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