Protect Timber from Moisture, UV Damage & Everyday Weathering

Outdoor timber is constantly exposed to the elements. From harsh Australian sun & seasonal rain to moisture, dirt & temperature changes, unprotected timber can gradually fade, dry out & lose its natural appearance. Whether you're sealing a brand-new deck, refreshing weathered fencing or protecting outdoor furniture, choosing the right timber sealer helps preserve the timber while reducing ongoing maintenance.

Diggers timber sealers & protectors are trusted by builders, landscapers, property owners, maintenance contractors & woodworking professionals who need reliable protection for exterior timber. Formulated to help repel moisture, minimise weathering & maintain the natural beauty of timber, these products are suitable for a wide range of residential, commercial & trade applications.

Before applying a fresh protective coating, older finishes can often be removed more effectively using Diggers Paint Strippers.
