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 the supply and installation of Exsulite-Kooltherm Cladding System by Dulux AcraTex NZ based on cladding sheets fixed to timber/metal framing with a drained cavity and an applied textured surface finish.
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 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.

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 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.
