glass coating improves the strength and longevity of wooden tubs with an almost imperceptible decrease of aroma

glass coating

We completed the experimental phase of hinoki wood treated with a new glass based product.\n\nThe sample in the picture above has been coated with 2 layers and let dry for 12 hours.\nThis product is isopropyl alcohol based and its effect is semi-permanent.\n\nGenerally, any type of full penetration product silicon based or fluoride based deteriorates overtime and it becomes more permeable to water (and dirt).\nThis product creates a matte glass coating thus it is virtually permanent and does not allow dirt or mold particles to stick to the wood.\nIf used outside, it can be labeled as self cleaning as when it rains also the dirt particles are swept away.\n\nOne downside is that it closes the pores of wood hence the aroma of hinoki is almost completely eliminated (unlike other silicon based products like Kihada ichiban).\n\nWe are going to use this glass based product on the bottom plank (top and bottom side) because it is the most vulnerable as it collects all the tensions coming from the sides.\nIt is also the last surface to dry while the side planks are already contracting.\nThe aroma releasing surface may be reduced by 1/9 but the tub becomes sturdier and more stable.\n\nPlease contact us for any question. -> japan@bartokdesign.com
