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.
Provide a material manufacturer/supplier warranty:

All window and door joinery to be installed and all penetrations made watertight prior to the commencement of plastering.
Fitting of window and door joinery with air seals, flashings, flexible flashing tape and MS sealant is the responsibility of the window installer
Apply Dulux Acratex RenderWall P400 render coat 3 mm minimum thickness. Embed mesh into the wet plaster. Overlap each successive length by 100 mm minimum. Apply diagonal reinforcement strips at all corners of windows, doors and other exterior openings.
Apply Dulux Acratex RenderWall Float Finish Medium to produce a granular texture appearance to Dulux AcraTex NZ requirements.
Apply Dulux AcraTex AcraPrime 501/10 Green Render Sealer over fresh green masonry surfaces. Apply with roller, brush or airless spray.
Apply Dulux Acratex 951 Super Trowel On 1mm, or Dulux AcraTex 951 Coventry Coarse by steel trowel to the thickness of the aggregate within the emulsion, then float with either a plastic finishing float or polystyrene for the coarser grade aggregate products.
Apply Dulux AcraTex 952 Spray on 2mm using a Hopper Gun with a 4mm tip at 50psi for a 1mm texture and 6 - 8mm tip at 50psi for 2mm texture, on second pass reduce pressure to 30psi.
Apply the specified number of coats of Dulux AcraTex AcraShield Advance with roller, brush or airless spray to the recommended spread rate as per DuSpec specification shown in SELECTIONS.
Apply the specified number of coats of Dulux AcraTex 968 Elastomeric 201 Matt with roller, brush or airless spray to the recommended spread rate as per DuSpec specification shown in SELECTIONS.
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 650 µm 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.
Apply Dulux AcraTex AcraPrime 501/1water-based primer/sealer.
Apply the specified number of coats of Dulux AcraTex AcraShield Advance with roller, brush or airless spray to the recommended spread rate as per DuSpec specification shown in SELECTIONS.
Apply the specified number of coats of Dulux AcraTex 968 Elastomeric 201 Matt with roller, brush or airless spray to the recommended spread rate as per DuSpec specification shown in SELECTIONS.
All freshly applied materials to be protected from inclement weather for a minimum of 24 hours after application.
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 the plaster system application. Replace damaged, cracked or marked elements. Leave the whole of this work to the required standard.

Substitutions are not permitted to the following, unless stated otherwise.
If substitutions are permitted modify the statement above, ensure the NO SUBSTITUTIONS clause from GENERAL is treated the same.
Select the options to suit the project and delete options not specified.
SELECTIONS is for providing details of the actual selections to be included in the contract works including model numbers, colours and other information necessary to ensure that the correct materials are supplied and installed.
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 rates. 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.
