Hello folks , i have a queery that im sure can be answered on here , in my spray booth i have a terrible chalky concrete floor , the more i sweep the more dust i create , so i was told seal it with pva which i did , great less dust but now i want to paint it to further manage the dust , i rang the paint supply place and the guy said that he thinks the pva will stop the paint from bonding and he couldn't guarentee it would last . Im wondering did anybody on here ever face the same problem
