Protector Block Jointing Mortar from RVM DRY MIX™ is a high-performance, polymer-modified thin-bed adhesive formulated for AAC blocks, CLC blocks, concrete blocks, fly ash bricks, porotherm blocks, and wire-cut clay bricks. Blended with OPC cement, graded fine aggregates, and advanced additives, it delivers excellent adhesion with uniform 3–4 mm joints that ensure cleaner, stronger, and crack-resistant masonry walls.
Designed for modern construction practices, it offers smooth workability, reduced material usage, and faster application compared to traditional sand–cement mortars. The innovative self-curing technology provides optimal hydration and bonding without additional water curing, saving valuable time and labor on site. Its thin-bed application improves wall alignment, surface finish, and overall masonry speed, making it ideal for residential, commercial, and high-rise projects.
A single 40 kg bag of Protector BJM covers approximately 1 CBM of AAC blocks at the recommended thickness, ensuring economical consumption with minimal wastage. Manufactured in ISO-certified, PLC-controlled facilities, each batch maintains premium quality, reliable bonding strength, and long-term durability — making Protector the trusted choice for precision masonry work.
Provides excellent adhesion between AAC, CLC, and fly ash blocks, ensuring durable, crack-free joints that enhance wall stability.
Reduces material consumption significantly while improving alignment accuracy and delivering cleaner masonry finishes.
Eliminates the need for external water curing, enabling faster construction and efficient on-site workflow.
Mixes into a lump-free, creamy mortar that spreads easily and speeds up block laying operations.
Minimizes shrinkage cracks and ensures long-term integrity of walls in both internal and external applications.
A single 40 kg bag covers approximately 1 CBM of AAC blocks, reducing overall project costs and wastage.
Ideal for lightweight AAC block construction in residential and commercial projects.
Ensures precise alignment and strong adhesion for modern alternative block systems.
Provides reliable bonding for internal and external load-bearing or partition walls.
Suitable for premium blockwork requiring thin joints and smooth finishing.
Enhances wall stability and reduces structural load due to its efficient thin-bed application.
Supplied in a 40 kg laminated BOPP bag for longer shelf life and easy handling.
Up to 12 months when stored in sealed condition under dry storage, ensuring consistent performance.
Keep in a cool, dry place away from moisture and direct sunlight. Store bags on pallets to prevent lumping.
Contains cement, prolonged exposure may cause skin or eye irritation. Use gloves and protective eyewear.
Wear a dust mask while mixing or handling the dry powder to avoid respiratory discomfort.
If the material comes in contact with eyes, rinse with plenty of clean water and seek medical attention if irritation persists.
