Experience the exceptional durability and long-lasting protection of Intergrain Heavy Duty (formerly known as Intergrain DWD), a high-build, water-based exterior timber finish. Designed to withstand harsh weather conditions, this product offers a tough, UV, water, and mould-resistant finish, making it ideal for all exterior timber, including decking, windows, and doors. With a 4-hour recoat time, it ensures efficient application and superior performance.
For maintenance, if your existing Intergrain Heavy Duty coating is in good condition, simply clean the surface with Intergrain UltraPrep™ Timber Cleaner. For new timber, treat it with Intergrain UltraPrep Tannin & Oil Remover before cleaning with UltraPrep Timber Cleaner. Grey and weathered timber with no previous coating should be cleaned with UltraPrep Timber Cleaner, and severely weathered timber should be sanded back to a fresh surface before cleaning. For existing coatings in poor condition, remove the coating using a combination of UltraPrep Tannin & Oil Remover and power washing, followed by cleaning with UltraPrep Timber Cleaner. If mould is present, use Intergrain UltraPrep Mould Killer as the first step in preparation.
