I built an outdoor table out of some old heart pine 2x4s and sealed it with a high gloss urethane. The urethane isn't holding up and is beginning to fade. I was planning on going back over it with something that will hold up a little better, but have two questions.
What is the best sealant/protectant to use on an outdoor table that is exposed to the elements?
Do I need to strip the existing urethane off of the table or can I just go over it with the new sealant?
if the old coating is failing, absolutely take it off before doing anything else.
good old penetrating oil stain is the best way to protect all the wood, but you have to refresh it every year or two.
spar varnish is weather and UV resistant, but not proof against them either. you are going to have to sand and reapply every year or two in most climates.
both coatings will darken over time.
sig: if this is a new economy, how come they still want my old-fashioned money?
Thanks for your help. It's not failing as much as it is fading. I'll sand and apply more.
Use Bristal Finish instead.
It has 5 time the UV protection then Min Wax Helmsman spar.
Any place that sells boat suff may have it or check out West Marine on line.
It's not cheap, but drys fast, no snading needed between coats most often.
It's what they use on antique boats to restore them.
