Tiger Sheds strongly recommends that your garden shed be treated shortly after assembly and then annually thereafter with an appropriate high-quality preservative. Tiger garden sheds come pretreated with a water-based preservative in Burnt Orange for storage and transport purposes. A log cabin comes untreated. However, we do recommend that you retreat your garden building with a high-quality solvent-based wood preserver, and we offer various types and colours of treatment to treat the shed yourself. Our very own high quality TigerSkin preserver offers maximum protection of your garden shed or fence, manufactured by preserver specialists AChem. Our solvent-based wood treatment will penetrate deep into the wood giving years of protection against the weather. It will enhance timber grain with a rich long-lasting protection. A water repellent formula which is harmless to plants when dry.
