There are many types of sealers on the market, and it can be difficult to decide which one to use. Some factors you may want to consider when choosing a sealer include the type of natural stone you have, how porous it is, and what type of finish you want. Some popular sealers include concrete sealers, acrylics sealers, and epoxies sealers. Each type of sealer has its own benefits and drawbacks, so it's important to do your research before deciding which one is right for you.

Unfortunately, there is no easy answer to this question. The best sealer for natural stone will vary depending on the specific type of natural stone that you are trying to seal. Some general guidelines that may help include using a penetrating sealer rather than a topical sealer, and choosing a sealer that is made specifically for natural stones. You should also test the sealer on a small area of your natural stone before applying it to the entire surface.
