We have a large cedar deck that's two years old. The clear stain only lasted
a year and a half before greying. This spring, I want to have the deck power-
washed, and then I'll stain it with a Sikkens stain with some pigment. My
wife has a Polish friend who owns a power washer. He says he'll clean it for
free. The contractor who built the deck said you have to be careful when power-
washing. If you use too much pressure, you'll lift the grain of the wood and
damage it. That's why I'm planning to ask a professional to do it. Is there
a danger to asking an amateur to do it instead?

Thanks!

Too much pressure and you can carve your initials in it. Sikkens
website has very specific instructions for preparation, which include
cleaning and sanding, he
