STONE ADHESIVE

About STONE ADHESIVE

 91 000 74051 LATICRETE 315 PLUS is a high-performance, single-component, polymer-modified cementitious adhesive designed for bonding ceramic tiles, vitrified tiles, precast terrazzo, and natural stone on both floors and walls. It offers excellent workability and extended open time, making it ideal for professional installations where precision and flexibility are important. The adhesive can be mixed with either clean water or a latex admixture (such as LATICRETE 3701) for enhanced performance and strength.

It works well on a variety of cement-based substratessuch as concrete, concrete masonry, cement plaster, mortar beds, and even existing tile surfaces (after proper surface preparation). LATICRETE 315 PLUS supports thin-bed installation methods and can handle a maximum bed thickness of up to 12 mm. It is available in grey and white variants. 

Key Features & Benefits:

• Easy to Use: Just add water for mixing no multi-part systems or complex preparation required. 

• Extended Open Time: Provides a long pot life (up to ~3 hours) which gives installers more time to adjust tiles and ensures proper setting. 

• Non-Sag: Designed for vertical (wall) applications without sagging, ensuring tiles stay in place perfectly. 

• High Bond Strength: Exceeds the shear bond strength requirements of ANSI A118.4 and meets IS 15477:2019 Type 2 T standards. 

• Flexible & Strong: The polymer-modified formula provides good flexibility and impact resistance; can be fortified with a latex admixture (LATICRETE 3701) for even better performance, especially in exterior or demanding applications. 

• Substrate Compatibility: Bonds to a wide range of surfaces concrete, brick masonry, plaster, mortar beds, existing tiles, etc. 

• Very Economical Coverage: Around 5560 sq ft per 20 kg bag (with ~3 mm bed thickness, using a 6 6 mm notched trowel). 

• Certifications & Standards: Complies with EN / ISO as a C2TE adhesive. 

• Bed Thickness Flexibility: Can be applied up to 12 mm bed depth, giving room for uneven substrates.

Superior Bonding Strength for Stone Applications

Formulated specifically for stone, marble, granite, and concrete, this industrial-grade epoxy adhesive ensures a reliable hold with impressive mechanical properties. The mixture cures within 12-24 hours and features a 30-40 minute pot life at 25C, allowing for ample working time without compromising strength. Its high viscosity guarantees excellent gap filling, while its chemical and weather resistance make it perfect for both indoor and outdoor use.


User-Friendly Application and Mixing

This adhesive is simple to mix and apply, requiring only a 2:1 ratio by weight for optimal results. It is supplied as a paste in convenient packaging sizes (1 kg, 5 kg, 10 kg buckets), and should be applied at a recommended thickness of 1-3 mm. With a mild odor and non-toxic properties upon curing, it offers a safe and efficient option for construction professionals and distributors.
