Mosaic - Cleaning and Sealing

The term "Mosaic" really refers to how small pieces of tile are installed in designs, more than the actual composition of tile pieces.

Mosaic tile are treated the same way as the larger porcelain tiles.  They are the same hard fired material and color all through the body and are generally not glazed. Typically small (1" square) square, hex, rectangle with a mesh backing for easier installations.

Glass tile fit the same description with the exception that they are glass and not porcelain. Both types are treated the same way and are referred to as mosaic tile herein.

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.
  • Small size provides traction created by the close spacing of the grout joints.  Therefore, considered beneficial for wet area safety.
  • Used to create artworks for centuries by placing one tile at a time. Now, they come pre patterned on mesh backing and are as fast and easy to install as regular tile.
  • Even if the tile is so smooth and dense that it does not need to be sealed, the grout does need to be sealed.  See below.

  • Dense, hard, tough
  • Comes in a wide variety of colors and textures.
  • Close grout joints provide slip resistance.
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.
  • Efflorescence (subsurface originating white powdery stains) can occur but usually from the grout as this tile type is too dense for water transmission. This can appear anytime and is easily cleaned.
  • Grout can have light efflorescence, but that can be stopped by sealing with the appropriate Aldon sealer.

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.

Typically, Mosaics do not need to be sealed, but may benefit from a surface coating to impede dirt collection and improve ease of cleaning. Aldon

 "Tile Cover" will provide this surface coating without changing the tile appearance. However, first the grout must be sealed. See sealer recommendations below.

For the higher textured mosaics, a technique to fill and seal the surface is to seal the tile and grout with Aldon

 "S-B-S Sealer". This will usually create a light gloss on the tile face. If desired, this gloss can be removed with lacquer thinner so that the end result is a filling of the pores without creating a glossy finish.


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!)
