Never been a fan of plastic trowels.. however , I have some major pain in my elbow and wrist ( tennis elbow ) so today I trowelled up with a foam back plazi, to see if it would help my elbow.. amazing really, because of less effort required my elbow wasnt too bad, and it finished very nice, over pva/skim... so anyone suffering with this, I would defo recommend the plazi to trowel up...
