heat reflective facade are required. Colours selected below the recommended
values will affect the warranty.
6. STOSERVICE ASSURANCE
Refer; StoService Assurance
for comprehensive guide
The Sto Render System should be cleaned annually by low pressure washing or
hosing down to remove surface contaminants with special attention to non-rain
washed areas (as required use a proprietary house wash sprayed on first with a low
pressure garden spray). When recoating is required at the 9 - 10 year period to
maintain long-term integrity this is carried out using StoColor façade paint over a
cleaned surface. Where a colour change is required Stoanz Limited should be
consulted for a specific specification.
An annual visual inspection is to be undertaken by the owner or their agent to check
for any physical damage or defects in the cladding or exterior building elements to
ensure any obvious faults are identified and repaired. Every two and half years the
building occupier will be notified to contact the Sto Contractor to carry out a
StoService inspection. On completion the Sto Contractor will issue a current
StoService certificate that will be recorded in the Sto warranty information so a longterm record of the service history is maintained.
