When I’m called to clean a rust stain from concrete the product I found to work the best is Singerman Laboratories Concrete Rust Remover.

MY PROCESS:

It comes as a white powder. You mix it with water into a clear gel. Spread the gel onto the rust stain and let it sit for two to fifteen minutes depending on how severe the rust is.

The rust stain will start dissolving without having to scrub it. Rinse the area to remove the residual rust.

If any rust stain remains, apply a second treatment, lightly scrub it in and let it sit a few minutes. Rinse it off and the rust will be gone.

Watch and see for yourself!

ACE Videos did a really good test to show you how Singerman’s rust cleaner removed rust stains from concrete.

Check it out below for real proof.

Why I use it in my business

My business, Day’s Concrete Floors, Inc specializes in repairing concrete. Removing rust stains from concrete is something I get called to do a lot of.

I’ve tried all the natural methods for removing rust stains. Baking soda, lemon juice, vinegar, coke, and laundry detergent.

None of them come close to working as good as Singerman’s Rust Remover.

I’ve wasted a lot of time, blood, sweat, and tears using these other products with only mediocre results.

Before I found Singerman’s, I tried using just about every other brand of iron out, rust remover product out there.

Sometimes they worked and sometimes they didn’t. It was hit or miss.

Singerman’s rust remover has worked about 99% of the time for me. Nobody’s product is perfect, but this is as close as it gets. (at least in my experience)

When a customer hires me to remove a rust stain from their concrete, I need to be able to tell them with confidence I can do the job.

Now I can. No more “hoping” this will work. No more showing up with 5 different kinds of rust removers.

No more wasting my time!

I’m sharing this information with you because I want to save you a lot of trial and error. I want to save you a lot of time.

But most importantly, I want you to be able to remove your rust stain from your concrete.

See how Singerman’s compares to other rust stain removers

Jeff from Diy Remodeling Tips tests 7 different concrete rust remover products. 

He very clearly shows you which one works best on rust stained concrete.

The ones he compares are:

  1. Zep calcium, lime and rust remover
  2. Goof off RustAid – rust stain remover
  3. IronOUT – Rust stain remover
  4. CLR – Calcium, Lime, Rust remover
  5. Vinegar
  6. Baking Soda
  7. Singerman’s Labs Concrete Rust Remover 

Singerman Labs Rust Remover for Concrete

This page, this information, is coming from a real concrete contractor. A PRO who cleans and repairs concrete for a living.

There’s a lot of other pages on the internet written about removing rust stains from concrete.

I’ve seen them, and read them. None of these other “authors” are in the concrete business.

That doesn’t mean they don’t know how to remove rust stains from concrete.

But if they’re not in the business, what really is their motive for telling you or showing you what they think works?

Is it to get you to click on their recommended product and buy it so they can get a commission?

I don’t know, maybe….. maybe not.

All I know is I do this a lot. This whole website I own is about sharing my knowledge and information with you to HELP you.

Are some of the products I recommend affiliate products also? Yes…  But at least I use them.

And… that’s how I keep all of this information free for you.

Below, I’ll share with you some of these other methods for removing rust stains from concrete I’ve used in the past.

Just in case you want to try them.

Natural remedies and other brands I’ve used. 

I don’t recommend them any more, but they did work on some rust stains.

What causes rust stains on concrete?

Most rust stains come from something metal. The metal could be from a vehicle, patio furniture, or a metal can that gets wet and drips on your concrete.

If lawn fertilizer gets on your concrete, then gets wet, it will leave a rust colored stain.

Sometimes the rust stain comes from within the concrete. If the wire mesh or rebar in the concrete is close to the surface and starts to oxidize, this will form rust inside the concrete and a stain will eventually develop.





How to clean mild rust stains from concrete using a natural household cleaner

If you don’t like harsh chemicals, another way to remove rust from concrete is with lemon juice or vinegar.

NOTE: Singerman’s rust remover is non-hazardous, non-flammable, won’t harm your grass, and has no phosphates. 

