how to sand walls methodically
Even with experience and the fantastic Mirka CEROS / Abranet combo, you can get lost sanding a big area of wall. It is usually down to a distraction – someone comes in and starts talking to you, or a lapse in concentration as you think about food or pay day or… Either way, when you run your hand over the surface, confident you sanded every millimetre, you come across bits you missed.
The conventional way to stay methodical is to mark a simple grid of 3 foot squares with a piece of chalk and methodically sand each square, sanding out the chalk marks as you go along the wall.
For me, a quicker and more fluid less chalky hand-staining way is to just get on with sanding! I use the rubber cable on my sander to mark a couple of 3 feet high lines, spaced a comfortable sanding distance apart.
Check in a discreet area that the mark will sand out easily!
If working right to left, I sand out the line to my right as I go and leave the left line intact. With that “grid square” completed, (double check with finger tip quality control) I move along a comfortable distance to the left, mark another 3 feet high line with my cable and sand out the right line, leaving the new left line intact.
I have seen no documentation, but presumably after x number of marks, eventually the rubber coating on the cable will wear away. So keep one step ahead and wrap a sheath protector around the cable and use that as your primary (sacrificial) wall marker.
A very tiny detail, but is intuitive with no extra tools required.
