Turns out that not all scouring pads are equal. I switched to 3M from unbranded, without stopping to test, and ripped up three panes of glass. Bad day. On the other hand, process optimised to:
- clear large debris with wet rag
- wipe down with (covalent solvent + newspapers)
- razors as necessary
- also scouring paste (Cif) has been pretty safe so far, but has become redundant...
I guess we should have done more research before embarking on window cleaning. Ah well, the undirect nature of this project. Here's some useful info.
- pour thinner over surface, in a fashion that allows it to spread before evaporating
- scrub with steel brush
- dry with newspaper
- scrapers/razors as necessary
TIL: to prevent cracked cement surfaces, cement + water finish must be applied before underlying mortar is dry. (~1-3 hours)Screw sizes:

0. Approach floor.
1. Use blade to dig up troughs between beams (25 ft x 41 troughs).
2. Use vacuum cleaner to remove debris.
3. Mask edges of troughs.
4. Apply silicone in troughs.
5. Use finger to squish out excess silicone.
6. Remove masking.
At least the scope of work is somewhat predictable. For a while. :)