Both of these are quite acidic and make excellent cleaners when diluted with some water.

If you have a heavy rust stain on your concrete, you can try using the lemon juice or vinegar without diluting it first. If it’s just a light stain then cut either one 1:1 with water.

Method to clean the rust stain:

  1. Clean the area from dust and dirt
  2. Pour on the Lemon juice or vinegar
  3. Completely saturate the area
  4. Let sit for 5 – 10 minutes
  5. Re-wet if the area starts to dry out
  6. Scrub with a stiff bristle brush (not a wire brush)
  7. Rinse with clean water

If you can still see some rust on the concrete, then repeat the steps above. It may take a few attempts to get the area clean.

If the rust stain is in a difficult area to reach then put it in a spray bottle and spray it on.

The good thing about using lemon juice or vinegar to clean the concrete is if you get some on you it won’t hurt your skin.

Note: If you’re trying to remove a rust stain on painted concrete, make sure you dilute the lemon juice or vinegar and water solution by using 5 parts water to 1 part vinegar/lemon juice.

The citric acid in lemon juice or the acetic acid in vinegar could damage the paint if the solution is too strong.

Baking soda and vinegar:

You can also try mixing some baking soda with vinegar. This mixture will give you a light abrasive (baking soda), that’s good for scrubbing and and acid (vinegar) that helps with cleaning. 

Use the same cleaning method as above!

Will CLR Remove rust from concrete?

CLR also know as Calcium, Lime, & Rust Remover claims it will quickly and easily dissolve and remove calcium and lime deposits as well as surface rust.

The ingredients of CLR area:

  • Water – to dilute the other ingredients
  • Lactic Acid – helps dissolve or remove the rust
  • Louramine Oxice – Aids in removing dirt and oil
  • Gluconic Acid – helps dissolve the rust
  • Tripropylene Glycol n Butyl Ether – A solvent  – helps slow down the evaporation of liquids
  • Yellow #5 – Colorant used to color stuff
  • Acid Blue #1 – Colorant used to color stuff

If you watched the video above you saw how this cleaner was not very effective at removing rust from concrete.

At least not on the concrete in the video.

The ingredients used in this to remove the rust are pretty mild. 

I have used it before with less than satisfactory results. 

I don’t recommend this for removing rust stains from concrete.

Will bleach remove rust from concrete?

This is straight from Clorox’s website. Dr. Laundry recommends never using bleach to remove rust stains from concrete.

Will WD 40 remove rust from concrete?

WD 40 is a penetrant that will help loosen the bond between rust and concrete.

This information is from their safety data sheet:

Product Use: Lubricant, Penetrant, Drives Out
Moisture, Removes and Protects Surfaces
From Corrosion

Contains: Naptha (Petroleum), hydrotreated heavy

Danger!

H222 Extremely flammable aerosol.
H280 Contains gas under pressure: may explode if heated.
H304 May be fatal if swallowed and enters airways.
H412 Harmful to aquatic life with long lasting effects.
AUH066 Repeated exposure may cause skin dryness or cracking.

Although it “may” loosen up some rust and loosen it from the surface, my experience using it as a rust “stain” remover is very good. 

It mostly spreads the stain if anything and it’s really not very healthy to use. 

This is better used for lubricating and protecting metal surfaces in my opinion.

 

Will muriatic acid remove rust stains from concrete?

Muriatic acid will remove rust stains from concrete but it will also remove some of the concrete paste as well.

This acid is very caustic and will burn your skin, eyes, and lungs if you touch it or breath it.

If you do decide to use it be very careful and follow the instructions on the label for safety purposes.

I’ve always cut it 9:1 with water. This dilutes it quite a bit but it’s still pretty strong.

The acid will etch the concrete and could leave you with a different texture in that area.

You also have to neutralize the area after using it. A mixture of baking soda and water, 1 gallon of water to 1 cup baking soda, will neutralize the acid and you can rinse it away.

