The Festool 205418 Planex LHS 2 Sander Interface Pad is an interface sander backing pad accessory for Festool PLANEX long-reach sanders. This is a sander interface pad designed for connecting the sanding pad to the abrasive for wall and ceiling sanding. Model number 205418. If you are running a compatible PLANEX setup and want the correct buffer layer between the sanding pad and abrasive, this is the part that keeps the system working the way Festool intended.

What this pad does is straightforward but important. It connects the ST-D220/48-LHS 2 225 sanding pad to the proper abrasive, which helps deliver consistent sanding results on broad drywall and surface-prep work. On the job, that means better contact across the surface and a more controlled feel when you are working overhead or reaching across large walls.

Festool built this accessory around its StickFix hook-and-loop system, so abrasive changes stay quick and secure. That is a real time-saver when you are stepping through grits during drywall finishing, skim coat prep, or surface refinement. Instead of wasting time fighting worn-out attachment methods, you can swap discs and keep moving.

Installation is simple. The interface pad mounts to the sanding pad with eight plastic screws, and Festool specifically notes that you do not need a screwdriver to install them. A coin or a second screw is enough to turn them in. That is the kind of practical detail that matters when you are changing parts in the middle of a job and do not want to dig through the van for another tool.

Size matters here too. This pad is 9" (225 mm), in diameter, matching the large-format sanding surface used on compatible PLANEX long-reach sanders. That large working area is what makes the PLANEX platform such a strong choice for drywall and surface prep, and this accessory is built specifically to support that system rather than act as a one-size-fits-all substitute.

Compatibility is the main thing to pay attention to before you buy. This interface pad is suitable for the PLANEX LHS 2 225 EQ(I) and PLANEX LHS 2-M 225 EQ long-reach sanders. Festool also states that it is not suitable for the older PLANEX LHS 225 EQ or PLANEX LHS-E 225 EQ. It also must be used in conjunction with the ST-D220/48-LHS 2 225 sanding pad, so this is not a standalone universal backing pad.

Who should buy it? Anyone already running a compatible Festool PLANEX drywall sander and needing the correct interface layer for abrasive mounting and sanding performance. It makes the most sense for drywall finishers, remodelers, painters doing prep, and contractors who depend on the PLANEX platform for large surface sanding and want the right Festool accessory instead of guessing with a workaround.
