The invention relates to a foam composite material which comprises a material in web form impregnated with a curable resin. The resin in the foam composite material is in the B-stage. The foam composite material further contains expanded thermoplastic particles which are essentially uniformly distributed in the resin and in the web material. The invention also relates to the use of this foam composite material as a means for surface modifying wood-based substrates, which preferably are uneven, e.g. plywood.
