What Is Kilz Paint? Which Cans Are Paint, Which Are Primer

Most cans sold under the Kilz name are primer, not paint. Only three product lines are real paint: Tribute for interior walls, Complete Coat for inside and out, and Porch & Patio for floors. Grabbing the wrong one costs you either coverage or stain blocking. This guide decodes every can, shows dry and recoat times, and walks through using Kilz paint correctly.

What Is Kilz Paint? Mostly a Primer Brand

When people say Kilz paint they usually mean a white can that hides stains. That can is almost always primer. Kilz built its name on stain-blocking primers, and its paints came later. If your project is a stain, odor or bare-wood problem, you want a primer, and our step-by-step guide to using Kilz primer covers that side. If you want color on the wall, this page is the one to follow.

The table below sorts the whole lineup so you can tell at a glance which cans are paint, which are primer, and how long each waits between coats. Times are the manufacturer figures at standard room conditions, and cool or damp air makes all of them longer.

Every Kilz Can Decoded: Paint vs Primer

Can	What it is	Dry to touch	Recoat	Coverage per gallon
Kilz 2 and Kilz 3 Premium	Water-based primer, sealer, stain blocker	30 minutes	1 hour	See label
Kilz Restoration	Water-based primer for heavy stains	30 minutes	1 hour (topcoat)	300 to 400 sq ft
Kilz Original	Oil-based primer	1 hour	24 hours before latex topcoat	See label
Kilz Complete	Oil-based primer, interior and exterior	90 minutes	2 hours	See label
Kilz Tribute (satin)	Interior acrylic paint and primer	1 hour	2 hours	Up to 400 sq ft
Kilz Tribute (semi-gloss)	Interior acrylic paint and primer	2 hours	4 hours	Up to 400 sq ft
Kilz Complete Coat	Interior and exterior paint and primer, semi-gloss	2 hours	4 hours	300 to 350 sq ft smooth, 200 to 300 rough
Kilz Porch & Patio	Acrylic latex floor paint, low-lustre	1 hour	4 to 6 hours	300 to 400 sq ft smooth, 200 to 300 rough

The oil-based row is the one that trips people up. Kilz Original is touch dry quickly, but the label wants a full 24 hours before a latex topcoat goes over it, while the water-based primers are ready in about an hour. Treating them the same is a common reason for a topcoat that peels or lifts. For the brand head-to-head, see Zinsser vs Kilz primer.

Which Kilz Do You Need for Your Project?

Match the can to the problem, not to the color of the label.

• Changing wall color over clean paint: Tribute. It is paint with primer built in, so you skip a separate priming coat on sound surfaces.
• Smoke, water or heavy stain on a ceiling or wall: a Kilz primer first, such as Restoration (water-based) or Original (oil-based), then your topcoat.
• Exterior trim, siding or doors: Complete Coat, which is rated inside and out and is sold as a paint and primer.
• Porch floors, steps and decks: Porch & Patio, a floor enamel made for foot traffic.
• Bare wood with knots or tannin: a stain-blocking primer under the paint. Our guides to wood primers and shellac-based primers compare the options.

One limit worth knowing: the Tribute label says it covers light to medium stains and light-to-dark color changes. That is a real range but not an unlimited one, and the Kilz primer as paint question goes the other way, since primer left as a topcoat is not built for scrubbing or sunlight.

How to Use Kilz Paint, Step by Step

These steps apply to Tribute indoors and Complete Coat outdoors. Check the can for any rule that differs on your product.

1. Check the temperature: Complete Coat is rated for surface and air temperatures of 50 to 90 degrees Fahrenheit. Do not start a job outside that window.
2. Clean the surface: remove dust, grease and loose paint. Kilz paint bonds to clean, sound coatings, not to dirt or flaking paint.
3. Patch and sand: fill holes, then scuff glossy old paint so the new coat grips. Spot-prime bare patches with a Kilz primer.
4. Stir the can: the label says to mix well before using, because pigment and solids settle.
5. Cut in first: brush the corners and edges, then roll the open areas while the edge is still wet so the lap marks blend.
6. Wait for the recoat window: 2 hours for Tribute satin, 4 for Complete Coat. Recoating early drags the first coat.
7. Apply a second coat when needed: a big color change or a rough surface usually earns one.

If your surface is already coated with a clear finish, check the guide on painting over polyurethane before you start, and use sanding between coats for the grit and timing.

