Materials & methods we'd use here
Most Downderry properties we treat have painted render and pebbledash walls and a Cornish slate and concrete tile roof. That changes a few of the choices we'd make.
- Method
Sodium hypochlorite mixed to a strength suitable for painted render and pebbledash - never neat on coastal village stock
- Method
Quaternary ammonium surfactant added so biocide clings to your painted render and pebbledash elevation in Downderry
- Method
Painted brickwork treated by dwell-and-rinse only on coastal village terraces - no rotary
- Method
Lime render handled with a half-strength mix and a longer dwell — important on older Downderry stock
