Functional Additive Solutions for European Building Material Manufacturers
Construction applications cover a comprehensive range of wall, floor, and exterior facade systems—from substrate preparation to final decorative and protective finishes.
Our portfolio includes mainstream dry-mix mortars, gypsum-based materials, exterior insulation ETICS/EIFS, floor leveling compounds, and architectural coating solutions.
As a leading manufacturer based in China, LANDU tailors high-performance functional additives to suit European climatic conditions, local construction practices, and unified EN standards, helping material producers stabilize formula performance and improve on-site construction efficiency.
If you are working on a concrete floor that needs leveling, explore Self-leveling Compounds. For wall renovation and surface smoothing solutions, check Wall Putty & Skim Coat. External wall insulation projects can refer to our professional ETICS / EIFS system solutions.
