If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to amend some clauses to suit the final project-specific version.
The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.
This section relates to Dulux AcraTex NZ acrylic and polymer-modified cement-based exterior textured plaster systems, applied by hand, pump or hopper gun over:
Modify or extend the above description to suit the project being specified.
This section covers specialist high build coatings, with or without a textured surface, applied by trowel, spray or roller techniques.
While specifically written to suit a range of interior surface finishes, this section could also be adapted to cover similar exterior coatings. However such coating systems are product specific and require careful attention to product manufacturer's preparation and application requirements.
Many exterior coatings are installed as part of a weatherproofing system, including joint sealing/filling. Care is again needed to ensure that both the substrate and coating manufacturer's requirements are strictly adhered to.

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.

Inspect and test the surfaces of existing painted substrates to ensure that they are capable of supporting the new coating. A "cross hatch" adhesion test as an absolute minimum is mandatory, even on a substrate that appears to have a sound firmly adhered paint coating. Carry out testing in many locations and in areas just under window sills, the weather side of the structure and along the lower part of the wall.
Remove previous coatings in any areas that fail the adhesion test.
Remove loose or flaky paint (as judged by an adhesion test), dust, dirt, salt deposits, mould/fungi and any other surface contaminants with Dulux Prep Wash. High pressure water blasting is highly recommended as a standard procedure for cleaning the surface; it will also give a good indication as to its integrity.
Repair or fill large cracks and flaws with a suitable patching compound. Smaller cracks (up to 1 mm with Dulux AcraTex 968 Elastomeric 201 or with Dulux AcraTex AcraShield Advance) do not need to be filled as these will be bridged by the topcoat.
Where the previous coating is removed back to the bare substrate or repairs have been carried out, spot priming will be required. Dulux AcraTex AcraPrime 501/1 water based primer is recommended, unless the surface is particularly powdery and friable, in which case Dulux AcraTex AcraPrime 501/2 solvent based is recommended.

Remove covers and masking carefully and at the correct time, to avoid damage to or lifting of the coating edge. Clean adjoining surfaces, glass and fittings of contamination.
Remove debris, unused materials and elements from the site relating to plaster system application. Replace damaged, cracked or marked elements. Leave the whole of this work to the required standard.

Customise the attached schedules or substitute a schedule prepared using the DuSpec system.
When specifying texture coatings Dulux recommend that consideration should be given to the type and profile of the texture and preparation of the substrate to achieve the specified texture as this will impact on the applied m², rate. Confirmation via a sample of the texture profile is highly recommended (site sample applied by the contractor is preferred) prior to final pricing sign-off by the contractor administrator.

When specifying texture coatings Dulux recommend that consideration should be given to the type and profile of the texture and preparation of the substrate to achieve the specified texture as this will impact on the applied m² rate. Confirmation via a sample of the texture profile is highly recommended (site sample applied by the contractor is preferred) prior to final pricing sign-off by the contractor administrator.
Contact a Dulux representative for a texture sample.