How Much Kilz Paint to Buy, and What It Costs

Coverage figures on the label assume one coat on a smooth surface. Real walls take more, so work the number before you shop. A 12 by 14 foot room with 8 foot walls has about 416 sq ft of wall. Subtract a standard door (about 21 sq ft) and two windows (about 30 sq ft together) and you have roughly 365 sq ft to cover. These dimensions are an estimate, so measure your own room.

Scenario	Area to paint	Gallons at 400 sq ft	Gallons at 300 sq ft
One coat, 12 x 14 room	about 365 sq ft	0.9	1.2
Two coats, same room	about 730 sq ft	1.8	2.4
Two coats plus trim and a ceiling	about 1,000 sq ft	2.5	3.3

Cost per square foot follows from the can price. At the listed price of $72.31 for a gallon of Tribute satin white (checked on 2026-10-07, and color, sheen and seller change it) and the 400 sq ft label figure, one coat costs about 18 cents per sq ft, rising to about 24 cents if you only get 300. A gallon of Porch & Patio at a listed $40.48 over 300 to 400 sq ft works out to roughly 10 to 13.5 cents. Paint-and-primer costs more per can because it replaces a separate primer coat, so compare the total job, not just the can.

Safety and Cleanup

• Ventilate: open windows and run a fan, even with low-VOC cans. Oil-based Kilz primers have a stronger odor than the water-based ones.
• Homes built before 1978: old paint can contain lead, and sanding it makes dust. Test first and follow the EPA lead guidance before scraping or sanding.
• Porch & Patio: the label warns sealed surfaces can be slippery when wet and says not to use it where car tires will drive.
• Clean up: water-based paints and primers wash out with soap and water. Oil-based primers need mineral spirits, and rags soaked in oil-based product should be laid flat outdoors to dry before disposal, because they can heat up and ignite.

Common Kilz Paint Mistakes

• Using a paint-and-primer to block heavy smoke or water stains instead of a stain-blocking primer.
• Topcoating oil-based Kilz Original with latex after 1 hour instead of the 24 hours the label asks for.
• Putting standard interior Tribute wall paint outdoors. Only the separate Tribute trim, door and cabinetry semi-gloss is labeled interior and exterior.
• Painting in cold or damp air. Complete Coat’s 50 to 90 degree range is a real limit, and times in the table assume room conditions.
• Buying one gallon for a two-coat room and running short at the last wall.

Frequently Asked Questions

What is Kilz paint used for?

Kilz paint is used to cover a color change and seal the surface in one product. Tribute is an interior wall and trim paint with primer built in, Complete Coat works inside and out, and Porch & Patio is a floor and deck enamel. Stain blocking on heavy stains is the job of Kilz primers, not these paints.

Is Kilz a paint or a primer?

Both, depending on the can. The Kilz name is best known for primers such as Kilz 2, Kilz 3 Premium, Kilz Original and Kilz Restoration. Kilz also sells true paints: Tribute, Complete Coat and Porch & Patio. Read the front of the can for the words Paint and Primer, or Primer Sealer Stainblocker.

Can you use Kilz paint outdoors?

Only the exterior-rated cans. Complete Coat is sold as an interior and exterior paint and primer, with an application range of 50 to 90 degrees Fahrenheit. Porch & Patio is rated for interior and exterior floors, decks and siding. The standard Tribute wall paint is interior only, though Kilz also sells a separate Tribute trim, door and cabinetry semi-gloss labeled for interior and exterior use.

How long does Kilz paint take to dry?

It depends on the product. Tribute satin dries to the touch in about 1 hour and can be recoated after 2 hours, and the semi-gloss takes 2 hours to touch and 4 to recoat. Complete Coat is touch dry in about 2 hours and recoats after 4. Porch & Patio is touch dry in 1 hour and recoats in 4 to 6 hours.

Do you need to prime before using Kilz Tribute?

Usually not on clean, sound, previously painted walls, because Tribute is a paint and primer in one and covers light to medium stains and light-to-dark color changes. Prime first when the surface has heavy stains, bare patched areas, or smoke and water damage, using a Kilz stain-blocking primer under the paint.

The Bottom Line

Kilz paint is a smaller family than the name suggests. For color on clean interior walls, use Tribute. For exterior trim and doors, use Complete Coat, and for floors use Porch & Patio. For anything stained or bare, put a Kilz primer down first. See mold-killing primer vs Kilz if mildew is part of the problem.
