• Flexion-compression: CONTROLS MCCC66 • Detachment: BRAIVE DYNATEST

• NOTE: The product exceeds on average the statutory requirements for C1 adhesive by 95%.

PROPERTIES


Cementitious white ceramic tile adhesive with minimal slip. Provides high bonding power, resists moisture and quickly acquires its mechanical strengths.
Classiffied C1 per ΕΝ 12004. (MIRTEC/Cert. No. 3351).

APPLICATIONS

SPECIAL MONOCOTTURA is suitable for indoor wall and floor tile installations. The addition of DUROSTICK ACRYLIC EMULSION in the mixing water, at a ratio of 1:1, improves its technical characteristics, to meet the requirements of C2 class (improved cementitious adhesive) per ΕΝ 12004 and S1 class (deformable adhesive), per ΕΝ 12002. The impoved adhesive then becomes suitable for outdoor installations, even for low absorbency tiles.


USE



1. Surface preparation
The application surface have to be sound, clean, free of loose materials, dust, paint, grease and oil. The surface have to be soaked before the application. It is necessary to prime all absorbent substrates and aircrete, using DUROSTICK ACRYLIC EMULSION or D-20, at a mixing ratio of 1:1 with water.
It is necessary to prime all drywall using DUROSTICK micromolar stabilizer, AQUAFIX or SOLVENT BASED PRIMER. Lightweight or else, unstable cement screeds, must necessarily be primed with DUROSTICK ACRYLIC EMULSION or D-20 at a ratio of 1 part additive to 2 parts water or 1 part DUROMAX to 5 parts water. Follow all balconies, terraces applications by coating the substrate with HYDROSTOP FLOOR, with 2-3 successive, crosswise layers to ensure the waterproofing of the substrate.


2. Application
Empty the adhesive into a clean container with cool water at a ratio of 2 parts water to 5.5 parts powder (6-6.5lt water to 25kg powder or 1.2-1.3lt water to 5kg powder) and mix with a low speed, electric mixer until a lump free, homogenous mass is created.
Allow the mixture to mature for 5-10 minutes. During use mix periodically, without adding extra water.
Apply the adhesive using a notched trowel, and spread on the substrate.
Then, coat as much surface as is required to work for the next 10-20 minutes (depending on weather conditions), thus avoiding skin formation. Finally, install the tiles in the selected position by tapping softly with a rubber mallet.


CONSUMPTION

3-5kg/m², depending on the size of the notch of the trowel, the smoothness of the substrate and the dimensions of the tiles.

 

STORAGE


Store in tightly closed packages, in dry and shaded places for a minimum of 12 months after production date.

SAFETY DIRECTIONS

The product contains Portland cement. Before using, refer to the cautions on the product’s package or the Material Safety Data Sheet.

PACKAGING


Carton box with 4 pcs. of 5kg each one
Paper bag of 25kg on 1,500kg pallet

CLEANING

Clean all tools with water, immediately after use.

ΝΟΤΕ:

On outdoor surfaces, it is highly recommended to create expansion joints every 16-20m². Prime the expansion joints with PRIMER-PU, to improve grip, and seal them with the polyurethane sealant, DUROFLEX-PU. Similarly, seal all the joints (5-8mm) at the junction of the tiles and vertical surfaces throughout the perimeter. Alternatively the application of DS-POLYMER, in 32 shades (same with the grout colors of DUROSTICK), ensures sealing without cracking at the junction of the tiles with the skirting and above it as well.
