Kilz manufactures both water-based and oil-based primers. If you plan on painting with a water-based latex paint, you should prime your walls with a water-based primer. Kilz offers many water-based paints that claim to provide a range of coverage qualities and benefits to your painting surface including providing an even surface to apply your finishing coat, covering porous surfaces, and covering spackle blemishes and stains. Kilz latex water-based primer can be used beneath an oil-based coat. This provides a range of flexibility for the user. Kilz also offers paints for exterior surfaces as well.
Apply an oil-based primer if your finishing coat will be oil-based as well. The Kilz oil-based primers have a greater ability to block stains and odors such as cooking grease or nicotine, which tend to stick to the walls and provide a pungent odor in some homes. For those who want to benefit from the superior hiding ability of oil-based paints but cannot stand the odor associated with it, Kilz offers an odorless oil-based primer.
Kilz manufacturers other products other than primers even though that's what they are generally known to do best in the painting industry. Kilz offers products such as a ceiling paint to provide coverage for most common ceiling stains such as water stains with minimal spattering. The primer dries to a flat white and can be applied to every interior surface with the same efficiency. The colors changing primer products changes from pink to white as it dries to make sure you never miss a spot. This is ideal for ceilings as well where you usually apply a white primer to a white-colored ceiling.
Many paint companies offer a primer and painting combination that eliminates the need to apply a primer such as Kilz. The ability to hide and cover porous surfaces are often debated by old-fashioned paint professionals who believe a good primer is the only way to start with an evenly coated paint. The Kilz primer will soak into the wall and provide painters with a clean base for which to apply their finishing coats of paint. Other primers are available that will do the same type of job as Kilz. The only exception being Kilz specializes in primers while most other companies specialize in finishing products.
