This can be common with tree species that have naturally soft-wood, particularly Privet\/Ligustrum species.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"left\">A few weeks prior to the re-styling, I carved out the very soft and pulpy wood on the tree, and took the opportunity to improve on my previous work. After staining the deadwood (using the\u00a0ash and lime-sulphur\u00a0technique), I hardened it to stop it rotting again in the future.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"left\">In previous years I have used &#8216;wet-rot hardeners&#8217; to harden deadwood and prevent it rotting. This is often sufficient to ensure that the deadwood remains stable. However, particularly where the deadwood is in continued contact with the soil, some areas can still become very fragile over the years despite the use of wood-hardeners.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"left\">Earlier this year a fellow enthusiast advised me to try using superglue (also known in some countries as Krazy Glue) to harden the wood and the results have been fantastic. I really wish I&#8217;d known about this technique a few years back, as it makes even the weakest, most fragile wood, rock hard.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">Using superglue liquid, not gel, the superglue is applied when the wood is as dry as possible. If necessary, first use a small gas blowtorch to drive out any moisture that remains in the upper layers. The superglue is carefully dripped over the deadwood and it soaks straight in, in the same way that wood hardener does. Keep dripping the superglue into the wood until it becomes glossy showing that the wood is fully saturated (as with wood-hardeners). The superglue takes a short period of time to harden off; it can then be wire-brushed to remove the gloss finish, as necessary.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">Particularly when applying it in a large volumes, use superglue outside, or in a well-ventilated work space. The chemical reaction produced as the glue is exposed to humidity in the air and moisture will produce noxious fumes. Also take care not to stick your hands or fingers together, or to the deadwood itself&#8230;&#8230;..<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">Superglue works by a chemical reaction that occurs when it comes into contact with water or moisture in the wood, or humidity in the air. Use of superglue on wood that is wet or damp on the surface, will cause the glue to harden on just the upper layers and can create a shallow, opaque-white surface. For this reason, if at all possible, I would advise using this technique during the warmer Spring and Summer months while temperatures are 10C or above, and the deadwood is typically drier, allowing the glue to permeate deeper into the wood.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">Although I wouldn&#8217;t advocate getting any glue onto live roots (!) generally-speaking, any run off of surplus glue into the soil , does no harm and its spread is very limited.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><img decoding=\"async\" src=\"http:\/\/bonsai4me.com\/Images\/AT%20Bonsai%20Superglue\/Superglue%20bonsai%20deadwood%20(3).jpg\" alt=\"olive deadwood bonsai hardener\" width=\"672\" height=\"500\" \/><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><em>Deadwood on an Olive bonsai. The wood was first stained until I had achieved the colour I required, before I applied a large amount of superglue to harden it. The wood has not been wire-brushed; although there have been occasions where the superglue has left an unnatural gloss appearance, it seems that this maybe the exception rather than the rule. Note that the liquid superglue does not interfere with the natural appearance of the grain, the minute fissures in this very old yamadori Olive deadwood are still clearly visible, .<\/em><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><img decoding=\"async\" src=\"http:\/\/bonsai4me.com\/Images\/AT%20Bonsai%20Superglue\/Superglue%20bonsai%20deadwood%20(4).jpg\" alt=\"privet deadwood superglue\" width=\"552\" height=\"600\" \/><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><em>Newly carved and stained deadwood on an old Ligustrum\/Privet bonsai that had\u00a0<strong>first<\/strong>\u00a0been hardened with superglue.<\/em><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"left\">The deadwood on this Privet bonsai had become so fragile that ordinarily it would not have been possible to carve it. The sheer force of cutting tools mounted to a carving machine would have ripped the wood apart. However, a prior application of superglue made the wood so strong that I was then able to re-shape it at will, creating very thin and delicate panels of wood.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"left\">I found that with the wood already hardened with glue, the black water-based ink I use to darken the hollows simply ran off the surface of the wood. However, the applications of ash and lime-sulpher still achieved the colours and tones I required. My conclusion here is that although it is preferable to carve and stain the wood before hardening it (with superglue), it is not absolutely essential if circumstances won&#8217;t allow it.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/bonsai4me.com\/Images\/AT%20Bonsai%20Superglue\/Superglue%20bonsai%20deadwood%20(5).jpg\" alt=\"privet deadwood bonsai superglue\" width=\"548\" height=\"500\" \/><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\" align=\"center\"><em>Another carved and stained deadwood piece on a Privet bonsai, newly hardened with superglue.<\/em><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\"><strong>Further general information about Superglue and its use in bonsai<\/strong><\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">While researching about superglue for this article, how it works and any possible toxicity to plants or trees (bonsai), I discovered the following further information and facts about the product:<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">The chemical name for Superglue (or Krazy glue) is Cyanoacrylate. It is an\u00a0acrylic\u00a0resin\u00a0that rapidly\u00a0polymerises\u00a0in the presence of water (specifically\u00a0hydroxide ions). Gel-type superglue products have the addition of silica or even rubber to slow down the curing rate and increase the viscosity of the glue. Personally I would avoid the use of these gel-products as they do not sink into the deadwood as is required for our purposes in bonsai.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">The ability of Cyanoacrylate (superglue) to resist water seems to make it popular with\u00a0marine aquarium\u00a0hobbyists who use it to glue the hard corals\u00a0onto pieces of\u00a0live rock. This seems to illustrate not only its water-resistance, but its safe use around living organisms.<\/p><p>When added to baking soda (sodium bicarbonate), Cyanoacrylate forms a hard, lightweight adhesive filler (baking soda is first used to fill a gap then the adhesive is dropped onto the baking soda). Be aware that the reaction between cyanoacrylate and baking soda is very\u00a0exothermic\u00a0(heat-producing) and also produces noxious vapors.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">Cyanoacrylates, now sold as superglue, krazy glue, Eastman 910, amongst others, were invented in 1942 by Dr. Harry Coover of Kodak Laboratories during experiments to make a special extra-clear plastic suitable for gun sights.<br \/>The use of cyanoacrylate glues in medicine was considered fairly early on. Eastman Kodak and Ethicon began studying whether the glues could be used to hold human tissue together for surgery. and submitted an application to use cyanoacrylate glues to seal wounds. Soon afterwards, superglue found use in Vietnam by the military in order to quickly stem wounds in battle.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Superglue works by a chemical reaction that occurs when it comes into contact with water or moisture in the wood, or humidity in the air.<\/p>\n","protected":false},"author":2,"featured_media":3491,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"footnotes":""},"categories":[7,6,40,1],"tags":[29,50,116,117,81],"master_filter":[16],"type_of_content":[19],"season":[39],"acf":[],"views":754,"_links":{"self":[{"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/posts\/3268"}],"collection":[{"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/comments?post=3268"}],"version-history":[{"count":5,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/posts\/3268\/revisions"}],"predecessor-version":[{"id":3500,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/posts\/3268\/revisions\/3500"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/media\/3491"}],"wp:attachment":[{"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/media?parent=3268"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/categories?post=3268"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/tags?post=3268"},{"taxonomy":"master_filter","embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/master_filter?post=3268"},{"taxonomy":"type_of_content","embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/type_of_content?post=3268"},{"taxonomy":"season","embeddable":true,"href":"https:\/\/bonsai4me.com\/wp-json\/wp\/v2\/season?post=3268"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
