spackling is frustrating

i havnt spackled much. I am spackling a room now. My question is after the first coat other then using the spackle knife to scrap off the chunks, do i sand in between each coat. Or just sand after the 3rd coat?.. i was told after each coat i could just wipe down with a damp cloth. What do you guys recommend.

OK, so you actually mean joint compound and not spackle, right?

If so, you only sand after the final coat but you may need to knock down the occasional ridge or bump with your knife before then. If not, you're using the wrong product for the job and should switch.

A lot depends on how well you apply the j/c. Normally the final coat is the only coat that gets sanded but IF the j/c is applied poorly [humps and dips] it might need sanding sooner. Always use a sanding pole or any device that holds the sandpaper flat. Just folding the paper and using your hand tends to follow the dips instead of leveling them out. Don't sand into the paper - add more j/c if you have to sand that deep.

Rubbing with a damp cloth may be all you need but I'm not sure if that's done on full walls. If you're just patching an area, you may not need to sand at all.

Actually a damp sponge works better. Basically what you are doing is rewetting the j/c and smoothing it out. A flat sponge is easier to control than a rag which might remove/move the j/c unevenly.

Most beginners have to sand between coats because they put they make the compound too thick. I wet the tape first, so the compound slides on easy & thin. That way I don't feel like I'm trying to pull a garbage truck, down the block. You will still see some of the tape. Let it dry. Then the next two coats, use a wider putty knife. Finally, use a wet sponge instead of sand paper.
