Is Kilz Tintable? Yes — Up to 2 Oz of Colorant Per Gallon
Most Kilz primers accept up to 2 ounces of universal colorant per gallon — but Kilz Original’s oil-based formula needs solvent-based tint, not the water-based tint used in Kilz 2 and Kilz 3 Premium, and aerosol Kilz cannot be tinted at all. Mixing the wrong tint type makes the color ball up and separate instead of blending. This guide covers the exact ratio, which Kilz lines tint well, and how to avoid a ruined batch.
How Much Colorant Can You Add to Kilz Primer?

Mixol Universal Tints, 12-Piece Kit (#13-24) – $34.99 A universal colorant kit for tinting Kilz at home when you’re doing a small batch or don’t have a paint store nearby — stays under the 2 oz-per-gallon ratio this guide covers, since each bottle doses in small increments.

Kilz 2 All-Purpose, Kilz 3 Premium, and Kilz Original can each be tinted with up to 2 ounces of universal colorant per gallon, according to Kilz’s own product guidance. Go past that ratio and the primer’s stain-blocking and adhesion properties can suffer, even if the color still looks fine in the can.
Paint stores add colorant with a calibrated tinting machine, which doses it more accurately than mixing by hand. If you’re tinting at home instead — no store nearby, or just a small touch-up batch — a universal tint kit like Mixol lets you add small, controlled amounts directly into the can.

Which Kilz Primers Can Be Tinted?
Kilz’s water-based lines — Kilz 2, Kilz 3 Premium, Kilz PVA, and Kilz Restoration — all take universal (water-based) colorant. Kilz Original, the oil-based stain blocker, needs solvent-based tint instead. Put the wrong tint type into either base and the color balls up and separates rather than mixing evenly.
| Primer Type | Base | Tints With | Best For |
|---|---|---|---|
| Kilz Original | Oil-based | Solvent-based tint, up to 2 oz/gal | Heavy stain-blocking, smoke or water damage |
| Kilz 2 All-Purpose | Water-based | Universal tint, up to 2 oz/gal | Interior/exterior general use |
| Kilz 3 Premium | Water-based | Universal tint, up to 2 oz/gal | High-traffic areas, extra hide |
| Kilz Restoration | Water-based | Universal tint (confirm on label) | Heavy odor and stain sealing |
| Kilz spray/aerosol | N/A | Cannot be tinted | Small spot-priming touch-ups |
Always confirm the base type on the can label before buying tint — formulas are occasionally reformulated, and a mismatched tint type isn’t something you can fix once it’s already stirred in.
Can Kilz Be Tinted?
Yes — with one exception. Every Kilz primer except the aerosol/spray-can line accepts colorant. Spray primers use a pressurized delivery system that colorant additives can clog, so Kilz doesn’t support tinting them. For a small aerosol-sized job that needs color, buy a pre-tinted gray primer or switch to a brushed or rolled formula instead.
For the tinting rules specific to just one product line, see our guide on tinting Kilz 2 Primer.
How to Tint Kilz Primer
- Confirm your base type: check the can label for water-based (Kilz 2, Kilz 3, PVA, Restoration) or oil-based (Kilz Original) before buying tint.
- Buy matching tint: universal/water-based colorant for water-based Kilz, solvent-based colorant for Kilz Original.
- Measure carefully: stay at or under 2 oz of colorant per gallon of primer.
- Mix thoroughly: stir for at least 5 minutes, or run it through a store’s shaker for full dispersion.
- Test a small area: brush a swatch on cardboard or scrap wood and let it dry fully — wet tinted primer looks darker than the cured color.
- Tint lighter than your topcoat: this makes it easier to spot thin or missed areas once you start painting.

Common Kilz Tinting Mistakes
Most Kilz tinting problems come down to one of four mistakes: using the wrong tint base, exceeding the colorant limit, skipping the test swatch, or assuming wet color matches dry color.
- Mixing solvent-based tint into a water-based Kilz (or the reverse) — the colorant curdles and separates instead of blending
- Adding more than 2 oz of colorant per gallon — can weaken stain-blocking and slow drying
- Skipping a test swatch — primer color shifts noticeably as it cures
- Tinting to match the topcoat exactly — makes thin or missed spots invisible until the topcoat goes on
Kilz’s own tinting guidance recommends buying primer already tinted at the paint counter whenever possible — a store’s tinting machine meters colorant more precisely than hand-mixing at home, and reduces the risk of exceeding the 2 oz-per-gallon limit.

Frequently Asked Questions
Can Kilz be tinted to different colors?
Yes. Most Kilz primers accept up to 2 ounces of universal colorant per gallon, giving you a range of light-to-medium shades. Ask your paint store to tint it in the can using their calibrated tinting machine for the most accurate result.
What surfaces can Kilz be used on?
Kilz adheres to wood, drywall, plaster, masonry, and metal. It works on both interior and exterior surfaces, provided the surface is clean, dry, and free of loose material before application.
How long does Kilz take to recoat?
Kilz typically dries to the touch within 30 minutes and is ready to recoat in about 1 hour. Humidity and temperature can extend both times, so check the label on your specific Kilz product for exact figures.
Is Kilz suitable for exterior use?
Yes. Kilz Original and Kilz 2 are both labeled for interior and exterior use and hold up against outdoor moisture and temperature swings. Choose a product labeled for exterior use rather than an interior-only formula.
Can you tint Kilz primer yourself at home?
Yes, but use the correct tint type for your primer’s base — solvent-based tint for oil-based Kilz Original, universal or water-based tint for Kilz 2, Kilz 3 Premium, and similar lines. Stay under 2 ounces of colorant per gallon and mix thoroughly, or the color can separate instead of blending evenly.
Conclusion
Kilz primer is tintable across nearly its entire lineup, with a hard cap of about 2 ounces of universal colorant per gallon and one exception: aerosol/spray Kilz can’t be tinted at all. Match the tint type to your primer’s base — solvent for Kilz Original, water-based for the rest — stay under the ratio, and test a swatch before committing to a full batch.
