In-Depth Differences Between Kilz Original And Kilz 2

You have gathered some basic ideas on how these two primers are different than one another. But for making the right decision, you have to have more details in hand. In this part, I will give you a comprehensive comparison between the two primers.

So, stick with me here.

  • Type

Kilz original is a white color oil-based primer for interior use only.

With its stain-blocking formula allowing it to block most heavy interior stains, you can protect your surfaces from smoke and water.

Apart from that, it offers protection on various other surfaces, including tannin, ink, pencil, felt marker, grease, seal pet, food, and smoke odors.

On the other hand, Kilz 2 all-purpose is a fast-drying primer, sealer, and stain blocker. This multi-purpose primer offers excellent adhesion on various exterior and interior surfaces.

Besides, with this multi-surface primer, you will get mildew resistance, sealing features, and very little odor.

  • Features

Although Kilz Original and Kilz 2 are both surface primers, you will find some differences between their features. Kilz Original helps block severe water and smoke stains on various interior surfaces.

Besides, it promotes excellent adhesion to any type of paint for interior walls. You can quickly seal your interior walls or ceiling against pet and smoke odors.

But you have to prepare the surface well before applying this primer.

On the contrary, Kilz 2 features mildew resistant finish on both interior and exterior surfaces. It allows you to block light to medium stains on the wall and ceiling. Being a multi-purpose primer and sealer, it offers sealing new drywall.

  • Benefits

Both Kilz Original and Kilz 2 offer a lot of benefits. However, one of them exceeds the other. Let’s find out the key benefits these two primers offer.

Kilz original blocks heavy interior stains. It can seal smoke, pet, and food odors on your interior surfaces. Most importantly, this low VOC primer can hide previous paints.

As a result, you can easily apply new paints to interior walls.

In contrast, you can use Kilz 2 all-purpose primer under or over water-based and oil-based paint. So there’s no restriction there.

Offering an enhanced hiding feature, it allows you to hide previous colors and makes it an ideal solution for changing colors. Moreover, you will need less number of paint coats.

  • Usage
Kilz 2 Primer

Kilz has developed both products to offer a particular usage.

That is, priming the surfaces before top coating. But the difference lies in where you can use them and why.

Use Kilz Original on wood, plaster, wallpaper, drywalls, paneling, painted metal, masonry, glossy surfaces, and brick.

But unfortunately, you cannot use it on mold and mildew-prone surfaces, exterior walls, and flooring.

On the contrary, you can use Kilz 2 on interior and exterior surfaces, including woodwork, brick, paneling, drywall, painted metal, glossy surface, and masonry. The only place you cannot use it is the flooring.

  • Performance

Performance can create a huge difference between two similar products. But for Kilz Original and Kilz 2, you won’t find many differences in their performance.

Both primers sealers and stain blockers can cover up to 300 square feet per gallon for porous surfaces and 400 square feet for non-porous surfaces. Besides, they take 30 minutes to become touch dry, and you can recoat in just 1 hour.

  • Available Sizes

Available container size can be a factor in choosing a specific product. Customers would always want to purchase as close to their requirements as possible.

Kilz Original is available in 1-gallon and 5-gallon containers. Similarly, Kilz 2 is also available in 1-gallon and 5-gallon containers. So, no differences here either.

  • Clean Up

Easy cleaning of the primer from tools and equipment will help you finish your project fast. Plus, you do not have to put so much effort into it.

You can clean Kilz Original from its tools and equipment with mineral spirits.

On the contrary, Kilz 2 cleans with just regular water. You do not require any soap or spirit to clean it from the tools and equipment. So, as we can see, Kilz 2 is actually easy to clean than the Kilz original.

  • Dry Time

A significant difference one can observe between both primers is their drying time. When a Primer dries quickly, it means it is thicker and will be ready for the second coat in less time if there is a need for a second coat.

The Kilz 2 Primer is just like that. It dries only in 20 minutes and gives you a quick chance for the second coat.

Compared to that, the Kilz Original takes more time to dry, up to 1 hour. Hence, you will have to wait for more for the second coat of this Primer.

  • Areas Usage

Whether you use Kilz original for small or large surfaces is no problem. It can be applied to both.

However, the application of Killz 2 is only for smaller surfaces. It increases adhesion and cannot be used excessively over larger surfaces.

  • Toxicity Level

A Primer or paint should be non-toxic to keep you and your hands safe. In that regard, the Kilz Original is a little toxic primer you should know before buying it.

Conversely, the Kilz 2 is a non-toxic primer and suits best in case you want safety while painting those wooden items.

  • Usage On Woods

As I stated, one can apply the Kilz Original on larger wooden blocks such as wood floors. It will cover those areas and provide you with the best protection.

Contradictorily, you can use the Kilz 2 only for smaller wooden items such as trims, doors, and other cabinets.

  • Price

Comparing both the prices and your budget, they do not cost much. Yet, when you find this product on Lowes, the Kilz Original costs you much less than Kilz 2.

That’s because both Primer has different properties, but both are high-quality Primers offered by Kilz that ensure greater protection against all types of damages.

So you can decide accordingly which Primer will suit you best for your next project.
