Oh and also, can you put a rubbed in traffic wax over a synthetic liquid wax

Short answer no, probably not.

It is usually one or the other I’m afraid, the synthic ‘wax’ will try to precent the real wax from sticking

Hope this helps

OK you may improve the seal with more coats but I suspect that the impregnator is not quite up to the job, not having a go at the brand, it is just that some products work better on some materials and not so ogood on others, also there are two distint ‘markets’ for sealer these days, standard selaers and premium sealers (you can usually tell which is which as the premium are about twice the price).

For a very porouos material like this, a water based impregnator is often the best bet – the solvent ones dive too deep – and the polymers they use are small, so they effectively go in too far to do any good – you need the sealer to stay near the top, to provide a good base layer for the top finish. Sometimes leaving much longer drying times between coats can really help – like over night for example (gives the last coat much longer to form strong bonds and then the subsequent coat is more likely to sit on top and build up, rather than just merge with the previous one.

You say that it was still lettting in water before you applied the top coat, I would not have applied the top coat until I was happy that I had got the sealer right.You are going to have to strip back I fear, take off the top coat (which should be fine in itself as it is designed for the tile), you will need a stripper again for this like the one you used. Then rinse and dry. when really dry, do a water absorption test, if still very porous then you are going to need more sealer – either, try additional coats of the same sealer, leaving a good time betweeen coats, or, if water soaks in readily, try a coat of a premium water based sealer instead.

You will probably find that the stains come out during the stripping, any stubborn ones may need some additional help with a poultice.
hope this helps
