Can I use a hot glue to cover a PCB board to insulate it and prevent it from damage?

I want to DIY PCB board at home, but raw material is limited. Can I hot glue to cover a PCB board? Is it advisable to do that?

Not recommend. There are two proper methods to coat a PCB.

The first is via a conformal coating.
The other is potting epoxy.

Depending on your electronics casework, you may be able to fill with with non-conductive epoxy.
You have to be concerned about any cabling.
Once potted, your gear is unrepairable. You have to watch out for connectors.
If they will with epoxy, they won’t work any longer.
If the PCB is depending on cooling via the case, you can try heat-conducting, electrically insulating potting epoxy.

Why does the PCB manufacturer always ask for a change in your PCB design?

Many a time our PCBA manufacturer calls us about a problem of the design file. Sometimes we think it is time-consuming to discuss this issue. Just want to know why they always do that.

Is paste mask layer, both top and bottom layer, necessary for THT components?

I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
