If you are looking for a high-quality stone sealer that provides long-lasting protection to your concrete and stone surfaces, look no further than 40SK Densifying Sealer and Water Repellent. This product is perfect for concrete sealing, concrete densifying, and concrete waterproofing needs, while also providing a beautiful natural finish that enhances the color of the surface it is applied to.


At its core, 40SK Densifying Sealer is a concrete densifier that penetrates deeply into the concrete or stone surface, filling any pores or capillaries. This makes the surface more dense and resistant to water, stains, and other common problems. Additionally, it provides a protective barrier that prevents water from penetrating the surface, while also allowing the surface to breathe and release any moisture that may be trapped inside.


Another great feature of 40SK Densifying Sealer is its long-lasting protection. Unlike many other stone sealers that need to be reapplied every year or two, this product provides a lifetime of sealing and densifying capabilities. This means you can enjoy peace of mind knowing that your concrete or stone surfaces are protected for the life of the product, and guaranteed up to 25 years when installed by an accredited applicator.


Overall, if you want a waterproof and long-lasting solution for your concrete sealing, concrete densifying, and concrete waterproofing needs, 40SK Densifying Sealer and Water Repellent is the perfect choice. So why wait? Give your surfaces the protection they need today!


STAIN-PROOF® 40SK Consolidator (densifier) & Water Repellent is a saturating, invisible and breathable sealer that protects porous tile, natural stone, brick, terracotta, paving and grout from damage caused by water and salts, plus helps to protect stone from harsh annual cleaning chemicals used by most pressure washing companies. Treated indoor and outdoor surfaces become easier to clean, maintain and keep looking newer for longer. 40SK Consolidator & Water Repellent provides lasting protection for engineered concrete, roof tiles, cast stone, paving, sandstone, limestone, brick and grout.


40SK Densifying Sealer - The Ultimate Solution for Concrete and Stone Sealing and Waterproofing

40SK Consolidator & Water Repellent is suitable for a wide variety of applications, including building facades, floors, walls, swimming pool surrounds, patios, garages, kitchens and public and private entertaining areas.

Why 40SK?

  • Deep saturating, permanent water repellent, plus consolidation (densification) of softer materials, like limestone and concrete. Use 40SK for premium protection against problems caused by water and water borne salts, including: efflorescence, salt spalling, freeze-thaw spalling.
  • Popular for sealing sandstone, limestone, travertine, concrete dry-stamped pavers and composite stone pavers around salt water swimming pools, or properties near to the ocean, and properties where salt / anti icing treatments are used during the winter.
  • Retains natural surface colour and finish (completely invisible to the human eye)
  • Keeps surfaces looking new for longer, makes cleaning easier, and dries quickly even after heavy rain, due to the sealer preventing saturation of the stone or concrete.
  • Breathable: water vapour escapes freely, avoiding moisture build-up inside the material which can also cause a freeze thaw damage of the stone during the cold Canadian winter months.
  • Designed for indoor and outdoor surfaces, proper respiratory protection equipment should be used indoors.

Hard to Beat for the Price
Size: 10 Wide, Color: Tan Leather Burnished
I purchased these for a business trip to Italy and wore them daily for the two weeks that I was there, during which I walked extensively. For me, there was a break-in period of a few days; before it loosens up, it will bite your heel, so I recommend wearing bandages or heel pads initially. Following the break-in, it's a very comfortable shoe and has served me well. I purchased a wide, and for this shoe, I found the width agreeable; in my experience, Cole Haan wide widths tend to be hit or miss (i.e., a wide is sometimes not all that wide). In terms of durability, I would not expect these to remain in good condition for more than a year if you wear them daily. The leather is not of high quality, but it's acceptable for the price. Expect them to crease very quickly if not using shoe trees. That doesn't bother me, but I know some find it objectionable. All in all, I like them and would buy them again. It's a comfortable alternative to traditional dress shoes for the office and works equally well for casual wear. Most higher quality options cost at least two or three times as much, and many are unavailable in a wide.

My favorite shoes
Size: 14 Wide, Color: White Leather
I’ve probably purchased like 40 pairs of these shoes or more. By far my favorite white sneaker. I have a large foot so the bigger sizes are appreciated. They’re versatile, literally go with anything and they are true to size. At a certain point they start to show wear and you can’t dress them up, but they last as a regular sneaker for a long time afterwards. I try to nab them on sale when they drop to $50-$70, absolute steal at that price point.

Clean Look, Super Comfortable – Instantly a Favorite
Size: 9.5, Color: White Leather
These sneakers are exactly what I was looking for—sleek, minimal, and incredibly comfortable right out of the box. The white leather looks sharp and pairs easily with everything from jeans to chinos, even dressed-down office wear. What surprised me most was the comfort. The sole is lightweight with just the right amount of cushioning, making them perfect for walking around all day. I’ve worn them on long city days and never felt sore or tired. They fit true to size (I’m a 9.5 and they’re spot on), and the quality feels premium. If you're after a versatile white sneaker that balances style and comfort, these are 100% worth it.
