Do Porcelain Tiles need to be sealed?

Porcelain tiles are extremely hard wearing and make a great choice for anyone looking for an outdoor patio that will last for a very long time, whilst maintaining its finish without scratching or fading.

You may be wondering if there is any maintenance or preparation that has to be done when installing porcelain tiles on either a mortar bed or a suspended aluminium system, and rightly so! If you were using natural stone you will have to stain and seal it at least on a yearly basis to prevent algae, stains, and damage to the tile in general.

However with a porcelain tile, there is no staining required at all to the top surface. It is a non-porous material so will not be affected by water or stains. There is no way for the liquid to penetrate the tile, meaning it will clean up very easily.

When installing your porcelain tiles on to a traditional mortar bed, you will have to prime the bottom of the tile using a porcelain prime. The reason for this is that it helps the tile to bond to the mortar. If you do not prime the underside, the tile may come loose over the coming years after being installed.

A great benefit of using a raised aluminium support system to install your porcelain is that there is no primer or sealant required. The porcelain sits straight on to a rubber gasket running along the rails and can be installed straight away, no waiting for any primers to dry overnight or having to worry about the weather!
