What Is Groutmatch?

Groutmatch is a silicone caulking system designed to match any brand, any color of standard cement based grout, regardless of it being sanded or non-sanded. With Groutmatch you color match your grout with 100% silicone caulking and it can be used interior or exterior.


How does it work?

Groutmatch uses the same dry, unmixed grout straight out of its bag or box that you use to do tile or stone projects. You simply mix it with the Groutmatch caulking material.

Is Groutmatch easy to use?

YES, Groutmatch is so easy to use, anyone can do it. Simply mix unused dry grout of any brand or color with groutmatch and squeeze it into the joints. It's truly the stress free way to match any color grout joint.

Where do I use Groutmatch? / Why do I need Groutmatch?

Many areas in tile and stone installations require a caulking material rather than grout as there will be minor movement, expansion, contraction, etc. If you used grout itself, the grout would crack, break-up and fall apart.
Here are some of the areas that you must use a caulking material for that purpose:

Countertops - Where the countertop meets the backsplash or wall or around the sink.
Bath Tubs - Where the tiled floor meets the tub or the tiled wall meets the tub.
Tiled Walls - Where the tiled corners meet or where the wall meets the floor or ceiling.
Showers - Wherever there is a corner and around the drains and fixtures.
Tiled Floors -  Where they meet exterior doors or where they would meet walls.
Windows - Where you have tile work that is around windows.

Can I use regular caulk?

Yes but the color may not match. Some colored caulks aren't even close and the majority of the ones available are not 100% silicone which means that they will shrink, crack and FAIL.

GROUTMATCH is 100% Silicone which does not shrink or crack giving you years of worry-free beauty and service.

How much dry unused grout do I need?

Generally you want to save about a 1/4 cup per tube of Groutmatch. Inside the tube you'll find a measuring scoop that you will use 1 to 2 level scoops to measure the grout in most cases depending on job site conditions.

How far will one tube go?

Groutmatch is designed to do small and medium jobs as most of the time you just don't need a big 10 ounce tube. Depending upon the size of the joint you are filling and how you apply it, you can expect to get around 15 to 45 linear ft per tube.   
Here is a guide with approximate coverage (depends on installation techniques). 

Joint Size               Linear ft - Groutmatch      
1/8"x1/8"                             58                                                   
1/4"x1/4"                             14                                                    
3/8"x3/8"                              7   
                                                                                                           
Can I use epoxy grout with Groutmatch?

Depending on the manufacturer of the epoxy grout determines if this is possible or not. Some use regular or standard grouts (ones primarily designed to be mixed with water which is fine, while others use a hybrid system that uses a special colored sand (not grout) which will not work. In the case of hybrids you will need the actual cement based grout of the same color for the system to work properly.

Why Silicone is better! 

Latex- vs -Silicone Caulk  

Latex Caulk: Latex caulk is a caulk that includes acrylic polymers, water, latex and fillers. Some acrylic latex caulks claim to contain silicone or at least small amounts of it in an attempt to combine some of the beneficial qualities of silicone caulk with those of acrylic latex caulk. But, these caulks have a high filler content which tends to detract from their overall performance.

Most makers of latex caulks promote themselves as “mildew proof” or “mildew resistant”. During the manufacturing process a mildewcide is added to the caulk, mainly to keep the product from becoming moldy in the tube. But some add a bit more to give a bit of mildew resistance in wet areas. The mildewcides that are used in this process are expensive and add cost to the final product. So it would make sense to make more money, use less mildewcide. This mildewcide also needs to be water soluble in order for it to be mixed with the latex. However, with it being water soluble, that means it can also be dissolved and removed from the caulk by water. Mildewcide is hazardous and is not recommended in areas where it may be exposed to food, food utensils, and food areas like kitchens, sinks or dishwashers.

Silicone caulk:  Silicone caulk is caulk that is produced by the composition of an inorganic silicon / oxygen backbone with organic side groups that attach to the silicon atoms. The number of attachments or links between the inorganic and organic components determines the final consistency of the silicone product. Most silicone caulking products fall into the acetoxy or oxime groups and many are RTV silicones which mean they begin to cure or dry when they are exposed to air.

