The floor layer did not tell us that it was about a gap, but (according to my understanding at that time) that the residual moisture in the screed is first noticeable at the baseboards, namely because they can absorb water and swell, and as a result, the floor covering may not settle properly and waves may form in the floor.
It is truly astonishing what one has to read regarding statements from craftsmen! The above statement is complete nonsense and does not demonstrate any professional competence! If a floor covering, which in the broader sense also includes the baseboards, is not installed on a dry substrate, then this is clearly due to a failure of the contractor in light of his inspection and duty of care obligations. The joint between the lower edge of the baseboard and the screed surface is not a defect. Every mineral screed tends (cement screeds more, calcium sulfate screeds less) to deformation due to drying. In a standard cement screed, this can also be around 5mm without this being objectionable! Neither the screed installer nor the client has any influence on this. And if a 2.5m long, relatively rigid baseboard with an MDF core is installed in the wall area, well, then a gap will appear here and there at the bottom edge. The only aspect to consider afterwards purely visually is the aesthetics. If the client does not want to accept this, an acrylic joint, almost color-matched to the baseboard, can be applied neatly. In parquet flooring, this procedure is common. However, since parquet deforms in length due to climate, after curing, the sealant joint is cut through parallel to the surface of the covering with a thin cutter blade so that the wooden floor is not held fast. And the forces can be quite considerable with sealants, as I know from my own experience! Well, parquet is not the subject here. But the sealant joint conceals what no one is really responsible for, which is to be seen as material-specific with regard to the screed! --------------- Regards: KlaRa
