Keep stone wet while grinding — dry silica dust causes silicosis.
Never skip grit steps — each stage removes scratches from the previous.
Wear safety glasses even when wet grinding — slurry splashes at high speed.

⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
