The aim of this study was the evaluation of adhesion strength of surface coatings in lightweight foam core panels. Lightweight foam core panels were manufactured with 3, 4, and 5 mm face layers thicknesses and two press temperature of 130 °C and 160 °C. Face layers properties and also adhesion strength of acrylic and polyurethane coating on lightweight panels was investigated. The results showed that the surface soundness, surface roughness, and surface wettability were significantly increased in panels produced by 130 °C whilst the face layers thicknesses increased from 3 to 5 mm. Conversely, the surface soundness, surface roughness, and surface wettability were significantly decreased in panels produced by 160 °C whilst the face layers thicknesses increased from 3 to 5 mm. The results also showed that the adhesion strength of polyurethane coating was drastically higher than that of water-based acrylic coating. The highest adhesion strength was obtained in panels manufactured with press temperature of 130°C, face layers thickness of 5 mm and polyurethane coating.
