Concrete slab resurfacing

Most of those don’t look deep. You could probably get a container of thin set floor compound and fill the voids. Smooth out with a trowel and let it set. You should be able to lay tile right back over it

Yeah they aren’t very deep. I just want to make sure I do it right. I don’t wanna half arse it and then have unforeseen issues later.

If you’re just putting wood laminate planks over it, just do it as best you can and smooth it out. Roll out your underlay and then laminate over it. Shouldn’t really matter if it’s not perfection

Ardex makes a lot of great products for leveling, covering etc. I just used it on a slab that had glue residue and they make a product just for that. I would def recommend using one of their products on your floor based on your pics.

You probably don’t need to do it, but self leveling cement is what you are looking for. It’s basically very thin cement/ mortar that you pour out and let it ‘self level’. It will also help to make your floor more level as concrete subfloors can be surprisingly not level often times.

I considered a self leveling cement because I’ve used it before but the damage to the surface is so random. I’m really trying to avoid pushing and pulling a self leveler across the good surface. Plus I’m dealing with an area that spans the living room, dining room and kitchen. I don’t want to get caught in a situation where I run short of product or I’m trying to mix a new batch while the old batch has started drying. Just seems like an unnecessary mess. Something I can work in small batches is ideal.
