COVERAGE
For every 10 mm thickness 20.0 to 25.0 kg (depend on substrate conditions) of dry powder per square meter will be required.
SUBSTRATE PREPARATION
Ensure the concrete substrate is clean and free from oil, grease, sealers, curing compounds, paints, polymer coatings, dust or other foreign (bond breaking) matter. Excess bitumen, adhesive or laitance should be removed by light scrabbling or mechanical captive shot blasting or grinding, followed by vacuuming to remove debris and dust. The substrates should be pre-saturated for preferably 6 hours with water before application.
MIXING
FLOCEM requires approximately 2.5litres of water per 25 kg bag and is best mixed with a forced action, high shear stirrer, or by a heavy duty electric mixing drill at approx. 600 rpm. Add pre measured water to a clean mixing bucket. Gradually add FLOCEM into the water whilst continuously mixing the contents of the bucket.
When the entire contents of the bag have been added to the water, mix for a further two minutes to produce a smooth homogenous consistency. Do NOT mix by hand. Do NOT add excess water. Discard any FLOCEM that has hardened or stiffened in the mixing bucket. Further addition of water will NOT reconstitute a usable mixture.
APPLICATION
The mixed material is poured onto the prepared substrates and spread with a steel trowel and spreader to the required thickness in one operation. Alternatively the use of an electrical trowel will ensure a smooth even finish.
CURING
Start curing after initial setting of FLOCEM, It necessary to cure areas of FLOCEM with humidified method for at least 24 hours.
Protect from direct sunlight or drying winds during cure.
Note: after curing, cutting operation for expansion joint be done.
