pva it the day before to much background causing your problem mix pva 50/50not sure why it happens! Could it be that yesterday was very hot? 26 degrees? I properly pva’ed it and waited until it went tacky, by the time I plasteted that section of the wall the pva would have dried, could that be it?
edit: they little crack marks feel completely smooth, they arent actual cracks they just look like it..
i think it was over watering after applying. I pvaed the walls three or so times the days before and just before plastering. I noticed that ifI wasnt fast enough on big walls the plaster would go off too quick so when I was doing my first and second dry trowel to polish it up, i needed to add water.pva it the day before to much background causing your problem mix pva 50/50
