Ok, so I have a sloping garage floor and I'd like to stripe the walls. The slope is probably about 2% back to front, or low to high. Common sense tells me to measure from the floor along the wall at various points corner to corner. The tricky part is at the lowest point (back corner) there is a 4" buffer before the sheet rock begins. The high corner is flush to the floor. How do I measure properly? Do I add the 4" along the way (rise over run)? I can't measure from the ceiling because its flat.
