PROHESIVE PRO MASTIC is a pre-mixed, white, flexible, anti-slump ceramic tile adhesive.

PROHESIVE PRO MASTIC is a pre-mixed, white, fl exible, anti-slump ceramic tile adhesive recommended

for most internal thin bed wall applications. It is suitable for plasterboard, fi brous cement sheeting, cement

render and concrete. PROHESIVE PRO MASTIC is recommended for most internal thin bed wall applications

in bathrooms, toilets and kitchens. It is convenient for the tradesman and ideal for the handyman.


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. Fibrous

cement sheeting and plasterboard must be fi xed in accordance to the manufacturer’s directions and should

be damp sponged to remove all dust etc. Do not use topping compounds on areas to be tiled. Cement render

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.

*When tiling over PROHESIVE approved waterproofi ng membranes prolonged drying will occur. Contact the

CTA Technical department for further details.


All workmanship must be carried out in accordance with AS3958.1-2007. Apply the adhesive to the

prepared substrate using the appropriate notched trowel for the size of the tile being laid. Press tiles into the

adhesive before it skins over. Do not spread more than 1m² of PROHESIVE PRO MASTIC at a time.

At least 80% of the adhesive must be in full contact with substrate and tile. Final bed must not exceed 2mm.

If the adhesive skins, re-spread the adhesive. Do not disturb tiles until the adhesive has cured.


Allow adhesive to cure for a minimum of 24 to 48 hours (or until tile work has fi rmed) before grouting.

PROHESIVE PRO MASTIC must not be washed down for at least 24 hours. PROHESIVE PRO MASTIC

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 30°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 grouting.

Drying time will be extended if used over PROHESIVE approved waterproofi ng membranes and bonding a

dense, low or non-porosity tile.


Use the appropriate Polyblend™ recommended grout. Allow joint widths of 1.5mm to 5mm for walls and

1.5mm to 5mm for walls as per AS3958.1-2007. Thoroughly clean the surface of the tiles to remove all

residue prior to the grout drying.


PROHESIVE PRO MASTIC 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.


Using a 6mm x 6mm notched trowel, 1 litre will cover approximately 1m² on a true fl at surface.


Avoid contact with skin and eyes. Wear overalls, safety shoes, impervious gloves and safety glasses. Use

only in well ventilated areas. No smoking. Avoid contact with foodstuffs, and sources of heat and ignition.

Wash hands after use. Store in a cool place and out of direct sunlight. Store away from oxidising agents.
