The house got painted a few years ago with a water based stain put on with a HVLP sprayer. The stuff worked just fine on the walls, which have deep eaves to keep the rain off. But on the flat deck, exposed to rain, the stuff didn't last. It peeled off in big patches and looked dreadful. Stuff was water based but not water proof.
After several years of listening to children bugging me about how shabby the deck looked, a refinish project got underway. Step one was to rent a power washer and sluice most of the old paint away. Was able to get that done fast enough to get the washer back to the rental place soon enough for the half day rate, $44. Between the power washing and the intermittent rain showers, the deck came out clean but VERY damp. Then it rained for a couple of days straight. Deck took nearly a week to dry.
Today I started with a gallon can of Cabot oil based deck stain in Cordovan brown. Used to be "stain" was kinda thin and runny to soak into the wood. This stuff was thick as applesauce, and looked more like paint than stain. No matter, it's paid for now, I'm gonna use it. Took about two and half hours with a paint roller to get it spread. One gallon was just enough to cover the whole deck, not a drop left over.
Then Stupid Beast, who has been patrolling the lawn, takes fright at something and flees up the freshly painted steps onto the just as freshly painted deck. So now we have a cat with four Cordovan brown stained paws. A rag and a bottle of 409 cleaner got most of the stain off the paws. Cat was highly indignant about the entire procedure. At least we avoided Cordovan Brown paw prints on the rugs.
