Hello. This is a great site, with tons of info. so much info, Im a little confused--So here is the history and question:
We bought a house that has a large gazebo (roughly 18' in diameter), handrails/balusters, built in benches, etc. The gazebo is probably about 8 years old. it has either been stained or sealed (I'm thinking stained because of the amount of color) with a transparent seal/stain. There is plenty of color visible, and the grain of the wood is visible--so it is not a solid stain. There is some mold on it, and some worn spots from foot traffic, as well as some greying on the side that gets the most afternoon sun. I would like to get this thing cleaned up and stain it close to what it is currently--basically freshen the whole thing up.
So where do i start?
I'm thinking pressure washing to avoid any scrubbing (lots of railing, then the ceiling, then the ourtside--scrubbing sounds awful!!). PW with a WIDE tip (40degreee??) but how far away or close to the wood. I know depending on the PSI of the PW, so lets say 3000psi. After the PW then what?
From the information I ahve gathered so far, it looks like I am going to have to strip the gazebo first (because of existing stain)?? Can that be accomplished with a PW and deck stripper? which deck stripper?
Then follow again with a PW with cleaner and brightener?
Then apply the stain on the same day? (think i saw something on here that had a stain being applied when wet or damp?) What is the difference in wet and damp?? is wet pools of water on the boards and damp is no pools? is damp 24 hours after the cleaning process?
So many questions. IDK where to start.
Also just found this, so I'll add it:
- Deck Location State: Georgia
- Full Sun, Partial Shade, Full Shade: Full Sun all day (no trees)
- Wood Type: Pressure treated, various sizing
- Mold or Mildew Issues: Some
- The reason for Previous Stain Failure: Not sure how to answer this.
- Previous Coating? If so brand name and type of stain (Transparent, Semi-transparent, Semi-solid, Solid Stain): Unknown
You need to use a deck stain stripper. Apply this and then pressure wash off. Do it in sections. Once fully stripped, rinse all wood well and apply a wood brightener. The Restore A Deck Stain can be applied to damp wood. You can use that if you want or another option would be TWP stains but that will be applied to dry wood, about 48 hours after prep.
I was planning on using the RAD stripper and brightener, then follow with the RAD stain. This looks like a big job, so in terms of "wet" vs "damp", should I plan apply the stripper, pressure wash off, then apply the brightener, rinse off, then apply the stain in sections? For example the top of the gazebo (that little poke out tower on the top), should I concentrate on just that from strip to stain? then move to the ceiling- strip through stain steps? The wet and damp part has me concerned. FWIW, I am planning to put on two coats of stain.
OR should I strip the whole thing, pressure wash the whole thing, then brighten and rinse, and then "section" section the staining part?
Is this a full one day, full two day or full three day task?
Also--Would it be best to spray the stripper and the brightener with a pump sprayer? I am assuming so. BUT with the stain- should I use a roller and brush, or pump sprayer and brush?
Just ordered one of the RAD kits, and a brush. Now questions on pressure washer psi:
I could use a couple of pressure washers-
1- 2600 psi, 2.5 gpm
2- 4200 psi, 4 gpm
Which one should I use? 1 or 2?
I think I saw on this site to use 1500 psi, but then on the RAD site to use 800 psi??
What degree tip should I use? 25? 40?
Am I correct to assume the wider the tip, the less psi I would get on the surface of the gazebo. and then the further the tip is from the gazebo, the less psi I would get? So then which tip at what distance?
How bad is the stripper, brightener, and stain on the metal roof? I am bound to get a little bit of the stripper and brightener on the metal roof.
Would you recommend I brush the strip/bright onto the spindles of the top roof protrusion (see photos above), to avoid getting the strip/bright solution on the roof?
Will it be OK to have the "rinsed" solutions go down the roof if I keep plenty of water on the roof??
The stain should be easy enough to keep off with a brush
