Flexible sanding sponge KLINGSPOR SK500 98x68x25 mm grit 150

The KLINGSPOR SK500 flexible sanding sponge, size 98 x 68 x 25 mm with abrasive grit 150, is designed for manual sanding and finishing of wood, painted surfaces, plaster and other common substrates. Its elastic foam backing adapts to contoured surfaces, edges and profiles to provide even abrasion and improved contact on irregular shapes. The medium 150 grit is suitable for smoothing surfaces and preparing them for subsequent painting, sealing or varnishing.

Advantages

The flexible foam core ensures consistent pressure distribution and reduces the risk of creating flat spots on curved surfaces. Abrasive grains are fixed uniformly on the sponge for steady material removal and longer life compared with untreated sponges. Compact dimensions make the sponge easy to handle for manual work and reach into corners and tight areas. The product is suitable for wet or dry sanding depending on the application and the substrate.

Suitable for

• Smoothing wooden components and profiles
• Finishing painted or varnished surfaces
• Removing minor irregularities and surface imperfections in plaster
• Preparation of surfaces before painting, sealing or gluing
• Detail sanding on curved or contoured parts

Key specifications

• Dimensions: 98 x 68 x 25 mm
• Abrasive grit: 150 (medium)
• Flexible foam backing for conforming to shapes and edges
• Suitable for manual wet or dry sanding
• Designed for wood, paint, plaster and similar substrates

How to use

Hold the sanding sponge with moderate pressure and move it along the surface following the grain on wood or in even strokes across paint and plaster. For curved or profiled areas, let the foam backing adapt to the shape and avoid excessive force that could alter the profile. For finer results, finish with a higher grit; for faster material removal, use coarser abrasives. If wet sanding, rinse the sponge periodically to remove debris and allow the abrasive to stay effective.

Usage recommendations

Use light to moderate pressure and inspect the surface frequently to avoid over-sanding. After sanding, clean the surface of dust before applying paint, varnish or sealant. Replace the sponge when abrasive performance decreases or the foam backing is damaged.
