Preparation & Application

Preparation

All surfaces must be sound, clean, dry and free from any material which may impair adhesion, and lightly floated to provide key. Scaffolding must be independently tied to allow uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified.

To avoid dampness and discolouration rendering should be avoided below DPC or within 150 mm of ground level. All surfaces must be suction free to ease application and texturing as well as accentuating the whiteness of the material. For this purpose, prime the surface with either white weber PR310 or a dilution of 1 part webertec latex.

alpine must be applied before the priming coat has fully dried.

Mask around the areas where material is to be applied. Masking tape must be removed before the material has dried out.

Mixing

Mix with clean water at a rate of approximately 6 litres per 25 kg bag, using a clean tumble mixer or suitable drill with whisk attachment.

Mix for 3 - 4 minutes to give a workable consistency. Allow to stand for 10 - 15 minutes before re-mixing for maximum workability.

Mix only sufficient material for use within the hour.

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

Trowel apply alpine as a tight coat while the primer is still tacky. When being properly spread, the material tends to 'chatter' under the trowel.

To obtain the travertine texture, draw a wood float across the face of the work with the minimum of pressure, in sharp horizontal or vertical strokes in one direction only. It is essential that this is carried out before the material stiffens on the wall.

As a contrast, the reveals to doors and windows may be 'dragged' vertically when the main areas are textured horizontally.

To obtain the circular texture, the material should be finished with a light circular action.

To prevent joints from showing, application should be continuous up to angles or features.

To maintain the texture at internal angles or close to soffits, the edge of the float should be pulled lightly in short strokes away from the angle.

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

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

Good practice
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

Cleaning

Clean equipment by washing immediately after use with clean water. Do not dispose of waste material into drainage systems.

Packaging, Health & Safety

Packaging

alpine is supplied in 25 kg bags.

Coverage / Yield

alpine: For each mm of thickness, you will require approximately 1.52 kg per m2. When applied at the correct thickness of 3mm, coverage is approximately 5 - 6 m² per 25 kg bag.

Priming coat: Approximately 4 m2per litre of white primer or 15 - 20 m² per litre of webertec latex after dilution 1:3 with water.

Note: These estimates take no account of wastage and may vary according to the type of surface involved.

Storage and Shelf Life

When stored unopened in a dry place at temperatures above 5°C, shelf life is 12 months from date of manufacture.

Health and Safety

Contains cement (Contains chromium (VI). May produce an allergic reation). Harmful by inhalation. Irritating to eyes and skin.
Keep out of reach of children. In case of contact with eyes, rinse immediately with plenty of water and seek medical help. After contact with skin, wash immediately with pleanty of soap and water. Wear suitable protective clothing, gloves and eye/face protection.
