How to Paint an Outdoor Oil Tank?

Simple few steps of the painting process don’t require any strenuous tasks. You can DIY paint it entirely without any second thought, even if you haven’t painted it ever.

Here are the steps to follow for better results.

Inspection

The very first thing you need to do is to check and measure the current condition of your outdoor oil tank. It needs to be done gauging the level of work that would be required. If the tank has rust on it and previous paint has been damaged, you have to scrub these off.

But if the damage is at an extended level and the tank seems too damaged, you better think of getting a new one.

Cleansing

A proper cleaning would give you a basement for the painting, so you must be very careful about it.

Start with a degreaser, not a regular soap. Regular soap might work on visible dust and derbies but might leave unseen dirt. This can prevent paint from properly adhering to the tank.

To peel off the rust and hard dust, use steel wool. It works better to scrub even the hard surface without much effort.

Lastly, use a wet rag to rinse the oil tank after getting done with the cleaning job. Now leave it for a few hours to dry properly.

Applying Primer

As paint usually doesn’t get along with wood and metal, it’s recommended to go for a Primer. And the best available one for the metal surface is the etching primer. Etching primer ensures maximum adhesion of the paint to the different metal surfaces.

When the tank is completely dried out, you can start applying the primer. Before that, try to roll on a small cloth underneath the tank to avoid spoiling the ground. Try to use a polyester brush as a nylon brush might leave lines and spots in the finishing touch.

Paint

Interestingly, many people paint their tanks with regular paint without thinking for a second time that it’s metal. Ordinary paint is a water-based acrylic that doesn’t hold well on the metal surface. Regardless of the warning, if you use it, it’ll only create a bigger mess instead.

Go for an oil-based enamel paint, which is perfectly suitable for metal painting. With the brush or roller, paint the tank delicately. Usually, one coat is enough to protect the tank well, but if you insist, you can go for a second coat.

Besides, the color of the paint should be well reflective and light, preferably white or black. Don’t go for a deeper shade that absorbs heat from the sun.  

Dry

Dry the paint properly for at least a few hours or a day before your kids and pets jump over to touch it.
