COFLEX CAJ invisible expansion joints

“Invisible” COFLEX CAJ expansion joints entirely integrate into the 5mm grout width. The profiles in co-extruded synthetic resin are composed of rigid, perforated anchoring flanges and a durable, soft upper surface which is resistant to mildew, bacteria, weathering, corrosion, wear and UV rays. They are are conceived to subdivide large tile bays in ceramic tile flooring. Suitable for indoor and outdoor applications; the profile section provides limited protection to the tile edge. Ideally used in retail shops, hotels, sports facilities and schools. Suggested floor bays: 24800-3/64’’ (16m2).

Dilatation joints COFLEX CAJ installation

INSTALLATION: • Select the profile according to the tile thickness. The movement joint should remain 3/16’’ +/- 1/32’’ (5 +/- 1mm) below the floor elevation. • Apply tile adhesive to the substrate. • Position the movement joint in correspondence with the expansion joints in the underlying substrate. AF: This is not an appropriate procedure. Cutting in to mortar beds or substrates more than 12 hours after a pour is ineffective. • Lay tiles flush against the perforated flanges. • Completely fill the residual space between the profile and tile with grout.
