Ironwax is only for natural stone. It requires a slightyly porous tile to key onto. So if you have a ceramic or porcelain slate effect with an impervious surface, it won't adhere properly. You will need to strip the floor with LTP powerstripper, and if you still want the "just mopped" look, the one you need is the LTP Glaze Protector. That, you can apply up to 6 coats depending on how shiny you want it.
For every day cleaning on any tile that has been sealed you must use pH Neutral cleaners, such as LTP Waxwash, which will clean an keep you sealer topped up (as it contains a trace of linseed oil). "Off the shelf" cleaners are too aggressive and will cause sealer to break down and lift.
