The test requires 5 tiles.
Ceramic tile water absorption.
All grouts except epoxies will allow some moisture absorption.
Only vitreous and impervious tiles should be used outdoors or in.
For exterior applications the selected tiles should have a low water absorption rate especially in climates subjected to heavy rainfall and freezing and thawing cycles.
If you take the 2 tiles flip upside down and sprinkle water on them.
Tiles can be differentiated according to their water absorption into 3 types as follow.
This may seem like just another characteristic on the list of specifications but it is more than this.
The water absorption percentage reflects the density of the tile body.
In fact it tells us that the ceramic.
A mere 0 5 in the case of porcelain tiles compared with 6 for stoneware ones groove by keraben.
Water absorption is also directly related to the suitability for interior or exterior applications.
Glazed tiles are resistant to water at the tile surface but susceptible at the edges.
For exterior applications the selected tiles must have a very low water absorption rate as close to an impervious rating as possible especially in climates subjected to rainfall freezing and thawing cycles.
Absorbent value between 0 5 3 e g.
Absorbent value less than 0 5 e g.
The samples are first dried at 150 c for 24 hours and then boiled for 5 hours to replace air bubbles from the open pores.
Ceramic will absorb the moisture like a sponge but will only bead up on porcelain.
Absorbent value more than 3 e g.
Porcelain tiles have a far lower water absorption rate than glazed stoneware tiles for example.
The water absorption rate is directly related with the suitability of the various types of tile for interior or exterior applications.
Wet areas such as a shower or steam room should have porcelain tiles.
Suitable for all interior and exterior uses.
