💡 What handy tricks do guys use to patch wall openings without calling big contractors?
Workshops teach pressing high grade clay straight into gaps for fast results that stand up to daily wear.
- Scrape rust and dust off surfaces so the clay grips tight
- Roll the material into cords and jam them deep inside chases
- Flatten the outside rim so wind and rain bounce right off
- Swap out brittle patches every few years to keep loops sealed
