1. A floor structure on a base comprising a primer and a floor covering which is atop the primer and comprises a floor coating and/or an adhesive bond, characterized in that the primer is obtained from an aqueous dispersion of at least one acrylic polymer containing 0.001-0.2% by weight of at least one benzoxazole-based system, based on the total weight of the aqueous dispersion,
wherein
the aqueous dispersion has a viscosity one day after production of less than 3000 mPas, measured with a Brookfield DV1 viscometer with spindle 4 at 20 rpm at 23° C. and a particle size of 10-70 nm, and the primer has a penetration depth into the base of 1-10 mm, or
the aqueous dispersion has a viscosity one day after production of greater than 3000 mPas measured with a Brookfield DV1 viscometer with spindle 4 at 20 rpm at 23° C. and a particle size of 80-150 nm, and the primer has a dry layer thickness of 0.05-0.5 mm.
