hi,

whats the best tool to remove dried grout haze on trav and slate, these tiles have been inpregnated?
Any tips?

Paul

Impregnated before or after grouting.?

lithofin cement away 1:1 with water will work, but you will need to seal after (at least 24hrs later of course) as the acid will break down the original seal.

its not bad, if you know what to do!
cement away breaks down the haze and the clumps of grout, afterwards you are left with a RAW surface, hence the reseal after the water has dried out!

wear gloves, apply, leave 40-50 mins,use tool to remove stubbon bits, sponge, dilute, sponge, washboy wash, leave 24-48hrs, seal.

Job done.. and dont do it again!
clean up after yourself you messy pup!

Before you attack it with acid cleaners. i would go over the floor with a scotch pad and Aquamix grout haze clean up..

There is no need to strip sealers if haze is just easily removed .

Aqua Mix Grout Haze Clean-Up is a safe and effective concentrated cleaner that is added to the grout cleanup water for removal of cementitious grout haze and latex additive film from tile during the grout cleanup process. It may also be used full-strength to remove light grout residue within the first 10 days after grouting.

was the stone fixed with rapid se adhesive????. i have seen slate that was fixed with slow set and salts had bled through to the surface . hope its not that

I wouldn't use an acid on Travertine!

And if you leave it on for 40-50 minutes

I had this same thing happen to me on a recent tumbled travertine mosaic bathroom I did.
I couldn't believe how much grout the walls took, and even though I kept washboying as I went along, I ended up with a quite bad misty smear over the tiles.

I used a "grout residue removal" solution. I mixed it up to the most concentrated, and used a cheapo plastic scouring pad scrunchy type thing to agitate the surface.
I left it one for 10 minutes, then rinsed it off with clean water.

And yes, you will need to seal again after this, it brought the colours of the tiles right out and looked awesome once done.
It takes alot of effort, but its the best way to go and don't worry, it can be fixed!!!!
