Cleaning weathered wood…
« on: August 26, 2021, 06:26:14 PM »
…like barn wood. 
I have a job I need to bid installing some barn wood as an accent wall in a home. 
The wood belongs to the homeowner who has already had it denailed, Kiln dried and currently piled in her garage.  

My thought is to straight line rip it, “clean it,” and install it with my finish nailer. 
I’ve seen a couple of handheld brush sanders -the Makita which is near $600 all the way down to a porter cable which seems like junk. 
There is also a brush designed on an angle grinder platform that seems heavy enough to be worthwhile having. 
What do you guys do to knock the dirt, chicken crap, and stuff off the barn wood but still leave the saw marks, etc??
This will be in a stairway wall. So there’s good chance it rubbed and bumped on a lot. Need to get the loose stuff off. 

I do what the little voices in my wife's head tell me to do.

I have seen some nice looking material that was clean with a 3M brush that was called Brushlon.  So, I do think a brush is the way to go.  Check out

Light pressure wash, stiff scrub brush, rinse and dry. Just scrub off the dirt and leave the wood.

I have the junk Port a Cable you speak of and have used it many times.  for a small job like that, I think it will work well and it has a vac port so you can pull some of the chicken poop into your festool hepa vac.  Also, after that I do agree the boards should be washed with a light power wash and if you have enough $$ in the job, hit with a clear coat using water based latex stain or water based poly while on horses.  I also recommend 15# felt on the wall first so one doesn't see white in between the boards as one ascends and descends floor to floor. 

 Sorry, more than you asked, I just cant help myself....

we took some barn wood and split it on the mill to make it thinner and double the sq. footage for a wall.

Thanks for the reply’s. 
This is the first time I will be dealing with this wood. So y’all experience is valuable to me. 
Cabindoc, I have not used the PC only have seen reviews on the internet. So it’s good to hear you think it will work for this job.  And thanks for the other tips. I think a clear seal coat would be a nice touch. 

I’m going over today to get a look at the situation and talk about the details with the owner. 

Another use of the brush tool could be barrel stave projects. I have been building a few things with staves lately and they can be dirty. So I have another need for a good cleaning tool and process.

Crusarious

This will have to be part of my cost projection. 
I have the SawStop table saw and I will need to run the saw in “bypass” mode. Not just because of a missed nail. But the rust left behind by pulled nails could trigger the brake. 
I will need to remember to bypass every time I turn on the saw! It’s easy to forget. One forgetful cut can cost me up to up to $175 in a ruined blade and new cartridge. 
Aside from that, the dirt will just kill my blades. We are without a local saw sharpening service right now. The guy I used retired and I haven’t been able to find someone else, yet My blades are piling up!

It sounds like I’m being negative about the job. But I’m not. Just trying to think through all the issues and expenses that are “hidden” costs.

After de-nailing I always used a wooden handled SS wire brush on any wood that went through my planer. I've torn down several old barns & houses so we are talking lots of wood. I'd then blow it off with high pressure air. Over many boards you WILL miss some nails and tacks or remnants of them. Never tried that 3m Brushlon but I've used the coated abrasive brushes trying to save time on hand (whack a gouge style ) carved bowls. Most of that type stuff is pricey though. A simple round wire wheel works well but an eyeball accident waiting to happen as they fly all over the place. 
Depends some on the species and what look that ladies after?

I think @tule peak timber made a machine to do this although I think it was to add interest to some of his artistic foe creations.

Be very careful with a power washer as on old barn wood, the surface fivers, and several hundredths of an inch deeper,  are weaker than normal, so they will fuzz easily.  The resulting surface will be very fuzzy with lots of loose fibers.  The appearance may not be acceptable to a customer.  If you take all these fibers off, the "barn wood appearance. Will be lost.

If you are just cutting thin boards on a regular table saw you can switch the blade out with a 7¼ circular saw blade, cheap to replace after hitting nails. I would recommend a good face shield though.

Not sure if this is possible with a SawStop saw.

A stiff scrub brush on a broom handle and a garden hose would be safer for the wood finish than a pressure washer.

Did my weathered WRC Adirondack chairs with my pressure washer set on the lowest setting with no issues.
My goal was to remove the gray patina and stain.
Had no issues but sounds like you want the weathered appearance.

The Sawstop must use a 10” blade. There is a .070” gap between the blade and the brake cartridge that must be maintained for the system to work. 
I could just by the cheapest 10” blade available. 

I’ve ordered this and will see what it does this week. 



 

But will use this brush wheel

The polisher and wheel came in and I gave them a test drive on these three materials… an old, dry wine barrel stave, a piece of spalted log, and a very weathered piece of barn wood. 
The plastic wire wheel is labeled as 120 grit. 


 
And here are the results. I know it will be tough to see the real difference in these pics. Aside from the look, the feel of the polished material is very nice.


The left side is untouched  the right side is polished…

 

 

 


 

Before…



 

After…



 

This 120 grit wheel removed the lose stuff well and polished the splinters just fine. It did not remove any wood or texture, which is what I am after. 

And this was just a quick 10 second pass on each piece. I angled the sander in the corners and crevices,too, to see what would happen. I don’t notice any change in shape of the material. Just smoothness to the texture. 

This tool is pretty well balanced and feels good to work with. It’s definitely an outside tool. Maybe even with a fan blowing across the work. It isnt terribly loud or high pitched. 

But this was just 2 minutes of playing with it. We’ll see what I think after handling it a while.

I had some old barn sheeting, and a buddy wanted it to line his daughter's store.  He took a sander and sanded the boards just enough to make them somewhat smooth, but leave the saw marks.  The sander cleaned up the boards as well, and instead of getting splinters if you get up against the wall, it feels smooth.
Most everything I enjoy doing turns out to be work

Well, I landed this installation job. The wood is in very good condition and was already 90% denailed. 

I gave it a once over with a wire brush and air compressor and pulled the remaining nails. 



 



 



 



 



 

After sorting it and counting, there’s about 300sqft. There is plenty more 8/4 boards in case I need to add some later. But this should be close. 

These boards are fairly straight so getting dimensional pieces from them should be easy enough.

I have a sandrite b12 brush sander.    I originally used 60 grit paper but now use 40 grit.

Grizzly makes a similar machine.  Although it probably isnt worth buying one for a single job.

I finally got around to installing this barn wood. Mostly, anyway. Need to go back today to finish the job.

This was all sent through the edger at Teenswingers place. This stuff was amazingly flat all things considered.

The customer wanted as much “character” included  so I didn’t plane anything. With all the boards at 5 1/2”, little height differences help make the wall a bit more 3-D.

Also, no T&G. So I used trim head screws to attach to the wall. The screws are able to pull the boards flat against the sheet rock.

Each step has to be coped.


 



 

The tread lights and switches need box extenders. I trimmed the doorway out with 8/4.



 



 

And I walked 3.5 miles between the mitersaw, table and up/down the steps yesterday.

Oh, and only 36 steps between the bed and coffee pot this morning. 😂
