Coming back for a second pass.
The photos are of the rail of a 1903 Queen Anne. Some of the 2X12 is original, some does not appear to be. All is pretty weathered.
On the Palouse, so really wet spring and drought for a couple of months.
Andy Engel (whom we all miss) recommended replacement with CVG cedar. I want to avoid that if I can. After looking at a client’s situation, I wondered ‘what about a fiberglass repair?’
First step – strip the old paint
Second step – clear the old fill out of the checking and replace it with high-viscosity epoxy.
Third step – wrap all exposed surfaces with fiberglass mesh and epoxy it.
Fourth step – Successive layers of epoxy, each narrower, working back from teh outside edge to create a slope.
Fifth step – Wrap all exposed surfaces and apply epoxy to create a smooth surface sloped to the outside.
It sounds like an incredible amount of work. But something must be done.
Thoughts? Is the unavoidable moisture cycle going to tear up the epoxy and fiberglass?
