weberfloor smooth 4150 - Smoothing And Levelling Compound

weberfloor smooth 4150 is designed for fine levelling and preparation of a wide range of internal floor constructions in both new build and refurbishment projects. It is suitable for application over concrete, sand/cement and anhydrite screeds, as well as over suitably prepared existing levelling screeds.

The product is applied as part of bonded floor constructions, where it produces a smooth, level surface to receive common floor finishes such as resilient flooring, tiles, timber and carpet. It is not intended for use in unbonded or floating constructions, nor for applications subject to movement such as directly over underfloor heating systems without an appropriate intermediate levelling screed.

weberfloor smooth 4150 can be installed by both pump (machine) application and hand application, supporting efficient installation across projects of varying scale and complexity.

For bonded applications, correct substrate preparation is essential and will typically require the use of a suitable primer, such as weberfloor 4716, and where necessary a damp proof membrane system to control residual moisture and ensure long-term performance.

As part of a complete flooring system, the use of Weber complementary products—including primers, moisture management solutions and preparation materials—is recommended to optimise adhesion, control substrate conditions and achieve consistent installation performance.
