Polystyrene foam grater Kubala 160 x 380 mm

Polystyrene foam grater Kubala 160 x 380 mm is a handheld finishing tool designed for shaping, trimming and smoothing expanded polystyrene (EPS) panels. The 160 x 380 mm working surface provides a broad contact area that helps remove excess foam, level edges and produce an even texture on insulation boards, architectural models and decorative polystyrene elements. The tool is lightweight and intended for manual use during construction, renovation or hobby projects where controlled material removal and a consistent finish are required.

Advantages

The Kubala polystyrene foam grater combines a wide working surface with a compact handheld design to deliver controlled trimming and smoothing of EPS panels. Its flat, abrasive surface ensures even material removal across the entire contact area, reducing the need for additional sanding. The tool is simple to use, requires no power source and is easy to handle during repetitive passes along edges or flat areas. Designed for practical on-site use, it supports precise finishing while minimising material waste.

Suitable for

• Trimming and leveling expanded polystyrene insulation boards
• Finishing edges and surfaces of architectural models and prototypes
• Preparing EPS panels for adhesive application in façade and insulation systems
• DIY and craft projects involving polystyrene shaping and smoothing

Key specifications

• Working surface dimensions: 160 x 380 mm
• Type: Handheld polystyrene foam grater for manual use
• Primary material compatibility: Expanded polystyrene (EPS)
• Function: Material removal, smoothing and edge finishing
• Ergonomics: Lightweight, handheld format for repetitive passes

How to use

Hold the grater with a firm, even grip and position the working surface against the EPS panel at a shallow angle. Move the tool in steady, even strokes along the panel surface or edge, applying consistent pressure to remove excess foam and achieve the desired thickness and smoothness. For best results, make multiple light passes rather than a single heavy cut. Check the surface frequently and adjust angle or pressure to refine edges and maintain an even finish. Clean the working surface of accumulated particles periodically to preserve cutting efficiency.

Usage recommendations

Use the Kubala polystyrene foam grater in a well-ventilated area and wear appropriate personal protective equipment such as safety glasses and a dust mask to avoid inhalation of fine particles. For large surfaces or extended use, combine manual grating with coarse sanding or a mechanical EPS cutter as needed. Store the tool in a dry place and remove debris from the working surface after each use to prolong service life.
