6 Inch Drywall Sander Pad | 6-Hole Hook & Loop Backing Plate | For Bosch GEX 150

This 6-inch orbital sander backing pad is a direct replacement for Bosch GEX 150 series sanders. It works well for smoothing surfaces. Its 6-hole pattern and strong hook-and-loop face bring back your tool's performance for good, secure sanding on large areas. Features and Benefits - 6-inch, 6-hole setup - Made specifically for Bosch GEX 150, GEX 150AC, and GEX 150 Turbo models for proper dust collection. - Strong hook-and-loop face - Connects sanding discs securely, keeping them from moving or coming off at high speeds. - Balanced medium-density pad - Reduces vibration for more comfortable use and offers enough give for curves while staying firm on flat work. - Direct screw-on fit - You can change your old, worn pad in minutes, so your sander has little downtime. Applications - Large Surface Finishing - The 6-inch size covers more area, speeding up jobs like sanding tabletops, doors, and panels. - Drywall Smoothing - When used with a dust extractor, it helps make a smooth surface on drywall joints before priming. - Auto Body Preparation - Works as a DA sander backing pad for bigger jobs like stripping paint from a hood or leveling large areas of filler. The Risks (Why pros usually avoid it) Using a random orbital sander, such as one compatible with the Bosch GEX 150, for drywall finishing is generally avoided by professionals. The aggressive action of a random orbital sander can quickly remove too much material, creating depressions or swirl marks that are difficult to hide under paint. The high speed and random motion, while effective for wood, can easily tear the delicate paper facing of drywall, leading to "fuzzing" and a poor finish. This makes achieving a smooth, consistent surface challenging for even experienced users. When it Actually Makes Sense While not ideal, there are specific situations where an electric sander, like a palm sander or random orbital sander, can be considered for drywall. It might be used for initial levelling of very proud joint compound, especially on larger areas where manual sanding would be excessively time-consuming. It can also be effective for sanding down patches of heavily textured plaster or old paint before re-skimming. Always start with a very fine grit, such as 220 grit, to minimise the risk of damage. Best Practices If You Use One If you do use a 6-inch drywall sander pad with a random orbital sander, careful technique is crucial. Always use the finest grit sandpaper available, starting with 220 grit. Keep the sander moving constantly across the surface to avoid dwelling in one spot and creating depressions. Use light pressure, letting the tool do the work. If your sander has variable speed, use the lowest setting. Regularly check the surface for swirl marks or damage to the drywall paper. The Big Risks & How to Avoid Them The primary risks are creating swirl marks and damaging the drywall paper. Swirl marks become very visible under paint, requiring additional work to fix. To avoid them, use the finest grit possible (220 grit or higher) and maintain constant movement. Damaging the drywall paper, or "fuzzing," happens when too much pressure or an aggressive grit (like 100 grit or 150 grit) tears the paper facing. This creates an uneven, fuzzy texture that is difficult to smooth. Destroying the Drywall Paper ("Fuzzing") "Fuzzing" occurs when the abrasive action of the sander tears the paper face of the drywall, lifting fibres and creating a rough, fuzzy surface. This is a common issue when using electric sanders on drywall, especially with coarser grits like 100 grit or 150 grit, or when excessive pressure is applied. Once the paper is fuzzed, it is very difficult to achieve a smooth finish. To avoid this, always use a very fine grit (220 grit is a good starting point), light pressure, and a consistent, feathering motion.
