Paulownia offers excellent dimensional stability due to its engineered core which greatly reduces the possibility of warping. Paulownia’s fine grain texture, knot free appearance and low oil content make it the perfect timer to be stained or painted.
In terms of durability, Paulownia although classified as a Hardwood by nature, is slightly softer than Basswood. To compensate for this we treat it with a Gesso coating (acrylic polymer base) prior to going through the painting process, adding rigidity and longevity.
