Floor coating compositions

A process for the application of a floor coating comprising mixing a floor coating composition with a base catalyst C and applying the obtained ready to use floor coating composition to a surface of a floor,

• wherein the floor coating composition is a Real Michael Addition (RMA) crosslinkable composition comprising at least one crosslinkable component comprising reactive components A and B each comprising at least 2 reactive groups wherein the at least 2 reactive groups of reactive component A are acidic protons (C—H) in activated methylene or methine groups, and the at least 2 reactive groups of reactive component B are activated unsaturated groups (C═C) which reactive groups react to achieve crosslinking by RMA reaction between said at least one crosslinkable components in the presence of the base catalyst (C),
• wherein the crosslinkable component comprising reactive component A is a polymer that is modified with fatty acids and is modified with reactive components A in the main chain, pendant, terminal or combinations thereof,
• wherein the viscosity of the crosslinkable polymer comprising reactive component A as measured at 23° C. according to DIN EN ISO 3219/A.3, is from 15,000 to 200 mPa·s and
• wherein the crosslinkable component comprising reactive component A has a weight average molecular weight Mw between 500 and 10000 g/mol.
