Tiling Tips


Finishing Strips

Finishing strips are a great way to neatly handle exterior corners and stop-ends.  

The 8” Finishing strips are sized to work with the thickness of  4x4”, 6x6", 8x8”, 4x8” and 4x12” tiles. The 12” Finishing strips are sized to work with the thickness of  6x16", 8x24” and 12x24” tiles.  


Importance of Grout Joints 


It is important that Johnson Tiles, as with all wall tiles, are installed with a grout joint - typically  1/8” -3/16”. The slight raised edge of the tiles is NOT a lug; it is designed to separate tiles in the kiln Therefore the use of tile-spacers to provide a uniform joint is recommended. Where tiles are butt jointed as well as for aesthetic considerations (any slight bowing , or lippage will be exaggerated ) , movement in the substrate that might otherwise be taken up by the grout joint may create cracking or crazing.



Johnson Tile wall tile series are tested for craze resistance prior to launch and conform to recognized standards. Crazing, the spider like cracks in the glaze developing after installation reflect stresses in the installation, usually occurring due to movement. This can occur for a variety of reasons

  • walls are not flat 

  • tiles are not jointed

  • movement in the substrate

  • excessive moisture entering the tile body

  • the setting material not used in accordance with manufacture instructions and recognized codes of practice.


Some reports indicate that if an extremely high bond adhesive is used, often in too thick a bed, the setting of the adhesive can cause the tile to slightly bend and then result in crazing of the glaze.

However, the most common reason is that crazing is a natural occurrence in some installation environments and is an inherent property of ceramic and porcelain tiles, and is not detrimental to the performance of the tile.

William May cannot accept claims defining crazing as a reason for product failure. 

Types of Lay Patterns


With the popularity of rectangular tiles, a choice has to be made as to how the tiles are to be installed, stacked, bricked, herrringbone, 1/3 bond are popular examples.

All Johnson Tiles are tested for flatness , straightness of sides and rectangularity and fall within recognized industry standards.  That does not mean tiles are perfectly flat but great care is given to produce tiles of world-class quality,  The finished look of the installation  is influenced by lighting placement , grout -joint , flatness  of the substrate  and tile size. It is always advisable to dry-lay or tile a small  area in order to gauge satisfaction before full  installation, particularly where  a 1/2 brick-bond is under consideration In some instances, where lighting particularly is adversely affecting the look of the installation , a 1/3 joint can provide a safer and pleasing option.
