Visual Inspection

Check the consistency and texture of the Kilz Primer. A good primer is smooth and even. If it feels chunky or lumpy, it may be bad.

Observe any color changes in the primer. Fresh primer has a uniform color. If you see separation or settling, it could indicate spoilage.

Mix it well before using. If it does not return to a smooth state, it’s not good. Always ensure the lid is tightly closed after use.

Smell Test

The smell test is an easy way to check Kilz Primer. Fresh Kilz has a clean, mild odor. It should not be overpowering or sharp. If the smell is foul or rancid, it’s likely bad.

Identifying off odors can save you time and effort. A sour or stale scent means the primer has gone bad. Always trust your nose when checking paint products.

What a fresh can smells like is simple. It should have a slight chemical scent but not be unpleasant. A good can will not make you feel sick or dizzy.

Stir Test

To perform a stir test, start with a clean stick. Dip it into the primer. Stir gently for about 30 seconds. Look for any clumps or separation. If you see these signs, the primer may be bad.

Use a proper technique to ensure accurate results. Always check the date on the can. Old primer can spoil even without visible signs. Store primer in a cool and dry place. This helps maintain its quality.

Look for unusual odors. A strong, bad smell indicates spoilage. Check for a thick texture. Good primer should be smooth and creamy. If it appears watery or grainy, it’s likely compromised.

Performance Test

To check if your Kilz primer is still good, apply a small amount. Use a brush or roller to spread it on a test area. Watch how easily it goes on the surface. If it spreads smoothly, it’s likely still usable.

Next, evaluate the drying time. Good primer dries within one to two hours. If it takes longer, it may be bad. Check the finish as well. A smooth, even finish indicates the primer is still effective.

Here are some signs of a bad primer:

• Clumpy texture
