There are a number of purposes behind residential and commercial surface coatings.
If you have a raw surface that has no protection, it is going to wear down faster. It is going to look dull faster than it should. It may also be unable to deal with the abuses that it goes through.
It is the wear and tear that a floor or other surface goes through that determines the coating it needs. For instance, a garage floor coating is going to need something much different than the coating in a banquet hall. Another example is how the floors in an office building will need something much different than the floors in a warehouse.
Surfaces with a lot of foot traffic are going to need something different than a surface that is driven on. And then you have those surfaces where people may spill substances, so there needs to be a coating that can still create traction when it is wet.
The list could go on and on.
But there are three things that coatings can do for the surfaces themselves. The first is improving the appearance of the old surface. That dull surface can be turned into something illuminating.
The second is protecting the surface. As stated earlier, an unprotected surface is going to dull quickly. When it is protected, it doesn’t have to take the impact of the many abuses inflicted on it like it would without that protective barrier between it and the object doing the impacting.
The surface can also be protected from the aging process. Because you want the surface in question to last as long as possible, you need to protect it. Protecting it means not having to replace it before its time, resulting in money saved on premature replacement.
Surfaces become more beautiful, safer, and they become stronger.