I really don’t recommend using this to remove rust stains. it’s just too caustic and non-user friendly.

Removing rust stain from wire mesh or rebar within the concrete

When concrete is placed there’s usually some type of reinforcement like wire mesh or rebar used to help minimize cracks.

Sometimes the wire or rebar gets too close to the surface or edge of the concrete during the pour.

After the concrete hardens, you can’t see the wire or rebar, but it’s there just under the surface. It might be as close as 1 inch under the surface.

Over time moisture gets repeatedly absorbed into the concrete which causes the metal to oxidize (rusts).

Especially if your concrete wasn’t sealed properly.

When metal rusts, it expands. The rusting metal (wire/rebar) just under the surface of your concrete begins to bleed through to the surface of the concrete.

Eventually it will expand so much it will pop off a piece of concrete exposing the metal.

The only way to fix this area of rusty looking concrete is to cut out the affected area and patch it back in with a concrete patching material.

Then properly seal the entire section of concrete.

You will not be able to just clean the surface with any of the cleaners above because the wire or rebar in the concrete will continue to rust.

You’ll have to get the area fixed to resolve this problem.

How to make it easier to remove rust stains from concrete

The only way to make it easier to remove rust stains from concrete is to seal the concrete.

If the rust stains are coming from a vehicle or some type of metal furniture, the stains are still going to get onto the concrete.

But by sealing the concrete, the stains won’t soak into the pores of the concrete, they will remain on the surface. This will make them easier to remove.

For exterior concrete I like to use RadonSeal’s Dryway concrete sealer.

This sealer will seal your concrete and keep water from penetrating into it. If the rust can’t soak into the concrete, you’ll be able to remove it much easier.

Nov 24, How To Pour And Finish A Concrete Patio Slab (My Pro Tips)

I’ll show you how to pour and finish a concrete patio slab just like the pro’s do it. From leveling and screeding the concrete to broom finishing.

Republished by Plato

Published

on

The steps it takes to build, pour, and finish a concrete patio slab are:

  1. Prepare the sub-grade
  2. Install the forms and reinforcement
  3. Pour and level the concrete
  4. Finish the concrete
  5. Seal the concrete

prepare the sub-grade for concrete

The sub-base under your concrete patio wants to be either gravel, road base, sand, or crushed rock.

You’ll want to remove any sod, grass, clay, or dirt. How much you remove and replace with gravel will depend on where you live and how many freeze/thaw days you get during the winter months.

If you live where you get some to many freezing days, then more gravel is recommended under your concrete patio. A good base would have 12″ to 24″ of compacted gravel under the concrete.

If you live where you don’t get many temperatures below freezing then 4″ to 12″ of sub-base gravel would suffice.

If you have wet conditions, then more gravel and adding drainage would be recommended in that case.

To help keep frost from getting under the patio, you can install 2″ styrofoam under the slab. This will insulate the sub-base and keep it from freezing.





install the forms and reinforcemenet

The thickness of your patio slab will determine what you use for forming material. Most likely your patio slab will be 4″ thick. That’s quite common for a patio slab. 

IF that’s the case, you can use either 2×4’s or 2×6’s to form your concrete patio. The size and shape of your patio will be determined by you and your space or area you have to install the patio.

Setting up forms is fairly simple. Here is more information about forming that will help you.

For reinforcement, you can use wire mesh or rebar. Both are good and will help reinforce the concrete if it does end up cracking.

how to pour and level the concrete

Pouring the concrete for your patio slab and getting it leveled out is something you might want to hire a professional for. 

If your patio slab isn’t very big, then maybe it’s something you can do on your own. 

Watch us pour this 50′ x 10′ concrete patio and see if it’s something you want to try or not.

To learn how to pour and finish concrete like we do in the video above, check out my training academy The Concrete Underground.

In The Concrete Underground I have many of my best training videos to teach you how to pour and finish concrete just like we do it.

how to broom finish and seal the concrete

Knowing how and when to start the finishing process is one of the hardest things to learn about concrete finishing.

