Application methods include spray: either air spray or airless spray. Brush which is recommended for stripe coating and small areas. Care must be taken to achieve the specified dry film thickness. Roller which may be used for small areas. Not recommended for first primer coat. Care must be taken to achieve the specified dry film thickness.

Drying and curing times are determined under controlled temperatures and relative humidity below 85%.

The coating of Vinyguard Silvergrey 88 will be resistant to various immersion temperatures depending on the specific chemical and whether immersion is constant or intermittent.

Vinyguard Silvergrey 88 is available in 5 and 20 litre tins and has a minimum shelf life of 48 months within a cool, dry and well ventilated space that is away from any sources of heat and ignition.


Vinyguard Silvergrey 88 is a fast air drying vinyl matt coating which can be used as a primer or intermediate coat in atmospheric and immersed environments, also as a tie coat for antifouling systems. It can be applied direct to steel and wooden hulls by Airless spray, Conventional spray or roller.

Vinyguard Silvergrey 88 is recommended for topside, deck and superstructure on steel and wood vessels. It can be used as a tie coat over sound unknown existing coatings to upgrade the system to a Jotun marine specification.

It is resistant to continuous temperatures of up to 60°C and 40°C in immersed sea water.

To secure lasting adhesion to the subsequent product all surfaces should be clean, dry and free from any contamination.

For carbon steel it is recommended that the surface is blast cleaned which makes it free of all visible oil, grease, dirt, dust, rust or any existing coatings.

For coated surfaces it is recommended that the surface is clean, dry and doesn’t have any damaged coatings.
