European standard on rendering and plastering listed with 2026 date

Perinorm lists DIN EN 13914-2 — the European standard on the design, preparation and application of external rendering and internal plastering — with a date of June 2026.

Standards of this kind are the reference that specifications are written against. EN 13914 deals with the decisions that determine whether a render or plaster survives: substrate assessment, mix design, number and thickness of coats, detailing at movement joints, and the conditions under which application should and should not proceed.

ArtCoatings has not seen the text of the edition listed and cannot confirm whether it is a full revision or an administrative reissue. Standard bodies publish drafts, confirmations and revisions under the same number, and a listing date alone does not distinguish between them.

Why this matters

Decorative finishes fail at the substrate far more often than in the finish coat. When a standard changes its guidance on preparation, every applicator specifying against it has to revisit what they write — and every manufacturer has to check that their system’s declared performance still holds.

What remains unconfirmed

• Whether the listing is a revision, a confirmation or a draft.
• What has changed from the previous edition.
• The date the new edition becomes the reference for specifications.
