 ROCATEX C2FT S1 Rapid Fibre Flex White is a single part, flexible, rapid setting wall and floor tile adhesive 

for fixing natural stone and tiles including ceramics, porcelain and mosaics to a variety of substrates. Suitable 

for interior and exterior use.

 This high performance, polymer modified, fibre enhanced S1 flexible adhesive can be used up to 20mm.

 Capable of fixing almost every type of tile to almost every type of substrate, the non-slip/non-slump ‘T’ rating 

(≤0.5mm slip resistance) makes it ideal for large format tiles and natural stone.

 PREPARATION

 All installations should be carried out in accordance with BS 5385. All surfaces must be clean, firm, dry, free 

from all loose matter including dust, dirt, oil, grease, laitance and any other contaminants that may affect 

adhesion. All substrates should be prepared to provide a rigid and secure base without deflection and suitable 

to support the intended weight. New timber should be given time to find equilibrium with its surroundings.

 The following information provides further details for preparing various common substrates. Unless stated 

otherwise, any reference to the term “diluted” means 1 part primer mixed with 1 part clean water. N.B. All 

primer applications should be fully dry before next works commence.

 Anhydrite Screeds - The substrate must not leach moisture. Anhydrite screeds must not have a moisture 

content greater than 0.5% or 75% relative humidity (RH). This can easily be tested by taking moisture readings 

across the whole surface. It is essential that surface laitance is removed in accordance with the screed 

manufacturer’s recommendations, followed by vacuum cleaning to remove any loose material, then apply 1 

diluted coat of ROCATEX Acrylic Primer followed by a minimum of 2 neat coats or 2 diluted coats of ROCATEX 

Ultimate Grip Primer.

 Concrete Screeds - Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX 

Ultimate Grip Primer. Substrate curing before tiling can commence is approximately 6 weeks.

 Power Floated Concrete - The cured surface should be mechanically abraded to remove any curing agents 

and open up the surface, followed by vacuum cleaning to remove any loose material, then apply 2 diluted 

coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer. Substrate curing before 

tiling can commence is approximately 6 weeks.

 Sand & Cement Screeds - Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of 

ROCATEX Ultimate Grip Primer. Substrate curing before tiling can commence is approximately 3 weeks.
