Industrial-Strength Waterproof Layout Chalk for the Most Demanding Jobsites

The Stanley FatMax Xtreme 47-827 5-Pound Red Chalk is engineered for professionals who cannot afford for their layout lines to disappear. This premium waterproof chalk is specially formulated to resist fading and bleeding, even in high-moisture or wet environments. Whether you are snapping lines on damp concrete or working through a humid morning, this chalk ensures your marks stay sharp and visible, providing the precision needed for framing, roofing, and general layout tasks.

Efficiency is built into the design of the packaging as well. The large 5-pound high-capacity bottle features a square shape to prevent it from rolling off slanted work surfaces or tailgates. The formula is optimized to eliminate clumping inside your chalk reel, ensuring a smooth, consistent flow and even coating on the line every time you pull. With its vibrant red pigment, this chalk provides a high-contrast mark that stands out against nearly any building material, making it a staple for heavy-duty construction and industrial use.

Key Features

  • Waterproof Formula: Lines will not fade, wash away, or bleed when exposed to rain or wet jobsite conditions.
  • Anti-Clumping Technology: Specialized powder consistency prevents clumping inside the reel for snag-free operation.
  • High-Contrast Red: Deep red pigment provides maximum visibility on concrete, lumber, and asphalt.
  • Square Bottle Design: Stability-focused packaging ensures the bottle stays exactly where you put it on the jobsite.
  • Easy-Pour Spout: Designed for quick, mess-free refills of all standard large-capacity chalk reels.
  • Professional Grade: Part of the Stanley FatMax Xtreme line, built for extreme durability and long-term permanence.

Pro-Tip: To achieve the cleanest line, give your chalk reel a few good shakes before extending the string. When working on highly porous surfaces, "snap" the line twice—once to clear excess dust and a second time for a razor-sharp, permanent mark.

Subtle smell, works well to pick up dirt!
Size: 8 Fl Oz (Pack of 2)
Has a nice, light smell when added to the Eufy C20 water. Smell is short-lasting and very subtle, so no irritation to the animals in the house. Easy to use, a small amount is recommended, and I find it works well. Very good value for long-lasting use. 1 cap/water refill, and the water is much nastier than it was when using just water. Very pleased with this purchase.

Easy cleaning and pleasant scent.
Size: 8 Fl Oz (Pack of 2)
It works very well with the robot vacuum cleaner. It cleans the floor without damaging it, leaves no residue or marks, and leaves a soft, pleasant scent. It lasts a long time and doesn't cause any problems for the device. A very good product; I would definitely buy it again.

So Worth the Purchase !!!
Size: 8 Fl Oz (Pack of 2)
I was a little hesitant to buy this since it’s a bit pricey for a floor-cleaning liquid. Still, I decided to give it a shot because the floor in my new apartment smelled stinky due to the pet urine from the previous tenant. It turned out to be totally worth the investment! The floor gets much cleaner with this product—the dirty water tank ends up way dirtier than usual—and the Eufy mop pads no longer smell bad like they used to without this liquid. Also, just a little goes a long way. I fill the tank to the max with water and add about 15ml of this liquid. The instructions say to dilute 10ml in 2 liters of water, and my tank holds about 2.5 liters. So with one bottle, I can refill the tank around 31 times—which is a lot! Since it needs to be heavily diluted, I don’t notice much of the scent after mopping. I do wish it had a stronger fragrance, but it gets the job done, so I’m very satisfied!

Works good but doesn’t make the house smell nice
Size: 8 Fl Oz (Pack of 2)
This works good in our robot vac/mop however it doesn’t make the house smell good when the house is mopped, just when you put it in the water tank. The floors are clean and that’s all I really care about but would it be nice to smell freshly mopped, yes.
