The mixing process is such that only specially manufactured mechanical mixers will achieve the correct consistency of mixed material. Conventional ‘cement’ type mixers are not suitable for this purpose. Critical aspects of the mixing process are the time taken to satisfactorily mix an individual batch and the time taken to place the material in final position following initial addition of the binder.
The mixed material is normally transported from mixer to final location by dumper or barrow and placed on the prepared base by shovel, rake and/or loot. Speed of operation is of the essence due to the fact that the material will be gradually curing and will become difficult to work in a period, which will vary depending on the ambient weather conditions, but may be as little as fifteen minutes after mixing.
The finished level is achieved by trowelling off the polymeric mixture and compacting by combination of hand trowelling and/ or rolling with a smooth wheeled roller. Keep your trowel clean and lubricated with a release agent to achieve a uniformly smooth finish. On completion the finished surface should be inspected to ensure there are no roller or trowel marks.
Allow the base layer to cure (or at least partly cure) before the top layer is applied. The top layer must be fully cured before the surface is commissioned, this could take at least 24 hours subject to weather conditions.
It is important to ensure that construction joints or overnight joints are kept to a minimum within each area of surfacing. Construction joints may be required due to the overall dimensions of the area, weather problems etc. All joints should be constructed in a straight or curved line which must be regular in appearance.
Compaction must be ensured at any joints and around equipment legs, edging kerbs, etc. To aid adhesion it is advisable to prime edgings with a diluted binder solution prior to placing the surfacing.
it is possible to inlay patterns of different shapes and colours within the wet-pour surface. This may increase the ‘play value’ of the surface and improve the aesthetics of a particular installation. These patterns of contrasting colours may be achieved by using shaped moulds of the same thickness as the top layer, manufactured from plywood, polystyrene or similar. the basic colour of the top layer is installed with the mould in place and when this layer has cured, the mould is removed and the contrasting colour is trowelled into the shape left by the mould. On completion, the installer must ensure that the joint between colours is properly compacted with no trip edges or open areas at the interface.
Clean the mixer and tools immediately upon finishing the installation. Scrape off the thick of the residue and finish with release agent on a cloth. Provided that you clean most of the residue from the buckets, you should be able to peel off the thin skin left inside the buckets once it has cured.
The binder is “messy” when wet, keep it off your clothes and skin as far as possible – further information can be found on the product label. The binder cures to form an inert urea, so there are no special disposal requirements after full cure.
