SikaCeram®-51

GENERAL PURPOSE, CEMENTITIOUS TILE ADHESIVE FOR CERAMIC TILES

SikaCeram®-51 is one-pack premixed adhesive consisting of high resistance cements, selected silicon/quartz mineral charges and specific additives, used as thin bed tile adhesive for permanent fixing of ceramic tiles. It is ready to use with the addition of water.
Suitable for use in hot and tropical climatic conditions.

  • Very good adhesion to most substrates (concrete, cementitious mortar, stone, bricks)
  • Easy to mix and use
  • Excellent workability and thixotropic consistency
  • Excellent bond strengths
  • Single component system

Consumption

Consumption

The consumption depends on the surface profile and roughness of the substrate and on the size of the tiles and the placing technique (simple placing "floating" or back to back “buttering-floating”).
As a guide:
For 1 mm thickness over 1m2 area approximately 1.7 kg of material.
One 25 kg bag will cover approximately 4.9 - 7.3 m2 at 3 - 2 mm thickness.

One 20 kg bag will cover approximately 3.9 - 5.8 m2 at 3 - 2 mm thickness.
Application steps

MIXING

Mix a bag with the necessary, above mentioned, amount of water, using an electric blender with a suitable mixing spiral at low speed, in a clean bucket, and up to obtain a smooth paste free of lumps.
Use a blender at 500 rpm maximum; do not mix at faster rate because of mechanical strength decay of the cured product.
After blending, leave the product curing for 5 minutes in the mixing container and then briefly stir the mix prior to application. The obtained mix results very creamy, easily spreadable and thixotropic.

APPLICATION

SikaCeram®-51 is applied using notched trowel.
The amount of product should be enough to ensure complete wetting of the tiles’ rear. Tiling has to be carried out on fresh glue, exerting an adequate pressure to ensure contact with the adhesive, and thus the perfect bonding. In case a surface film is formed on the adhesive, it is necessary to wipe the trowel on the adhesive layer previously applied. Avoid wetting with water the adhesive already applied, it damages the adhesive.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed
