Masonry mortar, repair mortar and screeds
Three product types are compared: thin-bed masonry mortar for aerated-concrete and similar blocks (EN 998-2, compressive classes M5 or M10), structural repair mortar (EN 1504-3, class R3 means at least 25 N/mm² compressive strength) and self-levelling underlayment (EN 13813, e.g. CT-C20-F6 for a cement binder, CA for calcium sulphate). Gypsum plasters are not compared in this edition.

How we compared
Products are grouped by the standard class they declare (for example EN 12004 C2TE S1). Each competitor figure is copied from that manufacturer's own public technical data sheet or official product page, linked in the column header with the date it was read. Figures are shown as published: test conditions, market versions and editions differ, so a number points to the data sheet; it does not prove equivalence. Where a data sheet is silent the cell says so, and nothing is estimated. EuroFix figures come from the EuroFix data sheets on this site. The guide contains no ratings, scores, rankings or verdicts.
Trademarks
All product names and brands are trademarks of their respective owners; EuroFix is not affiliated with or endorsed by any of them. Listing a product here does not mean it can replace another on site: check the data sheet, the declared class and the substrate before substituting.
Comparison matrix
Rows are product types grouped by declared class; each cell names the manufacturer's product and links to its data sheet. A dash means no product of that type was compared in this edition.
