HotBatch is the portable cordless mixer for powdered setting compound. The sealed hopper doses dry powder while you mix — dial in the perfect consistency with no dust cloud, no bucket, and no drill.
Every deposit is counted here, in the open. Money only moves when a gate is hit — that's the deal.
Connecting…
Every drywall pro knows the ritual. We built HotBatch to kill it.
Setting compound is feather-light powder. Pour it, scoop it, breathe it — it goes everywhere except where you want it.
Water, guess the powder, drill + paddle, stop, check, add more, remix. Five minutes of mixing for a patch that takes two minutes to apply.
20-minute mud doesn't wait for your mixing routine. Mix too much and it sets in the pan. Mix too little and you're doing it all again.
Water to the line. Lock the lid. Press MIX. Adjust as it blends. That's the whole thing.
Fill the clear 32 oz cup to the marked water fill line. Load dry powder into the sealed top hopper.
Twist-lock the lid and hit the big MIX button. The low-speed, high-torque cage paddle folds the mud — no blades, no whipped air.
Tap + POWDER to dose dry mix straight into the blend, + WATER for a splash. Adjust consistency without stopping.
Pop the lid, use your mud. The 3-piece wet side — cup, paddle, lid underside — rinses clean in seconds.
This isn't a blender with a new sticker. Every part exists because mixing setting compound demanded it.
Dry compound goes from bag → sealed hopper → wet mix. No open scoop, no powder cloud drifting across the room.
Two thumb buttons meter small dry and water doses mid-mix. Patch mud, bed coat, finish — dial the consistency per task.
Rounded low-speed paddle with contoured silicone edges scrapes the cup clean for a smooth, cream mix. No sharp blades.
High-torque geared drive in a sealed top unit. The base never touches mud — it never needs rinsing.
Only three parts ever touch mud: cup, paddle cartridge, lid underside. Tool-free removal, dishwasher safe, no blind holes for compound to harden in.
Clear measurement markings for repeatable batches. Mix exactly what the patch needs — stop throwing away half-set pans.
HotBatch comes from a licensed GC who's mixed ten thousand buckets of hot mud and hated every one of them. This is the tool he wished existed.
