Trowel Kubala KU0804 triangular 200×190 mm – plastering and smoothing tool

The Kubala KU0804 triangular trowel with working dimensions 200×190 mm is a hand tool designed for plastering, smoothing and leveling surfaces in corners and angled areas. Its triangular blade profile provides controlled application of mortar, plaster and repair compounds, allowing precise finishing where flat trowels cannot reach. The tool is intended for use in construction, renovation and small repair jobs that require targeted smoothing and corner treatment.

Advantages

The triangular shape delivers access to narrow corners and angled joints while maintaining even pressure across the blade for consistent material distribution. A compact working size of 200×190 mm balances reach and maneuverability, enabling accurate finishing on tight spots without sacrificing control. The design supports efficient smoothing and leveling of thin layers of plaster or repair compounds and reduces the need for multiple passes.

Suitable for

• Finishing internal corners and angled joints
• Applying and smoothing plaster in confined or detailed areas
• Repairing cracks and small surface defects
• Renovation and small-scale construction tasks

Key specifications

• Working dimensions: 200 × 190 mm
• Blade profile: triangular for corner and angle work
• Primary applications: plastering, smoothing, leveling, repair compounds
• Suitable surfaces: interior walls, corners, joint lines and small repairs

How to use

Prepare the substrate by removing loose material, dust and grease to ensure good adhesion. Load a thin, even amount of mortar, plaster or repair compound onto the triangular blade and apply it to the target area with steady pressure, working from the inside of the corner outward or along the joint as appropriate. Use long, smooth strokes to level the material; adjust angle and pressure to control thickness and finish. After initial set, lightly refine the surface if needed for a uniform result.

Usage recommendations

To prolong tool life and maintain performance, clean the blade after each use with water and a brush before the material hardens, dry it thoroughly and store in a dry place. For best results, use the triangular trowel for finishing and corner-specific tasks rather than bulk plaster distribution.
