Hi All,

i had poured out a self-leveling compound usable for 1-15 mm. i had poured out a layer at about 5 mm thickness and poured it out in 3 times/buckets. These batches you can’t recognize in the finished floor. Everything looked Ok, but it dried up with nasty patches. i probably used too less primer. (i’m not sure. i did apply it length&width-wise )

That patch after sanding, (click to enlarge)

  • (i sanded manually using a brick, then finished it with a electric-hand-sander with P60-pad) now it has less bumps, but still some ridges :/

So my questions are:

  • Does anyone have a tip how to fix it/make it smooth? (i want to add an epoxy-layer as finish)
  • Any idea why it dried up like it did?

    I know absolutly nothing about concert, but maybe if you mâle it a bit rugged then pour some more concrete it could close those gaps. A bit more sanding and your done.

      Hi, thanks for replying.

      i ended up using “Fine floor repair compound” or “cement-based skim coat”, which is a fine-grain, cement-based floor repair paste for filling small holes and surface imperfections before finishing. (as per ChatGPT recommendations )

      it was easy to apply and smear out.

      i’m planning to sand it with a ‘numatic woodboy’, tomorrow. (As per Epoxy Concrete coating instruction)
