When it comes to choosing a natural rendering for a construction or renovation project, there are several options to choose from: lime, clay and linen. Each of these plasters has specific properties that influence their use depending on the type of support, climate and aesthetic requirements. In this article, we compare these three types of render to help you make the best choice.
