Excellent finish and protection
The epoxy topcoat paint works very well. It seals and protects the surface, leaving a uniform and long-lasting shine.

Great paint
Bought 2 quart (32 flo oz) of white undercoat epoxy paint for my floor project. Easy to work with and great product. I used a 2 part sealer from Epodex to seal and protect the floor.

Effective epoxy undercoat
Although you can add dyes / pigment to your epoxy, there is always a chance that underlying blemishes will show through. The advantage of this preparation is that it very effectively prevents 'bleed through' of such marks. This was my primary reason for buying the product and it works really well. Adhesion of the epoxy is excellent and creates a good transition between the epoxy and whatever underlying material you are coating. That said, if you have a uniform color, unblemished surface, this may be overkill. Personally though it gives peace of mind on expensive installations.
