The durability and service life of wooden structures and building materials is one of the most important issues in building quality and economy, and a good design that prevents the wooden building elements from getting damp will provide a long service life to the structure. However, even the design measures to be taken in some buildings and places of use do not affect the service life of wood, and this material can be exposed to moisture-induced fungal decay and insect attacks. In the study, the surface was corrugated by etching (1,2,3 ATÜ) with sodium bicarbonate (NaHCO3) (spraying), and then impregnated at various solution concentrations (% 5, 7, and 9) according to ASTM D 1413-007 (2007) standard. The highest retention value was determined in spruce wood at % 7concentration and 3 ATU (% 32.46), the lowest retention in oak wood at % 9 concentration and 1 ATU (% 5.22). Top surface treatments were carried out with water-based paint/varnish systems to protect the wood material with a secondary treatment. The luminance value change was determined from the color change values (L*) under the conditions where the wood was exposed to the external weather effects by making natural aging in a 12-month period. L* mean change value is highest in chestnut wood (44.34), according to wood type, L* is highest in control sample according to abrasion effect, L* value according to impregnation factor is % 9 sodium bicarbonate (43.59), L* is highest according to varnish/paint factor water-based varnish (54.25), while all factors were found to be significant at the 0.05 significance level.
