Kilz products, such as the Kilz Original, are easy to sand and provide a smooth finish to oil-based paints. 

Main Differences Between Zinsser and Kilz Primers

So, what are the perks or disadvantages of choosing a Zinsser or Kilz brand? Knowing these differences will save you from unnecessary expenses, stress, and disappointment. 

Kilz primers tend to work better on floors than on walls. They also have a slower drying time compared to Zinsser primers. But Zinsser primers have better coverage because of their thick consistency.

Let’s explore these differences in more detail:

Is Zinsser or Kilz Better for Eliminating Pet Urine Odor?

It’s embarrassing when your new or old apartment reeks of pet urine. The stench is unmistakable, and you’ll require a solid primer to mask the smell before you invite guests over. 

This review focuses on the Kilz Restoration Interior Primer and the Zinsser Bin Primer. 

The Kilz Restoration Interior Primer is a latex-based primer designed to seal out different odors, including smoke and urine. It acts fast and can block odors in less than one hour. Zinsser Bin Primer is a low-odor, latex-based primer that also traps odors on walls, sub-floors, and cabinets.

The Kilz Restoration Interior Primer forms a seal on porous surfaces and traps stains. It’s suitable for removing pet urine stains on floors, including sub-floors. 

The Zinsser Bin primer will turn white when applied to surfaces. But it gradually becomes clear over time. When this happens, it means the primer is dry and has wholly sealed off any strong smells beneath. 

Which Primer Dries Faster?

How fast does the primer dry off? It takes an average of one to four hours for most primers’ first coat to dry off. However, an ideal primer should be dry to the touch within 30 minutes of applying it. 

Once again, we’ll compare the drying rate of the Zinsser Bin Primer against the Kilz Restoration Interior Primer. 

The Zinsser Bin Primer becomes dry to the touch within 15 minutes and is ready for another coat after 45 minutes. Most times, you only need to apply one coat to seal in odors. Kilz primer is slower, taking 30 minutes to dry to the touch. Its curing time is 1 to 2 weeks.

Final Thoughts: Zinsser primers are the best solution for those who want a quick-acting primer. It dries and cures much faster than Kilz Primers. 

Just note that the Zinsser Bin primer has a strong odor since it contains denatured alcohol. Ensure the room is well-ventilated, and wear a face mask when using it.

Cats will pee on different surfaces to mark their territory, and the urine will often leave a dark stain on walls or floors. So you need a heavy-duty primer that can cover these stains after only one or two coats. 

Zinsser Bin Primer has a thick consistency and can block most stains in one coat. Despite the primer’s thickness, it is easy to apply on surfaces via spray cans. Kilz Restoration Interior Primer has a much lower coverage, requiring 3 to 4 coats to hide cat urine stains.

In addition to this, the Kilz primer takes more time to dry. So, you’ll end up spending more time working with it. 

Final Thoughts: It is more stressful and messy applying Kilz Restoration Interior Primer. You might even end up with a sloppy paint job. The Zinsser Bin Primer primer wins this round.

Conclusion

Zinsser primers are more expensive than Kilz primers. Nevertheless, you will get more value for your money with Zinsser primer brands: A single coat of this brand’s primer is enough to block urine stench and stains on any surface. Zinsser primers also dry faster than Kilz primers.

If you want something cheaper and don’t mind a little extra labor, though, then Kilz is probably for you. However, the need to apply several more coats may undo any savings.
