MasterCrete 5140

Cementitious Polymer Modified Thin Layer Fairing Mortar

How Does MasterCrete 5140 Work?​

MasterCrete 5140 is a concrete grey, ready to use, polymer modified mortar formulated with hydraulic binders and graded quartz sands. It is designed as a high performance fairing coat for application in thin layers up to 3 mm to correct surface imperfections and achieve a uniform fair faced finish on concrete or masonry substrates. The mortar provides excellent adhesion, workability and surface durability, and can be overcoated with protective or decorative systems from the MasterShield range or left exposed.

Recommended Uses:

• Suitable for levelling uneven surfaces, filling honeycombs and pin holes. It can be used as a topping (render) of up to 3mm thick to face up masonry.

• Thin resurfacing of damaged concrete surfaces, such as in rain damaged slabs and for use in non-moving crack repairs.

What Are the Unique Features of MasterCrete 5140?

The formulation contains no chlorides or other soluble salts that may contribute to corrosion of embedded reinforcement or surface blooming. MasterCrete 5140 is compatible with other mortars in the MasterCrete range for multi layer repair systems. When applied under suitable substrate and environmental conditions, it does not require a separate primer or curing membrane.
