Sikkens Cetol HLS Plus is a high-quality, solvent-based, low-build wood stain perfect for exterior use on various wood types including softwoods, hardwoods, plywood, block board, and particle board. It is suitable for applications such as claddings, fascias, architraves, timber frames, fences, and sheds. It can be used on its own or as a base coat for other Sikkens finishes like Cetol Filter 7 Plus. This formulation offers a flexible coating that prevents peeling and cracking, helps prevent surface mould and algae, and provides a translucent, semi-gloss finish resistant to UV light. It is important not to use this product on surfaces previously treated with water-repellent wood preservatives containing wax, oil, or silicone, as it is designed for smooth wooden surfaces only. For standalone use, three coats are recommended. If used with Sikkens Filter 7 Plus, apply one coat of Cetol HLS Plus followed by two coats of Filter 7 Plus.
