    Strongcoat Fast Cure is a two pack, solvent free, very hard wearing and fast curing epoxy floor paint for use in heavy duty areas where a hard wearing and chemical resistant surface is required.


    A smooth gloss finish in a range of attractive colours.

    N.B. colour range may be limited for fast curing products. For further information, please contact our Sales Office.

    Pack Sizes

    2.5 and 5 kg packs each comprising a tin of resin and a tin of fast curing hardener.

    Suitable Surfaces

    Concrete, metal, polymer modified cementitious screeds.

    Typical Installations

    • Processing and manufacturing plants.
    • Frequent fork lift truck traffic areas
    • Factories and warehousing
    • Food preparation, food storage areas and breweries.
    • Commercial garages, vehicle repair and maintenance depots, aircraft hangers
    • Chemical plant storage areas.
    • Car Parks


    • Even on rough and uneven floors, it will cure to give a smooth, easy to clean surface.
    • Excellent chemical resistance.
    • Hygienic, seamless floor finish.
    • Low odour
    • Solvent free
    • Will not support bacterial growth
    • Fast turnaround (fast curing)

    Can be made anti-slip with the addition of Virtus Anti -Slip Aggregate scattered into the first coat of wet resin.


    Indoor (some colour change would occur if used outdoors). Ideal for live sites and areas which require faster turnaround and where time limitations may necessitate a faster initial cure time (working between shifts or close down periods).


    20 square metres per 5kg. Two coats are usually required


    Approx 0.5 mm (from 2 coats). Can be built up to a maximum of 1 mm thickness from the application of multiple coats.

    Cure Schedule

    • Pot Life: 10-15 minutes at 20°C
    • Hard Cure (Light Traffic): 11 hours at 20°C
    • Full Cure: 5 days


    Hot water jet washing, detergents and mechanical scrubber dryers.


    A primer is not normally required. However, on weak or porous concrete it is advisable to prime with Flowprime SF. For floors suffering from oil contamination, where oil has penetrated the slab, it is available to prime with Flowprime OCS. For floors where there is no damp proof membrane in the construction of the floor or if the concrete is new and has not had time to dry out thoroughly, it is advisable to use Flowprime DPM.

    Surface Preparation

    Surfaces to be treated must be clean, sound, free from oil or other contaminants, flaky paints, laitance and dust. Smooth and dense surfaces must be mechanically abraded to provide a key. Please read our Surface Preparation Datasheet.

    Application Conditions:

    Strongcoat™ Fast Cure is a relatively viscous coating. Do not apply outside of the range 10 °C to 25 °C. Localised heating or cooling equipment may be required outside this range to achieve ideal temperature conditions. To reduce the risk of “blooming” caused by condensation, the climate above the uncured floor should be maintained at least 3°C above the dew point for at least 48 hours after application.

    Surface Preparation:

    Concrete substrates must be a minimum of 28 days old, dry, clean and free of surface laitance and contaminants such as dirt, oil, grease, poorly bonded coatings and surface treatments. Inadequate preparation will lead to loss of adhesion and failure. In coatings, there is a tendency for the finish to mirror imperfections in the substrate. Grinding, or light vacuum-contained shot- blasting is therefore preferred over planing for these systems. Concrete must include a functional damp-proof membrane.


    Strongcoat™ Fast Cure does not normally require a primer on dry substrates. When treating extremely porous or damp concrete, prime as follows: Substrate relative humidity <75%: Flowprime SF (Weak or porous) Substrate relative humidity >75%: Flowprime DPM (’green’ concrete).


    Best results are obtained in warm conditions (minimum 15 ºC ). Apply with a medium pile simulated sheepskin roller working well into the surface taking care not to exceed the coverage rate. Edges and difficult to reach areas may be applied thinly by brush. An anti-slip finish may be achieved by fully sprinkling the first coat with kiln dried silica sand at 3 - 4 kg/m². Allow the first coat to fully cure (24 hours at 15 ºC or longer in colder temperatures) then remove all excess sand with a stiff broom and vacuum and apply a second coat to encapsulate the grains. Coverage rate will depend on surface profile but will be significantly greater than for the first coat. As a guide:

    Note: These coverage figures are approximate as silica sand grading can vary widely as can site conditions. If in doubt, order extra material to account for wastage or install a test area prior to starting works. The pendulum test values given above are derived from testing in a controlled laboratory environment and are given for guidance only. Results derived from testing field-applied samples may vary dependent upon site conditions and application technique. Slip resistance can reduce over time due to poor maintenance, general wear or surface contaminants. Good housekeeping practices should be observed.

    Fast Cure Limitations:

    Time limitations may necessitate a faster initial cure time (working between shifts or close down periods) in which instances the use of a Fast Cure hardener can be employed. On average, this has the effect of reducing the hard cure time by 1/3 but also reducing the usable life by 1/2, for example:

    Strongcoat Standard
    Hard cure time at 20°C - 16 hrs
    Usable life at 20°C - 30-40 mins

    Strongcoat Fast Cure
    Hard cure time at 20°C - 11 hrs
    Usable life at 20°C - 20 mins

    Physical and chemical resistant properties are little affected by this substitution. It should be noted that despite the accelerating effect of this hardener over hard cure time, the resistance time of the product to chemical contact will still only be achieved after normal 5 day cure period. The hardener adopted for the fast cure epoxy system has been designed to reduce hard cure time at “normal” application temperatures (15-20°C). This product should not be specified as a means to providing an epoxy system capable of curing in temperatures below 10°C as this will lead to extended cure times with the possibility of carbonate salt formation if the ambient humidity is high.
