Wet Mix Texture Application RBS Reinforced Board Render System is a coating system designed for Plain Polystyrene Panels-EI FS (M Grade EP S Panels as per AS1366.3) and the QT Eco Series Wall Panels. The RBS System as a whole converts the original panel substrate properties to a highly weather resistant and environmentally stable exterior wall surface providing other than strength, protection and gives an aesthetic finish to the wall.

Prior to application please refer to the Product Data Sheet (PDS) for comprehensive product information and Material Safety Data Sheet (MSDS) for safety information.

STEPS	DESCRIPTION	SYSTEM PRODUCTS
Base Range Step 1: Strong Base Coat	Forming part of the Multitex Wall coating system, Multitexs DryMix Board Render is a superior quality hi-strength cement based, polymer modified render containing washed and graded medium silica sand, acrylic powder and proprietary additives. It is easy to apply, has excellent adhesion and strength. It does not require the addition of bonding agents. Multitex Board Render provides the ideal base for the subsequent application of Multitex Texture and Final Range coatings.	Base Range 1st coat Board Render, 2nd coat Medium Render, AR FG Mesh Coats: As required
Primer Range Step 2: Protective Primer Coat	Roller applied Multi-Prime is used as a protective undercoat primer for the MULTITEX coating system and is applied to the render substrate to unify the substrate porosity and reduces consolidates suction, it ensures maximum inter-coat adhesion and provides excellent key for following texture and topcoats. Multi-Prime can be tinted to required colour.	Primer Range: Multi Prime Coats: 1
Decorative Range Step 3: Decorative Texture Coat	The texture coat provides the desired look, finish, integrity, flexibility and long term durability to the entire cladding system. The trowel on textures generally is a one coat application, firstly using a steel trowel to spread evenly and secondly floating off with a plastic float. Can be colour matched to an extensive range. The roll on texture is also a one coat application, using different set of roller profiles fine, medium or a coarse finish can be obtained.	Decorative Range: Trowel Texture or Roll on Texture Coats: 1
Final Coat Range Step 4: Durable Top Coat	Roller applied Multitex Shield is recommended as the top coat for the system, this is a specifically designed product for exterior performance and durability, and is a protective coating for the base system configuration providing other than colour (in extensive range) flexibility, resistance to dirt pick up, resistance to atmospheric pollution, Ultra Violet, moisture ingress and salt penetration.	Final Coat Range: Multitex Shield Coats: 2

Dry mix texture application This system has an option at Step 1A to use dry mix decorative base range texture (not-tinted) in place of Step 3 coloured wet mix decorative texture, when selecting this option it is mandatory to prime and top coat the texture for colour, durability and system warranty.

STEPS	DESCRIPTION	SYSTEM PRODUCTS
Base Range Step 1: Strong Base Coat	Firstly Multitexs Multi-Grip is rolled on to the AAC panel to reduce the surface absorption and improve the strength of the brittle AAC substrate, Multi-Grip is a superior quality, highly alkaline stable 100% acrylic bonding agent. Secondly keeping the surface damp a base coat of Multitex Fibre Reinforced Render is applied to give a strong and webbed base coat helping load distribution on the AAC surface. Fibre Reinforced Render is superior quality cement based, polymer modified, fibre integrated render, it is easy to apply, has excellent adhesion and strength.	Base Range: 1st coat Board Render, 2nd coat Medium Render AR FG Mesh Coats: As required
Base Range Step 1A: Dry Mix Decorative Texture Coat	The texture coat available in either Fine or Coarse grains provides the desired look, finish, integrity and long term durability to the entire cladding system. The Dry mix trowel on textures generally is a one coat application, mixed with water on site, it is applied firstly using a steel trowel to spread evenly and secondly floating off with a plastic float. This texture is not coloured and to attain the colour required, texture surface has to be primed and top coated in the colour desired with two coats of Multitex Shield.	Base Range: Dry Mix Texture Fine or Coarse Coats: 1
Primer Range Step 2: Protective Primer Coat	Roller applied Multi-Prime is used as a protective undercoat primer for the MULTITEX coating system and is applied to the render substrate to unify the substrate porosity and reduces consolidates suction, it ensures maximum inter-coat adhesion and provides excellent key for following texture and topcoats. Multi- Prime can be tinted to required colour.	Primer Range: Multi Prime Coats: 1
Final Coat Range Step 4: Durable Top Coat	Roller applied Multitex Membrane is recommended as the top coat for the system, this is a specifically designed product for exterior performance and durability, and is a protective coating for the base system configuration providing other than colour (in extensive range) flexibility, resistance to dirt pick up, resistance to atmospheric pollution, Ultra Violet, moisture ingress and salt penetration.	Final Coat Range: Multitex Membrane Coats: 1
