Surface Preparation
Tiles must be fully set before grouting. Grouting over incompletely cured thinset leads to grout failure.
Neglecting Climate Factors
India's varied climate means application techniques must adapt. Don't use the same approach in Chennai's humidity as you would in Delhi's dry climate.
Comparing 42 Platinum with Alternatives
When evaluating grout options for Indian projects, consider:
vs. Traditional Unsanded Grouts: 42 Platinum offers superior flexibility and water resistance
vs. Epoxy Grouts: While epoxy provides maximum durability, 42 Platinum offers better workability and lower cost
vs. Sanded Grouts: For joints under 3mm, unsanded options like 42 Platinum are the only appropriate choice
vs. Generic Brands: Laticrete's proven track record and consistent quality justify the premium pricing
Storage and Shelf Life
The 1 kg package should be stored in a cool, dry location away from moisture. Properly stored powder grout typically maintains quality for 12-18 months. In India's hot, humid climate, store in air-conditioned areas when possible. Always check the manufacturing date before purchase, particularly important when sourcing from smaller retailers.
