Sealing your tile grout is essential and it is an easy DIY project, however with the abundance of different products on the market, you may be wondering what grout sealer to buy. The ideal grout sealer depends on your budget, the location of the grout as well as your specific needs. This article will cover the topic in full and help you to decide what grout sealer is best for you as well as provide an overview of the grout sealing process. Read on to find out more.<\/strong><\/p>\n

 <\/p>\n

What is Grout Sealer and Why is it Necessary?<\/h2>\n

Let us start with grout. Tile grout is a powder containing cement and limestone. Sometimes it may contain a pigment or sand. It is mixed with water to create a paste that is used to fill the spaces between newly installed tiles. Once it has dried, grout prevents dust and dirt from collecting in between the tiles and it also prevents excess moisture from getting underneath the tiling. However, grout can be porous which will absorb water which can lead to mold or mildew growth, and in the worst-case scenario, it can lead to structural failure.<\/p>\n

\"Grout<\/p>\n

Choosing to apply a quality grout sealer can prevent the grout from soaking up moisture and thus increase the longevity of your tiling as well as keep it clean and free from stains and mold growth. Mold growth on tile grout can become hazardous to human health if it is neglected and allowed to flourish. It is advised to remove the mold before it becomes a problem. An important part of sealing old grout is cleaning. This article will also cover some of the methods for cleaning your grout effectively.<\/p>\n

It is important to note that unsanded epoxy-based grout does not require sealant as it is by nature non-porous and thus waterproof and easier to clean than sanded grout. It is also extremely durable. Epoxy-based grout may have its advantages but it can be expensive and it tends to look artificial.<\/strong><\/span><\/p><\/blockquote>\n

Types of Grout Sealer<\/h3>\n

With the seemingly endless amount of companies that manufacture grout sealers, it comes as no surprise that there are a lot of different formulations to choose from. There are water-based varieties as well as solvent-based ones but there are two main types of grout sealers that are worth noting first. These are membrane-forming grout sealers and penetrating grout sealers.<\/p>\n

\"Tile<\/p>\n

 <\/p>\n

Membrane-forming Grout Sealer<\/h4>\n

Membrane-forming, sometimes called surface coating grout sealer is ideal for areas that require moderate protection like a kitchen sink splashback or floor tiles. However, surface coating grout sealers are less ideal for areas that are exposed to excessive moisture and steam such as bathrooms. It would be best to apply a penetrating sealer to these areas. The downside of membrane-forming grout sealer is that it can go cloudy after time and requires reapplication more often than penetrating sealer.<\/p>\n

 <\/p>\n

Penetrating Grout Sealer<\/h4>\n

Penetrating or impregnating grout sealer is ideal for maximum protection against excessive moisture. Penetrating grout sealer is true to its name, in that it penetrates the surface of the grout, unlike surface coating sealer. This type of sealer is not only more effective but also lasts longer as it only needs to be reapplied every three to four years. There are some penetrating grout sealers on the market that can add a color tint to your grout. This is a great way to protect your tiling as well as cover up existing stains or increase aesthetic appeal.<\/p>\n

 <\/p>\n

Water-based and Solvent-based Grout Sealers<\/h4>\n

When we talk about water-based and solvent-based we are referring to the carrier of the actual grout sealer. The carrier, be it water or solvent, will evaporate as the grout sealer dries, this in effect, will seal the grout. Generally speaking, solvent-based grout sealers can penetrate much deeper into surfaces than water-based grout sealers. However, with the scientific development of various formulations, most water-based sealers penetrate deep enough as grout tends to be very porous as it is.<\/p>\n

\"How<\/p>\n

The upside of using water-based grout sealers is that they are generally lower in VOCs. VOC stands for volatile organic compounds. Solvent-based grout sealers contain more of these compounds which are bad for the environment as well as human health. This being said it is advised that you opt for a water-based sealer but if you are going to use a solvent-based sealer be sure to use protective gloves and a respirator. It is also wise to make sure that the room you are working in has some windows and doors open to increase ventilation.<\/p>\n

How to Clean Old Grout<\/h2>\n

Sealing grout is one thing but what if you have neglected the chore for too long and you are now dealing with dirty, stained, molded, or bacteria-infested tile grout? Applying grout sealer over old dirty grout may lock in the dirt or prevent proper adhesion of the sealer. It goes without saying, it is best to clean old grout before applying grout sealer.<\/p>\n

Read on to find out more about the different methods for cleaning grout effectively.<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

Scrub with Hot Water<\/h3>\n

It is best to start with some hot water. Hot water can help loosen some of the surface grime, thus making it easy to remove. Spray the grout lines with hot water and then use a scourer or a toothbrush to scrub the grout before rinsing the area and moving onto the next method if necessary. Using a steam cleaner is a more effective alternative to this method.<\/p>\n

\u00a0<\/strong><\/p>\n

Bicarbonate of Soda and Vinegar<\/h3>\n

Mix bicarbonate of soda with water to create a paste. Use a toothbrush to scrub the grout with the mixture and leave it to sit for a few minutes. Next, using a spray bottle, spray distilled white vinegar onto the bicarbonate of soda. It will start to fizz and bubble as a chemical reaction takes place. Continue scrubbing the grout with a toothbrush or scourer to remove the dirt and grime. It is wise to thoroughly rinse white vinegar from tile grout as it can be corrosive over time.<\/p>\n

\"Best<\/p>\n

 <\/p>\n

Oxygen Bleach<\/h3>\n

If you are battling tough stains on your grout you can try some oxygen bleach, also called sodium percarbonate. This product is not as toxic as household chlorine bleach but it is still wise to use it with caution. Before using oxygen bleach, it is best to read the manufacturer’s instructions. Be sure to use it in a well-ventilated space. You will need to leave the formula on the grout for about 15 minutes before rinsing it with clean water.<\/p>\n

 <\/p>\n

Bicarbonate of Soda and Hydrogen Peroxide<\/h3>\n

Another concoction that can be very effective in removing dirt from gout is bicarbonate of Soda and hydrogen peroxide. Mix the two, one-part hydrogen peroxide to two parts bicarbonate of soda to create a paste. Add a dash of dish soap to help fight oils and grease. Apply this paste to the grout lines and let it sit for about 15 minutes before scrubbing with a toothbrush or a scourer and finally rinsing thoroughly with water.<\/p>\n

This combination of ingredients should restore your old grout lines to their former glory.<\/strong><\/span><\/p><\/blockquote>\n
