Well , after going through two heavyduty trash bags no nozzles , just filled a bottomcorner with mortar , tightened it closed and then cut a hole to squeeze through , it held up surprisingly well ! ! However , the section that I did with that a smaller section than my 1 st still has very significant hazing , I mean I got the mortar in place pretty well with that bag but just in the act of wiping it up , it spreads haze I cannot get them 100 % clean should I be using a TON of rags ? I ' m just using 4 rags and a bucket of water , maybe that ' s insufficient Am gonna have to get muriatic before going much further because I ' m afraid of ending up with a job 3 X as long due to hazeremoval On the subject of application bags though , I won ' t be using a trash bag my next session because I went to a dollar store and grabbed some cakedecoration bags , they ' ve already got plastic nipples and seem perfect am thinking that wiping bricks down with wet mortar in their vicinity is a nogo off the bat , my intention is to try and finish without missing a grout line , so hopefully the new cakedecorating bags are precise enough to allow me this ! The trash bags were very precise compared to using a trowel , but not so precise that I could get it in just the cracks wo touching the upperedges of the bricks , at least here there
