KILZ Original and its variations are the primary oil-based primers offered by KILZ. They are specifically designed to block severe stains and seal in lingering odors.
KILZ offers both oil-based and water-based primers, depending on the specific product.
Whether your primer is water- or oil-based depends on its specific formula. Since I can't see the exact product you are using, you can quickly identify the base by checking the first few ingredients on the packaging or bottle.
KILZ 3 PREMIUM primer is a superior quality, fast drying, low odor, very low VOC, water-based primer-sealer-stainblocker. It has excellent adhesion and provides a mildew resistant coating making it ideal for use in moisture-prone areas.
KILZ® ORIGINAL. Interior Primer. KILZ® ORIGINAL Oil-Based Primer is a powerful stainblocking formula that blocks most heavy interior stains including water, smoke, tannin, ink, pencil, felt marker, grease, and also seals pet, food and smoke odors.
Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces. Use under or over water-based or oil-based paints.
From Google: Kilz 2 is a water-based, fast-drying primer that can be used on multiple surfaces. It is good for adhesion, mildew resistance, blocking light to medium stains, and simple color changes. Kilz 3 is a heavy-duty, high-hiding primer that is good for blocking old dark colors and covering substantial stains.
Oil-based primers can be more toxic than standard paints because they often contain higher concentrations of solvents and release stronger fumes. This means they may produce more intense odors and increase exposure risks, especially in enclosed spaces without proper ventilation or protective measures in place.
Oil paints, as they age, tend to become brittle and less tolerant of movement, whereas latex paints retain a degree of flexibility. This disparity can lead to the oil-based paint layer cracking and peeling away from the latex base, especially in environments where temperature and humidity fluctuate widely.
Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.
The primary issue arises from the fact that oil and water do not mix. This means that if the primer isn't completely dry or if it's not properly prepared, the water-based paint may not adhere correctly, leading to problems like peeling or cracking.
The glossy surface of oil-based paints makes it so difficult for any other paint to bond. That's why, if you apply water-based paint straight to oil-based, it will flake and crack as the water-based paint pulls away. So, to get oil-based ready to paint over, you need to take away a lot of that gloss.
Additionally, water-based finishes have significantly lower levels of VOCs (volatile organic compounds), making them a healthier option for indoor air quality and a more environmentally responsible choice. Oil-based polyurethane, on the other hand, takes much longer to dry and emits higher levels of VOCs.
The "best" Kilz primer depends entirely on your project's specific needs. There is no single universal choice, but rather different formulas optimized for stain-blocking, adhesion, or everyday painting.
Oil-based paint is durable and glossy, making it ideal for high-traffic woodwork but it's being phased out due to environmental concerns. The strong odors, long drying time, and yellowing over time are key drawbacks of oil-based paints.
Yes, Kilz offers traditional oil-based primers, but the brand also manufactures water-based (latex) and shellac-based formulas.
Red is universally considered the hardest paint color to cover. Vibrant red pigments are highly transparent and inherently prone to bleeding through subsequent layers. Other notoriously difficult colors to cover include black, dark blue, dark green, and bright yellow.
Professional artists use both acrylic paint and oil paint depending on their style and the demands of their projects. Many artists who work in realism or portraiture prefer oil paints for their blending capabilities and depth of color.
Oil Based Primers
On the other hand, oil based primer is better for high-traffic areas, as they are able to form an extremely strong barrier between the primer and the paint. However, as time passes, these oil-based primers gather dust and dirt quite quickly. They are also not easy to apply consistently to your surface.
For the best results with KILZ oil-based primers (such as KILZ Original), ensure your surface is clean, dry, and free of dust or grease. Apply generously using a brush, roller, or sprayer without thinning. Allow it to dry for at least 1 hour before applying your topcoat.
Neither primer is universally "better," as they serve different purposes. Oil-based primer is superior for blocking stains, killing odors, and bonding to raw wood. Latex (water-based) primer is better for bare drywall, flexibility, quick drying times, and low-odor applications.
It's ready to brush, roll or spray and can be topcoated after one hour with latex or oil-based paint. Use KILZ STANDARD Primer on almost all interior surfaces including wood, drywall, plaster, brick, masonry and more.
Use an oil-based primer when you need superior stain-blocking, exceptional adhesion to glossy or slick surfaces, or to seal porous materials like bare wood. It is specifically required when transitioning from old oil-based paint to water-based (latex) paint, or when painting woods that bleed tannins.
