Bathroom and toilet humidity
Ventilation, drying habits and constant moisture can affect painted surfaces and encourage mould growth.
MOULD TREATMENT
Mould treatment starts with understanding the wall condition.
Visible mould, recurring stains or peeling paint can be frustrating. A fresh coat alone may not be the answer: surface condition, moisture, ventilation and any underlying leak or seepage need to be considered before repainting is recommended.
When painting alone may not be enough
Mould can return when the underlying source of moisture remains. If there is an active leak, condensation issue, water ingress or building defect, that cause may need to be resolved by the appropriate party before paintwork can provide a lasting cosmetic finish.
Condensation or seepage
Air-conditioning condensation, pipe leaks, external water ingress or inter-floor seepage need separate attention before repainting.
Existing paint failure
Peeling, chalking or stained paint may require removal, treatment, repair, primer or sealer within the agreed scope.
How A&J approaches a mould-affected wall
Review the visible condition
Photos and, where needed, a site visit help determine the affected area, paint condition and whether there are signs that need investigation before painting.
Clarify the limits of the paint scope
If an active water source or building issue is suspected, it should be addressed first. Painting does not repair leaks or eliminate the cause of continued dampness.
Agree suitable surface preparation
The agreed work may include removing loose material, cleaning/treating affected surfaces, repairs, primer or sealer, depending on the condition and scope.
Apply the agreed finish
Once the surface is ready, the selected paint system is applied as agreed. Ongoing moisture control and ventilation still matter after handover.
REAL A&J PROJECT
Mould treatment and repainting
Work within scope: the visible condition was assessed, then the agreed preparation and finish were completed.
Results depend on the underlying condition and whether the moisture source has been addressed.
