cullamix tyrolean

Prepare

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 150 mm 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.

Mix

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.

Apply

Spray equipment

cullamix tyrolean is applied using a hand-operated machine available from suppliers of Weber products. Alternatively, 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.

Cure

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.

Protect

Protect from unfavourable weather conditions during application and curing.

Please 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.

Clean

All equipment must be washed with clean water immediately after use. Waste material should not be emptied into drainage systems.
