Joiners/ Carpenters and all DIY fanatics use it for many purposes with many companies making strong strains of the stuff. However, Plasterers use it for different reasons. Concrete has a high porosity which can be a problem when deciding how exactly to seal the floor. This high porosity means that paint doesn’t adhere correctly to the floor and seeps into the concrete giving you a blotchy, streaky concrete floor.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.
