Have you ever wondered if applying granite sealers makes your material durable and look great? However, improper cleaning or neglected spills can decrease granites’ shine. Granite sealers are full of controversies because many people do not know when to apply granite sealers or how their sealing works. A simple test for granite sealing can give you all answers that you are looking for. Proper use of these can make your marbles look flawless. So, here is detailed information about how to apply granite sealer like a professional.

Things Required to Consider Before Sealing a Granite

Before anything, let us know about what things are necessary to consider before going for sealing granite.

  • Most of the standard ones currently available protect the material against water or oil stains to some extent.
  • Besides, always go for non-toxic products that are free from harsh chemicals. It is because such chemicals can irritate or impart strong odors. Instead, look for gentle yet effective sealers.
  • For getting the best results, purchase carbon resins sealers because they provide good protection. However, they could be a little bit expensive.
  • Additionally, one can use both water-based and solvent-based sealers, but water-based ones are easier to apply and environment-friendly.

How to Apply Granite Sealer? – Systematic Procedure

Granite countertops are very easy to seal and the process is simple. All a person has to do is read the instructions thoroughly before applying them. Step by step process for how to seal granite with a sealent is as follows-

  1. Test your granite countertop very crucially to determine if it requires sealing.
  2. Later, clean it using acetone or any quality granite cleaner available so as to remove any debris or residues accumulated in it.
  3. Now, carefully apply the sealer onto your granite countertops so that you cover every small area.
  4. Using a paintbrush, create a thin film sealer around it.
  5. After applying it, allow the sealer to get absorbed for about 2-5 minutes.
  6. To cover the full area, ensure that your sealer absorbs and the area gets dry. Let it sit for around another 2 minutes.
  7. Finally, wipe the area with a dry cloth to remove any excess sealer.

Tips for Applying a Granite Sealer

Sealers, which you are applying, should get absorbed for effective results. Otherwise, if it does not dry properly, it will leave a stain on your granite counterpart. Then, you can go for pouring or spreading the sealer rather than wiping or spraying it.

  • Remember to not wipe the sealer immediately after spraying it because this will not seal the countertop. It will be a total waste of time and money.
  • It can work if you apply the spray on a repetitive basis until it creates a thin film.
  • The same thing will happen if a soaked cloth is wiped around the surface, so excess sealer does not stay on that stone surface.
  • A stone sealer must be absorbed properly to get effective results to saturate the marble. Ultimate goal is to create a thin film sealer.
  • If you see the surface hazy, after pouring the sealer, rub it with a cloth and wipe that specific area completely dry. Spots will disappear after this application. It will become difficult if you wait for a longer time or if the residue from the sealer is completely dried up.
  • If your granite colors are light, you may require a second or third coat, especially on white granite countertops.
  • For testing the efficiency, perform the granite water test after 30 minutes of your first coat. Water takes a long time to get absorbed after each coat. Sealer gets effective when water takes more than 20 minutes to get absorbed.

How Often Does Granite Need to be Sealed?

This purely depends on what is used to seal granite countertops. If it is a imregnanting sealer it may last long. Variability by which granite sealers are re-applied depends upon-

  • The rate at which sealers get absorbed into a stone surface,
  • Your granite’s type and quality,
  • How effective you have applied the sealer,
  • The products that you’ve used to clean your granite countertops.

Factors Deciding How Often to Apply a Sealing on Granites

  • Those who own white granites that are unpolished and have light colors will have to seal every 1-3 years.
  • Dark-colored ones or polished marbles require sealing for every 3-5 years. However, it completely depends upon a particular marble’s quality. By performing a water test, one can test their marble‚Äôs effectiveness.
  • Porosity of a stone is another factor to consider. It is important to remember that we should apply the sealer in multiple coats and not wipe it immediately.
  • Normal impregnating sealers break down after several months. Thus, a repetitive application is preferable. However, permanent sealers require only one application.

What is the Best Sealer for Granite?

Everybody wants an impregnating stone sealer rather than a topical one. Using a longlasting one is always best way to seal granite countertops. Besides, granite’s look and texture will depend on which type of coating a person chooses to give. Standard impregnating sealers do not form any permanent bonds over a particular stone on which we are applying, so it is essential to apply them every 1-3 years. Whereas re-application completely depends upon the porosity and quality of a granite stone.

So talking about re-application, there are common yet best sealers that require re-application, such as DuPont, Marble life, Rock Doctor or Aqua Mix, and many more. However, if you want to seal the stone permanently, then you will have fewer options. Some of them are-