In the video below, I will show you how we start the finishing process and apply a broom finish to the concrete.

The finishing is always determined by how fast of slow the concrete sets up. I’ll show you the best time to start finishing in the video below for best results.

I used a penetrating sealer to seal the concrete with in the video. This type of sealer will not leave a slippery film on the surface but will seal and protect your concrete.

It’s best applied with some type of sprayer. We’re using a power sprayer in the video but you can use a simple garden pump up style sprayer if you like.

tools you’ll need to build a concrete patio slab

I’ve made a list of all the tools you’ll need to build your concrete patio slab.

Most of these you can get at your local hardware store or even easier, you can order them right from Amazon.

Concrete tools list for building a patio slab.

IN CONCLUSION:

I built this page to help you decide if you want to pour your own concrete patio or not. 

If you kind of handy and like building and doing things on your own, then maybe it’s something you can tackle by yourself after watching my videos.

If the size of your patio slab isn’t too large, maybe you can do it yourself with the information I’ve given you on this page.

If you have any doubts or questions, then look to hire a pro like me. We do this kind of work every day.

Nov 21, Fast Setting Concrete Mix (Recipe-Ingredients-Mix Design)

I use this fast setting concrete mix for pouring all types of concrete. When you need your concrete to set up fast, this mix design will get the job done.

Republished by Plato

Published

on

A fast setting concrete mix has the following ingredients included to speed up the set time:

  1. Extra Portland Cement
  2. Water-reducing admixture
  3. Warm water (for mixing)
  4. An accelerator admixture (calcium chloride)

If you need a concrete mix that will set up fast, plan to use at least a 4000 psi mix. This type of mix has more cement than most of the regular concrete mix designs.

More cement in the mix means more heat of hydration as the concrete sets up, speeding up the curing process.

Using warm water will also help speed up the set times, especially if you’re pouring concrete in cold temperatures.

A water reducing admixture will help lower the water – cement ratio in the mix and still give you a workable mix to place your concrete. This helps with set times and improves the strength versus just using water.

Adding an accelerating admixture to the concrete will decrease set times by 10 – 30% in a lot of cases. 

cold weather fast setting mix for floors and patios






In the video above I’m using a 4000 psi concrete mix to pour this concrete floor. The concrete had 115 degree F water, 20oz of water reducer per yard of concrete, and we used two 50lb bags of calcium chloride in each truck load.

The outside temps were 32 degrees when we started pouring the floor. You can see the steam coming off the concrete as we get it spread out.

We started pouring at approximately 7 AM and we finished power troweling at 2 PM. The outside temperature never got above 41 degrees.

The most important ingredients for fast setting concrete are warm/hot water in the mix and using an accelerator like calcium chloride.

These two ingredients will speed up the set times of any concrete mix, whether it’s ready-mix or a bag mix like Quikrete or Sakrete.

does hot water make concrete set faster?

Using hot water to mix concrete will help speed up the set time by speeding up heat of hydration.

Heat of hydration is a chemical reaction that takes place when cement and water get mixed together. 

If the water is COLD, there is less heat that develops and the concrete sets up slower.

If the mix water is HOT, there is more heat that develops, which makes the concrete set up much faster.

Outside, ambient air temperatures as well as mix water temperatures HOT or COLD play a very important role in how FAST of SLOW concrete sets up. Hot = Fast and Cold = Slow (in most cases)

how do you make concrete set faster? (2 easiest methods)

The best and easiest way to make concrete set up faster is to use hot water to mix it with. If you use warm or really hot water, you’ll see an increase in the set time.

The 2nd best way is to use an accelerator like flake calcium chloride. You can use this instead of hot water if hot water isn’t available.

Most local hardware stores carry calcium chloride flakes/pellets in either 25lb or 50lb bags.