Silicone caulk has outstanding adhesion and flexure characteristics, coupled with long life and will outperform as well as outlast latex caulks. Silicone is the caulk of choice for showers, tubs, countertops, sinks and other areas exposed to water and even areas underwater. It is also naturally mildew resistant so unlike latex it does not need hazardous mildewcides added to it.

Although silicone caulks are generally more expensive than latex caulks, silicone caulk will remain flexible and has high tolerance to temperature extremes and are able to withstand the suns (UV) rays.

Because 100% silicone is not a food source for mold and mildew spores, no mildewcides are needed in them. This makes them ideal for persons who are chemically sensitive.

 

Latex Pros

Bottom Line - Why must you use a flexible sealant in movement joints instead of grouting them? Because the grout would crack, right?

So why would you use an acrylic siliconized latex sealant that is susceptible to cracking like grout?
 
Movement joints need the protection that a true silicone sealant provides, don't settle for less.

 
While there is no set or determined criteria for the cleanup and removal of silicone caulk here are some tips that may be of use.

How can I remove silicone caulk?
Uncured Silicone Caulk
Remove (scrape, wipe, dig out, etc.) the uncured caulk and then scrub the area down with EMPASI Cleaner, isopropyl alcohol  or denatured alcohol to remove any remaining oily residue. Only use solvents in a well-ventilated area and follow all safety precautions and instructions listed on the product label or as otherwise provided by the manufacturer. When solvents are used, proper safety precautions must be observed.

Cured Silicone Caulk
Because silicone is made to last, it can therefore be a bit difficult to remove.  If the need arises and you must remove it, follow the suggestions below.

 

First, remove as much as possible by cutting/peeling/scraping excess caulk from the surface. Try cutting down along both sides of the joint. This should facilitate the ability to peel the sealant out in strips.

 

Note: before using any solvents it is recommended to follow the manufacturer’s directions in the proper handling of it and you should always test an inconspicuous or hidden area of the surface first to ensure that discoloration will not occur.

  • For Formica®, fiberglass, etc., use EMPASI cleaner and a non-abrasive (white) scouring pad. Test on a hidden area of the surface to ensure that discoloration will not occur. If discoloration does occur, contact the manufacturer of the surface for further assistance.
  • For ceramic tile, marble use EMPASI cleaner, denatured or isopropyl alcohol and a non-abrasive scouring pad. Test on a hidden area of the surface to ensure that discoloration will not occur. If discoloration does occur, contact the manufacturer of the surface for further assistance.
  • For glass surfaces, use a razor blade to remove as much as possible, then apply EMPASI Cleaner. Remove excess with a towel or other suitable cleaning utensil that will not mark the surface (such as a non-abrasive pad).
  • For surfaces that are hard plastics or painted, use EMPASI cleaner, rubbing alcohol and a soft cloth. Do not use mineral spirits.
  • To remove caulk from a porous/rough surface (concrete, brick, wallpaper), remove as much of the caulk as possible (same as smooth surface). If necessary, use a wire brush in conjunction with EMPASI  cleaner.

NOTE: Do not use a wire brush to remove caulk from wood surfaces, as doing so could damage the wood. Also, solvents can damage the finish on wood products. Test solvent on a hidden area before applying.

Most solvents are flammable and should be used away from sparks, flames, and other sources of ignition. Only use these solvents in a well-ventilated area and follow all safety precautions and instructions listed on the product label. When solvents are used, proper safety precautions must be observed.

Special notes about silicone caulk:   If you are reapplying silicone to the area, remove the old caulk, and then clean the area with a disinfectant especially when mold or mildew is present and then clean with EMPASI cleaner or denatured alcohol.  Let the area dry thoroughly before reapplying silicone. Do not use soap to clean surfaces to be sealed because the silicone can not adhere to surfaces covered with any soap scum present.

Do not use mineral spirits on uncured silicone caulks.
