Technical data
weber PR340 is an effective method of preparing substrates by equalising or reducing excessive suction prior to the application of weber.rend fibrelite.
Constraints
The quality of application of this material depends on suitable operative skills and product familiarity.
Restrictions on weather conditions during application and curing must be respected.
Sound trade practices and printed instructions must be followed.
Good access and appropriate protection must be provided.
Application
Stir well in buckets prior to applying to the work area.
Apply to the wall surface using brush, spray or roller, ensuring complete coverage of all areas before over coating.
Where substrate suction control is required, weber PR340 can be used as a wet-on-wet application, with weber.rend fibrelite. The primer must be allowed to migrate into the prepared background before applying the weber.rend fibrelite - this will take a minimum of 20 minutes. The primer should have turned tacky with no visible surface film. The curing period will be dependent on suction of the substrate and prevailing weather conditions at the time of application.
Where wet-on-wet procedure is not being adopted weber PR340 should be applied at least 24 hours prior to application of weber.rend fibrelite. Once again, the drying period will vary according to weather conditions.
Spillages stain and are difficult to remove so:
- protect vulnerable areas thoroughly
- wear protective clothing.
Storage and Shelf life
When stored airtight in a dry place at temperatures above 5°C and protected from frost, shelf life is 12 months from date of manufacture.
Do not over-stack.
Health and Safety
