Preparation & Application


Calcium silicate panels
Ensure panels are securely fixed to frame, providing a rigid in-plane surface without deflection or edge protrusions. Existing masonry substrates
Treat surfaces with weber CL150, a biocidal wash, to remove any traces of organic growth.

Where there is inadequate key, apply weberend stipple as directed on the data sheet.
Mix and apply weberend POC to produce a level, in-plane background. Lightly brush scratch and allow to dry. Refer to the Product Data Sheet for further information.


Mix and apply the weberend LAC coat approximately 3 mm thick. Lay in the meshcloth and apply a further 2 - 3 mm of weberend LAC. Sponge finish to achieve a flat finish. Allow to dry.

Prime the surface with the appropriate primer. Allow to dry.

Apply the selected textured finish.

In order to achieve high-quality results, always refer to the individual Product Data Sheets before starting any works.

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



Products required

Beads, trims and flashings
Render only beads are available in coated galvanised, stainless, coated aluminium or rigid plastic in 3 m and 2.5 m lengths.

Trims and flashings such as oversills and copings, are available in PPC aluminium in 2.5 m lengths or made to order.

Levelling coat
(on masonry where required)
weberend POC is a polymer-modified, low density, cement based render, that can be applied up to 15 mm thick in one or two passes.

Adhesive coat

weberend LAC is a factory batched mortar for scrimming.

weber PR310 is a pigmented liquid paint and is an effective method of preparing substrates by reducing suction and providing a colour wash prior to the application of the chosen textured finish.

Synthetic textured coatings
A range of textured coatings is available in a wide range of NCS colours.
