When done correctly with the right media at appropriate pressure, blasting opens the wood grain, removes contamination, and leaves a clean surface that accepts new stain or paint more uniformly and deeply than any other preparation method.<\/p>\n<p>The key to successful wood blasting is media selection: wood&#8217;s Janka hardness ranges from 450 lbf (western red cedar) to 1,360 lbf (white oak), but even the hardest common wood species are dramatically softer than any mineral abrasive. The appropriate abrasives for wood are soft organic media \u2014 walnut shell, corn cob \u2014 that remove surface contamination and grey fibres without excessive fibre raising, grain crushing, or dimensional removal of the wood substrate itself.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-media\">\n<h2 class=\"hlh-cl-h2\" id=\"hlh-cl-media\">Media Selection for Wood Blasting<\/h2>\n<div class=\"hlh-cl-table-wrap\"><table class=\"hlh-cl-table\">\n<thead><tr><th>Application<\/th><th>Recommended Media<\/th><th>Grit\/Grade<\/th><th>Max Pressure<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Log home exterior cleaning<\/td><td>Walnut shell or corn cob<\/td><td>Coarse (8\u201320 mesh)<\/td><td>60\u201380 psi<\/td><\/tr>\n<tr><td>Deck boards (softwood)<\/td><td>Walnut shell<\/td><td>Medium (20\u201340 mesh)<\/td><td>40\u201360 psi<\/td><\/tr>\n<tr><td>Deck boards (hardwood)<\/td><td>Walnut shell<\/td><td>Medium-coarse (16\u201330 mesh)<\/td><td>50\u201370 psi<\/td><\/tr>\n<tr><td>Old paint removal (wood)<\/td><td>Walnut shell coarse + plastic media<\/td><td>Coarse \/ Type III<\/td><td>50\u201370 psi<\/td><\/tr>\n<tr><td>Furniture (fine hardwood)<\/td><td>Walnut shell fine or corn cob<\/td><td>Fine (40\u201380 mesh)<\/td><td>30\u201350 psi<\/td><\/tr>\n<tr><td>Wood siding (painted)<\/td><td>Walnut shell medium<\/td><td>Medium (20\u201340 mesh)<\/td><td>40\u201360 psi<\/td><\/tr>\n<\/tbody>\n<\/table><\/div>\n<p>Mineral abrasives (aluminum oxide, garnet, silicon carbide) must not be used on wood \u2014 their hardness will aggressively erode wood fibres, leaving a fibrous, raised surface that requires extensive sanding correction and makes uniform stain absorption impossible. For the full walnut shell technical guide, see <a href=\"https:\/\/hlh-js.com\/resource\/blog\/walnut-shell-blasting-abrasive\/\" target=\"_blank\" rel=\"noopener\">Walnut Shell Blasting Abrasive<\/a>.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-loghome\">\n<h2 class=\"hlh-cl-h2\">Log Home Restoration<\/h2>\n<p>Log home restoration is the highest-volume application of wood blasting. Weathered log exteriors accumulate grey surface wood (photodegraded lignin), old stain or paint, mould, mildew, and insect contamination that conventional pressure washing cannot fully remove. Walnut shell or corn cob coarse grade (8\u201320 mesh) at 60\u201380 psi removes all surface contamination and grey fibres, exposing the fresh, honey-coloured wood beneath and creating a uniform surface that accepts new log oil or stain evenly.<\/p>\n<p>Key technique considerations for log homes: blast with the nozzle moving along the grain direction where possible to minimise cross-grain fibre raising; maintain consistent 8\u201312 inch nozzle-to-surface distance; use a wide-angle nozzle (60\u00b0 or wider) for broad surface coverage on flat log faces; and follow blasting with a thorough rinse with low-pressure clean water to remove spent media and debris before stain application.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-deck\">\n<h2 class=\"hlh-cl-h2\">Deck &amp; Fence Cleaning<\/h2>\n<p>Wood decks accumulate mould, mildew, grey weathered surface fibres, old sealers, and embedded dirt that compromise the adhesion and appearance of new deck finishes. Walnut shell medium grade (20\u201340 mesh) at 40\u201360 psi removes all of these without the excessive fibre raising that pressure washing causes on softwood decks. Blasting also cleans between deck board gaps \u2014 areas that pressure washing directs contaminants further into rather than removing them.<\/p>\n<p>For hardwood decking (ipe, teak, cumaru), which is significantly denser than softwood, slightly coarser media (16\u201330 mesh) or higher pressure (60\u201370 psi) may be needed for effective cleaning. Always test on a concealed area first to calibrate the process for the specific wood species and its condition.