The paint for a basement floor has to have a lot of ‘solids’ in the solution, and that does cost a little more, but it’s very much worth it. Using the best basement floor paint is a no-brainer and a big thank you to gravity for making a painter’s life great.

We love Benjamin Moore’s basement floor paint Tough Shield as it covers a lot and when we want durable anti-slip floor paint, we go with the excellent Sure Step. We will also talk about the best budget choice and the best decorative concrete paint.

On priming, INSL-X wrote in a comment: “Concrete Floors – Thin the first coat of Tough Shield Floor & Patio Coating with one pint of water per gallon. Allow 24 hours dry time then apply one or two coats as it comes from the can. ” For wood, prime with Aqua Lock Plus and wait 24 hrs before painting. Metal: prime with metal primer.

Read the can label or read the product page if you are buying online, about the VOC content. We wear respirators anytime we are not sure what we are breathing. We simplified the crazy world of respirators for you in a short post. For almost all painting projects you’ll get by with the half-mask which comes without filters (model 6100=small, 6200=M,6300=L), and then the filter kit which has both dust and chemical filters that you can use together or separately.


Painting basement floors: How-To, summary in 5 steps:

 

  1. Cut. Go all around the edges and posts etc first.

  2. Roll. Just pour the paint on the floor! Make a puddle and use it as your ‘bucket’. We use an adjustable pole and “do it standing up”. It’s so easy. Biggest tip: don’t use cheap roller covers: they shed lint and will totally ruin your work. Apply evenly and fully.
  3. Let it dry a few hours according to the label, then test if dry (wear socks, no shoes).
  4. Second coat? Probably not necessary if you are using the best basement floor paint. Use a bright light to see up close. Often the answer depends on your color choice: grays are great and reds you’re dead. The cut may not need 2 if the rolled section needs 2. The paint can instructions tell you how long to wait between coats but don’t wait too long or you will not have good bonding between coats!
  5. Is it really dry? Use your fingernail to test how soft it is If it is not dry, wait!

We detail all steps including preps and primer in our section below on How to paint basement floor.

Before painting basement floor:

  • Do not try to paint a basement floor that gets wet from any direction: it’s a world of hurt. See the concrete moisture test below.
  • Paint on concrete does not cover as much area as wall paint (little grooves swallow paint). You need to buy the best basement floor paint and calculate the quantity carefully (rough surfaces swallow up paint).
  • Cannot stress it enough: the best basement floor paint prevents future headaches! Floors get abused. Why repaint after only a handful of years? Uff.
  • Painting a garage floor? You need garage floor paint. See the bottom of this post.

Pug on painted basement floorBe happy: painting basement floor goes very fast. Even very big areas (after prep) will take only an hour or so. Plan carefully but be aware that many photos you will see around the internet are taken right after the floor was painted so, of course, it looks great. How about 5 years later?

Check for moisture coming through the floor: using a very sticky tape, fix a 2-3 foot square of plastic wrap down tightly—no air gaps (floor must be clean and not visibly damp). One day or two later, if you have moisture trapped inside the film, you cannot paint that floor. Contact a builder to see if you can rectify this problem. There are some specialized sealants, but you must find what the source of H2O is.


How to paint basement floor: detailed steps

Prep: most of the work is here
    • Think it through before painting basement floor. Plan the moving of the furniture if you cannot move it into another room. You may get paint on things, so think about covering nice things with plastic drop cloths. Use tape to keep in it place with tape that will not leave a glue mark green painter's tape. If you have old cloth (even cardboard or padding). Lay furniture on sides or top not legs (less pressure) to keep objects from sticking.

    • We have listed all of the tools you may not have, such as scrapers, rollers, brushes etc. Think clean-up will be hard? Nope. We have great posts on how easy clean-up can be. Check it out in the Tips section.
    • Check your exact product label, but most floor paints specify a 3/8 inch nap roller cover.
    • Remember:  the final look is only as good as your prep job. After you are done your prep: paint cannot really hide any sins! Sand (or as mentioned below for concrete, wire brush) old paint that won’t scrape off (feather the edges), and sand any wooden floors (use assorted sizes-on this page select some course and some medium grit ), and prime* the unpainted spots: use a quality primer (Ultra-Spec) for bonding reasons: remember this is not just for looks—it has to be very tough.

