A HIGH PRESSURE WASHER CONSISTS OF THE FOLLOWING:
A petrol or electricity driven motor.
A trigger style high pressure cleaning gun with various nozzles.
Industrial standard high quality pressure hose for a consistent flow of water.
High pressure hose pipe.
There are currently a number of High Pressure machines on the market and it is important to utilise a suitable machine for a particular operation. Some plug in power units is limited to 120 bars which is in adequate for most roofs and driveways. Those require a pressure of up to 200 bars.
PREPARATION OF AREA TO BE CLEANED
Preparation is important both from a safety as well as a safeguarding your equipment or assets.
Before a high pressure operation at homes it is important to clear the area of any furniture, portable braai, cars and loose carpets before spraying a roof. Taking cognisance of the wind direction is important as a high pressure spraying operation could damage sensitive plants if proper care is not taken.
It is good practice to inform your neighbours about your roof cleaning to ensure that no washing is out near the area to be sprayed.
SAFETY AND EQUIPMENT
Non slip boots should be used and where required a harness should be worn especially when working on high or asbestos roofs as Asbestos are very slippery.
Ladders should be placed up wind on the dry side where no spraying is taking place as a wet roof with Algae is a disaster waiting to happen. Workers should be constantly reminded of safety and safety procedures during spraying.h
