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?
