<p>Crown Trade PX4 is a stain-blocking, all-purpose primer specifically developed to achieve excellent adhesion, even on tricky surfaces.</p>

<p>It can be used on lots of interior and exterior surfaces such as glass, ceramic times, melamine and previously painted surfaces, as well as most wood and nonferrous metals, but not for use on walls (see <a title="Crown Trade Alkali Resisting Sealer" href="../../../p/crown-trade-alkali-resisting-sealer">Crown Trade Alkali Resisting Sealer</a>).</p>
