Does Elastomeric Paint Need A Primer?

Ready to get down to painting with Elastomeric? Before doing so, you may wonder whether you need to prime it. Elastomeric paint is quite different from the usual paint you buy in the market, so does it mean you'll need to use a primer? Well, we're here to help you answer this!

Elastomeric paint is just like any other paint when it comes to priming: it needs it. Elastomeric doesn't penetrate the surface you put it on; it only covers the outside.

That's why priming is crucial if you want the paint to adhere well and last long. The primer will also help cover imperfections to protect against moisture.

Do you still need more reasons to primer your surface before applying elastomeric paint to convince you further? We've got more information on the deck for you. Furthermore, if you finally decide to prime, we've included a guide. With that said, let's dive right in!

Primer On Elastomeric Paint

The most important reason you should prime for elastomeric paint is that although it's thick, it doesn't soak through your surface and can't easily stick to it.

That's where the importance of paint primers comes in; because it provides a rough and porous texture for your surface, your elastomeric can adhere well.

Using them is the best way to assure you that your elastomeric paint doesn't peel because of the lack of adhesion.

In addition, primers help with helping your elastomeric paint last long because of their waterproofing ability. They penetrate under the imperfections on your surface, which moisture can get in.

Elastomeric paint doesn't seep through spots like this, and priming can cover up for this instead.

Never start painting if your primer still isn't dry enough. The drying time of primers highly depends on what type of it you've used, but generally, primers must sit for at least 24 hours before you can start painting.

To be more specific, latex primer takes 30 to 60 minutes to dry and should be primed within 21 days before it loses effectiveness.

Meanwhile, oil-based primers dry after 8 to 24 hours and can only sit for up to 14 days without painting.

Lastly, water-based primers dry within 30 to 60 minutes to dry and are best painted within 72 hours after application but can last for one to three days before losing adhesion.

Before painting elastomeric, ensure that the surface you'll put it on is clean. You can do this through power washing between 2000 and 2500 psi to prevent damage.

Note that you shouldn't add bleach or cleaner to the water for power washing.

But, if you don't have a power washer, you can use a stiff broom or wire brush instead and wash the surface with water after. Then, leave the surface for air drying.

After cleaning the area you'll paint, you can then proceed with applying your elastomeric by doing these:

  1. Mix the product with a stir stick. The elastomeric paint may have settled under the can, so you must mix it well before applying. Avoid creating bubbles while doing so.
  2. Wet your brush or roller, then remove the excess water by squeezing it out.
  3. Apply the paint with your damp brush or roller. You can try painting in a "V" shape to cover all the areas.
  4. Leave the paint to dry and apply a second coat. Generally, the thickness of the product during application should be in 20 dry mils, which needs two coats to achieve. Ensuring this is achieved is essential to provide you with the best weather and waterproofing. However, you may check for the recommendations of your elastomeric manufacturer for this too.

How Long Does Elastomeric Paint Last?

Elastomeric paint can last up to ten years, making them an excellent choice for exterior walls or surfaces. Unlike ordinary paints, it's more durable, so it may even last longer than its expected lifespan.

Aside from this, it provides a watertight protective coating on your surface, making it last long without damage.

To Finish

You should prime surfaces you'd apply elastomeric paint to ensure the product adheres well. Elastomeric only covers the outside of the surface and doesn't soak in. It may peel off without any primer immediately after application or drying.

The primer acts as a rough adhesive for the Electrolux paint while also blocking moisture from getting into the surface you'd paint, so there shouldn't be any reason not to choose to apply it.

It shouldn't be a complex task if you're confused about how to prime after finally deciding to apply it. You only have to choose the primer most suitable for you, prep your surface, then put your elastomeric paint on the surface with a brush or roller.
