Finishing weberend LAC

In the process of the installation of webertherm XM and weberend MT, there are a number of criteria that need to be adhered to as part of best practice in the finishing elements of weberend LAC in advance of the application of weberplast TF or webersil TF.

To avoid compromising the bond between the weberend LAC and the texture coatings that may lead to bubbling and blistering or full delamination of the coatings, the following advice should be observed:

weberend LAC must be finished with a sponge float; leaving the work flat off the trowel or finishing with a spatula or steel trowel will inhibit bond of the two materials. A figure of eight motion should be adopted with a suitable sponge float across all the freshly applied render as it starts to take up.

Depending on the climatic and drying conditions, a period of 3 to 7 days must pass before progressing with the system installation from the finishing of the weberend LAC to priming. The application of weber PR310 primer is an essential part of the process and at no time should be omitted. A minimum of 24 hour period from priming should pass prior to application of textured coatings.
