Plastering Straightedge PRO trapezoidal 120 cm 204-12

Plastering Straightedge PRO trapezoidal 120 cm 204-12 is a rigid leveling rule designed to assist with smoothing and flattening plaster and render on interior and exterior walls. The 120 cm length and trapezoidal profile provide a stable, straight reference for striking off excess material and achieving an even surface. Constructed for professional masons and DIY users, this tool balances stiffness and handling to maintain long straight lines during plasterwork.

Advantages

The trapezoidal cross-section increases torsional rigidity, reducing flex and ensuring a straight strike even across larger spans. Its 120 cm working length covers substantial surface area while remaining manageable for single-person use. The profile is optimized to sit flat against the wall, helping to minimize surface undulations and deliver uniform results. The tool is suitable for repeated use on both interior and exterior coatings and is compatible with common plaster and render materials.

Suitable for

• Leveling and striking off plaster and cement render on walls
• Smoothing skim coats and finishing base coats
• Preparing flat surfaces before painting or tiling
• Interior and exterior wall renovation and repair tasks

Key specifications

• Length: 120 cm working edge
• Cross-section: trapezoidal profile for increased rigidity
• Primary use: plastering and rendering leveling rule
• Suitable surfaces: interior and exterior walls
• Handling: designed for manual operation by one person

How to use

Position the straightedge on the wet plaster or render and draw it along the surface with steady pressure to remove excess material and create a flat plane. For best results, work from a guide or screed points set to the desired level, moving the straightedge in overlapping passes to maintain continuity. Clean the working edge regularly during use to avoid buildup that can affect flatness. After initial leveling, refine the surface with appropriate float or finishing tools once the material reaches the recommended working time.

Usage recommendations

Use the straightedge in combination with properly spaced guides or screeds for larger areas, and keep the tool clean of cured material. Store dry and handle to avoid dents or deformation of the working edge to preserve straightness.
