Discuss Concrete subfloor leveling issue in the DIY Tiling Forum area at TilersForums.com.

Hi -

I ripped up laminate flooring on a concrete subfloor. It was my first DIY project and instead of using mortar to even out any glue that was stuck on or sand off, I used a thin layer of self leveler. I mixed it correctly but for some reason still wasn’t level so I tried grinding it with an angle grinder attachment. Made it worse. Poured again. Also made it worse.

I ripped out the existing vanity as seen in the image and there’s now 1/4 inch from vanity bottom to new subfloor with concrete.

My question is:

If I try to fix one last time, should I try to sand down to Original subfloor and hopefully attach whatever I’m using to a shop vac for dust?

Do I do another pour to level up to the 1/4 inch and sand the existing pours down a bit then pour again?

Even with a laser level it’s very hard to tell where slight dips or rigids are so it’s almost impossible for me to sand my hand down to flat,

Other option… should I just hire someone for this? And how much do you think it would cost? (Trying to save $)

What are you trying to achieve ?, sounds like your preping for karndean or similar ?
You want it like glass ?
Get a trowel and feel for lumps or dips or use your eyes ,pouring is the problem , laser levels sounds a bit technical , straight edge look underneath it for gaps or find lumps
