In the preparation of the composition according to the invention, the liquid constituents are first excepted of the catalyst and the solid components are each mixed together in a mixer, immediately put into another mixer in the specified ratio before the components are manufactured, the liquid components are then already mixed homogeneously with the catalyst. Afterward this mass according to the invention is in a corresponding shape that corresponds to the components, poured and shaken until the air bubbles have escaped. The mass is then allowed to harden.

Depending on the constituents of the composition according to the invention, it can happen that a separation can occur during the Rütteins in such a way that the heavier constituents sink to the bottom. In this case, the composition of the invention is used in its preparation thixotropic powder or paste z. B. on the basis of silica (Aerosil) added; this additive has long been used in the manufacture of plastic sheets and prevents the individual components from separating.
In a corresponding manner, multilayer boards which have more than two layers can also be produced with the compositions according to the invention. A multilayer board according to the invention is shown in section in the drawing: a polystyrene core 6 is provided on both sides with a layer 5 of glass fiber reinforced cement mortar (board spray grout). This is followed by the following layers: a layer 4 as an adhesion promoter based on polyurethane, an elastic buffer layer 3 made of UP resin, a glass silk mat 2 which is laminated with UP resin, and a fine layer 1 made of light-stabilized, unsaturated polyester resin Color pigment with a layer thickness of about 0.6 mm.

In principle, single-layer or multi-layer components can therefore be used are produced, d. H. Components that only consist of a single homogeneous Layer or different layers! Composition exist, e.g. B. with a difference borrowed filler proportions.
