The layer you cannot see
A coating is only as good as its bond to the surface below. Dust, laitance, old loose coatings, oil and moisture all weaken that bond. When a new coating blisters or peels after a summer, the cause is very often something that was left on the surface before application.
What preparation involves
Depending on the substrate and the system, preparation can include removing failed layers, grinding or shot-blasting to open the surface, repairing cracks and spalls, forming fillets at wall-to-floor junctions, and cleaning thoroughly. On roofs, drains, upstands and penetrations are prepared and detailed before the main area.
Moisture and temperature
Many systems have limits on substrate moisture and surface temperature. In Gulf conditions, application windows are planned around the heat of the day, and dew in the early morning. Checking conditions before starting is part of the method, not an optional extra.
Make it visible
We photograph preparation, record inspections and hold the next stage until the substrate is accepted. A client who can see the preparation records is a client who can trust the finished surface.
