Crown Trade PX4 All Purpose Primer. A water-based primer for interior and exterior use. Seals and stabilises dry alkali surfaces like lime plaster, cement, and concrete. Superb adhesion to materials such as glass, ceramics, and hard plastics, previously painted surfaces, as well as most wood and non-ferrous metals, while securing the substrate against powdering and chalking. With exceptional stain-sealing capabilities, it's the go-to choice for surfaces stained by smoke, crayons, tannins, water stains, and aerosols.
