LTP colour intensifier residue removal.

[chuckles]

Have recently been asked to clean up a terracotta floor that has had LTP colour intensifier over applied and now there is a horrible grey shiny bloom on alot of the tiles. I've used 8 to 1 mix of LTP power stripper which didn't remove the bloom and then a stronger mix of 1 to 4. But that still hasn't worked. Any recommendations on what I can use to remove it? White spirit perhaps. At my wits end. The floor is newly laid and had one coat of sealant on it before the LTP colour intensifier was applied about a week later. Have phoned LTP and they've just advised to use the power stripper which hasn't worked.
Any advice gratefully received!

What sealer was applied first..?.. you normally use colour enhancer first...

Hi. Sorry for the delay. Been trying to find out exactly but no luck. All I know is that it was an LTP sealer used and as the finish is matt I presume it's the mattstone that was used. Any advice? Thankyou in advance.

From what I can gather the sealer was LTP mattstone. Any advice greatly received!

If mattstone was applied first then it was done backside first.... you will not get full colour enhancement that way..

Try the white spirit on a small inconspicuous area but i will say that colour enhancer is hard to remove once hardened ..

If that doesn't work then you could try ltp solvex...

Ah. OK. The information has slightly changed in that i now know that the sealer was in fact Fila natural stone sealant and not LTP mattstone. I dunno if these are similar but apparently sometimes the sealers are either water based or solvent based and that can make a difference.
