Floor leveling straightedge Słowik LN64 250 cm — model 86254, 250 cm length

The Słowik LN64 floor leveling straightedge, model 86254, 250 cm length is a long aluminum tool designed to provide a reliable reference edge for levelling and smoothing floor screeds and concrete surfaces. Built for use in manual or mechanical screeding, this straightedge helps achieve an even plane across large floor areas and supports accurate preparation before tiling, finishing or applying floor coverings.

Advantages

The straightedge features a lightweight yet rigid aluminum profile that balances portability with resistance to bending during use. Its 250 cm working length allows operators to cover broad spans with fewer passes, improving efficiency on medium to large jobsites. The tool's straight profile provides a consistent guide for screeding tools and hand trowels, contributing to uniform flatness and reducing the need for excessive rework.

Suitable for

• Levelling cement and sand screeds over medium to large floor areas
• Smoothing fresh concrete surfaces prior to finishing
• Preparing subfloors for tile, vinyl, laminate or engineered wood installation
• General renovation and contractor works requiring a straight reference edge

Key specifications

• Material: aluminum profile offering a balance of light weight and stiffness
• Working length: 250 cm for extended coverage per pass
• Profile shape: straight edge suitable for manual and mechanical screeding
• Intended use: levelling and smoothing of floor screeds and fresh concrete

How to use

Position the straightedge on prepared screed or concrete between established reference points or rails. For manual screeding, pull or push the straightedge along the surface while maintaining contact with guide rails or screed rails to remove excess material and obtain a flat plane. For mechanical applications, use the straightedge as a datum or check tool to verify flatness after machine passes. Regularly check the straightedge for straightness and clean any adhered material before storage to preserve its accuracy.

Usage recommendations

Use with appropriate guide rails or leveling bars on longer spans to prevent sagging; avoid using the straightedge as a pry bar or lever. Store horizontally on a flat surface or hang to prevent warping. Clean off cement residues promptly to maintain the aluminum profile and prolong service life.
