What Is Solignum? Solignum is a wood preservative designed to protect timber from wood-rot, fungal attack, wood-boring insects, and termites. There are different variants: Brown Solignum penetrates deeply into wood and leaves a brown tint; it preserves against termites, fungi, and decay, and allows painting or varnishing afterward. Colourless Solignum provides the same protection without changing the appearance of the wood—ideal for projects where you want a natural look. Solignum Soilguard is a soil termiticide containing cypermethrin, applied to the soil beneath or around buildings to form a termite barrier. It’s diluted (1:200 with water) and covers a wide area economically. — How Effective Is Solignum Against Termites? In scientific studies, Solignum-treated wood showed significantly reduced weight loss from termite damage, indicating strong protective effectiveness. Real-world reports also support its use: A user noted that thoroughly soaking wood with Solignum—rather than just lightly brushing—successfully eliminated the termite problem: > “Make sure you mix the solignum in the proper concentration… The wood being treated should be soaking wet with the solignum mixture… soak that well in solignum.” Another user shared that their father used Solignum and now they have no termites: > “solignum gigamit sa akong papa, op. wala nay anay sa amua ron.” Summary Use Cases for Solignum Product Variant Application Type Best For Brown Solignum Brushing / Immersion Exterior or visible wood where a brown finish is desired Colourless Solignum Brush / Spray / Immersion Interior or outdoor use without altering appearance Soilguard Soil treatment around foundations Building-level termite barrier prevention Tips & Safety Notes Application method matters—ensure deep soaking for effectiveness rather than a light surface application. Ventilate the area during and after application to reduce inhalation risk. Clean-up can be tricky—controller handles or areas treated may retain stains or odors. For residue removal, users recommend: Wiping with warm water and mild soap Using a wood-safe cleaner or mineral spirits for tougher stains Absorbing odors with vinegar, baking soda, or activated charcoal Final Recommendation For invisible, clean finishes, go with colourless Solignum. For a natural, rich finish, brown Solignum offers the same protection with enhanced aesthetics. For ground treatment, choose Soilguard to create a long-lasting termite barrier around your structure.
