How much area does 1 pen cover?

It all depends on how many layers you apply, I did 3. I have used 4 pens for my kitchen which is roughly 12 by 18ft. Hope this helps

Is the touch up considered permanent or semi-permanent or will wash away with cleanings?

Good question. For most grouts it is permanent. However some customers try it on "sealed" grout and it is not able to adhere with the grout, therefore it is temporary.

Will this product fill in fine cracks in the grout? My back splash grout ling that meets my counter top has a small crack line.

If the cracks are VERY fine, the grout pen may fill them, but this does not apply to silicon grouting, which is generally used to seal the line between counter top and wall. The grout pen is meant for mortar grout.

Will this work on painted grout?

Yes GROUT PEN will work over painted grout (unless oil paint was used prior, but that is unlikely). LOOK BRAND NEW: Skip scrubbing tiles and use Grout Pen to paint and recolor your grout for a bright clean appearance USE ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles LONG LASTING INK: Tackle small or large DIY projects with a pen that covers up to 150 feet of thin 2mm grout ADVANCED FORMULA: Non-toxic, water-based ink that covers grubby grout stains making it look brand new again NOTE: Grout Pen may not bond to sealed grout. Test the porosity of the grout with a few drops of water. If the grout does not absorb the water drops within a few minutes, this indicates that the grout was probably sealed.