If you’re using an 80lb bag mix, only start using about 2 Cups of calcium chloride flakes to see just how fast it starts setting up and adjust up or down from there.

What is the fastest drying cement and concrete mix?

The fastest drying cement mix and concrete mix is the brand called RAPID SET from CTS CEMENT.

They have a rapid setting cement mix called CEMENT ALL. This cement mix sets up in only a few minutes and cures hard enough to walk on in 20 – 30 minutes. It comes in a blue bag or blue box at HD.

CTS also has a rapid setting concrete mix called, you guessed it, RAPID SET CONCRETE MIX. This also sets up in only minutes and has 3/8″ stone aggregate in it. It comes in a green bag and you can get it at HD.

I personally use both the Rapid Set Concrete Mix and Cement All for doing a lot of repairs and small concrete projects. Just beware, they both set up very fast. 

They actually have a “set slowing admixture pack” to slow the set and give you more working time if you think you’ll need it.

what is quikrete’s fastest setting concrete mix?

Quikrete has a RED bag called “Fast Setting Concrete MIx”. They claim is hardens in 20 – 40 minutes and can be walked on in 2 hours.

You can use this 50lb quick drying bag mix for steps, sidewalks, slabs, and for setting fence posts or a mailbox post.

This concrete mix can be used to set posts without mixing. Just dump the dry ingredients around the post and sprinkle with water for it to harden.

This mix will reach 4000 psi in 28 days.

Quikrete also has a “High Early Strength” concrete mix called Quikrete 5000. It’s not a rapid setting mix but does set up faster than their regular bag mixes. (I’ve used it for countertops)

This can be used for most anything; footings, slabs, walkways and floors. Just add some accelerator if you need it to cure faster. It’ll reach 5000 psi in 28 days. 

You can purchase either of these concrete mixes at Home Depot.

What is sakrete’s fastest setting concrete mix?

You guessed it, Sakrete has a 50lb bag called “Fast Setting Concrete MIx”. (I see a trend here)

It’ll harden in 30 minutes and you can walk on it in 6 hours & drive on it in 48 hours.

This can be used for setting posts, slabs, walkways, patios, curbs, and ramps.

It’ll reach 4000 psi in 28 days. You can get this at Lowe’s and most local hardware stores.

fast setting concrete additives – what to use

A fast setting additive for concrete mixes will greatly increase the set time and curing times of your concrete. 

Quikrete has a 1.5 lb Concrete mix accelerator that comes in a green and black box. You can add 1 or 2 of these to a 60 or 80 lb bag mix to speed up the set time. Purchase this right at Home Depot.

Sakrete has a 1 gallon bottle of “Cement Mix Accelerator” you can add to their concrete mix to speed up set time. 

How much you add and how fast they increase set times will also depend on how cold it is outside and how cold or warm the water is you use to mix with.

Another additive that’ll increase set times is flake calcium chloride. Just mix about a cup or two in the mixing water before adding your bag mix concrete. Then mix the concrete and use at as you normally would. Just move a little faster:)

We use a 50 lb bag of calcium per 5 yards of concrete when we pour concrete floors. This increases set times a lot in colder weather. Add hot water to the mix and you have a rapid setting concrete mix.

how much water do you need per bag?

Depending on which fast setting bag mix you choose, you’ll have to add the correct amount of water to achieve the best results.

Each brand is very similar when it comes to adding mix water, here is the breakdown:

  • Sakrete Fast setting concrete mix is 2.5 – 3 quarts of water per bag
  • Quikrete Fast setting concrete mix is 2.5 quarts of water per bag
  • Rapid Set Concrete Mix (green bag) is 3.5 to 4 quarts of water per bag

All these bag mixes have the mixing instructions right on the back of the bag. 

is fast setting concrete weaker than regular concrete?

The answer to that question is no, all these bag mixes are designed to reach 4000 psi at 28 days.

If you add more mixing water than the bags suggest then you could weaken the concrete. But just because it sets up faster doesn’t mean it’ll be a weaker mix.
