Hi guys

What would you use (if you would do that) to sand a deck after you pressure washed the deck?
The wood is cedar

thanks

What kind of square footage are we talking?

If it’s something like a 10×20 deck grab yourself a 4”x24” sander and some kneepads. The sander will come in handy later for stuff like tabletops and benches.

Makita and Triton both make good models.

If your deck is half the square footage of your house, as seems to be the trend anymore, you might want to rent something like this

If you use the belt sander have a dust collector hooked to it and wet the areas you’re sanding with a spray bottle as you go, just enough to keep the dust damp. Sparks from sanding the screw heads can light the dust on fire pretty easily.

I’ve had to figure out how to extinguish a fire in my Makita in a hurry… More than once…

The size is 10×10
Renting a floor sander is out of question as I have to sand some rails and boards that top the fence at chest level
no nails, I used a homedepot sold under deck rail that you use to attach the floor

I a afraid to use the band sanders as I can’t control the depth and it might make small gaps in the wood
I also have a sheet sander but that is small…
I am thinking about a circular (or orbital?) sander

A length of 2×4 with 60 grit automotive self-stick strips. Will knock down the high spots pretty quick and you can then stain it.

With all our power tools, we forget how easy it is to do some things by hand.

in some spots I was pretty rough with the power washing and I need to make that look better…in some other areas the wood lost the brown stuff between the white lines in the picture, so I want to level those

80 grit and one of these

seems to be working, better and less destructive than the pressure washer

I honestly think all you want to do is scuff the area. Like many things in life less is more. My advice is get a drywall sander thingy much like a floor mopper. Than give it a good overall even sanding nothing to excessive your just trying to get the wood to absorbed the deck finish. Just make sure your deck finish has a really good UV protection rating.

You’ll do just fine.

I personally would just use a random orbit sander.

I already had one but it did not work
You need to be able to apply some pressure on it and the mop like thing is not working

I tried to use a sheet sander as well but it did not work well
The above is the best as it allows you long strokes along the fiber

It is going to rain and I am not done with the sanding
Will it hurt if the deck gets when where I sanded it already ?
Should I drop a tarp on it or let it soak a little?
I want to know if the now sanded areas-sanded after pressure washing) will lose some or all the capacity to absorb the stain

It’s fine…. I belt sand the joints on my deck as my one year old grand daughter got splinters crawling on it. Belt sanded and smoothed out the edges. Not a problem anymore. The screws were countersunk…

Pressure wash every year without a problem…

The belt sander is too heavy and I can’t control it properly and do the areas that I want

You can use a ROS. If the screws are locking the deck boards down, after you sand you should have no problems after that..
