FIXING TILES IN VERY HUMID AREAS

 
ADVICES PREPARATION APPLICATION FINISHING

How to deal with constraints such as high pressure water jets, permanent running water and aggressive cleaning?

• Public showers (e.g.: stadiums, gyms, etc.)

• Public kitchens and toilets if cleaning with high pressure water jet (> 60 Bars)• Industrial laundries

• Aquatic centres, balneotherapies, swimming pools (not including basins).

 

Recommendations:

It is important to ensure the appropriateness of the substrate-adhesive-covering.

Water proofing the substrate is strongly recommended on intermediate flooring.

Water proofing is obligatory if the covering on the other side of the partition is water sensistive.


SUITABLE SUBSTRATES:

• FLOORS: concrete, mortar screeds.

• WALLS:

- concrete, mortar finishing coats.

- Untreated terra cotta tile partitions (cement built), providing certain precautions are taken (see table).

 

LEVELLING OF UNEVEN SUBSTRATES

• When directly bonding to the substrate, all of DESVRES adhesive mortars can be used to level off localised uneven areas between 6 and 10 mm deep (depending on the product), the day before fixing the tiles. See Technical Data Sheet.

 

• Use RAGRELISS + CERMILATEX or MORTIER 350 + CERMILATEX on walls and floors.

 

WATER PROOFING OF SUBSTRATES

Water proofing is recommended in many cases on intermediate flooring: use CERMIPROOF and CERMITANCHE under tile liquid water proofing systems, combined with AT 75 reinforcement strip (cf. Technical Data Sheet n° 310) or PPE water proofing membrane.


FLOORS Concrete - cement based screeds

- Direct bonding to the substrate: Cermisol, Cermigrés, Cermitex, Cermiplus, Cermiplus rapid, Cermifloor N, Cermifloor HPR, Cermifloor rapid, Cermiflex ALG, Cermidur (2)

- Water proofing: Cermitanche, Cermiproof, Membrane PPE (use Cermiplus/Cermidur/Cermfloor /Cermiflex ALG for fixing the tiles)

 

WALLS Concrete

- Direct bonding to the substrate: Cermigrés, Cermitex, Cermiplus, Cermiplus rapid, Cermiflex ALG, Cermidur,

- Water proofing: Cermicryl*, Cermitanche*,Cermiproof*, Membrane PPE (with Cermiplus/Cermiflex ALG/ Cermidur for fixing the tiles)

 

WALLS Cement based finishing coats

- Direct bonding to the substrate: Cermicol extra, Cermidal, Cermigrés, Cermitex, Cermiplus, Cermiplus rapid, Cermiflex ALG, Cermidur,

- Water proofing: Cermicryl*, Cermitanche*,Cermiproof*, Membrane PPE (use Cermiplus/Cermiflex ALG/ Cermidur for fixing the tiles)

 

WALLS Terra cotta tile partitions (cement built)

- Direct bonding to the substrate: Cermigrés, Cermitex, Cermiplus, Cermiplus rapid, Cermiflex ALG, Cermidur,  (1)

- Water proofing: Cermicryl */ Cermiproof*, Cermitanche*, Membrane PPE (use Cermiplus/Cermiflex ALG/Cermidur for fixing the tiles) (1)

(1) Water proofing obligatory if the covering on the other side of the partition is water sensitive.

(2) In certain cases: paving, bond breaking substrates, standard adhesive mortars may be used for fixing the tiling.

* Recommended


JOINTING: for the jointing, use: CERMIJOINT TX (if necessary, admixed with CERMILATEX), CERMIJOINT HRC, EPOGLASS/EPOSOL

 

CLEANING OF JOINTS

• Use KITAJOINT
