How to Refurbish a Grape Arbor

Examine the arbor. If the arbor is constructed from several different materials, discover what materials need repair and which are in acceptable condition. If you have cement pillars holding the growing ceiling, make repairs to those first. Patch the cement before putting more weight on the pillars in the form of new wood.

Test the wooden portions of the arbor by pressing the screwdriver into them. If the tip sinks in more than 1/8 inch, the wood is rotten and in need of replacing. Use lengths of 2-by-4 lumber and car jack to lift the weight off the portions that need replacing. If the growing ceiling is comprised of joists that are tied together, replace the entire ceiling. Do this in the fall when the vine can be cut back without damaging the plant. Use pressure treated wood and stainless steel or zinc fasteners to stave off future decay.

Leave iron alone, if rust is minimal and without penetration. Grinding surface rust from wrought iron can actually do more harm than good. If rust is more advanced, grind the surface of the iron until there is no more rust visible. Apply outdoor sealant, primer and paint to the iron before it is exposed to moisture.

Seal new wood you have replaced. Use clear outdoor sealant to keep the natural wood look while protecting the arbor from the elements. In order to make the arbor look uniform, you may need to seal the portions of the arbor that you have not replaced, along with the new wood. A quick sanding will help give old wood the same appearance as the new.
