Grout dried to light or the wrong color

This section will show you the best way to get your new tile grout back to it's original intended color. 

Cement based grouts discolor for many reasons, and their are few remedies for this situation when this happens. To wonder and contemplate who's fault it is or how it happened, won't get you to a solution. For now the problem needs to be resolved and the best way to restore the grout back to it's intended color is by the application of GDC grout stain colorants.

Before the introduction of grout colorants - The only way to fix a grout discoloration problem was to either cut out all the grout, or acid wash it. Both procedures, had many flaws.

1# Grout removal- Sometimes the grout was removed, but when you regrout their is still a chance that the grout would discolor a second time. And while their are contractors who will cut out the grout and regrout, the floor or wall it is also expensive to have done and usually damages the tile. Note: you can't smear new grout over old grout it will eventually crack and dislodge from the tile joint. New grout must be re-applied at least an 1/8- 1/14 inch deep into the grout joint, a very expensive, time consuming and laborious job. 

 2# Acid washing- Another old way of trying to bring back the grouts natural color is by using muriatic acids, this was under the pre tense that the grout might have, dried grout residual on top of it, or that the grout had efflorescence problems. And they used Muriatic acids as a flawed remedy to these problems. In very rare cases sometimes an acid wash would work, but most often it would fail.  Also Muriatic acids are extremely damaging to tile and grout. Not to mention the health hazards associated to using strong acids. 

3# Grout colorants-  Grout colorants were first developed by the tile industry, as a restoration technique used to solve many grout discoloration problems, and today it is still the industry standard. So with the advance in colorant technology, we now rely on grout colorants to not only recolor cement based grouts but to seal them also.

So in conclusion don't worry if your grout dried the wrong color, our GDC grout stain colorants are the solution to your problems. 

4# What color to pick?- If you liked the color that you originally picked when you were, in the tile store you just need to know the grout manufacturers name and the color name, you can then cross reference that information to our GDC on line manufacturers color charts, Or you can browse the different grout manufacturers colors that we match to our GDC grout stain colorant formula. Using the link below Please use double clicking. You are now on your way to Recoloring, Restoring, and Sealing your tile grout.

If your tile grout has been previously sealed

Our GDC grout stain colorants form a very strong bond to, cement based grouts. However to increase that bond it is important to make sure the the grout is free of and dirt, sealers or other contaminants, to achieve this, we recommend that you use our GDC sealer remover, before colorant application. And for older grouts you can use the GDC pre treat cleaner, after the sealer remover has been used. The pre treat cleaner will make the grout more porous and will allow the grout to absorb the colorant deeper. If you are not sure whether or not the grout has been sealed  try this test below.

Try this test 

bullet

Place some water on the grout, if it darkens, that's because the grout is porous and their is no sealer present, and will readily absorb moisture, which is ideal for colorant application.

bullet

If the grout remains the same color and the water beads up then the grout is sealed and needs to be stripped, with our GDC sealer remover.

bullet

After your grout is sealer free, cleaned and then color sealed, you could pour coffee all over it an it would wipe up clean.

Below are the easy to understand steps. To prepare  your existing grout for colorant. Please note that you might not need to do all of the below steps to prepare your grout for colorant.  Please print this out for easy reference.

bulletIf your grout had been sealed before,  or if your grout was colored with a grout colorant before, you must do  Step One first.  If you are not sure if it was sealed or colored then do this simple test, pour some water on your grout, if the grout stays the same color or the water beads-ups (like when you wax your car), that usually means that it was sealed or colored. and you must do Step One below.  If the grout changes color (gets darker) or the water absorbs into the grout then you can skip to Step Two.. 

 
bulletStep One- you will have to use a Tile and Grout sealer remover, to remove the old sealer  before you can color the grout , use your own sealer remover or purchase our GDC sealer remover.

