Stripping Behr Solid Color 100% Acrylic Latex

I am sorry but deck stain strippers do not remove solid color stains. You would need to wash then re coat with another solid color stain.

Please advise what you mean by "wash".....power wash, water, or what?

Wash with a pressure washer to remove anything that is loose or dirty.

We have been stripping a deck of Behr premium acrylic for some time now. We started by pressure washing the deck and prepping the surface with deck stripper. As it is getting to be the heat of summer, I’d suggest applying to a 5x5 area and scrubbing with stiff deck brush. Keep the area wet and scrub it in as you wet. Wait until in starts to appear to dissolve or break up on the surface (looks like gravy skin) and then hit with pressure washer. You may to apply more than once to an area with the acrylic. If you are going to cover again with acrylic, you may not need to sand (accept rough patches on the deck) If you want a light color or switching to an oil base, SAND, SAND, and SAND EVERY SURFACE! (We are switching to TWP 1500 series) use 60 grit for good results I would use anything less than 80. Get a deck sander (home depot $60 for a day plus pads and sanding papers). Make sure you run heavy sanders through a 20 amp outlet (kitchen) and use a 10 gauge cord. Anything under 10 will cause deck sander or drum sander to trip. Any uneven areas, hit by hand with belt sand or orbital. It is an incredible amount of work to sand every square inch of a deck but worth it to it right and switch to an oil based stain.

Thanks for your tips and experience!

We just stripped our deck with Thompson's waterseal stripper (because I hadn't found your forum earlier to learn about the other brands!). The previous owners had some kind of dark red opaque stain on it that looked horrible. No idea if it was water or oil based.

It came off with the stripper and a lot of brushing and a pressure washer. The hardest part was the stairs, as it appeared they had been repainted over with something else too...
Then we sanded by hand with sandpaper wherever there were spots that didn't come off. We did a pretty good job, I'd say 90% of the red paint is gone! However, it looks like some parts, like the railing, were assembled AFTER they were painted red, as there are spots that are inaccessible with the sandpaper.

The only thing is we replaced the deck floorboards with new treated pine ones. We thought it is too much work to strip instead of simply bying new boards.

This being said, we are planning now on washing and brightening the wood and then painting with a semi-transparent stain from Armstrong-Clark.
Do you advise that we do more sanding?
Will the Armstrong-Clark look equally well on the old and the new wood? Will it cover up well enough those spots that we can't remove (under railings, around wall corners, etc.)?
Do we apply 1 or 2 coats of stain in this case?

One more question:

Would the EFC-38 Wood cleaner do a better job at washing off any remnants of stain, as I read it can strip somewhat, rather than the RAD cleaner for instance?

Cleaners do not remove stains. You would need a stain stripper. In addition stain strippers will not remove solid stains or paints effectively. Semi-transparent stains will not cover up solid stains/paints. Semi-soilds would do a slightly better job but still will not cover a solid stain/paint. The old solid stain/paint will show through.

So to confirm, I can't use a deck stain stripper on the Behr acrylic latex stain. All I can do is pressure wash, clean and then reapply the same Behr acrylic latex stain?

Other options are to sand it off or replace the boards.
