Mapei Kerafloor tile adhesive

Kerafloor is a cement based powder adhesive for ceramic tiles (thicknesses of adhesive up to 15 mm).

Where to Use

Interior and exterior bonding of tiles and strip tiles (gres, klinker, single fired) with high lugs and ribs.
Interior and exterior bonding of tiles (double fired, single fired, cotto toscano, hand-made) and also where they are of various thicknesses or twisted

Example Applications

Installing extruded klinker tiles or tiles with deep recessed backs on ordinary renders and substrates
Installing large-size double-fired and single-fired tiles (over 30×30cm) in interiors on cement substrates
Installing natural stone and ceramic tiles with large thickness variations on ordinary substrates
Installing ceramic tiles on irregular substrates with beds up to 15mm thick without preliminary levelling

Technical Characteristics

Kerafloor is a grey or white powder composed of cement, silica sand with particularly large grain sizes, synthetic resins and special additives.

Mixed with water, Kerfloor becomes and easily trowellable mortar that can be used on both horizontal and vertical surfaces. Kerafloor hardens without significant shrinkage and without reductions in thickness.

It becomes very resistant and adheres perfectly to all conventional building materials.

Kerafloor mixed with Isolastic in substitution of water, improves charactersistics to meet the requirements of class C2 (improved cementitious adhesive) according to EN 12004.

Recommendations

use Kerfloor mixed with Isolastic in the followin cases:

on foamed concrete walls
on precast concrete structures or cast in situ
on underfloor heating installations
with large-size tiles on substrates subject to movement

Do not use Kerafloor in the following cases:

for installing stone material subect to movement due to moisture
for installing stone material subject to efflorescences or stains
on wood
on metal, rubber, PVC, and linoleum surfaces
for installing over existing flooring

Grouting and Sealing

Wall joints can be grouted after 6-8 hours with floor joints after 24-36 hours with the special MAPEI cementitious or epoxy grouts. Expansion joints must be sealed with special MAPEI sealants.

Ready for Use

Surfaces are ready for use after 14 days approx.

Consumption

Approximately 1.4kg of Kerafloor per m2 and mm of thickness.

Consumption depends on substrate conditions, on the type of tiles and on the trowel notches and generally varies between 4 and 10 kg/m2.
