Features and benefits:
Not suitable for use on construction board substrate (concrete particle board/render board), use weberend MT - Not suitable for use on insulation board substrate, use webertherm XP.
Available in a range of 24 colours.
M20/160 Proprietary cement gauged render
M20/19 Proprietary cement gauged render
weber CL150 Fungicidal Masonry Wash.
For existing substrates, or where required on new substrates, drench apply CL150 wash and leave for 48 hours, then brush down to remove all moss/ growth.
Helps to provide a mechanical key.
Apply with a hawk and trowel in a tight layer 2–3 mm thick to the substrate. Texture the surface using a well loaded roller. Apply no more than 2–3 m² before texturing. It is important that the final texture achieved should be deep, heavy stipple finish with a minimum textured depth of 5–10 mm. Insufficient key will inhibit the render bond; this is particularly relevant on low suction substrates where capillary absorption is minimal. Leave to cure for 48 hours.
Glass fibre reinforcement
weber standard meshcloth.
To be installed in accordance with manufacturer's recommendations. Balanced, open weave glass fibre meshcloth, coated for alkaline resistance. 1 x 50 m roll.
Weber recommend incorporating weber standard meshcloth into the weberend aid key coat or to the first pass of the weberpral first coat, to areas of typical stress points in the construction.
