Surface treatment

  • Wooden parts are gone through by hand before priming and another time before the actual painting to ensure a high quality surface treatment in our products.
  • As a primer we use solvent thinnable, double component polyurethane paint, which increases the protection against fiber ascendance and pitch staining compared to water thinnable paint.
  • Products are painted in parts, so there is paint also on the surfaces that are left inside corners. We also paint the spaces for lock counterparts.
