Because it is still a reaction between solvent and oxygen, the drying process is similar. They are more durable than oil varnishes and shellac varnishes. However, polyurethane lacquer provides a tougher, stronger, as well as waterproofer cover.

Additionally, polyurethane sealer is slow to dry out. There is no layering effect similar to varnish, but the same downsides apply. The first coat will show dirt, which can then form on the surface. It may also have blemishes.

Epoxies also tend to be heavier and more dense than PU systems. These are great for taking in impacts and thermal impact. However, epoxies have a lighter alternative and are more space-friendly.

Comparing PU with other substances

While PU may seem like an excellent choice, it is actually not. What they do give in sturdiness, they also lose in flexibility as well as aesthetic appeals. Epoxies can easily be adjusted to suit a variety of environments. Additionally, they are available in a greater range of colours and styles as well as decorative options.
