Acid Stained Man Cave

Hi all:

* The pictures really don't do justice to the "river effect" that we created. I think with better lighting and a better picture taking, you'd see the pattern (or lack of pattern) a bit better. I just wanted to show the process.

As I stated in my "DIY Floroquartz Floor" thread, the next phase was to acid stain the "man cave" and basement of our new house.

The "man-cave" which unfortunately may be my daughter's 1 year cave (expecting - a blessing of course), is 460 sq. feet with shower, in-floor, and sink what was supposed to be my all-in-one deer hunting and processing room - lol.

We are going for a two color, drastic, marble effect using malayan buff and coffee brown from directcolors.com. I was lucky enough to talk with a pro that submitted photos to that site and he emailed me some of the technique. We figured if we screwed up on the "man cave" it really wouldn't be a big deal.

The floor was power troweled so we did use their special acid etching solution called "floor prep." I am not sure how it will turn out, but here are the pics so far.

Started off in the bathroom. May have "pooled" a little too much of the coffee brown:

A pic of the process. Spraying the lighter color stain first and then making pools of your darker color so it runs. We did 460 sq. feet in about 2 hours:

We finished at 6:30 p.m. last night and now instead of washing it off after a few hours, the technique we are using is to let all of the acid completely dry. Then, sweep it off and then wet a 1' x 1' area to see if we like the colors. The pro said wetting an area will give you a fairly good look at what it will look like with a sealer. If you don't like it, you can apply some more stain.

We diluted our malay tan 1:4 and the coffee brown 1:1.

Hopefully we'll like the color when we run over there today and I'll get a coat of sealer on.

Sure. If you are laying down 2 separate color stains, you saturate floor with the lighter color first. We were doing about 3 - 4" width sections at a time. Then, you randomly put in heavy puddles of the darker stain. I did some 8" circular puddles, some 2' line puddles, and would do some 2-3' arcs.

Then, over these darker stain puddles, you apply your lighter stain over the top of them. At first, you won't see it run, but after about 1 min you will see the darker colors starting to "flow" away. It was really enjoyable.

Then, he told me to let the stain completely dry before rinsing it off. I think in more traditional applications you let the stain sit for the required amount of hours and then rinse it off.

The "pro" I talked with told me to be pretty random with the puddles so that you don't create a pattern. I guess that is where the "artistic" side of each individual kicks in.

We went out this a.m. and the "dried" look was quite a transformation. Alot of it washed away when we rinsed the floor, but we were surprised.

The dried look photos will be up soon.

Dried Acid Stain

Here is the look that we saw this a.m. prior to rinsing off acid residue:

This is a "wet look" photo I think.

Another "wet look" photo I believe.

**The "pro" said when you rinse it, the wet look that you see will give you an indication of your final color.

Alot of the whiter and light tan colors turned more to gray when we rinsed the floor. Never doing this, I am unsure if that will be the "sealed" look or not. We were sort of shooting for how the floor looks "dry" right now.

I think the 1:4 dilution of the malayan buff was too much, or the floor prep didn't etch enough for the weaker dilution to take effect.

Never-the-less, the coffee brown shades with the lighter gray concrete that we see in the wet look still looks really nice. I hope to put 2 coats of sealer on later today and will post pics if possible.

I spent all day mopping up the residue over and over until the rinse water was clear. I would have to say I underestimated how much work that would be.

Much of the dramatic look is now mellowed with more grays and brown. Still nice looking and interesting, but if I want a more tan color I'd have to reapply the malayan buff color again and repeat the washing tomorrow.

For the house, we have a 1:1 and a 1: 2 ratio test patch of malayan buff that we'll look at tomorrow.

Will do Scotty. I have the sealer and will be putting wax over the top as it will be a pseudo apartment for my daughter.

One snag though, the mop i used left a bunch of fuzz behind, gonna have to spend some time cleaning that up tomorrow.

Have seen some really nice acid stain floors, and some really iffy ones. For the novice it's a bit of a gamble, even pros go into it not knowing exactly what the finished floor will look like.

The last one I did was a 900 ft2 patio with several different sections, some old, some recent, some parts slick, others porous. We ended up using a lot more acid stain than we anticipated, and even then the results were underwhelming.

But do seal it, unless you want the floor to lose its intensity.

I will post some pics tomorrow I hope. After scrubbing off the acid residue, a lot of the tan (malayan buff) became more gray. After the 2nd sealing today (even after the first one) the gray in the "wet" photo above is now a darker green. The floor almost comes off as a camo look when wet. We will see what it looks like when it dries tomorrow. I should be able to put 2 of the 4 coats of wax on tomorrow as well I hope.

In our basement, we are planning on going with a 1(acid):2 (h20) with the malayan buff instead of the 1:4 we used on this floor.

As Alpha said, this floor was a bit inconsistent in porousity. It was also power trowled and I think I could have used a stronger mix of their floor prep to etch it a bit more.

Will try to get them up soon. The drywaller is working in there right now so it is pretty messy.

However, we did a different dilution - still malayan buff and coffee brown - in our basement and here is a post acid drying and a finished 5 coats of wax over 2 coats of sealer.

The picture really doesn't do the floor justice in regards to looks and gloss. It looks like glass in the right light.

It took SIX moppings to get all of the acid residue off before sealing. I wish we could keep the colors of the first picture, but most of it is dried acid sitting on the surface.

We are really happy with the basement floor colors - cost $0.50 per sq. ft.

Dried acid - we left the acid dry on top over night per advice from a pro:

Finished product - again the picture doesn't do it justice - it really looks like polished rock/marble:

The floor has many different shade variations from grays to dark browns which really give it a "natural" look of marble - hopefully when all lights are installed in the basement I'll get some better pics.

Here's a pic of our log house, thought I'd throw that in for good measure. This weekend I get to tackle staining and finishing the ash floor on the main level. The Amish did log portion of the house and a contracter did the rest.

Yes I was up on that scaffolding today with my full hunting vest staining and sealing the 16' center beam. Glad that is over for awhile - lol.
