Polyurethane Primer: How to Choose the Right One for Your Surface and Environment Choosing the right primer is crucial when starting any painting project, especially when dealing with difficult surfaces and various environmental conditions. Polyurethane primers have gained popularity due to their versatility and durability. In this guide, we explore the key factors to consider when choosing a primer, focusing on achieving optimal results for different surfaces and environments.
Surface types are important: Before diving into plotting, assess the surface you are working with. Primers for metal surfaces are different from primers for wood or plastic. Polyurethane undercoats are known for their adhesion to a variety of materials, but choosing the right formula ensures optimal adhesion and longevity. Consider environmental conditions: The environment in which the painted surface remains plays a decisive role. If the project concerns, for example, outdoor use, the primer must withstand UV radiation, temperature fluctuations and humidity. Internal projects may have different requirements.
