What are the drying times of epoxy seal coats and flood coats?

Drying time of an epoxy seal coat:

• 4 to 10 hours is optimal. However, you can wait as long as you'd like to apply the flood coat, with no sanding required.

Drying time of an epoxy flood coat:

• If you're recoating within a 4-to-10 hour window, no surface preparation is needed. The layers will bond together as one.
• If ten hours have passed, you will need to lightly scuff the surface with 220 or 320 grit sandpaper.

After scuffing, you should wipe off the surface using a clean rag with denatured alcohol or acetone.

Do not use paint thinner (mineral spirits).

• The wipe down process with the solvent should be done with a clean rag that will not leave any lint on the surface.
• Continue cleaning until all sanding dust has been completely removed.
• You are now ready to re-coat. Don’t worry about the sanding scratches, as the next pour will fill in the scratches and restore its clean, clear, glasslike appearance.

Caution: DO NOT USE A TACK CLOTH. Tack cloths will leave oil on the surface, causing the epoxy not to bond properly and likely creating fisheye blemishes.
