Topic tags/keywords: question

The dock at the beach house is in need of a proper rehab, some have suggested ironwood decking, others just slap on some we stain. My thoughts are somewhere in between; sanding it down and applying a penetrating finish that I won’t have to touch for at least 10 years. The conditions are heavy UV, salt water splashing and not a whole lot else. It’s currently decked with 2×6 TYP about 20 years old and most are structurally sound but starting to reveal many splinters that little feet don’t have appreciate. Any thoughts would be greatly appreciated.

Having grown up in the Florida Keys, all we used was normal pressure treated stuff and water sealant for the decking. They got a fresh coat of water sealant every now and then as needed. Never did use any kind of staining, as we wanted the wood to bleach towards white to reduce heat – and they typically lasted a good 30+ years or more before needing to be re-planked.

Pressure wash and stain or some other form of weather proofing

In my opinion and that of many others, there is no such thing as a penetrating finish that will even last 2 years. In fact, I don’t know of any so called penetrating oil finishes that are any better than nothing at all. I have tried several products on my deck work. Opaque stains work better than anything else I have tried. I have rebuilt several decks. Nowadays, pressure treated lumber doesn’t last near as long as it used to because arsenic – copper compounds have been banned.

Thanks for the suggestions, as of now it looks like some version of what the good, old formula Thompson’s water seal applied after pressure washing makes the most sense.

Pressure wash on low pressure, sand a bit if necessary, and then stain or paint with the most opaque thing I could find would be my choice, but then I don’t like re-applying things constantly.
