 It is important to ensure that all personnel on site have access to accurate, up to date technical information on the many products, materials and equipment used on a project.  In most cases individual products are not used in isolation, but form part of a building process. Also a particular manufacturer's and/or supplier's requirements for handling, storage, preparation, installation, finishing and protection of their product can vary from what might be considered the norm. Access to technical information can help overcome this potential problem.

Warranties

Use for listing all warranties relating to this section.  Supplier and manufacturer warranties are those that are freely offered by the supplier or manufacturer, similarly installers and applicators.  They are usually in their standard form and subject to their terms and conditions. Check the general section 1237 WARRANTIES for the date of commencement of warranties; which is normally practical completion of the contract, although not all suppliers, manufacturers, installers or applicators will agree to this.  Refer to the chosen conditions of contract as it may also contain information on warranties.

1.5
WARRANTY

Warrant this part of the work under normal environmental and use conditions against failure of materials and execution.  The Sto Applicator must complete the Sto quality assurance compliance procedure form and applicator warranty.  The StoLastic Jointing System and StoArmat Plaster System are warranted as follows:

Materials:

15 years from date of practical completion

Execution:

5 years from date of practical completion

Requirements
1.6
QUALIFICATIONS

Use only applicators registered to apply the Sto plaster render systems.

1.7
NO SUBSTITUTIONS

Substitutions are not permitted to any specified Sto plaster render system.

1.8
PROTECTION OF NEW PLASTER

Provide protection systems as required by the manufacturer to protect fresh plaster from adverse weather conditions.

Normally required curing procedures can be altered when acrylic-modified plasters (bonding agents) have been specified.  Such plasters may only need limited protected from direct sun and strong, drying winds for 16 - 24 hours.  Consult the manufacturer's requirements in this clause or write another.

1.9
INSPECTIONS

Allow to inspect the whole of the work at each stage. Determine a programme for inspections including notification when each part and stage of the work is ready for inspection prior to the work commencing.

 

If requested permit representatives of Stoanz Ltd to inspect the work in progress and to take samples of their products from site. Refer Sto product manual.

The level of inspection will depend on the nature of the project and will range from full for large or complex projects, through to intermittent for straightforward work, to occasional for initially establishing the standards of execution.  Refer to AS/NZS 2311 Appendix C, Inspection and Testing, for more background.

JOINTING APPLICATION

Ensure tapered joints have been thoroughly cleaned to remove any factory slurry.  Prime fibre cement sheets with one coat of Sto Putzgrund by brush or roller to the total surface area to be plastered.  All joints in the fibre cement sheets to be flushed using StoArmat.  While the plaster is still wet lightly embed Sto 65mm jointing tape into the surface ensuring the joint is level with the surrounding sheet plane.

3.25
MESH COAT REINFORCED PLASTER

To dry primed surfaces apply one even base coat of StoArmat reinforcement plaster at approximate thickness 1.5mm.  While plaster is still wet lightly embed Sto mesh ensuring adjacent drops of mesh are overlapped by a minimum of 75mm.  Float surface to ensure mesh is embedded into the Sto Armat coat, allow to dry then apply one further coat of StoArmat at approximately 1.5mm thick to leave the plane even surface free of voids or deviations.  Once dry remove any slight ridging with a Sto rasp ready for topcoat.

3.26
FINISHING RENDER

Apply selected Stolit K or MP coloured finishing render applied with a stainless steel trowel gauging to the thickness of the aggregate size and finished with a plastic float to the requisite pattern.  Apply Stolit MP or MPNatural in two coats and finish with a float and judicial use of a damp sponge.

Thickness and styles of renders varies between Stolit K- 1 / 1.5 / 2 / 3mm & Stolit MP/MP Natural - sponge.  Refer to Selections to choose required finishing render.  Refer to SELECTIONS for preferred finish.
