Should I Seal my Porcelain Tiles?

Should I Seal my Porcelain Tiles?

Sealing tiles is a common practice in order to protect them and it also makes it easier to carry out regular maintenance. But actually there is not common agreement about whether to seal or not, and some say that matt or textured tiles should be left untreated altogether. If you are not sure whether or not you should seal your porcelain tiles, here we tell a bit more about you to help you make the decision.

Why Seal Tiles?

Sealing helps to make the tile stronger by helping to protect against dirt, spillages and erosion. There are some tiles where you don’t have a choice and you really do need to seal - this is the case with stone. Stone is naturally porous and will absorb spills and stains fairly easily. In general we tend to think that tiles don’t absorb water, however even the strongest tile can have its micro-pores open when polishing the surface, and therefore the sealer ends up being quite helpful.

Can I Leave Porcelain Tiles Unsealed?

We previously said that with some tiles you are left no choice but to seal them; well porcelain is not one of them. Porcelain is a very hard wearing tile and resistant to liquids so it is much stronger and can survive being untreated. They are available in glazed or unglazed and baked under high heat, making them very hard and often highly resistant or impervious to liquid stains. As you can see, porcelain is already strong enough by itself, but you can always add a penetrating sealer to fill the micro pores on the surface of the tile if you wish. However, the grout joint between the tiles is usually very porous and generally made of a cement-based material.

We have said the grout is very porous, so even if we are saying you don’t need to seal the tile, this doesn’t mean you shouldn’t consider sealing the grout. If you are confused, you just need to know that the tile and the grout are two different parts of the tile floor with different properties and water resistance. Most of the floor is made up of the actual tiles but the grout is just as important. It is the often overlooked material that holds the tiles in place. It is naturally porous and will stain easily, and sealing it will allow you to keep your grout looking always good. In addition sealed grout is more hygienic and much easier to keep clean.
