Sansin Classic: Specially engineered for log and timber-frame structures.

Specially engineered for log and timber-frame structures.

Classic is the ultimate finish for logs and big timbers – easily maintained, it can keep wood beautiful literally for decades. This low-lustre three-coat penetrating formula not only enhances the natural beauty of wood, it also allows it to breathe. A log home requires more than protection from sun and rain – the sheer size of the wood demands a coating that “breathes” freely to prevent moisture from getting trapped and rotting the log from within.See more.

Not surprisingly, Classic works just as well on other exterior vertical surfaces, like shakes, shingles, siding and fences. Whatever the application, your wood will be protected with an ultra-violet (UV) and water-repellent shield of lasting and remarkable beauty. Classic is easy to apply – with simple soap and water clean-up – and easy to maintain. Simply apply a maintenance coat of Classic Clear UV or Classic Top Coat mixed with the Classic stain of your choice to protect and maintain a perfect finish.Because it uses water to carry modified natural oils deep into the logs, Sansin Classic can be applied even to wood with a high moisture content – particularly useful for log homes where moisture levels of up to 25% are common. By comparison, most water- and solvent-based coatings can only be applied to surfaces with moisture content conditions of 18% or less and once applied, are more likely to trap moisture deep within the logs.Classic can also be used as a penetrating undercoat prior to for Sansin ENS to enhance protection against moisture.CLASSIC OPTIONS
