DO NOT THIN if using a roller or brush; however, if using a sprayer and thinning is required, thin with water at a ratio of no more than 8 oz. per gallon.
I sprayed kilz with the harbor freight LVLP sprayer without diluting it and it worked pretty well.
The company says: ``Best results for stain blocking are obtained with no thinning. However, KILZ 2 Latex primer and KILZ Premium primer may be thinned up to 10% per gallon with water.''
The Kilz label indicates using mineral spirits for cleanup; that covers a wide variety of products including paint thinner, literal mineral spirits including odorless, etc.

Prepare the primer
If it is on the thick side, you should dilute it to ensure effortless application with your paint sprayer.
KILZ 2 ALL-PURPOSE Primer (Previously KILZ 2 Latex) is a fast-drying, water-based, multi-surface primer-sealer-stainblocker with excellent adhesion, mildew resistance, sealing properties and very mild odor.
Mineral spirits are a more refined paint thinner distilled from petroleum. The main benefit is that the odor isn't as strong because it doesn't contain other chemical additives, like benzene. However, because they're refined, they aren't as powerful as other kind of paint thinner.
Kilz should be applied at about 4.6 mils thick wet, you can learn how to check wet mil thickness in our guide here. Coverage for brush or rolling is 300 to 400 Sq feet per gallon.
Depending on how strong or bold the previous color is, it may be necessary to apply more than one coat of primer. However, it is not necessary to over apply the primer with so many coats. As long as the primer applies uniformly over the previous color, then one or two coats should be sufficient.
Master stock primers newly suspended in water should be allowed to sit at room temperature for 10 minutes before they are used for working stock dilutions. Mix well before making working stock dilutions. Dilute the primer master stock in a sterile microcentrifuge tube 1:10 with sterile molecular grade water.
The stain provides a durable, water-repellent finish that also protects against the sun's harmful UV rays.
AVOID CONTACT WITH SKIN AND EYES AND AVOID REATHING OF VAPORS AND SPRAY MIST. WEAR EYE PROTECTION AND PROTECTIVE CLOTHING. USE ONLY WITH ADEQUATE VENTILATION. To avoid breathing vapors and spray mist, open windows and doors or use other means to ensure fresh air entry during application and drying.
The EPA registered active ingredient creates a mold and mildew-resistant film that protects the primer film from mold and mildew growth. KILZ MOLD & MILDEW Primer will block most medium to heavy stains including felt marker, grease, ink, pencil, tannin and water stains.
Do not thin for stainblocking applications. A small amount of water may be added for other spray applications.
Depending on the brand, paint thinner can be made of solvents such as methyl ethyl ketone, toluene, naphtha, and of course, acetone. Unlike “paint thinner”, “acetone” does not directly show the applications of this solvent. However, it boasts a large range of applications, including being a thinning agent.
No, do not pour mineral spirits down the drain. Anything flammable should be kept for proper disposal—either use it up the way it was intended, or give it to someone else who will use it (craftsman of some kind) or dispose of it at a household hazardous waste disposal event.
Original Kilz Primer allowed more seep through when put in two coats to two different walls in the same area, whereas Zinsser provided superior coverage.
Coverage: 300-400 sq. ft. (28-37 m2) per gallon depending on application method and surface porosity.
Kilz is water based. The manufacturer recommends: "Do not thin for stainblocking applications. A small amount of water may be added for other spray applications."
Apply as supplied using a brush, roller or sprayer. Do not thin. Stir thoroughly before and occasionally during use. Prime the entire surface to ensure a uniform appearance of the topcoat.
Why don't painters use sprayers? Sprayers require significant prep work to protect non-painted areas from overspray. They also need thorough cleaning post-use. Some painters prefer the simplicity of traditional methods like brushes or rollers.
