• Britannia Durashield FD Primer will be dry under normal conditions in 2-4 hrs depending on humidity and temperature and can be overcoated when dry.

Preparation

• Ensure the substrate is free from old plant and debris.

Cleaning of Substrate:

• Clean the surface with a powerwash of up to 2,000 psi, depending on the substrate.

• Once the substrate is clean and dry you can then begin the application.
