You’re paying more for trim that’s protected. You should get protection, inside and out, that you can rely on.
LOSP treatment is the most effective protocol for above-ground exterior trim and fascia, with a four-decade track record.
It provides superior rot-resistance and insect-resistance, with wood-stabilizing and water-repellent compounds to reduce movement and checking.
ArmorCore™ has improved over time to include more advanced coatings. The primer is optimized for treated wood, and has greater flexibility from high silicate levels, and greater UV resistance from titanium dioxide, to provide a more durable undercoat for the life of the painting system. It’s designed to be able to remain exposed on a building site for up to 6 months before painting, and is ready to directly topcoat with any high quality exterior paint.
