BS EN 13914-1:2016 PDF Download

BS EN 13914-1:2016 is a European standard that provides requirements and recommendations for the design, preparation, and application of external rendering. It covers renders based on cement, lime, or other mineral binders, as well as organic binders. The standard applies to various types of backgrounds, including both new and old surfaces, and addresses the maintenance and repair of existing render work.

However, there are certain aspects that the standard does not cover. This includes the use and application of special renders for specific structures, such as coatings for liquid retaining structures or backgrounds to cladding systems. It also excludes the structural repair of concrete, the installation of external thermal insulation composite systems (ETICS), the specification and use of sealants for joint sealing, renders on historical monuments or buildings in protected areas, and the design and installation of flashings at windowsills and elsewhere.

Due to the diverse materials, practices, and climatic conditions across Europe, the standard acknowledges that not all aspects can be detailed enough to be fully applicable in each country. Each country is encouraged to provide complementary guidance that aligns with the standard's recommendations but may include more specific information tailored to local conditions. Footnotes within the standard identify areas where additional guidance may be necessary.
