Is it possible to paint a galvanised storage container
We understand that, especially in a domestic setting, a shiny galvanised finish may not suit
everyone. But, galvanised steel is very hard wearing and offers excellent corrosion protection
ensuring a long life, lasting decades.
We do not offer a painting service or colour options for our containers but it is possible to
paint your container when it’s assembled or before assembly.
What is Galvanising
Galvanising is the process of protecting the steel by applying a zinc coating. This zinc coating
protects the containers in all weathers from the effects of rust and corrosion. The only
reason to paint a galvanised container is to change the colour as it is not necessary to apply
paint to provide any additional corrosion protection in a normal environment.
The galvanised finish of our containers is smooth and shiny when new. This makes it difficult for standard paint to stick and adhere to the surface. The manufacturing process leaves a slight oily residue that will allow any paint to peel off after a few months. But with the correct surface preparation it is possible to successfully paint your container. After the finish has weathered for 12 months the options are a bit easier. For a new container there are 2 options that have proved to have worked on new galvanised finishes. There are also different paint and coating manufactures bringing new products to the market for both professional and DIY application.
What Are My Options?
Option 1. Use a ‘Direct to galvanised paint’. Follow the manufactures instructions as this will
differ between brands. This usually includes cleaning all surfaces with soap or de-greasing
agent. A good traffic film remover, known as TFR, applied with a pressure washer is
effective. Allow to dry and apply with brush or roller. There are also coloured Zinc spray
paints available which will give a good DIY finish.
Option 2. Treat the galvanised surface with ‘Mordant Solution’ also known as ‘T Wash’. This
acidic solution is a pre-treatment for clean zinc coated galvanised finishes. This turns the
galvanised silver colour to a black finish. The acid etches the top layer neutralising the salts
created by the zinc. Then apply a primer to the steel followed by a top coat in the colour of
