AcraStone Finish Coat Medium Part A

This product data sheet should be read in conjunction with the Dulux specification.

 

Take suitable safety precautions while preparing your surface or sanding a previously coat/ coated, including wearing an appropriate respiratory mask.

 

To ensure colour uniformity and for optimum performance, Dulux recommend a full coating system including two to three topcoats.

For all systems, 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).

 

Ensure tint cups are mixed well using a power mixer.

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.

Exterior applications 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 coating system should be cleaned on a regular basis. This will help maintain your overall aesthetic appearance and preserve your Dulux AcraStone coating system.

Surface Preparation

Apply on clean dry surfaces, free of oil, grease, mould, dust or any other element that may affect the adhesion of the system. Clean the surface with degreasing product. Make sure that tiles are well fixed and not detaching.

Do not apply the product where there is rising damp.

Ensure moisture content is less than 10% as measured with standard moisture meter.

 

Application Procedure and Equipment

The Dulux AcraStone range of products are designed for application by professional applicators. Applicators must have completed a 'Microcement' application course and hold a current Dulux Trade account.

Mix Finish Coat Medium Part A with AcraStone Epoxy Resin Part B in a ratio of 10:1 by weight. Mix with drill for 3 minutes or until a homogenous mix is achieved.

The pot-life of the two components is 1 hour. Only mix the material that will be used by weighing out Part A and B.

Apply product using a stainless-steel Venetian Plaster trowel and build pattern into the first coat to desired finish appearance. Apply the second coat as a tight finish to even surface and to bring out pattern. 

Only small amount of sanding is required to remove very high points in first coat. Do not over-sand as pattern will be removed.

 

Spread rate varies between first and second coats:

1st coat - approx 2.5m2/L

2nd coat - approx 5m2/L
