Can I use Kilz on concrete floors?

The article seeks to address the question “Can I use Kilz on concrete floors?”. It will also highlight the application method, advantages, disadvantages and drying time of Kilz on your concrete flooring.

Can I use Kilz on concrete floors?

Yes, Kilz may be applied on concrete floors. The product has excellent adherence and produces a high-quality finish on your surface. Due to its white hue it is appropriate for use on interior surfaces.

There are several advantages and application ways for utilising Kilz on your flooring, but it may also be utilised in various outside areas, such as brick/stone decorations. Always apply another coat of paint after applying Kilz to a cement floor to ensure long-term durability.

The purpose of this product is not to be a finish but rather a filler that enhances the natural colour of your colour choice without sacrificing it (perhaps due to the cement).

What is Kilz?

The KILZ Concrete & Masonry Bonding Primer is designed to enhance the adherence of masonry coatings to concrete and masonry substrates. This product offers a solid basis for coatings that are very resistant to water, high pH, and efflorescence when applied correctly.

Concrete, masonry, stucco, cinder block, and any porous stone or brick may all be painted with this product. Coated surfaces should not be used. Wood, metal, and silicone-treated surfaces are not suitable for use with this product. 

Can you use Kilz on floors?

Yes, a variety of floor types and purposes might affect the results you get when applying Kilz to them.

Kilz can be used on various kinds of flooring, such as hardwood, concrete, and tile, but it isn’t always the ideal option. For drywall, plaster, brick and mortar, tiles and other shiny surfaces inside your house, it is advisable to use kilz instead.

There are a variety of difficult-to-remove substances that might negatively impact the quality of your living area that Kilz can cover up remarkably effectively.

Kilz may also be used to cover over past colours on your surfaces (particularly beneficial if you’re planning on changing the colour of your walls, ceiling, or other surfaces). Concerns have been raised about the product’s potential toxicity for pregnant women, animals, and young children.

What are the cons for using Kilz for floor?

  • For various reasons, Kilz doesn’t appear acceptable as a floor covering.
  • It’s important to remember that the major application of kilz paint is to paint floors. In the case of pet urine, Kilz may be used to mask the odour and stain on your floor. It would help if you didn’t use kilz paint on your floors unless you’re dealing with such concerns.
  • It may take a while for the lotion to dry, and some people complain that the stench lingers in the room for days.
  • Adding a final touch to your subfloor is best done using Kilz first. There may not be enough shine in water-based kilz primer for most flooring. Instead, the product serves a more practical purpose by protecting the most delicate parts of your flooring from damage and moisture deterioration. 
  • Moreover, it wouldn’t endure long if it was often walked over.

How long does it take Kilz to dry on the subfloor?

In general, kilz may take anywhere from 30 minutes to an hour to cure fully, but other variables like room humidity and how much paint is being applied might alter this drying time.

Kilz that is water-based dries faster than kilz that is oil-based. Even if the air is well vented, the odour may remain for a few days. As a result, plywood subfloors are ideal for kilz application since they suck in the product and give a stable foundation for your flooring.

Although kilz may be used on concrete and wood subfloors, you should check with the manufacturer (or an expert) to see a better solution for your requirements.


How can I prepare the application for Kilz on my floor?

  • The surface must be properly prepared.
  • Before priming, new concrete must have been cured for at least 30 days.
  • Allow the patching to dry before moving on.
  • It is not recommended that this product be used on surfaces that have already been coated. Remove any loose or peeling paint before applying a new coat of paint. Use KILZ Concrete & Masonry Paint Stripper to remove any previous coats.
  • Use KILZ Concrete & Masonry Cleaner & Etcher to clean and etch the surface before applying primer.
  • Spritz a few droplets of water upon it. It is ready for use if the surface absorbs the water fast. Strip or re-etch if not absorbed. Be sure to follow all of the directions on the label.

What are the steps involved?

  • Apply at temperatures between 50 and 90 degrees Fahrenheit for the greatest effects.
  • Before and during the application, stir the primer completely. DON’T ADD WATER.
  • Use a high-quality pump sprayer, nap roller, nylon/polyester brush, or pad applicator.
  • It should cover anywhere between 350 and 500 square feet of floor space.
  • Any commercial brush cleaner will do. If you clean your brushes or other applicators with soap and water, they will be sticky. 
  • All contaminated absorbents, containers and unused products must be properly disposed of according to all applicable laws and regulations.
  • Do not flush this down the toilet. Inquire about recycling and waste disposal options with your local garbage collection agency.
