Flortex® Freeflow PU

Flortex® Freeflow PU is a medium duty flow applied flooring system with a seamless matt smooth finish. Based upon polyurethane technology it provides a surface with resistance to abrasion, chemical attack and other forms of physical aggression. Flortex Freeflow PU is typically applied at a thickness of 2-3mm. Flortex Freeflow PU Heavy Duty is typically applied between 4-6mm thickness.

Surface Preparation

To be assured of maximum adhesion and best properties from Polycote’s resin products the correct surface preparation is essential. The concrete substrate must be a minimum of 28 days old, and the residual moisture content must be a maximum of 75% RH. The substrate should be sound with a minimum compressive strength of 25 N/mm2 and a minimum pull-off strength of 1.5 N/mm2. The surface must be clean, dry and free of contaminants such as dirt, oil, grease, coatings and surface treatments and contain a functioning damp proof membrane. If in doubt, apply a test area first. Concrete substrates should be mechanically prepared using vacuum enclosed abrasive blast cleaning or diamond grinding equipment to remove laitance and previous surface treatments followed by thorough vacuuming leaving an open textured surface. Weak concrete must be removed and repaired using recommended Polycote products. In order to ensure the finished system remains fully bonded to the sub-floor it is recommended that all terminating edges are rebated to produce a cross-section of 5mm deep by 5mm wide for 2-3mm or 8mm by 8mm for 4-6mm applications, running at 150mm from and parallel with the walls i.e. day joints, movement joints, floor edges, door thresholds etc.

Mixing

Pre-mixing of the Part A coloured liquid component is essential to ensure any pigment settlement is reincorporated. Empty both Part A coloured base and Part B brown hardener component into a rotary drum mixer and mix for a minimum of 1 minute then slowly add the aggregate component in stages, mix for a minimum of 2 minutes until a lump free consistency is obtained. Never mix by hand. Do not split packs. It is essential that the mixing station and the supply of materials are positioned such that a continuous supply of mixed material can be maintained to minimise breaks in the application process.

Application

Apply the mixed Flortex Freeflow PU by trowel or pin rake to the required thickness. Within ten minutes roll the Flortex Freeflow PU with a spike roller in order to de-aerate the material. When the material is sufficiently cured existing joints in the sub floor must be carried through into the Flortex Freeflow PU screed. The ambient temperature of the works area should be a minimum of 15°C during the application and curing period, if not adhered to this can affect the performance of the system. Materials and substrate temperature must remain above 15°C all times.
