Constraints
weber.plast P should not be used on waterretaining structures or in situations where 'ponding' of water may occur.
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.
Always follow the instructions on the packaging.
Preparation
On new, clean, dry, sound substrates priming is not generally required. However, if the substrate is old and porous or very dense it should be primed with weber PR310.
New surfaces should be clean, sound and dry. Existing walls, with traces of lichen, moss or fungal growth, should be treated with weber CL150 fungicidal wash, in accordance with the manufacturer's instructions.
Brush down to remove all traces of loose or flaking material.

First coat
Apply weber.plast P silicone enhanced paint diluted with water by approximately 15 - 20% by brush or roller.
Second coat
Apply a second, undiluted coat when the first coat is dry, normally between 6 and 24 hours.