 
bulletStep Two-repair any missing or cracked grout, you can put in any color grout that you want, it will not matter because the colorant will make all of the grout one even color. If you have sanded grout (very rough) then you should do your repairs with a sanded grout. If you have unsanded grout (smooth) than you should do your repairs with a unsanded grout.  Let the repair "cure" for 7 days before applying the colorant
bulletStep Three- If your grout is newly installed (less than a month old) and is in good condition and very clean and was not washed with heavy chemicals than you can skip this step and go on to Step Four.  Clean all of the grout with this solution-- 1/2 cup white vinegar to 2 gallons of hot water, scrub the grout with a small stiff brush, (make a new solution if the solution gets dirty or as necessary) then rinse the entire floor with water, let the grout dry for at least 48 hours before applying the colorant.
bulletStep Four-Pour Grout Colorant into a small dish and apply onto grout joint using a toothbrush or If using a GDC application bottle, pour colorant into the bottle and apply directly to grout joint. While lightly applying pressure on the bottle gently allow colorant to evenly flow out. Spread evenly, working Grout Colorant into joint using a back-and-forth motion Do a small workable area at one time. Clean colorant off of the tile with a dry rag no water, wipe excess off tile as you go, skimming lightly over the grout joint. After grout colorant is applied and excess is cleaned up from tile,  Do not put heavy amounts of water on your floor for the first week. Wipe up any spills with a damp sponge.  The first real cleaning of your floor should be with warm water only no chemicals, For floors first sweep area. Then mop while rinsing the mop and changing the water constantly.  After the first cleaning you can use a Neutral pH cleaner to clean and maintain your floor.  Never use vinegar, bleach, acids, alkalis, or ammonia when maintaining floors. And always vacuum or sweep before mopping your floor.  Save any extra colorant in a tightly sealed container for "touch-ups". If going from a dark to light grout color, more than 1 application may be necessary.

Give your tile and grout a new look.

1# Our GDC grout stain colorants will give your tile and grout a whole new look and Seal the grout also. That's right, by simply Color Sealing your tile grout either the same color or by changing the color, you will make your floor look new again. You can choose from a wide range of colors, it doesn't matter what grout manufacturers color was originally installed in your walls, floors, or countertops, or whether you have sanded or unsanded grout.  

Now that we have explained how our GDC grout stain colorants can revive your tile and grout. It's time to explain how these products are applied. Our GDC grout stain colorants form a tenacious bond to floor and wall cement based grouts. But in order to achieve this bond, the grout needs to be basically clean, and must be free of soiled contaminants, and water or oil based sealers. This rule of thumb applies to every and any grout coloring product on the market not just ours. 

 

So here's how you Restore, Recolor and Seal older tile grout.

1. If the grout is sealed remove the sealer with our GDC grout sealer remover

2. If the grout has not been sealed then, you should clean the floor with our GDC pre treat cleaner, this is a slightly acidic formulae with no surfactants, that deep cleans the grout and opens the pours of the grout so the colorant can penetrate deeper.  Some of our GDC grout colorant kits contain the pre treat cleaner.

3. Next, select a grout color you can choose from any grout color chart

Need to ask an Expert

Our GDC grout stain is very easy to apply, but since every floor and wall grout restoration project is unique, their are going to be questions that you will have, while we encourage you to read, research and browse our website and check out the trouble shooting guide. We understand that their are going to be times where you might need an expert for advice, in such case please contact our Expert department at groutdye@aol.com

You can also browse frequently asked questions below

Q-Can I get expert advice on the phone- No, we are usually to busy to answer the phones and also we need to have the right tech rep answer your questions, everyone specializes in specific areas   Please email us your questions to groutdye@aol.com

 Q-Should I seal my grout? Yes, it is one of the most important things that you can have done. You can use a clear penetrating sealer, but we feel that it is better to seal your grout with our GDC grout stain colorants. They offer better topical protection then most penetrating sealers and maintain grout color.

Q-I have a tile floor that is five years old, the grout was never sealed, can seal with a grout colorant product ? Yes, but it must be cleaned first.  Since it is old their might be some stains that won't come out.  You seal the grout for two reasons, the first being for easy maintenance and the second reason is because grout is porous.  Every time you wash your floor or take a shower, a little bit of moisture seeps into your sub-floors or walls. Sealing the grout can help prevent this.

Q- We recently had our Shower Tiled and Grouted however the contractor but down the wrong color. Can we use your colorant on are shower walls and floors? Yes, you can use our grout colorant on your shower walls and floors, however please note,  it will possibly have to be touched up in a year or sooner depend on the traffic and water in your shower.

Q-Should I clean  (maintain) my tile floor with vinegar? No, No, No-it is only used as a shock treatment or a mild acidic wash before using a grout colorant

Q-How can  I tell if grout is cement or epoxy?  What is the best way to clean each?  I have a slate floor with grey grout and when it was clean some of the colorant was removed but not all of it.  In addition, the drying time was excessive in spots but not in others.  Could this possibly be due to  improper installation? The floor is only 1 year old but is heavily used, and is only mopped with plain water 2 times a day. How can  I tell if grout is cement or epoxy? Take a small amount of  phosphoric acid drop it on a grout line if it bubbles then it is a cement grout if it doesn't then it is epoxy.

