It seems to inherently have the quality of being a repelant to supernatural forces, but to create a barrier it also seems to rely on the force of will and the unyeilding belief of the person using it. This is in line with actual magickal theory used by real world occult practitioners. It could be a plot hole but I don't think it is. It's more likely that the mountain ash barrier requires continuous concentration for it to deflect all attacks by the supernatural, not just the supernatural creature trying to force its body through the barrier. If you rember, in season one, Peter threw a chair a Deaton while he was behind the barrier in the vet clinic and it exploded into about a thousand pieces before it hit him. Either it was actually the barrier or Deaton secretly has telekenetic abilities like Jennifer Blake/Julia Baccari. This gives credit to my theory that Deaton is secretly a bad#$% mother#$%$er. It could be a plot hole, but it could also be that the barrier and its effectiveness is at least partially, if not completely reliant upon the person who laid down the barrier and if they are concentrating.

back in season 1, peter was able to throw a chair past the mountain ash area so its not a plot hole
