Mortar and cementitious slurry are essential adhesives used in the process of laying floor tiles that binds tiles to the substrate. Mortar, a mixture of cement, sand, and water, provides a durable and level surface for tiles, while cementitious slurry acts as a thin, smooth layer that fills gaps and enhances tile adhesion. These materials ensure proper alignment and provide a strong base for tiling applications. It is important to select the right product as per project requirements. RAZON Engineering is a leading manufacturer of construction chemicals offering a range of mortars and additives. This company has earned a reputation for its exceptional manufacturing of construction chemicals with a focus on high quality. Their products are known for consistently meeting industry standards, delivering reliability and effectiveness to construction projects.
Discussed below are companies two different products Master Mortar MM-TRU & TG-135 used for floor tiling applications.
RAZON Master Mortar-MM TRU: Advanced Bedding Mortar for Floor Tiling
The scarcity of high-quality sand and challenges with homogeneous cement-sand mixes led to the development of RAZON MM-TRU. It is ready-to-use mortar designed for floor bedding, ensuring an extended open leveling time of up to 6 hours, coupled with excellent workability and mortar strength. It stands out for its unique formulation that prevents premature stiffening, allowing for prolonged leveling without the need for re-tempering with water. This simplifies the process, enabling seamless and efficient flat leveling before tile installation.
Advantages of MM-TRU:
- Minimal water requirement enhances mortar density.
- Homogeneous dispersion of cement eliminates dry mixing, ensuring consistent quality.
- No retempering of mortar needed.
- Extended working time of up to 6 hours, even during summers.
- Enhances compressive, tensile bond adhesion, and flexural strength compared to conventional mortars.
- Promotes wet compaction and dry density of SSD mortars.
- Reduced permeability in cured mortar.
- Eliminates issues like mortar flocculation, lumps, and weak bonding seen in conventional m-sand mortars.
- Improved leveling and finish for bedding mortars.
- Reduced risk of sagging and hollow sound post-tile placement.
MM-TRU conforms to IS 2250-1981 (reaffirmed 2010) for Masonry Mortars and IS 10262-2009 for Concrete Mix Design Guidelines.

Applications and method of use
Master Mortar MM-TRU is an excellent choice for floor tiling. It’s a ready-to-use mortar that replaces traditional cement and sand bedding mortars. It’s particularly suitable for floor bedding (machan) instead of cement and sand mortars. It offers great impermeability and is self-curing.
For optimal results in floor tiling:
- Clean and wet the floor that needs tiling.
- Create a cement slurry with a 1:1 ratio of cement to water, and apply it to the cleaned floor.
- Pour MM-TRU onto the floor in a heap and add water (4 liters per 40 kg of MM-TRU).
- Mix the depot/heap with water to create the mortar (avoid dry mortar followed by water spraying).
- Level the mortar as usual.
- Enhance the cement slurry with Razon TG-135, a powder additive that improves bonding.
- Spread the enhanced cement slurry over the MM-TRU bedding mortar.
MM TRU is designed for workability without needing additional water, ensuring a strong and durable cement sand matrix. It shows better bond strength compared to conventional mortars.
MM-TRU has a plastic density of approx 1450 kg per m3, and thus for 45 mm thickness 65 kgs of MM-TRU is consumed in 1 sq m area.

RAZON TG-135: Cementitious Slurry Powder Additive for Superior Bonding & Strength in Tile Installation.
TG-135 is a specialized formulation designed for the tiling industry, commonly used after spreading bedding mortar. A cement slurry is prepared and applied over the mortar before placing tiles. Incorrect slurry consistency can lead to poor adhesion, loose tiles, and hollowness.
- Improves cement slurry consistency.
- Enhances bond strength.
- Increases tackiness.
- Provides a cohesive, non-bleeding slurry.
- Ensures slurry fills gaps in bedding mortar.
- Reduces cement shrinkage.
- Prevents calcite leaching marks at tile joints.
- Enables seamless, impermeable, waterproof tile laying.
- Enhances tack for vertical tiling.
- Offers self-curing properties, eliminating post-work water curing.
Following results were obtained by preparing cementitious slurry as a bond coat placed between bedding mortar (machan) and tile, for floor tiling application using 50 kg Ordinary Portland Cement of 53 Grade, 40 litres of water and 5 kg of Razon TG-135 mixed by mechanical stirrer.

Method of use
The product can be used as a bedding mortar to obtain a firm, non sag and dense bedding mortar. Refer Technical Data Sheet of MM-TRU above for best results in floor tiling.
To prepare cement slurry for floor tiling:
- Add 30-40 liters of clean water to a vessel.
- Gradually add 50 kg of cement while mixing with a mechanical stirrer.
- Mix until uniform consistency is achieved.
- Add 5 kg of Razon TG-135 and continue mixing.
- Apply this slurry on the bedding mortar and lay tiles.
Avoid puncturing or hacking the mortar with a trowel when TG-135 is used.
For wall tiling, add 9-10 kg of TG-135 per 50 kg of cement for a paste-like consistency. Apply this paste on both the wall surface and tile surface using a notched trowel.
Tile grouting with cementitious grouts can be done after 24 hours. For epoxy grouts, allow 5-7 days for complete setting of bedding mortar and binder.
Use Razon Tile Joint Sealer or Razon TJS-EPB epoxy Tile Grout for best results.
