You can use it as a sealer on any concrete floor, this could be a garage concrete floor or in the household.For more info, check out the ‘ Taping and Jointing‘ section in our guide to plasterboarding brick walls. An important point to make is If the surface you are working on is external and likely to be washed with rain regularly, PVA is not the best product to use.
