The invention relates to a method for coating, gluing or connecting surfaces of mineral materials with a two-component plastic resin, selected from a hydrophobic polyurethane resin and a hydrophobic epoxy resin, by applying the plastic resin on the surface or connecting the surfaces of the mineral materials with the plastic resin and by leaving the plastic resin to harden. The invention is characterized in that the plastic resin contains 0.01 to 10 percent by weight of one or more hydroxy or alkoxy aminosilane compounds of general formula (I), wherein X independently of one another represents OH, CH3, O[CH2]pCH3; Y = [CH2]t, [CH2]rNH[CH2]s; R, R' H, [CH2]tCH3; t = 0 - 10; n = 1 - 3; p = 0 - 5; m = 4 - n; r, s independently of one another represent 1 - 10. |
