Initial assessment
Substrate type, age, condition, contamination, moisture. Tells us what method, what tooling, what timeline.
SURFACE PREP · SYDNEY METRO
Surface Preparation The Foundation of Every Floor
Professional substrate preparation for coatings, polished concrete, and floor systems. Grinding, crack repair, contaminant removal, moisture testing — ready-to-coat handover with documented profile.
WHAT IS SURFACE PREP
Everything That Happens
Before The Coating Goes On.
Surface preparation is the complete process of getting a substrate ready to receive a new coating, sealer, or floor system. It includes diamond grinding, shot blasting (for heavy industrial prep), crack repair, joint sealing, contaminant removal, moisture testing, and profile assessment. Without proper surface prep, even the best floor coating will fail.
WHAT'S INCLUDED
Six Steps To A Ready-To-Coat Slab
Mechanical preparation
Diamond grinding, shot blasting, or scarifying depending on the system going down and the substrate condition.
Crack & joint repair
Epoxy crack filler, patch and anchor work, joint sealants. Cracks treated before any coating goes on.
Contaminant removal
Oil/grease cleaning, salt contamination treatment, efflorescence removal. The slab leaves prep chemically clean.
Moisture testing
For slabs where vapour transmission could compromise the coating — tested with hygrometer or calcium-chloride method.
Final inspection
Confirming CSP profile matches the specified coating system. Documented handover with photos and notes.
WHO IT'S FOR
Hand It Over Ready
If you're a builder, property manager, or tradie planning to apply your own coating, polished concrete contractor, tiler, or vinyl installer — we can prep the substrate professionally and hand it over ready for your finish. Includes a documented profile assessment so you know exactly what you're working with.
STANDARDS
Industry standards we work to
AS 3958.1 (Tiles — substrate prep requirements). ICRI CSP guidelines (Concrete Surface Profile 1–9). AS 3740 (where waterproofing follows). Profile is delivered to the standard appropriate for the system going on top.
