I live in one of the 16 states, where, for environmental reasons, I cannot buy the 100 series. So I'm planning on using the 1500 series stain. Below is a cut-and-paste of TWP's recommended surface preparation for the 1500 product. The following three things surprised me: the long wait time before applying the stain, washing the wood with 1:1 household bleach to water mixture, and power-washing the new wood.

Will the wood grey during the long exposed wait time? Will the bleach destroy the lignin in the wood? Will the power-washer remove the outer layer of wood fibers?

Anyone have experience with this product and process?

TIA

SURFACE PREPARATION:NEW WOOD:

New wood should be allowed 4 to 12 months

of natural weathering before finish coat

application. After aging, wood should be

cleaned with a solution of 1 part household

bleach to 1 part water. The bleached surface

should be thoroughly rinsed with water, power

washed and then allowed to dry a minimum of

48 hours in good drying conditions before

finish coat application.
