Tilers usually apply a thin coat of sealant to the tiles before they lay them and it helps them to remove unwanted grouting haze, which is the messy part of installing tiles and can be very difficult to clean.
Sealant may be used by home owners who struggle to keep their grout lines clean, or who have a habit of spilling staining liquids such as wine, coffee, food or even mud that’s brought in from outside. Although the sealant does not stick to the smooth porcelain surface, it quite happily solidifies in the porous grout. Any liquid that falls on top can be wiped off without too much effort.
Because grout is the deepest part of the tile, dirt often settles in these grooves regardless of whether or not it has sealant. And sometimes the dirt might cling onto the sealant instead of soaking through to the porous grout (the purpose of the sealant) and the only way to remove the dirt is to remove the sealant too. So most tile cleaning services start by stripping anything that could be trapping dirt to the tiles and grout. This stripper is a high alkaline solution and harmless to most tiles, even stone. Stripping solution is corrosive to wood and vinyl and should be kept well away from these softer furnishings.
Although tile cleaning companies cannot offer any guarantee on the sealants ability to keep tiles clean, impregnating sealant can be very expensive and the cost of applying these products is usually priced at half of the cleaning service.
So you can see there’s no harm in sealing porcelain tiles, it just depends on whether or not the customer would like to invest in something that might, or might not, work.
