Excessive mould growth to ceiling, cornice, walls and shower grout caused by condensation.

PRELIMINARY REPORT:

• Exhaust fan was inadequate and not extracting enough air.

• Paint on ceiling and walls was thin and allowed moisture absorption and therefore promoting mould growth.

TREATMENT:

• Hepa vacuum to all affected surfaces.

• Anti-Microbial treatment to all affected areas.

RECOMMENDATIONS FOR THE OWNER:

• Install new exhaust fan above the shower that extracts a min of 280m3 of air per hour.

• Paint ceiling, cornice and walls using a mould inhibitor additive or wet area paint with a min of two coats.

• Apply a water based grout sealer to the shower recess tile grout to help resist water absorption.

CONCLUSION:

This bathroom will be ready for the upcoming winter and should be mould free even with a family of four.
