Preparation of the surface
This is the most important part of any floor installation, a badly prepared floor surface
will adversely affect the physical and electrical properties of any coating applied to it.
Concrete
Bare concrete is not normally an adequate surface for the application of floor paints,
especially Static-Dissipative floor paints where the electrical properties can be
affected. Ensure that the concrete is DRY (less than 5.5 on Protimeter Screed Scale or
less than 15% Moisture Content).
All concrete floors should be sealed with a two pack, Solvent Free/Water Based, Epoxy
Sealer/Primer (Edson Electronics Ltd can offer such a primer if required) to stabilise the
concrete and to insulate against excessive conductivity, a major problem to static
sensitive areas.
Before sealing the concrete it is advisable to prepare the surface using Mechanical
Preparation or an STR machine in order to give an open, sandpaper like surface. All oil,
grease and chemicals should be removed by washing with an alkaline detergent, and the
floor allowed to dry thoroughly before sealing.
Apply the sealer/primer as the instructions dictate, and allow to hard dry. Do not
exceed the recommended re-coat time.
