The Festool 577252 PLANEX LHS Interface Pad IP-D220-LHS 2 225-SW is an interface sander backing pad made for Festool PLANEX long-reach drywall sanders. This is a sanding pad accessory designed for sanding very soft compounds and fillers with better surface control. Model Number: 577252. If you are finish sanding drywall compound, soft skim coats, or similar delicate surfaces, this pad helps reduce how hard the sanding head bears down on the work.

What makes this accessory matter is simple: soft material can get chewed up fast when a large drywall sander applies too much pressure. Festool designed this pad to dampen the application pressure from the PLANEX LHS 2 225 head. In real use, that means less risk of gouging soft compound, less chance of leaving swirl-heavy low spots, and a better shot at getting the wall ready for paint with fewer corrections.

The pad installs with a hook-and-loop connection onto the screwed-on PLANEX abrasive pad, then your abrasive mounts to the interface pad the same way. That setup keeps it easy to add only when the job calls for it. On harder material you may not need the extra cushion. On very soft material, though, this is the kind of accessory that can save time because it helps you avoid sanding damage that has to be patched and redone.

At 8-1/2 in. (225 mm) in diameter, it matches the sanding head size used by compatible PLANEX machines. That full-size coverage is important on walls and ceilings because it preserves the wide sanding footprint that makes a long-reach drywall sander efficient in the first place. You keep the reach and broad contact area of the PLANEX system, but with a softer interface between the machine and the surface.

Festool also recommends pairing this interface pad with Granat Net abrasives. That recommendation is worth paying attention to if dust control matters on your job. Net abrasives are a practical fit for wall and ceiling sanding because they support better extraction across the pad surface, which helps keep the work area cleaner and the abrasive cutting more consistently.

Compatibility matters here. This accessory is made for the PLANEX LHS 2 225 EQ(I) and PLANEX LHS 2-M 225 EQ long-reach sanders. It is not suitable for the earlier PLANEX LHS 225 EQ or PLANEX LHS-E 225 EQ. That is a critical buying detail, because interface pads are not universal across all PLANEX generations.

Who should buy it? Drywall finishers, painters, remodelers, and contractors using the newer PLANEX 2 platform on soft compounds. If your work includes final passes on skim coat, lightweight filler, or fast-drying compounds that mark up easily, this accessory earns its keep. If you run an older PLANEX model, skip this one and match the pad to your machine instead.

Small Accessory, Big Difference on Soft Finish Work

The Festool 577252 PLANEX LHS Interface Pad IP-D220-LHS 2 225-SW is the kind of add-on that makes sense the second you hit a soft wall compound that wants to get scarred up by a full-size drywall sander.

• Who it's for: Pros using the newer PLANEX 2 sanders for drywall finishing, skim coats, and delicate filler work.
• Why it stands out: It solves a real problem by softening the sanding action without giving up the big 225 mm working area.
• Worth knowing: This is not a universal PLANEX pad. Check your machine model before you order, because it does not fit older PLANEX versions.

• What is this interface pad used for? It is used to reduce sanding pressure when working on very soft compounds, fillers, and other delicate wall or ceiling surfaces.
• Which sanders does it fit? It fits the Festool PLANEX LHS 2 225 EQ(I) and PLANEX LHS 2-M 225 EQ long-reach sanders.
• Will it fit older PLANEX sanders? No. It is not suitable for the PLANEX LHS 225 EQ or the PLANEX LHS-E 225 EQ.
• What size is the pad? The pad diameter is 8-1/2 inches, or 225 mm.
