Most Vandex products are based on high-quality Portland cement and fine-grained sand. Chemical additives provide special properties such as waterproofing, excellent processability and more. All products are continuously subjected to continuous quality control.
Vandex applications form a solid chemical compound with the existing concrete. The physical and chemical interaction does not negatively affect the concrete. On the contrary: a Vandex treatment prevents the ingress of water, reduces the vapor permeability and increases the (chemical) resistance of the concrete.
Cementitious products need curing to fully develop their properties. The water should react with the cement and should not evaporate too quickly. This leaves pores and can cause cracking in the coating. In general, Vandex coatings should be kept moist for 5 days. For product-specific details, please refer to the application guidelines.
