You don't necessarily "NEED" to seal it, but it is a wise choice! Grout is a cementitious material just like concrete and both absorb water unless they are waterproofed. Absorptive concretes develop structural issues and require repairs with chlorides and other contaminates which enter and cause reinforcing steel to corrode.
Grouts merely absorb stains and discoloration becomes an eyesore. Mop water that isn't changed often enough when cleaning will be absorbed and turn grout joints dark, and spills are wicked into a grout within seconds.
I have beige tile and grout in a kitchen/family room area that is six years old and looks brand new. Sealed with a product called StableCrete to waterproof the day after it was installed. Common response to visitors walking in, "What a beautiful tile job, is it new?"
What else can I help you with?
Is it good to seal tile and grout?
Yes.... But if the tile is glazed and/or the grout is epoxy (unlikely unless in a commercial building) these do NOT need to be sealed (neither will absorb water so they won't accept the sealer). The rule of thumb is to put a few drops of water on the tile and the grout, if it soaks in within 30 seconds it needs to be sealed. Never use a topical sealer. Always use a waterbased PENETRATING sealer. You will need to reapply bi-yearly or yearly in most situations, more if the tile is exposed to water. Hope this helps..........
Should you put a sealer on concrete flooring?
Yes, so that the concrete doesn't break or split.
Why is your grout green when you put it in?
If your grout appears green when mixed, it may be due to the presence of green-tinted additives or pigments specifically designed to create that color. Additionally, some grout formulations can react with moisture or other chemicals, resulting in a green hue. It's also possible that the grout has picked up color from any surrounding materials or surfaces during mixing. Always check the manufacturer's specifications to ensure the desired color is intended.

Can you put epoxy over sealer on a overlayed concrete floor?
Yes there are certain kinds of epoxies that can be applied over SOME sealed floors. It depends on what type of sealer was used first. They tend to not bond well with some solvent sealers, but water based ones will work. You just have to use the right epoxy primer so it will bond

How do you grout tiles?
It is somewhat painstaking. There is a grout removal tool available at most big box hardware stores. It is basically a handsaw that uses hardened aggregate applied to the blade instead of teeth. You have to shave each joint down to a level below the surface that a new grout can be applied to and adhere (about 1/8" for non-sanded grout and 1/4" for sanded grout). If you are changing grout colors, you will want to use an acid (muriatic acid) to wash down the joint edges to remove any small amounts of the old grout at the surface edge that remain, prior to new grout installation. Because you are not installing the new grout to the full tile depth, it is advisable to use a latex additive to prevent cracking.
Can you put water base sealer over oil base sealer?

Can you put new grout over old grout for a tile renovation project?
No, it is not recommended to put new grout over old grout for a tile renovation project. It is best to remove the old grout completely before applying new grout to ensure a proper and long-lasting bond.
When should you put the sealer on the grout?
Apply sealer as soon as the grout has lost the "Heat of Hydration"; usually in a matter of hours. Choose a sealer carefully! Read the cautionary statements on the product you are considering! If it cautions "Do Not Allow Product To Come In Contact With Glass or Metal Surfaces" Don't even consider it! More than likely a Sodium Silicate based product that migrates out of the grout very soon, and it will etch glass and any metals it comes in contact with! If it allows for a Re-Coat at some future date? Ask yourself- OK, what happened to the first application I put on? You put sealer on EARLY to waterproof the grout and stop the rapid evaporation of mix water from the material. This evaporation causes shrinkage cracks in the grout. Even Microscopic cracks in a grout will increase in size with traffic and result in a delamination of the grout. I use a product called that is manufactured exclusively for, and sold by my company. Waterproofing grouts immediately will retard evaporation of mix water and give a superior bond to the tile itself [on the side of the joint] and to the substrate [host concrete] below. You will know when you have achieved proper saturation levels of the product when it is no longer being absorbed into the grout. Come back the next day and pour water on the area you have waterproofed; it will pond and remain on the surface until it evaporates. In kitchens or on a rough sanded grout I make another application the next day. If the second coat is not able to penetrate the grout I know its waterproofed and mop up the excess product. This prevents the product from drying on a surface to form a film. The product works by forming a solid inside when it reacts with the alkali and does not leave a film. When friends come to my house and comment on my kitchens "New Tile" I pour grape juice or ketchup onto a joint, proceed to tell them it's 6 years old, it's waterproofed grout, with a 15 year warranty for waterproofing and after 10 or so minutes-- I wipe the Stain up!! If you waterproof the host concrete beneath your tile install, you will also avoid a delamination of the thin set mortar that holds the tile in place. That hollow sound of a tile when you walk on it, is a dead give away that the tile is no longer bonded to your floor. Do it right the first time and ASAP.
