Light Weight Block Joint Mortar
Redwop Chemicals offers high-quality lightweight block joint mortar designed for strong, durable bonding between blocks in construction projects. Our block joint mortar provides excellent workability and is specifically engineered to enhance the strength and longevity of lightweight block structures. Ideal for both residential and commercial buildings, it ensures smooth application and reliable results.
Redwop Light Weight Block Joint Mortar is a ready-to-use, polymer-enhanced, lightweight cementitious mortar designed for precision jointing of AAC, CLC, concrete hollow blocks, and brickwork. Its smooth paste consistency enables pillow-thin joint finish (~3–4 mm), significantly reducing mortar usage while delivering higher build accuracy and structural integrity in both load-bearing and non-load-bearing walls.
Ideal Applications
Designed for use with AAC blocks, CLC blocks, concrete hollow blocks, fly-ash bricks, and conventional clay bricks, Redwop Mortar is ideal for residential, commercial, and institutional buildings. It excels in rapid masonry wall erection, internal partitions, exterior facades, and high-rise blocks—where precision, speed, insulation, and finish matter most.
Application Guide
Clean surfaces and gently pre-moisten blocks to building damp. Add approximately 6–6.5 L of clean water per 25 kg bag and mix for 3–4 minutes using a drill mixer to a smooth, paste consistency. Joints should be 3–4 mm thick—spread uniformly with a trowel or roller. The mortar’s pot life ranges from 90–120 min; apply within this window. No external curing needed: the polymer blend enables self-curing, though a light mist is advisable in hot, dry weather to maintain hydration.
Key Features & Benefits
This mortar self-cures to provide strong tensile adhesion (≥ 0.8 MPa) and compressive strength (> 5 MPa within 28 days) while minimizing shrinkage and surface cracks. The low-density blend of lightweight fillers and polymers enhances thermal insulation and moisture resistance, improving indoor comfort and wall durability. Lightweight jointing ensures easier, faster application with less lug weight, making it ideal for modern construction practices.
FAQ's
