Strongcoat HB PE




  • High-Build Surface Coating
  • Seamless, hygienic, self-coloured finish
  • Excellent durability in light to medium industrial situations

Strongcoat HB is a two-pack, solvent free, epoxy-based coating, which provides floor surfaces with a seamless, hygienic and cosmetically attractive finish.


Strongcoat HB is applied by brush or roller in two coats and has very good durability towards pedestrian and vehicular traffic. It also has very good resistance towards many of the chemicals commonly found in an industrial environment (consult our Technical Department for further details).

Strongcoat HB can be supplied in a variety of colours (consult our Sales Department for further details).

Slip resistant finishes can be produced for very demanding situations.

Materials Supplied

10kg and 5kg. 


Approximately 4m² per Kg at the specified coating thickness. This coverage figure is based on application to a smooth dense surface. Coverage figures will vary according to the texture, porosity and evenness of the surface on which the Strongcoat HB is being applied.


Store at temperatures between 5°C and 30°C.

Shelf Life

Approximately 24 months if stored in unopened containers and under good conditions.

Application Instructions


The surface must be clean, dry (less than 75% RH measured by hygrometer) and free from dust, laitance, oils, paints or other forms of contamination. Grit blasting can be used to remove laitance and surface contamination (see DCP Guide to Surface Preparation for further details).

For treatment of surfaces containing expansion joints consult our Technical Department.


Strongcoat HB has excellent adhesion to concrete and priming is not normally necessary. If the substrate is particularly porous a priming coat of Strongcoat Primer is recommended.

If the substrate has humidity reading greater than 75%, it is recommended that Strongcoat DPM be used prior to coating with Strongcoat HB.

(Please consult the appropriate data sheets for further details).


Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of the Strongcoat HB Hardener and Strongcoat HB Resin container into a mixing bucket and, using a jiffy-type mixer attached to a slow-running electric drill, mix for approximately two minutes.

Never mix Strongcoat HB by hand as this could lead to areas of uncured material.


Once mixing is complete, transfer the Strongcoat HB to a roller tray and, using a medium-pile simulated sheepskin roller, apply it evenly over the surface.


Strongcoat HB has a working time of approximately 20 minutes at 20°C.

Never leave the mixed Strongcoat HB kit to stand for any length of time prior to application as this will considerably shorten its working time.


Once mixing and application are complete, tools can be cleaned with a suitable solvent.


At 20°C Strongcoat HB should be allowed to cure for 24 hours prior to opening it to pedestrian traffic. At the same temperature, Strongcoat HB should be allowed to cure for approximately seven days prior to opening it to vehicular traffic or exposing it to chemical contamination (consult our Technical Department for details of curing times at other temperatures).


The second coat of Strongcoat HB must be applied no later than 24 hours at 20°C after the first coat has cured. Additionally, the first coat of Strongcoat HB must not be contaminated prior to applying the second coat.


Apply a coat of Strongcoat Primer to the surface and allow it to cure for the specified time (see the Strongcoat Primer Data Sheet for further details). Apply a coat of Strongcoat HB to the primed surface and, whilst this is still wet, completely blind it with an appropriate grade of Aggregate (consult our Technical Department for details of Aggregate grades. Allow the coat of Strongcoat HB to cure for the specified time (see Curing Time) then vacuum off the excess Aggregate. Seal the bound Aggregate with a further coat of Strongcoat HB (consult our Technical Department for further details of coverage rates).

The coverage rate of Strongcoat HB will be considerably reduced when using it to seal aggregates.


Strongcoat HB should not be applied at temperatures less than 10°C.


Consult the appropriate Material Safety Data Sheets prior to using Strongcoat HB.

This data sheet is for general guidance purposes only and may contain information that is inappropriate for certain conditions of use. Accordingly, all recommendations and suggestions are made without guarantee. Further information is available from our Technical Department.
