Exposed levelling product

I want to use a levelling product (e.g. ardex) on my laundry floor which is a concrete subfloor which has previously been tiled. Is it possible to seal the levelling product and leave the laundry floor as a polished concrete, or are the levelling products designed to only be used under a new floor such as tiles? Also, is there a minimum thickness I can lay the leveller? Do I need to raise the waste that is in the middle of the floor? (Sorry if these questions seem pretty basic - first time renovator!)

I have done what you are proposing and was fairly happy with the outcome. I had the Ardit applied by a professional as it does require some skill. It was then sealed to give a polished concrete appearance - though obviously without any aggregate it looks very 'flat'. Ours was about 10mm thick over a very rough concrete slab.

You will get colour variations between batches and we also had several hairline cracks. No big deal but don't expect a 100% perfect finish.

Good luck.

hardit is a bit hard to manouvre and it wants to level itself out, hence the name floor leveler, so if you dont need falls then yes it is possible, you just have to go around the room and block off any holes trough witch it will escape and block them, or youll find the hardit will dissapear through them.

dont forget to prime, othersise it wont adhere properly, and sont over wet because it wil become weak and crack, delaminate and fall out.

Levelcrete comes in different build height formulas. You can purchase 1mm to what ever.
