EPDM Primer Alternative – All You Need To Know

Do you want to use the same EPDM primer on every roofing system you install? Do you want to try something different and more efficient?

Have you ever tried to discover the correct EPDM primer to complete your roofing jobs? If not, it’s time to investigate an EPDM primer alternative that promises to revolutionize the business.

Look no further than our EPDM primer alternative. Using dirty, time-consuming, and sometimes toxic priming products seems devastating, but you get superior adherence and long-lasting effects with better alternative primers.

This post will review why our EPDM primer alternative suits your roofing needs.

EPDM Primer Alternative- Quick Answer

EPDM primer is a must-have for any EPDM roofing or waterproofing job.

Considering the significant types of water-based and solvent-based alternatives, typically solvent-based primers mostly opt.

Besides, various other choices may be more appropriate depending on the unique project needs.


Water-based, acrylic, butyl, and neoprene EPDM primers have different adhesion capabilities but also have environmental concerns, application techniques, and drying durations, making selecting the correct primer crucial for a successful and long-lasting installation.

Water-based is also an addition to our list for a more suitable selection per desired needs.

Are There Any EPDM Primer Alternatives? Detailed Review

EPDM primer or liquid adhesive coating is specifically formulated to prepare and prime the surface of Ethylene Propylene Diene Monomer (EPDM).

If you opt for an EPDM rubber roofing membrane, then you would require an EPDM primer that would be an excellent solution for cleaning the roofing membrane and making it available from enhanced adhesion to allow other coatings to stick well.


With an EPDM coating, the adhesion may stay intact, and the outer coatings may adhere well, causing roofing issues.

The primer works as a layer that also adds protection upon drying. But wait, what if you still need to get the EPDM primer or can’t find one?

For users searching for the best alternatives with more affordability and similar action, we have brought in the best options to opt against the EPDM primer for rubber roofing to ensure you get the desired results without any issues.

The alternatives might vary regarding your task requirements and needs, so choose accordingly, considering the type of project and task requirements. We can divide the EPDM primer alternative based on two categories

  • Water-based EPDM primer alternative
  • Solvent-based EPDM primer alternative

A. Water-Based EPDM Primer Alternative

The water-based alternative offers traditional action, and we want the most popular DM primer alternative.

Its popularity is because it appears eco-friendly and easier to handle and apply.

With the help of a single brush or roller, you can easily use the primer without any issues. The water-based EPDM primer seems ideal for concrete wood or any porous substance.

In addition to the brush and roller application, the water-based rimers are also effectively used in a spray gun that enhances the effectiveness, reduces the overall working time, and ends up clean and finishing looks.

However, remember that using a spray gun might add additional cost if you don’t own one. Users with a spray gun will benefit from using primer and get reduced results quickly.

Acrylic Primers

If you want an EPDM primer alternative for your flat or slightly sloping roof, you can try a water-based EPDM alternative.

With the ease of use, you can also apply it to study surfaces like hardwood and fiberboard.


Before applying the primer, ensure that the surface is clean and that the primer is a single surface, offering better adhesion and wrinkle-free use upon complete drying.

Regarding water specificity, the would-be acrylic EPDM primer is also based on the functionality of its alternative in terms of adhesion.

It is superior to various substrate applications and the ideal wood and concrete substrate solution.

In addition, you can also use it for oral sex straight if applicable, but always keep in mind that using acrylic evidence primer as an alternative for porous substances may require some additional time for caring before you install any EPDM membrane.

B. Solvent-Based EPDM Primer Alternatives

Another alternative to EPDM primer in our list now includes the solvent-based solvent-base choice. There is a substance used other than water that can be anything based on the specificity and required adhesion.

For accurate and precise results, the use of solvent-based primers offers excellent resistance and helps you get a thick, consistent Coating.

They can also provide better adhesion for more advanced surfaces like metal, Timber, cement, concrete, and Rubber.

As the water-based primers take time to dry, the solvent-based ones quickly dry up and create no issues during the application process.

You can also try using this solvent-based alternative for irregular surfaces to avoid making them easily attach while also helping remove the extra gap That seems Odd to appearance.

Use a roller or brush to apply the primer for your desired task.

1. Butyl Primer

Butyl primer is a great alternative solvent-based primer that provides adhesion for butyl base coatings to clean and prepare the surface for better adhesion.

Butyl surfaces would better find the primer more effective and better in bonding.

2. Epoxy Primer

What if you have epoxy base coatings? Which primer to use as an alternative to EPDM primer? No issues.

You can try an solvent-based epoxy primer that replies to the membrane for excellent adhesion and better surface preparation for the desired task.

Remember that solvent-based primers might not be eco-friendly while also causing a pungent odor. In addition, they also require additional safety precautions for primer application.

3. Neoprene Primer

A solvent-based alternative that provides excellent adherence to various surfaces is neoprene EPDM primer. It is often applied with a brush or roller and dries rapidly, allowing for quicker installation.

Neoprene EPDM primer works well on metal, asphalt, and other nonporous surfaces, making it best for detailed surfaces and various adhesion applications.

However, consider that solvent-based primers are less eco-friendly, have a pungent odor, and might require additional safety precautions when installing or applying.

MS Polymers

What if you have a nonporous surface and you’re searching for a good EPDM primer alternative any idea which one to use?

We have brought in the MS Polymers as an excellent alternative for damp and nonporous surfaces with durability, versatility, and liable performance that won’t cause cracks or filling issues concerning other primers.

It seems a great option, offering better sealing and adhesion to joints and providing surface waterproofing.

You can use it for non-continuous damp surfaces because surfaces under continuous water have immiscibility, so the primer coating has a chance of failure.

When applying the product, make sure that the surface is clean. If you need help, you can use an appropriate cleaning agent like Spirit to complete the task professionally.
