APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION

Contact surfaces must be sound, clean and provide a

good mechanical key. Remove any loose material, lait-

ance, plaster, paint and oily deposits.

SUBSTRATE QUALITY / PRE-TREATMENT

Prepare a priming scrub coat of Parex Bond Plus Mor-

tar. Prime the prepared substrate and the underside

of the paving units with the priming scrub coat using a

stiff bristle brush. Apply the Parex Fine Bedding Con-

crete (FBC) before the priming coat has dried (i.e.

'wet-on-wet').

MIXING

Mixing of bagged Parex Fine Bedding Concrete (FBC)

requires a forced action mixer such as a Creteangle.

Pour the recommended amount of clean water into a

suitable mixing vessel. Gradually add the powder and

mix thoroughly until a homogeneous product is

achieved. Once mixed, apply within the pot life. Addi-

tional water should not be added to 'revive' the

product past its pot life.

APPLICATION

Apply the mixed Parex Fine Bedding Concrete (FBC) to

the primed substrate before the priming coat has

dried (i.e. 'wet-on-wet'). Compact the Parex Fine Bed-

ding Concrete (FBC) to ensure good contact with the

underlying primed surface. It is advisable to dip setts /

cubes in water to clean them prior to priming. Prime

the back / underside of the paving units being used

and place the units onto the wet Parex Fine Bedding

Concrete (FBC) and adjust the levels as required. Al-

ways ensure that the Parex Fine Bedding Concrete

(FBC) layer is fully compacted.

Application thickness of the Parex Fine Bedding Con-

crete (FBC) should be in the range of 30 mm to 75 mm

(40 mm is typical for most applications). In situations

where thick layers are required to be built up, the sur-

face of the lower layer should be left with a wood float

finish and should be scored. Subsequent Parex Bond

Plus Mortar and Parex Fine Bedding Concrete (FBC)

layers may be applied as soon as the initial layer is

firm enough not to distort under the new work.

CURING TREATMENT

In temperate ambient conditions, no special curing is

required. In severe drying conditions of high temper-

atures and high wind, the paved surface should be

sprayed with water to assist with temperature control

of the paving surface and provide water for additional

curing of the Parex Fine Bedding Concrete (FBC).

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water

immediately after use. Hardened / cured material can

only be mechanically removed.
