Water based VS. Solvent based sealers – these are just components in the grout sealer. The water and solvents are simply the carriers of the sealant material. These only last a while which is when the sealer dries up they evaporate leaving behind the sealant to secure the grout. Many people are advised to use solvent based sealants as they penetrate deep in dense natural stones unlike water. But when it comes to grout, water based sealant is the best as it’s porous and water can penetrate through it with much ease.

Some of the disadvantages of these two components is that solvent based sealants sparks off a strong odor which is a bit hard to get rid of. While water based sealants tend to leave water marks which should be wiped out immediately. If you’ve children, a water based sealant is the best to use as its less dangerous.

Different categories of grout sealers

This is a type of sealer with a thin layer that protects oil, dirt and water from entering into the grout. They are further subdivided into two which includes; a permanent sealer and strippable sealer. Just like their names state, a permanent sealer is very hard to remove while a strippable can be removed with much ease. Many contractors recommend use of strippable sealers as they are can be removed easily from the grout surface.

  • Colored grout sealers

Secondly, we’ve color sealers. These work similar to other sealers by preventing oil and water from penetrating into the grout. They have an additional feature which is color that blends well with your tile after applying the sealer.

  • Penetrating grout sealers

Another amazing type of grout sealer is the penetrating ones. They are created in such a way that they can penetrate into the grout surface and then place particles that offers protection to the grout from substances like oil and water. It is as well subdivided into two: oilophobic and hydrophobic. Oilophobic repels both water and oil based substances while hydrophobic rejects water based chemicals only.

NB: of all these three categories of grout sealers, the coatings are more economical than the other two. The color sealers are great for beautifying your floor and house generally while the penetrators are the best to use.