      * Read the label on your choice of paint: some do not require a primer.
    • Concrete floors: already painted? Prep with a wire brush: get a good one because the wires fall right out of the low-budget ones. Wash the bare spots well (see unpainted concrete below). A bad peeling problem is probably due to poor prep last time or moisture getting in the rock,which is probably unpaintable.
    • Uneven floor in spots? Use floor leveler. DAP is our friend: this size bucket covers perhaps up to 10 square feet if spread not-too-thick (not for garage floors). Measure before you buy. Does the leveler you have need a primer? Good to check now. The Dap above does not specify: so we prep it like new concrete (below).
    • Lots of furniture to move? No? Go to step 9. Yes? Maybe do the job in sections: over a longer time period so you don’t have to move everything out.
    • To begin, prep and then clean the section you will paint LAST. When you clean you will spread dust so only clean once when the prep etc is done. Prep and clean your staging area (with paint buckets etc) and furniture holding areas; move things onto that section.  Cover them and the floor you cleaned, then clean the area you will start painting first. Whew. Easier than it sounds here!
    • Nearby your storage section, place soft (old) blankets you will use later on the freshly painted section for when you paint your staging/holding areas. These cloths/pads will go under your furniture and above the just painted sections, protecting the soft basement floor paint.

    • Unpainted concrete floors should be acid washed first even if not new. You can use the toxic muriatic acid which is nasty. But even with the standard non-muriatic choice from Rust-Oleum eco-friendly to plants, which gives the same result as the acid concrete floor etcher, we wear goggles and a respirator!! One gallon does 500 sq. ft. See warning on muriatic acid below*.
    • If you go with real acid, remember, never add acid to a large amount of water, only add water to acid (prevent acid splash). Ventilate the room and wear that respirator!
    • Pour and push the solution around the floor with a scrub brush that fits on a broom screw pole.
    • Rinse either solution three times with water to deactivate the acid (and this actually removes the impurities). A wet/dry shop vac is good for this, or use rags (with rubber/nitrile gloves!) A drain in your basement floor will be helpful here or you have to use a mop and bucket. Test that your drain is not blocked first!
    • Let the concrete dry completely. Fans will help. Unpainted concrete may need a masonry primer depending on the specs of the paint you want to use: Our go-to masonry primer is the best: Ultra-Spec is the contractor line of paint from Benjamin Moore and is intended for garage and concrete floor priming.

    • Do your cleaning in this order: vacuum, mop, then use a damp cloth for the edges. Try to get all the small bits of dirt: if it gets in your painted floor, it will lead to paint chipping in time.
    • After cleaning and priming, caulk/fill cracks. Large gaps should not be caulked but filled with special water-tight concrete crack filler,  or go for 6 tubes of  cement caulk. Caulk needs no priming but crack fillers might. But beware…
  1. Start painting: the easy part
    • Remember that “exterior only” paints should not be used indoors they are very toxic and harmful as they off-gas for months. Read more.
    • Open some windows or somehow set up proper ventilation, unless you have VOC-free paint (tints added to VOC free paints make it into non-VOC-free!) Here is our look at VOCs.
    • Plan your painting direction: know your final way out (add your own joke about being painted into a corner).
    • Cut. Go all around the edges and posts etc first. Normally we ALWAYS roll before we brush (cut), but here we never do that. We have written a post on how to easily clean a brush.
    • Roll: usually we say roller pans suck-use a bucket. Here we say, don’t even use a bucket! Just pour the paint on the floor! Ah, The Dude Abides. Make a puddle and use it as your bucket/pan. It’s so easy.

    • Biggest tip: don’t use low-budget roller covers: they shed lint and will totally ruin your work. This shows how trying to save money is very expensive! Keep your paint from making puddles, but apply evenly and fully. The small Purdy roller shown here is an excellent low-cost choice, but a little slow if you don’t care about speed. Great for walls behind toilets and radiators.
    • In a few hours, the paint will probably be ok to walk on (check can label), but still quite soft so wear socks or check your shoes for little pebbles etc.
    • Does it need a 2nd coat? Maybe yes even if you are using the best basement floor paint. Use a bright light to see up close. Often the answer depends on your color choice: grays are great and reds you’re dead. Is there a difference between coverage in the brushing and the rolling? The cut may not need 2 if the rolled section needs 2. The paint can instructions tell you how long to wait between coats but don’t wait too long or you will not have good bonding between coats!
    • Is it really dry? Use your fingernail to test how soft it is If it is not dry, wait!
    • Lay your blankets out (from step 1) and on that carefully place your furniture (maybe lay furniture on flat edges rather than legs to spread out the weight).
    • The next day, check that no blanket/padding is sticking. If anything pulls up the fresh paint, you have to touch up.
    • Cut, roll unpainted sections, as above. Don’t be afraid of cleaning roller covers: it’s easy. Summer curing times can be weeks and in winter time a few months! Treat it gently for a while!


Garage floor paint: good news and bad news. Which one do you want first?

Bad? Why do they always say bad?

The bad news is that rubber tires will pull up even the best basement floor paint.

