KILZ Porch & Patio Floor Paint - Slate Gray

The KILZ Low-Lustre Enamel Porch & Patio Paint really impressed me. It offers great coverage — I didn’t need as many coats as expected — and the neutral gray color is spot-on: clean, modern, and not too dark. It was easy to apply with a roller and brush, and it dried quickly, which made the whole project faster than I anticipated. Highly recommend for any porch or patio update!

Pros: this is a typical, modern, high-tech paint which ticks off all the check boxes: - Does not drip or run from the brush during application - Lays on silky smooth - Easy to go back over spots to cover up brush strokes while wet, and the new paint blends in well without streaking - Hides dark paint exceptionally well - Is self leveling and shrinks slightly when dry, which helps to hide brush strokes - Dries to the touch quickly, well within an hour - Lays on a nice, satin sheen which is not slippery when wet, so a good choice for outside stairs - Brushes clean up like new with soap and water Con: - The silver gray is more like off white! When I opened the can I thought the paint wasn't mixed well but mixing did not change the color. If you have white railings you are best off with the darker grey color to provide some contrast. Only reason I kept the silver gray was rain was due in two days and I had to paint an outside repair with bare lumber, but at least the color is cool when the sun beats down. I used this Kilz paint to cover dark, rust red stairs and it hid the color with one coat! I did put on one rather heavy coat. When you first apply the paint it seems to cover extraordinarily well, then it gets a bit transparent as it dries, but when fully dried the old paint was effectively hidden with a solid, matte finish. To cover nail head holes and cracks just apply a bit more paint to the edge of the brush, then go back and dab those areas while the paint is setting. The paint does shrink when dry so you may have to dab up those areas again, but it's good that the paint shrinks in place to seal well and does not lay on too thick. This is my first experience with Kilz paint. Problem with buying paint at Home Depot or Lowes is the bewildering variety but you have to dig through the web to find reviews. By buying on Amazon it's easy to find paint with a high number of good reviews, and the free freight doesn't hurt either.

Great product. Better price than the home improvement stores. The quality is excellent and easy to apply.

Painted garage ceiling and walls. Went on easy. Fairly easy cleanup. One coat did it, same color. Has resisted mildew, moisture, pretty low and high temperatures. Definitely worth the money. I added sand mix to cover up tiny cracks

Great product. Looked great when done

I'm using this product essentially as a primer for my pool deck which I plan to next treat with KILZ Over Armour. It was very easy to work with, spread easily and gave a very nice finish. I measured the paintable surface at about 270 sq. feet which put it right in the middle of the range given on the can (200 - 400). I used the entire can with less than an ounce leftover. The deck was fairly weathered with some areas of darkening and some splintering. I first scrubbed with a wire brush using a bleach solution, rinsed clean then lightly sanded the most splintered areas. This removed most but not all of the dark areas. The paint covered everything nicely and resulted in one evenly colored coat. I highly recommend the product especially at the price offered. Only wish there were more color options but since I'll be covering it anyway it's no big deal. The reason I only gave it 3 stars for durability was obviously because I just put it on so I have no idea.

We have a very large older deck that needed a facelift. We have used various stains and paints and every time it looks good until it rains, snows or the sun beats on it, then it is peeling, chipping, sticking to your bare feet, pretty much a mess. We used the Kilz paint in July 2024 - this picture is from Oct. 1, 2024- and so far we are very impressed. It hasn't peeled away or chipped and it isn't wearing out where we walk daily. I know it's only a few months, but so far it has been better than all the others. We prepped our deck by power washing it and letting it really dry out, then we put on one really heavy solid coat. We used 8 gallons to cover our deck. It covered really nicely. The paint was thick and went on easily. It dried super fast in the July sun. I'll try to remember to update this after some slush or snow this winter. I am hopeful I will only need to do minor touch ups. That would be amazing if it holds up through 4 seasons and only needs basic maintenance. **Update: I added a picture from June 2, 2025. As you can see this paint weathered far better than any we’ve used before. We have had zero peeling. It really held up great over the winter. Highly recommend.

Great paint for my deck

Painted my trailer floor with this paint did a few coats and it looks tough and will last hopefully. Will be riding motorcycles over it for travelling so we’ll see how it holds up. Was easy to apply and covered well.

We had an older deck, with water damage. This worked so well, and made it look like new.

I Received an open item paint spilled, dripping and stained our floors.

bonjour, c'est la deuxième fois que j'achète ce produit et je suis entièrement satisfait. Hello, this is the second time I have purchased this product and I am completely satisfied.

Hats off to the KILZ chemists on this product. I applied it on both previously stained/painted concrete and wood deck with ease. It is very user friendly being a waterborne acrylic. Application is buttery smooth yet sticky with either a brush or a roller. One coat almost does the trick,but I suggest 2 coats for perfection. Dries very fast and virtually odourless. I suspect it will prove to be a durable paint in future.
