Description If is a double-component, polyurethane-bitumen based, cold-applied, self-levelling dilatation and joint filler with high mechanical and chemical strength Usage Areas It is used for waterproofing and filling horizontal dynamic dilatations and joints. Advantages It is elastic. It maintains its elasticity between -20°C and +120°C. It is a cold-applied material. It is resistant to abrasion. As a self-levelling material, it is applied easily and quickly. It has very high adherence to the surface if is applied. It is very durable Application The surface to be treated must be clean and dry. The joints must be cleaned with a wire brush, spiral engine or sandblasting. If possible joint spacing must be treated with compressed air. DDM 2K applied onto damp surfaces results in foaming. It is used only on horizontal joints. All the hardener contained in the small pail is mixed with all the main material contained in the big pail by using a low speed mixer until it becomes homogenous. The mixture has to be consumed within 30 minutes. Otherwise gelling occurs and it cannot be recovered. After the application the surface must be protected from water exposure for at least 6-8 hours.
