General Preparation
The finished quality of any job begins with proper preparation. CSR MiTex™ Advanced Coating Systems have been developed to suit a wide variety of substrates. The following preparation steps are common to all substrate types and should be strictly followed to ensure a quality finish is achieved.
Click on Substrate Preparation  for further preparation instructions for specific substrate types.

Surface
All substrates must be sound, and free from dirt, dust, mould, oil, grease, release agents, salt and other contaminants that might affect adhesion.

Weather Conditions
MiTex™ compounds must only be used when air and substrate temperatures are between 10˚C and 30˚C. Application in extreme heat or windy conditions should be avoided. Where possible stage the coating process to work in shaded areas.
In case of impending rain coating application should be stopped in time to allow the product to cure adequately. MiTex™ compounds must be protected from frost and rain for at least 24 hours after application.

Set Out
CSR MiTex™ recommends that large surface areas are broken down into smaller working areas for coating. This is especially important in high temperatures and windy conditions.
Planning for smaller working areas should take into consideration locations of joints to ensure aesthetics are not affected.
Isolated areas should be completed in a single application to avoid joint marks.
Never apply any of the MiTex™ texture compounds below the damp course level or to the face of retaining walls that may become damp.

Horizontal Surfaces
Exposed horizontal and near-horizontal surfaces that are coated with texture coatings may not prevent the ingress of water into the substrate. It is recommended that a slope of at least 30 degrees from horizontal be provided where texture coating is to be used. For lower slope surfaces, a flashing or suitable membrane should be used. The edges of all texture coated areas should also be protected to prevent water ingress.

Scaffolding
Steps or scaffolding should be used where required to enable access to all sections to be coated. Scaffolding should be designed and used in accordance with relevant safety practices.

Masking
Coating compounds drip and spill during application of both preparation and texture coatings. It is recommended that a protective covering is provided for all adjacent surfaces until work is completed. Suitable masking tapes and sheeting should be used to cover doors and windows and other surfaces requiring protection.

Metal components
Metal components such as fasteners, down pipes etc, which are in contact with the texture coating, must be suitable for use in exterior environments. All other foreign metals such as embedded nails, exposed reinforcing and tie wires must be either removed or treated against corrosion. The texture coating will not prevent the corrosion of untreated metal objects, and rust stains or blisters in the coating may result.

Tools
A range of recommended tools is available from CSR MiTex™ to suit the various systems. Please refer to system data sheets for tools and application recommendations.
