How do I stain raw unpolished concrete floors? I know there is a product that I saw in Knoxville, TN, that is water based and can be sprayed on to the concrete floor, but I don't remember the name. I now live in Puerto Rico.
I am looking for a portland cement based paint. Many years ago this was a product made for contractors, but went "soapy" while on the shelf, making for a very short shelf life. There are some preformulated dry paints that require just adding water, even some with colors. Where are these purchased in N texas?
Hi Bethinbfe. So sorry about the patio.:smileysad:
Yes, you can apply a concrete stain over the top of the dyed patio..Keep in mind that the dyed concrete will influence the color of the stain. For example; if the dyed concrete is red and you apply a light beige stain over the top - it may turn out pink or flesh tone.You may want to consider doing a solid stain if you are thinking about a big change.
You will need to let the existing concrete cure for about 2 weeks before applying any stain.
I have a similar question: We had our cement patio poured this week and it was dyed, but the wrong color! I REAAALLLY hate the new color. Can I stain it now? Do I need to wait? Should I use the etcher first? Thanks for the help. Bethinbfe
I'm not familiar with products like you describe, "acidic stain."
If you would clarify or better yet, post a photo of the product.
ACID WASH FLOORS:
For years, DIYers have created "acid wash" floor coating using several basic steps:
1) Clean and coat the floor with stain (water-based or oil-based will do);
2) Wear protective eye gear, acid gloves, and protective boots;
3) Thin muriatic acid with water (1 to 1) in a plastic bucket;
4) Pour the solution onto the floor, creating acid flow into the low spots or uneven surfaces in the concrete;
5) Allow the acid to etch the new stain, creating random flow marks and allow to air-dry overnight;
6) Rinse with fresh water several times, evacuating with a wet-dry shop vac; and
7) After dry, consider adding a protective clear coat.
Because these techniques expose you to acid that will burn your skin, many DIYers have chosen to create a very similar appearance simply using multiple colors of semi-transparent stain.
ACID WASH APPEARANCE W/OUT MURATIC ACID:
More recently, DIYers make acid wash floors like this:
1) Wear protective eye gear, acid gloves, and protective boots;
2) Clean the floors with a mild etcher like Behr Cleaner Etcher, rinse and evacuate with fresh water and a shop vac;
3) Choose three, progressively darker colors of Behr Semi-transparent stain;
4) Use a pump-up garden sprayer and a 3/8th nap roller on a pole for application;
5) Set your spray tip to throw a stream of stain, instead of a fan;
6) Starting at one edge, back up while you rotate your wrist in a loop that spatters the stain in irregular puddles onto the floor;
7) Use your roller to spread the puddles, but DO NOT roll all the puddles into an even coating;
8) Your goal is to maintain the irregular shape of the stain puddles, leaving the surface uncoated and heavily coated in different areas;
9) Allow to dry at least six-hours;
10) Clean your sprayer with fresh water, and then apply your second color onto the still-exposed concrete;
11) With a fresh roller cover, roll the second color slightly overlapping into the now-dry first color;
12) Use your third, accent color to spatter small areas that still have no stain;
13) This accent color will visually be only a very small amount of the floor ... creating noticeable, but intermittent spots of color; and
14) Once dry, consider using a protective clear coat over the floor.
You can create your acid wash floor either way.
The old school, true acid wash tends to create more distinct swirls as the acid picks up and move the stain into random "flows."
The new school non-acid floor will have more of a faux appearance as the colors overlap. The contrast in this floor comes from selecting three colors that contrast ... light base, medium second, and third accent colors.
Whenever pet residue is embedded into the floor, you must remove that residue before applying a water-based coating.
Water-based stains will reactivate the stain as well as the odor, and both will bleed back through.
So, take time to clean thoroughly as described earlier, before applying a water-based floor coating.
Will I get the same results by using an acid etcher and the semi-transparent stain that I would if I used a milder etcher/cleaner and an acidic stain?
Concrete is porous and pet urine or feces embedded into the surface will certainly take several cleanings (three or four) to ensure removal.
And, you are correct!
Both the remnants from your pet and the remnants from the chemicals used to clean the floor will cause your water-based paints or stains to discolor.
This is why I note above that you will need three or four cleanings.
YOUR PRODUCT QUESTION: "Is dye a better choice over (these) stains in case there is any residual in the concrete?"
No, Behr's dye kit, semi-transparent concrete stain, and solid color concrete stain are all water-based products. If any residual remains in the concrete, all three will discolor as the pet stains bleed back through ... typically within six to eight months.
The only solution to ensure you seal those stains is an oil-based flooring primer and/or an oil-based floor paint.
In most situations, I would prefer stain over paint because stain is a penetrating sealer that leaves the traction of the concrete intact. Paint, on the other hand, is a surface coat that can be slippery when wet and also requires much more effort to recoat when it begins to flake.
PERSONAL EXPERIENCE: Several years ago, a tenant kept a large dog in a 10 by 12 chain link kennel built into one bay of the garage. Upon moving, the floor had to be pressure washed and deodorized four times to remove the pet remnants as well as the odor.
I used an orange detergent cleaner and a scrub brush to clean. The orange cleaner deodorized and the reputation of orange cleaners proved true ... leaving no visible sign of the problem.
After scrubbing, I allowed the fluid to sit on the surface (but not dry) for about ten-minutes to help deodorize, and used a medium-pressure, wide-fan pressure washer tip to rinse. The wide-fan tip (25 degree) spread the force of the water over a larger area and prevented pitting the concrete.
I repeated this cleaning cycle four times to eliminate both the stain and odor.
MY RECOMMENDATION: Based upon this experience, I believe you can remove all of the pet remnants and odor. You are not likely, however, to remove them with just one cleaning. So, allow time to clean and deodorize completely ... then use concrete stain to obtain the easiest to maintain quality floor coating.
The first thing that caught my attention in your description was the phrase, "stained carpet from previous owner's dogs."
If you simply mean the surface of the carpet had dirt stains, then by all means proceed.
However, if you mean the dogs "marked" the floor regularly (you would likely notice the odor), then you're on a completely different project list.
For purposes of this answer, I'll reply as if it is just surface stains. You can follow-up if you need detail about removing pet odors.
So, here are your project steps after removing your pool table and other furniture:
1) Remove and discard the carpet, carpet pad, and tack strips;
2) Fill the nail pits using Quikrete Repair Mortar in a caulk tube;
3) If your floor is not smooth enough for your satisfaction, Tool Rental can provide a Diamond Blade Etcher;
4a) If you use the Diamond Blade Etcher, simply vacuum the remaining dust and you're ready to stain;
4b) If you're happy with the floor after removing carpet, use Behr Cleaner Etcher to open the pores in the cement;
5) A wet-dry vacuum will help remove the rinse water that follows etching ... Be Careful this solution is acidic;
6) Allow the surface to air-dry and apply your stain; and
NOTE: In this process, I have described concrete stain. This is a penetrating sealer for concrete that comes in solid color or semi-transparent. If you want an overall even color on your floor use solid color. However, with semi-transparent you can create a multicolored faux finish on your floor. Either product will provide a protective coating and either can also be sealed with the concrete sealers described in #7 above.
FINALLY: If you notice pet odor or the floor is discolored by pet urine, you'll need to use an oil-based floor primer to seal the odor before applying floor paint. If you apply a water-based stain, paint, or primer over these pet stains, you'll reactivate the stain and it will bleed through your coating. Follow up after removing your carpet and we can discuss this process in detail.
