Using high pressure on the wrong Darwin surface causes permanent damage. Knowing the difference before booking any pressure washing service Darwin is the most important decision a homeowner makes.
High pressure washing at 1,500 to 3,000 PSI is appropriate for concrete driveways, paver paths, pool surrounds, and hard surfaces that withstand significant water impact force. On these surfaces, high pressure flushes embedded red dust, oil, algae, and biological debris out of the porous surface material effectively and safely.
Soft washing at 100 to 800 PSI with biodegradable specialist cleaning solution is the correct method for roof tiles, painted or rendered external walls, soffits, eaves, fascia boards, and timber decking. These surfaces are damaged by high pressure roof tiles crack, render strips, paint lifts, and timber splinters under direct high-pressure water impact. Soft washing kills biological growth chemically before rinsing it away gently, producing results that last significantly longer on the same surface type.
Shining Services selects the method based on the surface never defaulting to high pressure because it is faster. Every job starts with surface identification before any equipment is calibrated.
Honest limitation: pressure washing cannot restore paint permanently stained through to the primer layer from red laterite dust left untreated for extended periods. Our technicians identify staining depth during pre-inspection and give an honest outcome assessment before any work begins.
