Application Information
Instructions for use

Surface preparation

All surfaces should be sound, clean & uncontaminated.  This preparation should leave an exposed concrete surface free from dust, loose particles, deleterious matter, oil, grease, chemical film & other contaminant.

All loose particles of mortar, paint, etc. must be physically removed.

Cementitious substrates must be not subject to shrinkage once the tile is been installed. Allow substrates to cure for a minimum of 21 days. The surface of substrates must be moistened slightly with clean water to reduce the absorption of water from the mortar.  Do not moisten the tiles.


MAXICOL T50 should be mixed with clean water (about 4 to 4.5 Liters per  bag of 25 Kg). Mix it carefully with a mechanic mixer at low number of turns (200 - 300 turns per minute) till a uniform lump free consistency is achieved. Remix briefly before application.


Pour MAXICOL T50 product onto the surface and spread to the desired thickness using steel trowel or suitable tool.

Place the tiles onto the adhesive bed. Apply sufficient pressure on the tile during fixing with slight twisting movement in order to ensure good contact with the mortar.

In case of large size tiles, it is necessary to spread the adhesive also to the backside of the tile and then place the tiles into the adhesive bed.

Apply enough material that can be tiled during the adhesive's open wet time. Spreading large areas may result in drying the adhesive before tiles can be fixed causing poor adhesion.


Remove excess adhesive with damp cloth before the material has set.  Joint grouting between tiles may be commenced 24 hours after tiles are laid on the floors.


Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.


  • Stiffened mortar must neither be diluted with water nor with fresh mortar
  • Do not use MAXICOL T50 on metal, wood or non-absorbing surfaces
  • Do not apply MAXICOL T50 in rainy weather, high winds and sand storms
  • Do not use to stone material subject to efflorescence or staining
  • Do not apply under direct sun
  • Keep equipment cool and use cold water
  • Porosity of tiles and substrates has significant effect on adhesive strength of tiles
Additional Information
Health & Safety

MAXICOL T50 can be harmful to skin as it contains cement powders which may releases alkalis when mixed with water.

During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.

In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.

If ingested, obtain medical attention immediately. Do not induce vomiting.

Monneli Primer A16

Synthetic Resin Primer

PRIMER A16 is used for the preventive treatment prior to laying of ceramic tiles with the cement adhesive on gypsum boards. Such application on the supports avoids the chemical reaction between the gypsum sulphates and the cement aluminates contained in the adhesives for ceramic tiles, which in case of humidity presence could provoke breakaway of tiles.
It can be also used at gypsum or very porous supports before painting with acrylic or vinyl paints, to avoid too fast drying.
PRIMER A16 is used on light weight plaster and other porous surfaces such as asbestos boards, on wood, hardboard, chipboard, and so on, before fixing ceramic wall and floor tiles in the usual way.
