Polyurethane bitumen coating is among the commonly used materials in construction and building projects. As a material providing waterproofing, bitumen-based polyurethane coating is frequently preferred for insulation and covering processes. Due to its advantages such as waterproofing, durability, and chemical resistance, this coating is an excellent alternative for roofs, terraces, and floors.
Derived from combining two different chemical substances, bitumen-based liquid polyurethane coating ensures impeccable waterproofing due to its flexible and durable structure. Polyurethane bitumen coating also provides resistance against water leakage, cracking, and chemical effects, contributing to the long-term preservation of the surface.
How is the Application of Polyurethane Bitumen Coating Done?
Polyurethane bitumen coating is preferred in waterproofing and surface protection projects. This coating material is obtained by combining bitumen, which stands out with its waterproofing and adhesion properties, with polyurethane, which provides additional durability, flexibility, and chemical resistance. When applied by expert teams in the field of polyurethane bitumen coating, it can be used for an extended period.
Surface preparation should be carried out before the application of floor coating. To prepare the surface for polyurethane bitumen coating, the surface must be cleaned and sandblasted, and any cracks or damages should be repaired. To ensure the perfect adhesion of bitumen polyurethane material to the surface, a primer application, which is the pre-layer, is performed before the application. The primer application may vary depending on the surface type and conditions.
Bitumen coating can be applied to the surface either hot or cold. For hot application, the bitumen needs to be melted and spread onto the surface with a roller while it is hot. Cold application, on the other hand, can be carried out with an adhesive. Once the bitumen coating application is completed, the polyurethane coating can be applied. The polyurethane coating material is poured onto the bitumen material and spread with appropriate equipment, ensuring excellent waterproofing of the surface.
After the coating application is completed, the surface should be allowed to dry and harden completely. The drying time may vary depending on the application temperature and humidity levels.
Being careful during the polyurethane bitumen coating ensures long-term and effective results. Seeking support from professional teams can be beneficial for the correct application of polyurethane bitumen coating.
