Plastering trowel Celma PRBt 390S 710W 390 mm — stainless blade, ergonomic handle

Plastering trowel Celma PRBt 390S 710W 390 mm is a handheld finishing tool intended for applying, spreading and smoothing plaster, render and skim coats. The tool has a 390 mm stainless steel blade and an ergonomic handle designed to improve grip and control during interior and exterior plastering, skim coating and final finishing tasks. Its construction balances blade rigidity with user comfort to assist in creating even surfaces and consistent textures.

Advantages

The stainless steel blade resists corrosion and maintains a flat working edge for consistent smoothing. The 390 mm width covers a practical surface area for efficient material distribution while still allowing precise control. An ergonomic handle reduces hand fatigue and improves maneuverability when working on walls and ceilings. The overall design supports reliable finishing and easier maintenance compared with non-stainless or poorly balanced tools.

Suitable for

• Applying and smoothing plaster and cement-based renders
• Skim coating to achieve a uniform surface
• Finishing and leveling interior and exterior walls
• Repairing small surface imperfections and joint areas

Key specifications

• Blade material: stainless steel
• Blade width: 390 mm
• Tool type: plastering trowel / finishing trowel
• Handle: ergonomic design for improved grip and control
• Intended use: plastering, render application, skim coating, finishing

How to use

Prepare the substrate according to the plaster or render manufacturer’s instructions. Load the trowel with the appropriate amount of plaster or render and apply to the surface using even strokes. Use the full 390 mm blade width for broad, flat areas and shorter strokes or angled positions for corners and edges. Keep the blade clean during use to maintain a straight working edge and periodically check the handle connection for stability. After application, finish smoothing with light, overlapping passes until the desired texture is achieved.

Usage recommendations

For best results, use compatible plaster and render materials and maintain the stainless steel blade by rinsing and drying after each use to prevent buildup. When working on large surfaces, alternate hand positions to reduce fatigue and perform routine inspection of the blade edge to ensure even finishes.