A long-lasting choice is, of course, epoxy paint, but you have other options for garage floors like Armor All mats, and the 2-part epoxy (just below) is one, but these days you do not have to use a 2-part product and be forced to work very quickly before it turns into unworkable mush-goop.

There is a new product Kilz Concrete Garage Floor Paint —a one-part epoxy, so cool. Sliver/Gray or Slate Gray only.

Another product that has a great rating is Rust-oleum Epoxy Shield. It’s a 2-part epoxy-the real thing. Comes in red, tan or two grays, but you can add the retro-look sparkling decorative chips. Ok, sure. All directions are clear.

Epoxy paint tip: if you use epoxy paint, obviously, follow directions… but they may not tell you: keep your brush and roller strokes in the same direction. … and wear that chemical respirator!

Drylok from UGL is a one-step concrete and/or garage floor paint. It does not need a primer, but for best adhesion, I would apply the Benmain Moore Masonry Primer above. Dryloc is fine going over painted surfaces so you will have fine adhesion with no primer, but it would be better with a primer, in our opinion.

It comes with tints to pick your color, which is rare in a concrete floor paint. The Dover gray linked here is the go-to color, but get the white if you want to tint it. (Tints on the product page). Water-based, covers about 400 sq ft, but with all concrete, expect less for rough surfaces (of if unprimed).

Benjamin Moore also sellsGarage Guard about 110 dollars for 1 and one-quarter gallons (a quart of hardener comes with the main part). It’s a water-based 2-part epoxy: just like the older stuff. Ask me about the time I sprayed it—oh what a day that was—but it is a great product. This will make a great basement floor paint.

A clear epoxy sealant from Rust-Oleum would increase the longevity on any floor including garage floors. It is a 2-part epoxy with anti-skid components added. It covers 500 square feet of the previously painted floor, and covers up to 200 to 250 sq. ft. on bare concrete, 450 to 500 sq. ft. on previously treated concrete.

  1. So, after researching tons I didn’t come across the tip about the roller cover quality until now, when I’m researching how to fix the lint in my paint job. Any suggestions on how to fix it? Porch and floor poly eurothane gloss.

    • Hi. Those companies suck. Why make crappy tools that hurt others? Anyway, you have to sand it off…so sorry to tell you.

      If you send a pic to my email address, I’ll post here –I’ll block personal info, faces— I’d like to show people what can happen with budget rollers… if you can…
      So… my advice:
      Rent a floor sander from Home Depot or some place..or just go on hands and knees. Look at the tool list post here for good knee pads: for cleaning the house too… I use mine all the time even now in retirement.
      So after sanding, if wood use oil primer then Ben Moore deck paint. your paint store will have suggestions too… I hope you have BM or Sherwin W store nearby…others… meh, lower quality. Don’t trust Home Depot paint dept: but the products they have are generally ok.
      ps, get a 2nd roller cover if you do oil primer: we don’t clean oil rollers…ick

  2. Brad, thank you so much for the advice! When you sand it, do you mean sand off the entire paint job or sand lightly to buff the lint? Also, my particular site is concrete slab. Would you recommend a microfiber roller or simply a quality roller?

    • Hi again. Microfiber holds less paint per dip, but it would be fine. I know you’ll choose a quality one!

      I’d sand a section, re-paint, and see if I can live with it. If not, do another section,sanding more. If it is fresh, it may be too soft to sand. You might have to let it harden…Warmer weather coming will help. Thanks for the photo!
      Brad
      Lint came off a cheap roller cover and ruined this basement floor paint job! Now the sanding begins.

  3. I’m waiting to paint my concrete floor in the basement but I also want to paint some stencils over the top because it’s going to be a functional room. Once I’ve used a good concrete paint would you say I could paint over the top with standard floor paint? I want to use a few different colours and I already have a couple from a different project.

    • Concrete is tricky to paint: the surface must be properly prepared, and then you would want a very durable paint as to re-paint it later can be a big mess if it starts flaking. Generally though, if it is done right, it will last for many years of use. In the post above are the steps to ‘etch’ the concrete if it is smooth or new: this creates a non-smooth surface and removes the calcium sulfate… you have to rinse the acid well ( a few times). I like the Benjamin Moore 2-part epoxy paint for garages, GarageGuard, but it does not come in many colors…but it does come with color flakes you toss in the air over it while it’s wet. Very nice idea. Perfectly suitable for indoors, but there is a stronger smell than some modern paints…but you won’t be repainting anytime soon. With your existing paints, we cannot say how long it will last. To me, color takes a back seat to long life. Also, have a look at Sure Step by B.Moore as is Tough Shield… both will really last. I don’t have experience with many other floor paints as I’ve heard too many horror stories! Good luck.
