Application Tools
Low pressure spray
Relative to Project Substrate and Specified Finish - refer to Project Specific Duspec Specification and Acratex® Substrate Guide.
Garden pressure atomiser/airless spray
A sample area should be trialled first then checked for the presence of bondbreaker.
Suitable substrates: Tilt Up/ Off Form Concrete/ Pre Cast Concrete
Commence application, working from bottom of panel upward.
Apply using an airless spray unit (eg Graco 695 with a .0015 - .0019 tip at 1000 psi) or a low pressure knapsack spray unit.
Large panels should be articulated into manageable work areas, always maintaining a wet edge ensuring rinsing of TiltWash is actioned prior to the area drying. If TiltWash dries, re-apply TiltWash to the affected area and rinse thoroughly.
Flood the area with an excess of material with a heavy spray rather than a thin jet or light mist. This will produce a foaming wave of excess material descending down the panel.
As TiltWash is applied the panel should take on a darkened appearance. Should this not happen, apply a second coat of TiltWash and consult with Dulux AcraTex if the panel does not darken (excessively applied water based bondbreaker may be the cause).
NOTES:
1. Chemical goggles, gloves and a mask should be worn at all times whilst pouring and applying TiltWash.
2. Application of TiltWash should be with an airless spray unit or low pressure knapsack spray only.
3. Application of TiltWash on large panels is a 2-man procedure, one to apply TiltWash the other rinsing with water. Never allow TiltWash to dry before rinsing.
RINSING TILTWASH
Rinse panel with a flood of water (heavy spray not jet) deluging panel from top to bottom.
Ensure extra care is taken whilst rinsing to ledges, sills and all fixtures on panels.
A second rinse should be performed whilst panel is still wet from initial rinse. This is to make sure all remnants of bondbreaker and TiltWash are removed.
This product should not be released into any watercourses, drains or gutters neat or diluted and should be contained and disposed of under local waste management procedures. An environmental duty of care must be executed at all times whilst using this product.
NOTES:
PRIOR TO PAINTING
Cross- hatch adhesion and pH tests must be performed as per Australian Standard AS2311-Painting Buildings and AS1580-Methods of Testing Adhesion (current editions) prior to commencing full-scale works.
pH readings must be below 10 before coatings can be applied.
