CoverSeal AC250 is a hard surface sealer. So it’s useful where you have concrete – either polished or unpolished – or where you’ve got terrazzo or natural stone.

In a commercial environment that could be:

• A restaurant
• The entranceway to commercial buildings
• A warehouse
• A workshop
• • A grocery store
   

There’s a number of issues you’ll find with acrylic sealers that you can purchase from a D.I.Y. outlet or a big box store.

Firstly, not all are stain-resistant.
Those that possess some semblance of resistance to stains provide only weak, temporary levels of protection. More specifically, they don’t “hold out” stains for very long. In some cases, there are only a few hours before stains penetrate through their barrier, and start setting into the underlying surface.

Secondly, they don’t provide good water resistance.
We often hear complaints from first-time customers about their previous use of those products. They cite product failures like water-marks, skid marks, and other signs of wear and tear showing up shortly after application. A typical example is if you leave a damp mop or cloth, or you spill water on the floor, you start seeing watermarks shortly.

The third issue is the inability of store-bought sealers to bond to smooth and polished surfaces.
Due to their inferior formulations, they require a lot of surface prep to perform well.

And the fourth issue is about the UV resistance of these products.
Due to poor ingredients and low-quality formulations, they can’t handle UV exposure very well. This means they can’t be used outside.
