PROHESIVE PROSET is a rigid set, high quality cement based adhesive
PROHESIVE PROSET is a rigid set, high quality cement based adhesive suitable for most types of ceramic
wall and ﬂ oor tiles including monocottura, bicottura, slate, terracotta and quarry tiles. PROHESIVE PROSET
is suitable for thin and thick bed applications onto rigid substrates only. To produce a resilient adhesive with
improved adhesion, ﬂ exural and compressive strength mix with PROHESIVE PROLASTIC as a total water
All surfaces must be clean, dry, free from dust, grease, wax, oil, laitance, curing compounds, release agents,
paint, coatings, friable material and all other contaminants likely to prevent the adhesive bonding. Cement
render/screeds must be allowed to cure for 7 days, concrete to be left with a wood ﬂ oat ﬁ nish and allowed
to cure for at least 28 days before tiling. Refer to the substrate test guide below for recommended surface
preparation. Certain non-absorbent/ impervious substrates that are suitable for tiling should be primed using
Aqua Blök™ Epoxy Seal. For further information, contact the CTA Technical Department.
Aqua Blök™ Epoxy Seal should be used as a primer over Prohesive approved polyurethane waterprooﬁ ng
20kg of PROHESIVE PROSET powder requires approximately 4.5 liters of water. Add a measured amount
of clean water into a clean container and sprinkle PROHESIVE PROSET powder slowly into the liquid
with constant stirring. Eliminate lumps. Mix to a thick toothpaste consistency. Allow to stand for 5 minutes,
and then remix. The adhesive is now ready to use. Prohesive PROLASTIC must be used as a total
water replacement in areas subject to vibration, thermal ﬂ uctuation, expansion or contraction, immersed
applications and when adhering to impervious substrates or tiles. When laying tiles/mosaics in continuous
immersion applications ensure that a minimum 90% of adhesive contact is achieved to the back of the tile/
mosaic cube, not mesh/matting, (paper or other) or the mesh matting glue. Recommended for tiling over
Prohesive approved waterprooﬁ ng membranes only when mixed with undiluted Prohesive PROLASTIC.
All workmanship must be carried out in accordance with AS3958.1-2007.
Apply the mixed adhesive to the prepared substrate using the appropriate notched trowel for the size of the
tile being laid. A minimum of 1mm bed thickness for walls and a minimum of 3mm and a maximum of 12mm
for ﬂ oors must be achieved. Ensure that the tiles are fully supported by the adhesive with no voids. Do not
spread more than 1m2 of PROHESIVE PROSET at a time. Lay tiles into the adhesive before it skins. If
the adhesive skins, re-spread the adhesive. Do not disturb tiles until the adhesive has cured. Discard any
PROHESIVE PROSET that has hardened or stiffened in the mixing bucket. Further addition of water will not
reconstitute a useable mixture.
Allow a minimum of 24 hours for the adhesive to set (or when tile work is ﬁ rm) prior to allowing foot trafﬁ c
or grouting. PROHESIVE PROSET must not come into contact with water at any stage during cure. Do not
tile if temperatures are likely to drop to below 5°C or exceed 35°C. For temperatures below 20°C allow the
adhesive to cure for an extended period of time. If uncertain, check to see if the adhesive has set before
allowing foot trafﬁ c or grouting. For continuous immersion applications allow a minimum of 14 days.
Use the appropriate Polyblend™ grout. Allow joint widths of 1.5mm to 5mm for walls and 3mm to 15mm for
ﬂ oors as per AS3958.1-2007. Thoroughly clean the surface of the tiles to remove all residues prior to the
PROHESIVE PROSET can be removed from the surface of the tiles using a damp cloth while the adhesive
is still wet. Tools and equipment can be cleaned with warm water and detergent prior to the adhesive drying.
2.5 hours at 22°C and 50%RH Setting time: 24 hours at 22°C and 50%RH.
6.6m² per 20kg bag using a 6mm notched trowel and 3.3m² using a 12mm notched trowel.
Unopened bags can be stored for up to 12 months in a cool, dry and weatherproof environment. Bags must
be stored off the ﬂ oor.
PROHESIVE supports best practice in material handling: gloves, mask, safety goggles and protective
clothing should be worn. If the product comes into contact with the skin, wash off with warm soapy water.
Avoid inhaling the dust by wearing a suitable dust mask and provide adequate ventilation. If swallowed drink
plenty of water and seek medical advice. In case of contact with the eyes, rinse with an eye wash or wash
away with plenty of water.
