    Hey All,

    Has anyone here powerwashed, then sanded and stained their deck? I just got through the powerwashing part of this.

    I was wondering, what should I use to sand now that the deck is actually power washed. I was going to go with a 5" Random Orbit Sander. My deck is 20x10. So I wonder if I am just going to be killing myself using that.

    So just wondering what you guys have done. At this point my next step is using a nail punch to knock in all of the nails.

    Yeah, you can use a power sander, and yeah, you're going to be killing yourself. That's unfortunately the nature of the beast. You really need to make sure you're getting off all the varnish/sealant/whatever (and yes, this means getting into the cracks if possible), so use multiple grains, or at least one go-over with coarse paper and then another with fine paper, say, a wetsand paper, before you re-finish.

    Well the powerwasher really got everything off. I am just trying to get the grain nice and level now, cause the power washer did kick off some of the "summer wood".

    Wow, that's one tough powerwasher. You're probably on the right track then.

    Haha, yeah, I think a little too rough.

    But that wood was really old and in bad shape. OK, good, I wish I didn't have to sand, but hopefully if I do this, then I could just use Oxidized Bleach the next time around.

    What do you guys think is best to use as a sealant. I haven't decided yet if I want the wood look or if I just want to paint it. I just know I don't want to do this again with this deck.

    I just did this myself I will see if I can find the pictures I took. My deck was beyond saving with a power washer I had to replace all the planks, railings & spindles.

    How rough is the wood? If it's already started to rot, you may have to steam/pressure treat/bleach or something to it, or its just going to keep rotting under the finish, no?

    Well, that is why I power washed it. The wood under all of the saw dust that washer got up is good. So a sanding should be fine now.

    I'd rent a stand up sander from home depot if you don't want to kill your back, however you need a damn sturdy deck to handle those (the ones people use to refinish hardwood). I find Johnson's waterseal to be the nicest protection and allows the woods natural finish to come through.

    I was thinking a oil sealant with some honey color tint to it. Don't the oil stains last longer? Or so they say. I will be pissed if it turns grey by this time next year.

    Here is what I started with it was beyond saving if I tried to power wash it all it would have done is splintered. The spindles were shot and the steps were falling apart the nails had rusted completely thru.

    It took one whole Saturday but by 8pm the new wood was down and I slept the whole next day.

    Two months later in fact just two weekends ago we painted it because the frame & foundation was the old wood and the new wood on top just looked out of place so we painted the whole thing to match.

    I second this. Once you hit it w/ the sander all you'd have to do is get the spaces between by hand. Pretty simple. If the wood is cracking you can get some exterior grade wood filler, like they use on indoor wood flooring, but you'll have to resand again.

    Your before actually looks better then my deck did before. I think that was saveable though. From what I read, you power wash that, let it splinter, sand it down, then seal it. That is what I am doing. Having said that, mine is going to take 3 or 4 days to complete, yours took 1 day. So your way is better. I am already commited though.

    Your after is great. I just don't have the tools for the after. Plus, if I was to do that, I would just tear down the whole deck and go with Trex and call it a day.

    Well, what is a crack exactly? I mean, my whole deck has cracks in it.

    I was thinking a stand up sander too initially. How much those things run usually?

    Any good power washer with the deck cleaner crap added should do fine.(do not get to close with it, they will cut thru wood lol)

    Been there done that 25*25ft deck in back along with a 8*10ft in the front.

    Douche's used no stain, paint, water sealer or nothing on it, hey its only like 3-4k$ worth of wood right?

    I had to repair a few areas, but it was saveable. Does it look like new, hell no, but has some decent life left in it with a few simple repairs here or there.

    Forget painting wood unless u just want to repaint it again. Same goes with any water repellant crap I or my family has used.(this goes double if its a deck around a pool)

    Grrrr damn name slipped my mind now, brother mentioned it and after talking to several folks who do decks and housing its all they recommend now. Damn. I will have to either remember the name of the stain or ask the gf what it was. Just pick about 3 shades lighter than the shade u pick off the chart. doh I will post the name t'row.....

    I used to work at Home depot for basically my whole university experience and we ALWAYS recommended Thompson's water seal, so I think that may be what 3.8 is mentioning. It comes tinted or natural and in a ton of different colors. it's oil based so it will last a long time and goes on easy. just make sure your kids/pets aren't around it (it stinks!)

    I just orbital sanded mine. It's about 8x8 is all, so it's tiny. It only took a couple hours. I still need to stain it though. Orbital should be fine.

    Yeah, I think the sander will do wonders for it. It's not going to be perfect. But I don't have the money for perfect at the moment. It will more then do for a while anyway.

    Thompsons is like buying car part at Autozone, the warranty is great if u like replacing it every year.

    Alucard(and others) the stain is Sikkens. Its expensive, but has been used in family the past few years and recommended by contractors I've talked to.. Up to this point has outlasted any other stain/water sealer/whatever else we have used.

    I ended up coughing up for it for my front and rear decks here as well.

    Also did the new stairs for the apt as well with Sikkens.

    Like I mentioned earlier, pick the shade u want then back up 3 on the chart and get that, should get u rightish where u want it.

    Rent a floor sander and go for a ride on the deck, just don't mention what u are doing with it when u rent it :)

    All I did with mine is hit it up with a power wash and then stain it with the flood stain. If you have any water damage you will have dig it out and fill it or use wood hardener on it then stain it. Decks are a pain in the ass to maintain.
