Apply by brush, roller, or dip-immersing enough of Smith's Original and Genuine Shou Sugi Ban Surface Stabilizer to fully saturate the char layer. Due to its advanced control of surface tension, wet-out of the char layer is extremely rapid, typically complete in a few tens of seconds to a minute, perhaps more on very deeply charred wood.

A suggested application method that gives highly consistent results is to immerse each Shou Sugi Ban plank face-down in an immersion-trough containing perhaps a half-inch-depth of Smith's Original and Genuine Shou Sugi Ban Surface Stabilizer. The plank typically floats about half-immersed, thus all edges as well as the face receive a uniform application. At the end of about 30 seconds, lift up the plank, rotate ninety degrees so the face drains-off across the width of the plank, and observe the wetted char runoff. Usually, no area goes-instantly-dry and the runoff ceases in a few tens of seconds, although this will vary with the individual wood. Allow to drain until runoff ceases. If immediate further absorption is seen with drainage, return to the application process to obtain further absorption.

This is a one-component product; unused material may be returned to its original container for later use.

For application by brush or roller, continue to apply until there is no further absorption.

Allow the water-phase to evaporate by natural convection or forced-air ventilation (nominally 50-100 lineal feet per minute), at ambient temperature. Do not attempt to accelerate the process by heating. Full water evaporation typically happens within a few days (at nominal 72F), as is the case for plain wood. Full chemical cure of the resin system takes place within this time-frame.

Accurate determination of the drying time would be obtained by weighing a treated wood sample and drying to constant weight; that would indicate the completion of the treatment-process.

The drying time is strongly dependent on ventilation, ambient temperature and relative humidity.

CAUTIONS

Do not apply to wood that has recently been exposed to rain or condensation, such that the moisture content of the underlying wood is above 20% as measured by a non-contact moisture meter. Do not apply where there may be exposure to rain or condensation during the application or drying process. Do not apply below 40F, nor above 95F. Do not apply in direct sunlight. Do not apply where the ambient relative humidity (R.H.) may be above 80%.

Do not allow exposure to temperatures below 40F, or product-damage as coagulation may occur, rendering the material unusable.
