Question 1

What preparation is included before coating?

Accepted Answer

Preparation normally includes site inspection, mechanical diamond grinding, removal of weak surface material, edge detailing, crack or defect review, and dust-managed cleanup. The goal is to create the correct concrete profile for primer or coating adhesion, not just make the slab look cleaner.

Question 2

How much does concrete grinding cost in Sydney?

Accepted Answer

Concrete grinding pricing depends on slab condition, coating or glue removal, access, dust controls, and whether the floor is being prepared for epoxy, tile, levelling compound, or polishing. Use the calculator for a budget range, then request a site-specific written quote before locking in the program.

Question 3

Is concrete grinding dusty?

Accepted Answer

We use industrial vacuum extraction systems directly attached to our grinders. Our process is virtually dust-free.

Question 4

Can concrete grinding level uneven floors?

Accepted Answer

Yes. Diamond grinding effectively removes high spots, lippage, and minor unevenness across concrete floors.

Question 5

How long does concrete grinding take?

Accepted Answer

A standard residential garage (40–60sqm) typically takes 4–6 hours for grinding preparation. Larger commercial floors are staged across multiple days. Surface Master Australia schedules grinding and coating as a continuous process where possible to reduce total project time.

Question 6

What equipment is used for concrete grinding?

Accepted Answer

Surface Master Australia uses commercial planetary multi-head diamond grinders for all projects. These machines use rotating satellite heads that deliver consistent CSP 2–4 profiles across the full slab. Industrial HEPA extraction is run in line with all grinding equipment.

Question 7

Can concrete grinding be done in sections?

Accepted Answer

Yes. Large floors and working facilities are regularly ground in sections or stages. Surface Master Australia coordinates staging around your operational schedule. Staged grinding is common in warehouses, factories, and commercial premises.

Question 8

What is a CSP profile for concrete?

Accepted Answer

CSP (Concrete Surface Profile) is an ICRI standardised measure of surface roughness. CSP 1 (smooth) through CSP 10 (very rough). Epoxy systems require CSP 2–4. Planetary grinders achieve this consistently; single-phase hire machines typically achieve only CSP 1–2.

Question 9

How do I know if my floor is ready for epoxy coating?

Accepted Answer

Your floor is ready when: it has been diamond ground to CSP 2–4; all existing coatings and adhesives have been fully removed; moisture content is within system specifications (tested with a moisture meter); and any cracks or spalls have been repaired and cured.
