Best Uses

Sigma AquaCover 500 coating provides durability for surfaces in readiness for overcoating, with topcoats from the Sigma Topcoats range. AquaCover 500 can be overcoated with most dispersion and alkyd paints to create a durable finish but we recommend that surfaces are primed with AquaCover 200.


Sigma AquaCover 500 can be applied using an airless spray, long haired brush or roller a with rounder edges. It has an ultra fast drying time, touch dry in 4 hours (in temperatures of 20 degrees celsius) and an overcoat can be applied after 16 hours. Sigma AquaCover 500 has a theoretical coverage rate of 10.4m sq. per litre and is available in a white finish suitable for use on metal and concrete floors.

Surface and Environment

Sigma AquaCover 500 is designed for use in industrial or coastal exposures where weathering can be a massive factor in causing damage to surfaces. Sigma AquaCover 500 is ideal for use on structural steel and galvanised steel.
