Crown Trade’s new high performance all-purpose PX primer range has been specifically developed to achieve excellent opacity and adhesion on a wide range of surfaces, including tiles and ceramics, as well as helping to block stains and offer protection from alkaline attack. The new range offers a choice between the traditional solvent-based stain-blocking PX3 primer and the new water-based PX4, which also features a quick-drying and low-odour finish.Both the new PX3 and PX4 primers can be used on a wide range of internal and external substrates. Offering excellent wet and dry adhesion, the new primers, say Crown, can be used in tiled bathroom and kitchen areas as they provide a hardwearing coating that won’t peel or blister when exposed to water. They can also be applied on newly plastered walls and masonryas both products can seal porous surfaces and help prevent damage caused by a high alkaline content.
Depending on the condition of the surface being primed, the new PX4 water-based primer can offer significantly reduced drying times, with the potential to be touch dry in just 30 minutes and recoatable in one hour.
The PX4 water-based primer also benefits from an innovative polymer that effectively ‘locks’ stains away into the primer layer so even the most stubborn marks and discolorations can be painted over. When used in conjunction with an appropriate fungicidal wash, both the PX3 and PX4 primers can also effectively prevent stains caused by mould and mildew from reappearing.
