Material Safety Datasheet
Preparation & Application
webersil TF is a wet premixed material. It is applied to prepared surfaces on to a tinted primer.
Prime the prepared surface using tinted weber PR310 applied by brush or spray. Ensure complete coverage of wall to be treated to prevent 'grinning through' of the background. weber PR310 is of low viscosity and easily applied. Check batch numbers and colours of material required to complete working area. Stir well in buckets and if required, make minor adjustments to workability with a little water, thoroughly mixed in.
Apply webersil TF with a steel float and hawk to work area. Use a thin plastic float to finish webersil TF. Evenness of cover and texture are of paramount importance.
Agree an acceptable finished appearance on a sample area with architect or supervising officer before proceeding with large-scale application. Maintain a steady flow of application and keep a wet edge on all incomplete edges.
webersil TF is a synthetic material, therefore weather conditions for applying and drying are critical. Dry weather may not be enough if the humidity is high and the drying potential of the atmosphere is low. A dry atmosphere which can be foreseen for about 36 hours is preferred to effect initial curing and prevent wash-off. Otherwise proper weather protection for the work may be necessary.
Synthetic mixes can stain and are difficult to remove so protect vulnerable areas thoroughly and wear protective clothing, particularly gloves.
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