Q-Does the Grout Dye Company also do this type of work- Yes, Our phone number is here because we are also a restoration company that serves the tri-state area.  We sell the colorant/dye that we use ourselves in our restoration services.  That's why we know it works!  We are Grout, Stone, and Ceramic Tile Installation and Restoration Contractors.  We are located on Long Island, New York and currently serve the entire east coast with our contracting services.  The Grout Dye Company (G.D.C.) offers various types of restoration services unlike those of "regular" tile contractors.  Please visit our Restoration Page.  There you will find an in depth list of the services we can provided for you.  We are willing to travel almost any where in the world, email us your problem and location, and we will give you a price for the contracting work.

Q-I have an entrance way into my home that is made up of terra cotta red, odd shaped stone or tiles.   I'm not sure which.  My question is since I'm not sure of the material, can i still use your product to dye the existing grout to a new color? Also, if it is stone, why can I not dye the grout? Grout colorants are not recommended for natural stone materials. They can be difficult to remove if applied. Some customers have great success applying masking tape to the outsides of the grout joints while applying colorant.

Q-What if I need a grout colorant color that you don't offer?  Can I have a custom color made?  Yes, you can order a custom color? Read below to see how its done:
1. Select a paint chip from a reputable paint manufacturer with the color you want reproduced to a Grout colorant/dye/ stain. Then you can email us the color name and the number of the chip.  
Note-please pick a color that is a matt finish.
3. We will email you back to tell you know if we can make the color.
4. After that, the payment is as follows- Which can be paid for on any of grout colorant pages (custom color button, located towards the bottom of the page) Please don't pay until after we tell you that we can make your color. Custom colors are also non-returnable, (they will come out about 97.9% close to the color chip).  Please make sure that this is the color that you want.  They also take a little extra time to make as compared to standard in stock color.

Q-Will your grout stain colorants look like grout that's been painted? No, our GDC grout stain formulae will leave your grout looking natural and will also leave behind the grouts original texture. They also dry to a matt finish.

Q-It seems really hard to apply the colorant to my floor?  Its not hard to do, its actually very easy to apply with a tooth brush, its just takes time. And the bigger the floor the more grout joints there are, the longer it takes and the more your knees hurt, (we suggest doing a little at a time and wear knee pads!)  Only do what your able to handle and clean up one at a  time, you can always continue tomorrow.

Q-We recently re-tiled our bathroom. We resealed the shower area. We are getting a white calcium/crystal like substance on the grout and tiles. We thought it was soap scum and have tried almost all bathroom cleaners to remove it and nothing works. Do you have any suggestions? A-1.Efflorescence, -which are salts from the grout that deposit on the tiles surface due to a lot of moisture under the tile installation. 2.Calcium bicarbonate- Due to hard water. Remove with CLR
3.Grout left on the tile That's all I can think of, a mild acid wash will solve these problem but be Careful and wear safety equipment..

Q- We recently had our Shower Tiled and Grouted however the contractor but down the wrong color. Can we use your colorant on are shower walls and floors? Yes, you can use our grout colorant on your shower walls and floors, however please note,  it will possibly have to be touched up in a year or sooner depend on the traffic and water in your shower.

Hi Mike,
I just wanted to pass along how well your product worked for me on the Home and Garden show that I did a few weeks back. I don't know yet when my show will air, I will get the info. about a month prior to the air date and I will let you know then.  We put a couple of coats on top of the brown to get the grout really white and it looks amazing! I have attached two photos for you, the first is the before picture and the second is obviously the after. Thank you again for such a great product, it really saved me on the show! By the way I did mention your company name several times during filming, but I have no control over editing. Hopefully they slip your name in there somewhere, I'm sure they will!

Hi,

Here are the before and after photos of my project on the Home and Garden show. Thanks for all your support! Actually this is not a contest, it's just a new series that HGTV has started. It's an interesting concept since I have never seen a home makeover show that invites student designers to redo a room in someone's home. They came to my school, Academy of Art University in San Francisco and we interviewed to do the show. I was selected as well as about 20 other students and we are the first season of this new show! I graduate this December, so essentially my true test as a designer will be coming soon. I was very pleased with the results of your product and will recommend it to anyone who is looking to give their tile a different look. Thanks again!
