Removing sealer from microtopping

I used a white base because I was going by Colormakers charts and I made small samples and the samples and overall product didn't match at all. I put two coats of sealer on and now I'm at a loss on how to strip two coats of sealer, restain with a darker color and then reaply sealer. Any suggestions?

I use Colormaker products and have found that before staining Pentimento you should sand it lightly with 100 grit sandpaper. The amount of polymer residue on the surface of the Pentimento impedes penetration of the stain. Usually any polymer topping requires a light sanding before staining to open it up unless you sell the "look" of the lighter areas as a unique treatment.

As long as absolutely every step in your process is completely clean it will work. The solvent punches through, turns your topping into goo and then sets up as one layer. A little risky with multi layer systems. If you used an epoxy, get out he diamond cup wheel and start over,sorry. If it was a solvent, try a solvent carried dye or pigment and reseal with solvent. It works in a pinch

BUT.. over the next day or two.. the Micro Topping should harden back up and turn rock hard since it is impregnated with Acrylic Sealer.. at least that is our experience...

I found timing was the most important factor if left on to long it would eat into the micro topping and neutralizing is important.Good luck.
