25Kg Silver Cullamix

About this product : Tyrolean and rubbed-tyrolean finish

• Suitable for internal or external use
• Suitable for most environments - coastal, town suburban and rural

This list is not exhaustive and other smooth, flat surfaces may be considered.
In addition, brickwork and blockwork may be coated where the joints will be accepted as a feature.
The substrate must show some suction to achieve the cullamix tyrolean texture.

 Features and Benefits:

• Pre-blended - requires only the addition of clean water on site
• Durable and weather resistant
• Through coloured - requires minimal maintenance and no subsequent painting
• Suitable for most environments: coastal, suburban and rural
• Can be used as an attractive, soundabsorbing textured finish on internal render

Preparation:

• All surfaces must be sound, clean, dry and free from any material which may impair adhesion. Rendering should be of good alignment, finished with a wood or plastic float and unkeyed.
• Scaffolding must be independently tied to allow for an uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration must be rectified.
• To avoid dampness and discolouration external finishes should be avoided below DPC or within 150mm of ground level. Mask around the areas where material is to be applied. Masking tape must be removed before the material has dried.
• Expansion joints should be included as required by the substrate and carried through all applied materials.

Mixing:

• Mix 5 measures of cullamix tyrolean with 2 measures of clean water in a suitable container. Mix for 3 - 4 minutes to a thick, pourable consistency.
• Mix only sufficient material for use within the hour. Stir frequently to avoid settlement.
• To ensure colour consistency, the materials required for complete and adjoining panels should be of the same batch number or be thoroughly mixed together before use.

Application:

cullamix tyrolean is applied using a handoperated machine. Machines may be hired from local hire shops.

cullamix tyrolean may also be applied by an open hopper spray machine. Finer textures are more typical of applications using this type of equipment.

The tyrolean finish is obtained by building up several passes to a finished thickness of 4 - 6mm. Care should be taken to leave sufficient time between passes to avoid merging and patchiness in the texture. The direction of application should be varied with successive passes.

Splashes and overspray should be removed immediately with clean water.

For a rubbed tyrolean finish, the application of cullamix tyrolean as above must be of the highest standard. When this is hard, but not fully cured, remove the peaks by rubbing in circular action with a carborundum stone. Brush out any dust on completion.

Curing: Curing with a fine spray of clean water may be necessary during rapid drying conditions. In hot climates curing as above is essential for 3 - 5 days after application.

Protection: Protect from unfavourable weather conditions during application and curing.

Note: As with all cement-based products, cullamix tyrolean may be subject to lime bloom. The likelihood of lime bloom occurring is increased when applied in adverse weather conditions or if the background is damp.

Do not apply:

• If frost is forecast within 24 hours of use
• In damp/wet conditions
• In temperatures below 5°C or above 30°C
• On elevations in direct sunlight or where the substrate is hot

Coverage / Yield

For each mm of thickness, you will require approximately 1kg/m².

When applied at a thickness of 4 - 6mm, coverage is approximately 5m² per 25kg bag.

Note: These estimates take no account of wastage and will vary according to the type of surface involved. Coverage is dependent on the texture applied and suction of the backing surface involved.
