The Słowik LN64 floor leveling straightedge, model 86154, is a 150 cm long hand tool designed to smooth and check the flatness of floor screeds and other horizontal surfaces. Made to serve as a rigid reference edge, this straightedge helps distribute and remove excess cement, mortar or levelling compound, enabling installers to achieve an even plane during manual spreading and finishing operations.
Advantages
The straightedge provides a stable, rigid edge that resists bending during use and maintains a consistent reference for surface plane control. Its 150 cm length covers a practical working width for most room sections, reducing the number of passes required. The tool is suitable for use with cement-based screeds, mortars and self-levelling compounds, and is compatible with manual spreading techniques. Designed for on-site durability, the straightedge simplifies alignment and helps speed up the process of achieving a level floor.
Suitable for
- Manual spreading and levelling of cement screeds
- Smoothing mortar and floor levelling compounds
- Checking and controlling floor flatness during installation
- Removal of excess material to establish an even plane
Key specifications
- Length: 150 cm
- Type: floor leveling straightedge for manual use
- Intended materials: cement, mortar and levelling compounds
- Primary function: smoothing, distributing and checking surface flatness
- Usage: on horizontal floor surfaces and screeds
How to use
Place the straightedge on the surface and use a forward-and-back motion to distribute and remove excess material, maintaining consistent contact with the reference plane. Work from high points toward low points to draw material into depressions and then scrape off surplus. For best results, combine the straightedge with a prior rough screed and follow the levelling compound manufacturer’s instructions for mixing and open time. Periodically check the straightedge edge for wear and ensure it sits flat on the surface while operating.
Usage recommendations
Use the straightedge in conjunction with appropriate personal protective equipment and ensure the substrate is prepared and primed as recommended for the levelling material. Store the tool in a dry place to prevent corrosion and inspect for straightness before each use.
