“…However, those processing treatments were only applied in wood drying to prevent drying checks. Kerfing is one pre-drying treatment that consists of cuts along the longitudinal axis, and transversal to both sides of a square post, and it has potential for significant reductions in drying time and warp (Ruddick and Ross 1979;Morrell and Newbill 1986;Rozas and Steinhagen 1996;Mallo et al 2014). Evans et al (2000) applied single and double kerfing, center boring, and incising to green, peeled, slash Korean pine posts to reduce checking in preservative-treatment.…”

To achieve a deeper and more uniform impregnation of water-soluble phosphorous-based fire retardants (WPFRs), in this work several physical pretreatment methods were developed including kerfing, boring, and the combination of both for structural square-wood posts in wooden buildings. Research was performed on three wood species, sugi (Cryptomeria japonica), larch (Larix olgensis), and Douglas fir (Pseudotsuga menziesii Franco), which are generally recognized as refractory wood species. The effects of pretreatment method on chemical uptake, chemical penetration, and mechanical properties were evaluated. The methods were compared with the incising method, a traditional method used for wood preservation. The results indicated that the pretreatments effectively increased the chemical uptake and penetration, especially in larch wood. Although the traditional incising method also increased the chemical uptake, it decreased the modulus of rupture (MOR) and compressive strength. The boring and combined method with a boring diameter less than 12 mm are recommended for WPFR wood impregnation.
