PROHESIVE PROSET- tile adhesive

By  Last updated: 17th February 2013

PROHESIVE PROSET is a rigid set, high quality cement based adhesive



dPROHESIVE 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

grout drying.


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.
