getting nitromors off tiles

[marcATS]

Laid black porcelain tiles but grey grout won't come off surface and groves. Grout manufacturer advised Nitromors to remove it and now we can't get rid of the oily residue from over use of Nitromors. Any suggestions? Been scrubbing and buffing for 4 days!

hi sounds like you need a degreaser to remove shipping wax whats nitromors///////////

[marcATS]

any suggestions on what? washing up liquid? it's a huge floor

[jay]

hi degreaser is a product designed to remove wax from porc tiles iys not washing det

Nitromors........bloody hell.

Heavy duty paint stripper could do more harm than good. Your'll need to neutralise the paint stripper with plenty of water and a bit of vinegar.

Then if still grout haze.......use a haze remover from any good tile shop

[marcATS]

The grout used was Bal microflex, because of the anti-bacterial agents built within makes it damned difficult to remove. Mainly because it fights and protects against acid attack.. what next?

[Dave]

Who told you to use nitromors...?..

[marcATS]

Believe it or not bal tech services. stunned me also.

[Dave]

I'm really surprised you haven't etched the tiles...

Nitromors.......oHH!! thats made me laff....not at you but that advise...

You need to nuetrilise it now...before you can seal them...

[Dan]

What are BAL saying when you call them now then?

[marcATS]

it's had more water thrown on it than anything else, gone over it with a floor buffer.. removal is slow and painful.. wonder if pro clean would be man enough.??

Scary.... Nitromors??? Someone having a larrf!?

I take it they suggested using nitromors to separate the polymer & microban from the cement? It is also something that you need to do with ultracolor plus to separate the polymers. Otherwise any acid cleaners fail to work effectively.

Nitromors turns opaque when in contact with water, if what you have left is not opaque, smeary phlegm looking stuff then I'd doubt it was remaining nitromors, more loosened grout polymers or slurry residue from the factory wax used on porcelain that have been partially disolved by the nitromors.

Pretty much any alkaline cleaner should tackle the wax, you could try calling someone like LTP who might be able to point you in the right direction.

[doug boardley]

they probably suggested that you lick the surplus off

An old thread I know but I've just come off the phone to Mapei technical who also advised Nitromores. The problem is haze on the grout itself, and techy man said that prior to using Mapei Keranet acidic cleaner, I should use Nitromores to break down the polymers which would prevent the Keranet absorbing.

I was a bit worried so looked on here and hey presto Bal are advising the same thing.

Despite what others may laugh at, I've used Nitromorse on a number of revitalise jobs with outstanding results.
If you follow the instructions, do small areas at one time and do not leave it to dry on the surface, it is one of the most effective cleaners I've come across.
Having said that - I'd only consider using this product having tested it first on a sample area of tile.
There are many proprietry 'cleaners' on the market that do not do what it says on the tin - this does.

just read the whole thread through

if you are going to use paint stripper trial test a small area out off sight first to ensure the stripper wont damage the tile. the new generation of strippers are non caustic and shouldnt etch but depending on the tile it may affect the colour

I'm going to give it a go - but first on an offcut and will observe verty closely. A scary prospect using paint stripper but that's what Mr Mapei says.
