Adhesion problems in the hot bed


Hi Guys, I have an adhesion problem since the supports and sometimes with small figures, these detach from the heated bed.

I have followed the tutorials and I have adjusted the bed with a thin paper (such as ballot paper, thermal) so that it has a better friction than the A4 sheet, but even so in large figures they come off almost at the end or the impression does not remain partner.

I already tried with lacquer, putting the hot bed, hotter, but without success, now I was thinking of changing the cover, putting one of those textured (metallic) ones or some LokBuild that I brought a long time ago, what I don’t know is if the cover can be peeled off (with a hot gun for example) without damaging the bed or its heating function.

Any experience with the change? any tutorial that exists? Any help is welcome.