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-furniture\">\n<h2 class=\"hlh-cl-h2\">Wood Furniture &amp; Fine Surfaces<\/h2>\n<p>Antique furniture restoration and fine woodwork can benefit from very gentle abrasive cleaning with walnut shell fine grade (40\u201380 mesh) at 30\u201350 psi to remove old finish, grease, and surface grime without sanding through delicate figure or veneer. This is a niche application requiring careful technique: short burst intervals rather than continuous blasting, frequent inspection, and thorough masking of joints, hardware, and adjacent surfaces. For very delicate veneer or intricate carved surfaces, professional assessment of whether blasting is appropriate is advised before proceeding \u2014 chemical cleaning may be safer for extremely fragile or valuable pieces.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-pressure\">\n<h2 class=\"hlh-cl-h2\">Pressure &amp; Technique for Wood Blasting<\/h2>\n<ul class=\"hlh-cl-ul\">\n  <li>Always test on an inconspicuous area before blasting the full surface<\/li>\n  <li>Begin at the lower end of the pressure range and increase only if cleaning is inadequate<\/li>\n  <li>Maintain consistent nozzle movement \u2014 never dwell in one spot<\/li>\n  <li>Blast along the grain direction to minimise fibre raising<\/li>\n  <li>Rinse thoroughly after blasting \u2014 spent organic media left on the wood surface can promote mould growth before the new finish is applied<\/li>\n  <li>Allow the wood to dry completely (typically 48\u201372 hours in good drying conditions) before applying stain, oil, or paint<\/li>\n<\/ul>\n<\/section>\n\n<div class=\"hlh-cl-related\"><h3>Related Resources<\/h3>\n<div class=\"hlh-cl-related-grid\">\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/sandblasting-abrasives-types-grit-sizes-selection-guide\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\ud83d\udcd6<\/span><div><strong>Complete Buyer&#8217;s Guide<\/strong><em>All abrasive types &amp; selection<\/em><\/div><\/a>\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/walnut-shell-blasting-abrasive\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\ud83c\udf30<\/span><div><strong>Walnut Shell Guide<\/strong><em>Primary media for wood blasting<\/em><\/div><\/a>\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/plastic-blast-media-for-sandblasting\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\u2b21<\/span><div><strong>Plastic Blast Media<\/strong><em>For paint removal from wood siding<\/em><\/div><\/a>\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/sandblasting-abrasive-safety-regulations-osha\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\u26a0<\/span><div><strong>Safety Guide<\/strong><em>PPE &amp; dust management for wood blasting<\/em><\/div><\/a>\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/sandblasting-abrasive-storage-and-handling-guide\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\ud83c\udfed<\/span><div><strong>Storage &amp; Handling<\/strong><em>Moisture control for organic media<\/em><\/div><\/a>\n  <a href=\"https:\/\/hlh-js.com\/resource\/blog\/sandblasting-abrasives-grit-size-chart\/\" target=\"_blank\" rel=\"noopener\" class=\"hlh-cl-related-link\"><span>\ud83d\udcca<\/span><div><strong>Grit Size Chart<\/strong><em>Mesh reference for wood applications<\/em><\/div><\/a>\n<\/div><\/div>\n\n<section id=\"hlh-cl-faq\">\n<h2 class=\"hlh-cl-h2\">FAQ<\/h2>\n<div class=\"hlh-cl-faq\">\n  <div class=\"hlh-cl-faq-item\"><button class=\"hlh-cl-faq-q\" onclick=\"hlhClFaq(this)\">Will sandblasting damage my wood?<span class=\"hlh-cl-faq-icon\">+<\/span><\/button><div class=\"hlh-cl-faq-a\"><p>With the correct media (walnut shell or corn cob), appropriate pressure (40\u201370 psi depending on wood species and condition), and proper technique, wood blasting removes surface contamination without damaging the underlying wood. Using mineral abrasives, excessive pressure, or dwelling in one spot will damage wood fibres. The risk of damage is highest on soft, weathered, or structurally weakened wood \u2014 always inspect the wood condition before blasting and test on an inconspicuous area first.<\/p><\/div><\/div>\n  <div class=\"hlh-cl-faq-item\"><button class=\"hlh-cl-faq-q\" onclick=\"hlhClFaq(this)\">Can I use sandblasting to remove all the paint from a log cabin?<span class=\"hlh-cl-faq-icon\">+<\/span><\/button><div class=\"hlh-cl-faq-a\"><p>Yes \u2014 walnut shell blasting is the preferred method for removing old paint, stain, and weathered surface from log cabins and log homes. The process removes paint more completely and uniformly than chemical strippers (which can be absorbed unevenly into the log surface) and does not raise wood grain as aggressively as mechanical sanding. Multiple passes may be required for thick or well-adhered paint systems; inspect after each pass before continuing.<\/p><\/div><\/div>\n<\/div>\n<\/section>\n\n<div class=\"hlh-cl-final-cta\">\n  <h2>Source Wood Blasting Media from Jiangsu Henglihong Technology<\/h2>\n  <p>Walnut shell in coarse through fine grades for log home restoration, deck cleaning, and furniture work.
