The Sovereign Black Mould Spray is used to sterilise mould-infected surfaces before redecorating. It may also be used as a maintenance wash to control mould or algae where painting is not possible or desired. It can also be sprayed around bath and shower areas to help control mould growth on sealants and grout.Ready to use.
 
A second application allowed to dry on surface will delay return of any mould. When used to help prevent mould growth in bathrooms, it should be sprayed on to surfaces at least once a week. Do not rinse off. Service life depends on local conditions, i.e. condensation will reduce the expected service life.
