Strongcoat Primer can be used where the RH of the substrate is greater than 75%.
Strongcoat Primer is applied by brush, roller or squeegee in one or two coats depending on the texture, porosity and evenness of the surface being primed.
Approximately 4m²/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 Primer is being applied.
Store at temperatures between 5°C and 30°C.
Approximately 24 months if stored in unopened containers and under good conditions.
The surface must be clean, dry and free from dust, laitance, oils, paints or other forms of contamination.
Grit blasting can be used to remove laitance and surface contamination (see the Guide to Surface Preparation for further details).
For treatment of surfaces containing expansion joints consult our Technical Department.
Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of the Strongcoat Primer Hardener container into the Resin container and, using a Jiffy-type mixer attached to a slow-running electric drill, mix for approximately two minutes.
Never mix Strongcoat Primer by hand as this could lead to areas of uncured material.
Once mixing is complete, transfer the Strongcoat Primer to a roller tray and, using a medium-pile simulated sheepskin roller, apply it evenly over the surface.
Strongcoat Primer has a working time of approximately 40 minutes at 20°C.
Never leave the mixed Strongcoat Primer 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 Tool Cleaner or Quickmast Solvent.
At 20°C, Strongcoat Primer should be allowed to cure for 12 hours prior to it being overlaid (consult our Technical Department for details of curing times at other temperatures).
Strongcoat Primer must be overlaid no later than 24 hours after it has cured (see Curing Time). Additionally, it must not be contaminated prior to being overlaid.
Strongcoat Primer should not be applied at temperatures less than 10°C.
