Ceramic and porcelain tiles are artificial building materials made of clay, with a nice colored layer then a glaze layer in the top. The alternatives in clay types – the bisque layer – is different from ceramic to porcelain. If it’s red then it’s definitely a ceramic tile, ceramic is weaker and has more pores than porcelain.

Porcelain is treated by firing process to increase it strength in order to resist scratching and water absorb. Porcelain types are veneer surface, full-color and full-body porcelain. Veneer is just a thin top printed layer with off-white color bisque. Full-body porcelain has colored bisque layer, usually it has different colors to form particles or to have veins like style. Full-body tiles is allowed to surface grind for maintenance, also if the surface scratch the body has the same texture. Full-color porcelain is a cheaper alternative, it has two layers, the top surface is printed and bisque has color similar to surface texture.  

Last several years, when tiles’ production bloomed. The tiles have more textured finish alternatives ranging from shiny, soft reflection, rough and in addition to 3D geometric tiles. As a trend, designers use the tiles that similar to wood, natural stones and concrete like tiles. Porcelain production’s developed to have products that are similar to natural materials in texture, reflection and seamless tiles prints.

Some tile’s designs have several 3D forms to create a more natural and realistic appearance. Rough and 3D surface tiles are not suitable for floors, where it’s hard to clean. Rough and 3D geometric tiles designed for a wall decoration. Use 3D geometric and rough tile to create a focal point by applying a graze light to it. This idea suite small spaces like toilet and bathroom. For rough surface tiles use a defined boundary wall that doesn’t have openings or fixtures to avoid bad connections.

Ceramic and Porcelain Tiles Printing

There are two methods of tiles printing, the printing veneer and full-body casting types. In both methods, it’s always better to have different printings. The different prints will have a more natural appearance, four and more seamless prints will increase the tiles price. Full-body casting will definitely have seamless tiles, since it’s casting the mix could have slightly different tones. The different tones will look ugly next to each other, each tile package has a tone number, keep an eye on that. To reach economical casting solutions, producers created combination type of porcelain. The combination by casting the top surface at porcelain bisque. The combination type porcelain is the tiles manufacturing trend, the tiles casting is in competition to veneer printing tiles price.

Ceramic and Porcelain Tiles Reflection

Ceramic and porcelain tiles has glaze layer, this  glaze layer could be matt, slightly reflect or high glossy.  The traditional shiny tiles that have a high gloss became timeless. The matt and rough tiles’ finish took it place to look similar to natural materials. 

Porcelain manufacturing contain the firing process, this by applying a high temperature to porcelain. Firing process give the glaze layer strength to resist scratching and fill the surface pores to be a waterproof layer. The porcelain fire process disadvantage is that glaze layer will wave. The waving will appear more in high glossy tiles, and decreasing in less shiny surface and won’t appear for matt surfaces.

Matt tiles suite lighting design more than glossy tiles. When light source reflect at glossy tiles will it mirror the light source gives visual noise. Designers use matt and rough tiles that doesn’t reflect light, to have a visual comfort.  The only problem face matt and rough tiles is cleaning, where the rougher the surface is, the harder to clean it surface. Therefore we prefer not to use at floors. But also keep in mind that a high gloss tiles is hard to clean, it has always to appear elegant and shiny.

Everything you need to know about Tiles Grout

Grout is tiles joint – small space – between tiles, this space function is to allow the craftsmen to align tiles together. Typically spaces between tiles range from 2 to 4 mm and it measured by plastic grout spacers.

The size of tiles joints can affect the tiles style either modern or classic. For modern appearance usually we recommend arrangement tiles directly with no space. This fit laser cut tiles case, where tiles are well trimmed at 90 degrees angles. On the other hand, saw cutting tiles will have classic appearance. Saw cutting tiles are cheaper than laser cutting tiles, but during manufacturing it could have a difference in tiles size. This could appear clearly by eyes therefore it’s better to use large tiles joint about 7 mm wide. However in classic appearance tiles it more beautiful to leave a large grout space, but be aware to buy a good brand ground to avoid color changing.

Grout function is to align tiles together and it’s not expansion joints, because it could fill by cement grout or in marble tiles cases could fill with epoxy or marble adhesive. Both fillers type could be colored to appear in harmony or in contrast with tiles.

As expansion joint we recommended to leave around a cm between tiles and walls. The expansion joint will cover by tiles’ skirting. Expansion joints need to be clear from sand and mortar, then to fill with highly stretchable material like Sikaflex. Then it covers with tiles skirting.There is a special accessory for tiles expansion joints where it installed outdoors in high temperature countries.

According to ISO standards 13007, where grout classified according to materials to resin grout RG and cement grout CG. The cement grout classify to CG1 and CG2, of course CG2 is better. You can search about Iso standards 13007 for more information. Notice that there are few other factors affect grout quality. For example, the tile joint has to be clear from sand or dust, so the grout find a place it self. 

Cleaning Tiles Grout

Many people suffer from tile grout cleaning, especially floor cement grout. For cement grout, where cement has pores that could collect dust and dirt. Then the cement grout will become darker and look old. There are some chemical products that clean cement grout like Grout Cleaner from Fila. It will clean the cement pour from dust and dirty then partly close those pour. Designer sometimes use dark color cement grout, in order to protect it from color difference. Compared to epoxy or using marble adhesive as tiles grout, where it has less pour that won’t collect dust and dirt. The epoxy and tile adhesive grout is using only in indoor where sun will fragment it, making creaking and disassembled with walking friction.
