This product data sheets shall be read in conjunction with the Dulux specification.
To ensure colour uniformity and for optimum performance, Dulux recommend a full coating system including a Membrane topcoat. For all systems, the Texture &/or Base Coat should be tinted in accordance with Tint Guide to the specified topcoat colour (or a colour as close as possible to the specified colour as product and Acratex tint rules allow).
Important: Not all colours are suitable for exterior use. Ensure that you have adequate tinted stock to complete the job in one application. All material must be thoroughly cross-mix to ensure tint uniformity. It is recommended to hold a volume of finish material for future maintenance touch-ups
Practical spreading rates will vary from quoted theoretical figures depending on substrate porosity, surface roughness, overspray losses, application methods and environmental conditions (e.g. wind).
• Do not apply paint if Relative Humidity is above 85% or temperature is within 3°C of Dew Point.
• Do not apply if the surface temperature is greater than 40°C or below 10°C, or likely to fall below 10°C during the application or drying period.
• Dry times apply to a single coat at recommended spread rate and at 25°C and 50% Relative Humidity
• Allow longer times under cool, moist, or still conditions and or when applied at high film builds.
• Protect from dew, rain and frost for 48 hours when apply at the recommended spread rate.
• Avoid application in hot, windy conditions or on hot surfaces cool the surface by hosing with water and paint the cool damp surface.
• The exterior texture coatings should be cleaned on a regular basis.
• This will help maintain your overall aesthetic appearance and preserve your Acratex Texture coating system.
Cleaning once every year will remove light soil as well as grime and airborne pollutants refer Dulux Acratex Care & Maintenance Guide.
All surfaces must be thoroughly clean and free of all contaminants, dirt, surface chalk, grease, mould, mildew, wax, loose or flaky paint, form oils, release agents and mortar splashes. Metal, tie wire, etc. on surface must be removed or treated against corrosion. Surface imperfections and irregularities should be levelled and patched and completely flush to surrounding surfaces.
Remove trowel marks using Hebel® Sander.
Trowel and Hawk finished with a plastic float
Use masking to protect adjacent areas. The area should be patched and primed ready for final texture coat.
Hebel® PowerFinish is applied by hawk and stainless steel trowel, then finished in a circular motion with the plastic finishing float to achieve an even granular appearance.
Two applicators are required for most areas - one applying the other processing the finish. Delivery must be to a uniform thickness. Allow the material to stand for a short time before "rubbing up" with float to produce the desired pattern/texture. Application must be in a brisk uniform fashion terminating when the whole area is complete, banded by a natural break such as an expansion joint, corner etc. Application commenced on a single area must be completed uniterrupted.
