Porcelain Tile - Cleaning and Sealing
"Stone Look" textured face

Porcelain tile are not a glazed tile. They are the same extremely hard, durable, nonabsorbent material all the way through. The smooth tile face finishing process creates microscopic open pores (micro pores).

"Stone Look" has stone texture and colors pressed into the face.  its needs are discussed here, however, see the "Stone Look" tile page because "Stone Look" tile can be made from other materials than porcelain.

There is no need for confusion or problems brought about by misidentification of a surface type, yet it happens all too often. If you would like to see why this is the case and how to properly identify a surfacing material ..... Click here

If you are concerned about doing it yourself - consider that the satisfaction of a project is directly related to your knowledge of what needs to be done and how. Who actually does the work is less important. We estimate that 25% of the usage of Aldon products is by "do it yourself" homeowners and we know they are happy because we hear from them.

  • High fired and very tough and durable.
  • Textured type provides traction.
  • Heavy textures can be improved for dirt retention.  See below.

CONSIDERATIONS      (All Are Preventable!)

(Click links for Aldon's solutions to these issues!)

  • For textured face tile - do not use a sealer as a grout barrier (pre-seal). Prevent grout smears, surface scratching and keep grout residue out of surface texture by coating with Aldon "Grout Easy" before grouting. "Grout Easy" is a water soluble coating that comes off easily while grout is being cleaned up with water and a sponge.
  • If the tile was installed without using "Grout Easy" and you now have a grout haze to clean off the tile face, use Aldon Grout Residue Remover.
  • Efflorescence (subsurface originating white powdery stains) can occur on the grout. However, it is easily cleaned.
  • Grout can have light efflorescence, but that can be stopped by sealing with the appropriate Aldon sealer.
  • Some manufacturers ship their porcelain tile with a coating on the face to ease the grouting process (act as a grout release). The coating materials can vary from weak sealers to greases or oils. These coatings can cause problems after installation and should be removed after grouting. See the Aldon    section for the page Redoing a Previously Sealed Surface! as these factory applied coatings fall within that category.
  • Sometimes porcelain tile will vary from batch to batch in terms of smoothness of finish. If the tile finish or color is uneven or "dull", test Aldon SBS Sealer to even out gloss, enhance dull colors, and seal the grout in the same operation. The sealer's low gloss finish will also make cleaning easier.


Typically, Porcelain tile do not need to be sealed, but they do need surface protection to impede dirt collection and improve ease of cleaning. Aldon Tile Cover will provide these improvements. However, first the grout must be sealed.   See below.

A technique to fill and seal the micro pores (if they exist in your tile) is to seal the tile and grout with S-B-S Sealer. This will usually create a light gloss on the tile face. If desired, this gloss can be then be removed with lacquer thinner so that the end result is a filling of the micro pores without creating a glossy finish.

Following are recommendations for products you may need (in sequence of use ) for whichever of the categories applies to you. Please review each and mark your printed worksheet accordingly.

An Aldon sealer does far more than just bead water and look pretty! To see what that is click here.

Important: If your project has had any sealer applied in the past, it must be evaluated differently. To see why, Click here! To insure a good bond of the sealer to the tile face - be sure to clean off any residual coatings (oils, waxes, sealers) that might come from the tile manufacturer. Usually lacquer thinner will accomplish this.
