The present invention relates to methods of manufacturing composite products having a surface effect. In some examples described, a composite product has a simulated surface, for example a stone-effect surface formed by pressing a particulate-form surface material (30) and a sheet-form curable material (40) onto a substrate (44) having an open-celled structure. In other examples, a laminate product having a veneer is formed by pressing a veneer and a sheet-form material onto a substrate including a porous structure. The veneer may comprise a wood material. In other examples, a surface effect material is bonded to a skin by pressing a sheet-form curable material to a mold surface and the surface effect material. Where the surface effect material has a high thermal conductivity, the composite product formed can feel cool to the touch.
