Observe without experimenting
Photograph the mark dry, in normal light and from a low angle. Describe whether it changes the colour, reflection or feel. Note the spill or cleaner involved, and do not apply an abrasive to test what happens.
Share the treatment history
Tell the team about sealers, waxes, films and earlier polishing. A coating issue can complicate diagnosis. Supplier details and the original finish are helpful, particularly if you are unsure whether the material is marble or another natural stone.
Match the proposed work
Restoration, stain treatment, sealing and protection film are different scopes. Ask which problem the proposal addresses and what may remain afterwards. A treatment for one mark is not a promise against future damage.
Describe the mark in ordinary language
Useful descriptions include a pale ring visible only in reflection, a dark patch that remains when dry, or an area that feels different from the surrounding stone. You do not need to diagnose it yourself. Tell the team what happened, what was spilled and when the change first appeared, then let the assessment establish the appropriate next step.
Consider section boundaries
A restoration can need to extend beyond the visible mark to achieve a consistent finish. Ask how the treatment will meet a splashback, return, sink edge or adjoining untouched area. If protection is being considered afterwards, coordinate preparation and finish rather than arranging separate treatments that have not been assessed together.
Questions, answered.
What is the next step?
Send photos, your suburb and the relevant material or fitting details. The team will clarify the proposed work, its limitations and the quote before an appointment is agreed.
