Amine Blush.. because I'm anal

Making sure I have this right .. take a spray bottle such as an empty Windex spray bottle.. fill with clear, no soap, or anything .. water.
After the epoxy has dryed .. spray the surface with the spray bottle or plain water and scrub the surface with a scotch brite pad ..

After scrubbing .. dry off with towel..

Now.. I can sand, and later paint .. right?

It's as simple as that. It doesn't take much.

For your own reference, note what the surface looks like before you wash, and then later after it's washed and dried. There's a clear difference in appearance.

as simple as that, as Tim says. Or you can use a bucket of water and a scrubber, then just wipe it down dry.

It's really not the bugaboo people make it out to be.

If you run your hand over the cured epoxy you will feel a film that is quite oily. It will seem that only soap will remove it, and for years I insisted soap was necessary. Well it isn't, it is as easy as your description.

The Gougeon's used to call for ammonia water. They have dropped the ammonia part now-

Here's the information direct from the source.

www.westsystem.com wrote:Cured epoxy-Amine blush can appear as a wax-like film on cured epoxy surfaces. It is a by-product of the curing process and may be more noticeable in cool, moist conditions. Amine blush can clog sandpaper and inhibit subsequent bonding, but it can easily be removed. It's a good idea to assume it has formed on any cured epoxy surface.

To remove the blush, wash the surface with clean water (not solvent) and an abrasive pad, such as Scotch-brite(TM) 7447 General Purpose Hand Pads. Dry the surface with paper towels to remove the dissolved blush before it dries on the surface. Sand any remaining glossy areas with 80-grit sandpaper. Wet-sanding will also remove the amine blush. If a release fabric is applied over the surface of fresh epoxy, amine blush will be removed when the release fabric is peeled from the cured epoxy and no additional sanding is required.
