Mapei Kerapoxy Adhesive 10kg

Description

Mapei Kerapoxy Adhesive is a two-component epoxy adhesive with no vertical slip, for use with ceramic tiles and stone materials.

Mapei Kerapoxy Adhesive is designed for internal and external bonding of ceramic, porcelain and stone to floors and walls, on all substrates normally used in the building industry.  Mapei Kerapoxy Adhesive is comprised of a two-component, epoxy resin-based, high strength mortar with silica sand and special admixtures. When the two components are mixed together, a thixotropic mix is obtained which can be easily applied, even on vertical surfaces, at a thickness of up to 10mm in one single coat.

Mapei Kerapoxy Adhesive can be used for:

• Bonding of all types and forms of ceramic tiles.
• Rigid bonding of bullnose and special ceramic tile shapes.
• Bonding tiles in fibreglass swimming pools.
• Bonding marble doorsteps and windowsills.

Mapei Kerapoxy Adhesive has excellent durability and resistance to ageing, and features perfect bonding on all types of substrate commonly used in the building industry. It hardens by chemical reaction with no shrinkage, becoming extremely strong.

Recommendations:

• Do not add water or solvents to Mapei Kerapoxy Adhesive to increase workability.
• Use the product at temperatures between +10°C and +30°C.
• The packages are pre-dosed and, therefore, it is not possible to make mixing ratio errors. Do not estimate the quantities when mixing the two components: hardening will be compromised if the catalysing ratio is wrong.
• If residues of the product remain attached to the tiles, use water for cleaning while the residue is still fresh. Use Mapei Pulicol 2000 if the product is hard, or remove mechanically.
• Mapei Kerapoxy Adhesive must not be used for sealing flexible joints or those which are subject to movement (use Mapei Mapesil AC Silicone or Mapeflex PU21).
• Mapei Kerapoxy Adhesive must not be used on wet surfaces.
• Mapei Kerapoxy Adhesive must not be used on dirty or crumbly surfaces.

Mapei Kerapoxy Adhesive Application:

• Preparation of the substrate: The substrate must be well cured, mechanically strong, dry and free from flaking parts, grease, oil, paint, wax, etc. Cementitious substrates must not shrink after laying the tiles. Therefore, during good weather, the curing time must be at least one week per centimetre of thickness, unless screeds are made using a special Mapei binder such as Mapecem, Topcem or with Mapecem Pronto or Topcem Pronto. If these guidelines are not followed, the bond of Mapei Kerapoxy Adhesive to the substrate could be compromised. On ferrous surfaces, rust must be removed by sand-blasting. On gypsum, plaster-board and anhydrite surfaces, we recommend consolidating the surface by applying a coat of Primer EP or Mapei Eco Prim T Plus Primer.
• Preparation of the mix: The two components which make up Mapei Kerapoxy Adhesive are supplied in pre-dosed drums:– part A: grey and white colour, 80 parts by weight;– part B: beige colour, 20 parts by weight. The ratio between the two components is compulsory, and any modification may cause the product to harden incorrectly. Pour the catalyst (part B) into the container with part A and mix well until a smooth paste is obtained. We recommend using a low speed electric mixer to guarantee perfect bonding, and to avoid overheating of the mix which would reduce working times. Use the mix within 45 minutes of its preparation.
• Application: Spread the adhesive onto the substrate using a suitable notched trowel. If the adhesive is used for bonding special tile shapes such as torelli, also fill the gaps on the back of the piece with the Mapei Kerapoxy Adhesive mix before laying. Press the pieces to be bonded by pressing them together to guarantee good buttering. Once set, the bond will be very tough. The surrounding temperature effects the hardening time of the product. At +23°C it remains workable for approximately 45 minutes, and this time reduces as the temperature increases.

Set to light foot traffic:
Floors may be foot trafficked after 10-12 hours at +23°C.

Ready for use:
The surfaces may be put into service after 2 days.
