thanks guys much appreciated
Hi , possible reason for print, leaving an cementisiouse encaustic over night to dry poss not long enough before sealing- i will leave mine 48-72 for a light clean or if restoring min 7 days if you used a solvent based MN moisture will push up the impregnator and will not penetrate as well as a dry tile,did you leave a wet look finish to the tile and let dry in when you sealed it?
If you did you may have slight excess( as the guys said earlier or possible patches, always towel back your impregnators befor working the next section( no wet look)
your hand print went in!!
Possible solution to reactivate contaminated tile- reactivate tile by putting more impregnator on keep wet for 5-6 min clean over every 1-2 mins with a white cleaning pad do not let dry out- if drys add more product . Hopefully the solvent in the Product will melt excess , buff back completely with a white towel to a dry , matt finish (this works if you get the patchy floors too)
If not!!! Strip it , dry it (4-5 days) ,re-impregnate, that should shift it
Cheers hope this may help
