## Long description

The Kubala Sponge Rubber Hard Float 140x280 mm (model KB 0397) is a handheld finishing tool intended for applying, leveling and refining plaster, cement mortars and renders on walls and floors. The tool combines a firm rubber working face with a sponge backing that helps control moisture during finishing operations. Its 140 × 280 mm rectangular size provides a compact work area suitable for detailed smoothing and edge work where larger floats are impractical.
Advantages
The hard rubber face provides even pressure distribution for a uniform surface texture while resisting wear during repeated use. The sponge backing helps retain and release water in a controlled way to aid in smoothing and avoid over-wetting the material. The compact dimensions and handheld format offer precise handling for corners, small patches and trimming around fixtures. The combination of materials reduces the need for frequent re-wetting and allows for consistent finishing results with plaster and cement-based mortars.
Suitable for
 Applying and finishing plaster on interior walls and small exterior patches
 Leveling and texturing cement mortars on floors and screeds
 Refining render edges and smoothing around openings and fixtures
 Touch-up work and small-area repairs
Key specifications
 Working face material: hard rubber
 Backing material: sponge for moisture control
 Dimensions: 140 × 280 mm
 Tool type: handheld finishing float
How to use
Moisten the sponge backing lightly before use to achieve controlled water release during smoothing. Hold the float with a firm grip and apply even pressure while moving the tool across the plaster or mortar surface in broad, overlapping strokes. For edges and corners, use the short side of the float and apply lighter pressure to avoid gouging. Clean the rubber face and sponge after use with water and a mild brush to remove residual material, then allow to dry before storage.
Usage recommendations
Use the Kubala sponge rubber hard float during the final stages of application when material has begun to set but is still workable. Avoid excessive water on the backing to prevent weakening the mortar. Inspect the rubber face for cuts or deep abrasions before each use; replace the tool if the working surface is compromised to maintain consistent finish quality.
