Backbrush Armstrong-Clark?

[cande]

Going to use some AC soon. Those of you who use AC, do you backbrush? If so, how? Truck brushes work well on the horizontals I'm told. What about the spindles, lattice, etc.?

Eric,

We have only done three A-C jobs, two on cedar, one on ipe'. IMO, any heavily pigmented and/or linseed oil type stain should be backbrushed. Spray it on, brush it out. Goes fast with two workers.

Don't bother trying to brush out lattice, spray and go.

[bigchaz]

We spray the spindles and then walk around and brush out any runs or heavy areas. Unless we messed up and sprayed way to heavy in a certain area, I don't bother backbrushing the lattice

[PressurePros]

Everything should be back brushed to even out tone, eliminate drips and work the product in. A/C can be a little opaque on the surface of spindles if overapplied and not brushed in. I agree trying to back brush lattice is an effort in futility. Let it sit and anythiung that is not absorped or that is puddled up can be pushed in or picked up with a dry brush. Using a wet brush on lattice just makes the problem worse.

Thanks guys. Ok, now another question. Is it forgiving? How concerned do I need to be about keeping a wet edge?

Ive notice in the reds that it will lap in a way. Pretty easy to work with but you still need to be careful about going back on areas soaked in. It's not bad just noticeable. Didnt seem to have the same problem with the Super Cedar or the Cedar Semi

I don't know all this lapping business - lapping is something painters have to be concerned with when painting clapboard siding with paint. Back in the old days - and perhaps a technique I may revisit - we would get a 9" roller with a lambs wool cover and roll one board at a time - I'd get in the habit of rolling 3 to 4 boards at a time. There are issues with getting between boards - but there was never any lapping problems.

I'm not sure what you are saying Dan. You like rolling instead of backbrushing?

Dan, you have a tendancy to sometimes overcomplicate..

This is what I am talking about. In this case I did the bottom level and then the top level. The overspray from the top, although looked much better when dried, was still noticeable. I also noticed it in the Sequoia/Natural mix. It's always better to back brush by the way, and keep a wet edge.

In this business the cardinal rule is: Start a board, finish that board.

Absolutely. It also is a good idea to tarp under rails also when you are spraying. You never know when you are going to get back to the floor.

I've experienced some flash drying with the A/C. I'm fairly certain the few times I have witnessed it was under circumstances that all products would have done the same (direct sun, hot, dry wood). Are you folks out there having any issues?

In addition to the above, what type of spread rates are you getting?

Ken,

For AC Rustic Brown on 5 yr. old knotty cedar, ~ 175 sq. ft. per gal.

Relearned that rule last year. AC will lap.

Had not used a linseed oil based stain for years. Left my best helper on our first AC job to stain, while I did estimates. This was entirely my fault.

He cut in by the house by hand, prior to using an HVLP to spray and backbrush the floor. This is what we always do using a paraffinic oil stain and I did not think to instruct him otherwise. See the first pic.

Easily and mostly fixed. A second application evened the lapping out, although you can still notice a slight color line.

Mine has been 140sf-170sf on older wood and in the 200sf-215sf on newer wood

Why would you bother cutting each board 3 feet out from the house and do all of them at once? I cut each board one at a time as I get near the side of a home - when I can't get any closer with my sprayer.
