Is Enamel Paint Waterproof? 


Is enamel paint waterproof? This is one of the critical questions asked by new painters and crafters. You will find the answer to this question as you read on.    

Enamel paint, whether oil-based or water-based, is waterproof. This type of paint has a bond with uncoated wood surfaces, thereby needing no priming or coating. 

When it comes to metal or stone surfaces, you will have to prime the surface before applying the enamel paint. If not, the paint won’t last for an extended period. 

In general, many enamel paints are waterproof straight from the box. They don’t require sealing or any form of topcoat. 

Acrylic paint is the only type of enamel paint that is not waterproof. It requires priming and topcoat, especially when you want to apply it outdoors.

Indeed, wooden surfaces don’t require priming when applying enamel paints. However, a wooden surface should be primed or sealed with a topcoat if it is an outdoor task. This helps to create a long-lasting bond with some of the underlying materials. The main reason is that the coat protects the paint against the sun’s UV rays to eliminate the risk of discolouration.           

Enamel Paint Fundamentals

You must follow some enamel paint fundamentals if you want resounding results after applying the paint. Here are some of the fundamental rules to follow: 

Part 1 – Choose the right paint and materials for the task

1. Is enamel paint right for your task? – This is the first question you should ask yourself before using enamel paint. You have to decide if enamel paints will be ideal for your outdoor projects. Enamel paint can withstand harsh weather conditions if you have an outdoor painting job. They are also perfect for indoor areas, especially if they are exposed to heavy general wear. Because of their dense and high gloss finish, areas painted with enamel paint can be cleaned with ease, and the paint is also highly resistant to stains and damage. 

  • If you want the surface you will be painting to withstand heavy abuse, enamel paint is perfect.
  • If you want an excellent finish for any material, go for enamel paint. Metal appliances and bathroom fixtures are usually painted with enamel paints.

2. Select the right kind of paint – Enamel paints are traditionally oil-based. The oil content helps the paint mix well and stick to different surfaces for long periods. However, the increased call for non-toxic enamel paints has made water-based enamel paints very popular. 

The water-based alternative is much easier to work with since it dries faster and is easier to clean, while the oil-based version lasts longer, offering a more durable and smoother finish.  

  • Choosing water-based or oil-based enamel paint is a matter of preference. Water-based enamel paint is a good choice for basic projects, while oil-based enamel paint is a perfect choice if you want paint that can stand extreme outdoor conditions.
  • There are different varieties of enamel paints out there. Before purchasing paint, take a critical look at them to know the one that perfectly suits your project. 

3. Choose high-quality brushes – You cannot use just any brush when working with enamel paints. You have to choose a brush with the correct stiffness and filament for the type of enamel paint you want to use. 

For instance, an ox-hair brush or a Chinese brush comes with a softer-bristle brush that can flawlessly spread an oil-based paint. But for water-based paint, you have to choose a brush made of synthetic fibres. This is because the filaments will not soak up the water in the paint and make the surface look foggy.

  • Some brushes have angled bristle edges. This type of brush helps you to have smoother lines when using enamel paints. It helps to give an even finish.
  • Use one type of brush for a particular kind of paint. For example, while using a synthetic brush for oil-based enamel paint is allowed, you must not use the same brush for water-based enamel paint. You have to pick a new brush for the water-based enamel paint.   

Part 2 – The application of enamel paints 

1. Start with priming – Primers help prepare surfaces before the enamel paint is applied. It aids in covering imperfections on surfaces and allows the paint to stick well. A lot of the primers are oil-based. Primers form an excellent seal against the wood and assist the paint to adhere properly when dry. You should apply a coat of primer both on indoor and outdoor materials for a great finish. 

  • There are different primers for different types of surfaces you want to apply the paint. Some of the enamel paints have built-in primers to enhance the adhesion of the paint.
  • A primer must be used when you want to apply enamel paint on woods, trims, cabinets, walls, etc. 

2. Make use of the proper brushstrokes – Since enamel paints are smooth and come with glossy consistency, the painting can make the imperfections on the surface visible. This is why it is advisable to have a second brushstroke after applying the top layer of the paint. 

Make sure the brush bristles are well soaked with paint, and you have to bend the brush when applying the second brushstroke to allow the tip to run well along the painted area. 

  • When you bend the brush when applying the paint, ensure that you move the brush to cover the entire surface part to maintain stroke uniformity in terms of orientation and thickness. 
  • Make sure the brush strokes are fluid and consistent. Surfaces like handmade crafts and furniture may be challenging to paint compared to others because of rough contours. 

3. Use a sprayer – You can also use a sprayer to apply enamel paints. This handheld device helps to give you an even coat since the paint comes out through the nozzle’s holes. Using a sprayer saves you time, especially if you have a large area to cover. 

  • With the sprayer, tough painting tasks such as the coating of outdoor furniture or appliances can efficiently be completed 
  • Thicker enamel paints need to be thinned before being applied using a sprayer.  

Part 3 – Drying and cleaning of enamel paints

  1. Drying time – Water-based enamel paint dries to touch after 1 to 2 hours, while it takes oil-based paint between 8 to 24 hours to dry. This is because of the thickness of the oil-based paint. The drying time may be longer if it is an outdoor project since humidity and temperature can affect drying time. 
  • Ensure that outdoor painting is applied when the weather is warm to prevent excessive humidity. A spike in temperature could impact the drying process.
  • Some brands have quick-drying enamel paints that dry in less than 20 minutes. Look for such paints if you are looking for enamel paints that dry fast.     
  • Touch up worn-out areas gently – Paints should be reapplied to worn-out areas, and this should be applied using a single coat. The fresh coat has to be applied carefully to maintain uniformity. Don’t apply primer when doing touch-ups.
  • Applying a fresh coat helps you avoid a mismatch or variations in thickness. 
  • Cleaning enamel paints when necessary – Since enamel paints allow for smooth finishes, it makes cleaning stress-free. If there is dirt on a painted area, you can mix warm water with liquid detergent and dip a towel into the mixture to remove dirt or debris from the surface. You may need spirit minerals or acetone for oil-based paints to clean the debris.        

Is Enamel Paint Weather Resistant?

Yes, both the water-based and oil-based enamel paints are weather-resistant. This makes enamel paints ideal for outdoor projects. But the rule of thumb is to ensure that the surface is well primed and applied with topcoat before applying the paint. 

Priming and coating the surface help protect the paint from the harmful effect of the UV rays from the sun. If this is not done, the paint may peel or scratch off in no time. The paint also becomes scratch-resistant if a primer is applied before the paint is applied.       

Is Enamel Paint Waterproof? 

We have to provide more details to the question: Is enamel paint waterproof? Yes, enamel paints are waterproof.

If you must use any of these paints on the exterior, you must make sure the surface is primed correctly and coated so that the paint doesn’t peel off.        

How Do You Protect Enamel Paint From Water?

The best way to protect enamel paint from water is to ensure that a coat is applied before painting the surface. Apart from protecting the enamel paint from water, the coating also helps the paint to stand against the elements.
