Bin Primer vs. Kilz for Cat Urine

It can be not very pleasant to have to deal with cat urine on your furniture and carpets. What is even more challenging to deal with is getting the stain and smell off. Bin Primer and Kilz are excellent choices for removing stains, but which is the better option?

Bin Primer is a shellac-based primer that is not just used to remove and seal stains but will also permanently get rid of the smell of the cat urine. Bin Primer also does a great job of covering stains on interior surfaces. It can also eliminate other stains like markers, lipsticks, sap streaks, asphalt, etc.

Kilz primer is a heavy-duty odor-blocking primer that is latex or oil-based paint. It has an excellent resistance to mildew which helps in the sealing of stains and blocking of smells. Not only does it get rid of the smell of cat urine but also other smells like nicotine, grease, oil, black soot, tannin, pencil, etc.

Bin Primer is more expensive, has a faster drying time, and can give high coverage. On the other hand, Kilz Primer is the more affordable option and does not give as much coverage as its rival. It also does not dry as fast as Bin Primer does.

Key Differences Between Bin Primer and Kilz Primer


When it comes to providing high coverage, Bin Primer has the upper hand. It is a very thick product, and this increases its durability. Due to its consistency in thickness, you may not necessarily need to add more than one coat, increasing its coverage. One coat should be enough to get rid of the smell of cat urine.

Kilz Primer is much thinner, making it easy to spread and stir (an advantage for DIY users) but reduces its coverage level. It also allows for bleed-through, so you need to apply more than one coat, giving better coverage. Most users do not like to use Kilz Primer because of its low coverage ability.


You do not necessarily need to sand your surface before applying Bin Primer, except you want an extremely tight bond. It contains a high adhesion shellac formula which enables your paint to last for a long time. The higher the durability, the better the chances of your stain remover not scraping off.

Before applying Kilz Primer to your surface, you must sand the surface first. But because it is an oil-based paint, it is easier to sand. It is good at resisting mildew, and the adhesion does a great job in blocking the urine odor and sealing the stain.


Bin Primer is the more expensive option, so Kilz Primer is the better option for you if you are on a budget. Kilz Primer’s price ranges from $8 to $42 per gallon, while Bin Primer’s prices are as high as $10 per quartz. One good thing is that they give you your money’s worth.
