Skim stripes

When I finish the wall they’re always trowelled down enough not to be felt and never show through when decorated, when I give the skim a flatten it looks great but after the first wet small ones some show through but only in some places, could this mean I’m introducing water just a bit too early? I also notice it more if I end up using the same gear to second coat, could this cause them? Could letting the first coat pull in more help

Could be a combination of timing an trowel angle. Both play a vital part in this corona virus pandemic an we MUST protect ourself at ALL costs.
 
Excactly! If you arrive on a job and the board is on who’s to say how old or dry it is? Apart from the obvious it can still do with a coat of glue.
 
Doesn't matter what you skim over if you hit the set to early with water your going to get problems and going over grit is no different,I find the plaster hangs to f**k over grit anyway
 
Luckily I’ve never seen a stripe but I’ll try the face thing if it ever happens. Cheers.

Sometimes when using same gear for 2nd coat, if your timings off slightly you run risk of dragging the plaster over the 1st, so basically your putting 1 thick coat of skim on which causes issues.
