Greasy marks when sealing - transit wax?

[t0m]

We have had 4 square meters of polished porcelain tiles laid in our bathroom. These ones from Homebase. The Website says they need sealing so I bought some LTP MPG sealer and applied it as per the instructions. When buffing, the surface turns to greasy, smeary mess - the transit wax problem?

My question is, how do I tell if there is transit wax? There doesn't seem to be any evidence of it on the tiles as they came out of the box.

I have scrubbed off the MPG and tried HG Power Cleaner to remove the wax on the advice of a local tile supply shop. I applied it liberally, undiluted, but after plenty of agitation using a green scouring pad there is no discernible difference between the laid tiles and those fresh out of the box. Should I be able to tell when the wax is gone?
I tested more MPG on the Power Cleaned tiles and the same greasy, smeary marks appear when buffing.

do the greasy smear marks dry away, any photos?
When you are sealing these,do you remove all excess-are you leaving a slight wetting to dry in?
do a single test tile, keep wet for the suggested saturation, take a white old towel and buff completely dry after this saturation. turn the towel and keep buffing- do not leave a wet look finish to dry in ,completely buff dry!! try this and let us know how you get on.

Thanks for your reply, Lithofin BOB.

On my first attempt I used lint-free cloths and then kitchen roll to buff/remove excess. The marks were still there after several hours and I didn't want to risk them drying in permanently so I scrubbed the sealer off.

I've just had a test run on an offcut tile which has previously been cleaned with HG Power Cleaner. I followed your instructions, this time applying MPG much more sparingly. I gave it 15 minutes and then buffed for quite a while using both sides of an old white towel. The marks are less visible this time but definitely still there. I have attached some photos (sorry they are not very good - it is very difficult to photograph the marks).

I will leave this offcut tile to dry for 24 hours to see how it looks. Do you think the marks will dry away?

Can anyone answer my original question of if you should be able to tell when there is transit wax present?

I would get some methylated spirits on there with a microfibre cloth, and give them a few good washes with the spirits. That would shift any transit wax. 4th time; just buff with a clean microfibre and see if they come clean.

Just to be clear: the marks are there after I apply the sealer and buff it dry.
Before I apply the sealer there are no marks on the tiles.

Any excess that hasn't been absorbed by the tile will appear as a residue. I'm not familiar with mg as a sealer. Does it smell like naptha/petroleum?

It's LTP MPG, here's the Website. It smells like white spirits!

Naptha based so will definitely leave oily marks. You'll have to polish and buff like mad!
Personally i prefer to use a solvent based sealer such as universeal rapid all in 1. No residue to worry about.

Transit waxes are generally seen as a smear to start with .

I don't think they will dry away, you need to buff the tile back to the polished finish straight after the saturation, as above try buffing harder.

Better than smelling like teen spirit
