The high resistance to stain and easiness to clean allows it to use in a lot of applications.
Fixing slates
We recommend you to use glue from good quality. We suggest glue above cement because slate has a low absorption percentage. For more information ask your glue producer which glue you should use considering the dimension of the slate and the floor foundation.
Sealing slates
Our Brazilian slates have very low absorption percentage and a high resistance to stain. However, we can recommend the use of a surface treatment, it will enhance the color and protect your floor.
Before you apply the treatment, the slate needs to be perfectly clean and dry. It is recommended to follow the suggestions of the sealer producer, you should apply a good quality sealer.
Cleaning slates
To clean natural stones it is recommended to use dedicated products. Sealed natural stones can be cleaned with water.
