Cold Weather Alert

This product may not perform properly if applied below the required temperature. Please check installation instructions on our website. Because this is a water-based product, it may freeze during shipping. For that reason we will not ship over a weekend if temperatures dip below 32 degrees F. If you want us to ship anyway, it will be at your own risk. Please call to arrange with a GBS eco-advisor. 888.727.2101

GBS Penetrating Sealer is a waterborne polyester polymer and polyurethane that works best on concrete, brick, stucco and masonry. It waterproofs and preserves with 3-5 coats, plus it comes with a 15-year waterproofing warranty. Unlike topical sealers that sit on the surface and rub off with wear and tear, GBS Penetrating Sealer protects from inside the material where it can't wear away. In other words, this sealer actually becomes part of the substrate.

This sealer penetrates two to four inches deep, filling molecular voids to completely solidify the entire structure. When it dries, it becomes part of the structure creating a solid matrix. This means there's no room left for water to infiltrate and leak through. In addition, the substrate becomes stronger and lasts longer.

Dry time for indoors is apx. five days; outdoors 2-4 days depending upon temp and humidity. Allow 48 hours before walking on. Avoid using it before rain.

GBS Penetrating Sealer is solvent-free, odorless, non-flammable, non-caustic, and almost no VOC (5.9 g/l). Use it on basement walls and floors, retaining walls, pool surrounds, brick veneer walls, chimneys, fireplaces, concrete or limestone pavers, driveways, sidewalks, patios, warehouse floors, and historical renovations.

Quality Control Test results: GBS Penetrating Concrete Sealer has passed 9 independently performed quality tests per the HRP specifications. These tests include:

  • ASTM 413 - “Water Absorption of Chemical Resistant Concrete/Masonry”
  • ASTM C140 - “Masonry Absorption Test for Light Weight Block”. ASTM requires that water absorption cannot exceed 1% after 2 days of immersion.
  • ASTM 123D - “Penetration Test for Nuclear Power Plant, 8000 psi Concrete Pour”
  • Blue Dye Test - “Blue Dye Absorption Test”
  • ASTM 642-82 - “Masonry Absorption Test for Brick”
  • ASTM C672 - “Scaling Resistance”
  • AS 1012.21-1999 - "Water Absorption of Hardened Concrete"
  • NCHRP 244 – Cube Test – “Accelerated Weathering Test”
  • NCHRP 244 – Southern Exposure – “Chloride Ion Penetration Test”
  • NOTE 1: GBS Penetrating Sealer should NOT be used in areas constantly under water such as cisterns. Also, any areas that have been power troweled, especially in basements, need to be acid etched or mechanically ground before application in order to open the pores. This product should not be used on stamped concrete.

    NOTE 2: Do not use this product in working fireplaces as it is not suited to that kind of heat (may bubble and melt).

    NOTE 3: If you plan on applying ceramic or porcelain tile to the surface at some point in the future, do not use this product. It will seal the concrete so well that the thinset will not adhere to the surface—unless, of course, it is etched or ground.

    NOTE 4: This product will only perform well if applied correctly. Be sure to read and follow the application instructions.For proper adhesion, the surface must be:

    1. Porous
    2. Clean
    3. Free of any other sealers, coatings, stamped concrete release agents
    4. Neutral pH — between seven and nine
    5. Dry

    Please see the application instructions for details on each of the above steps.

    NOTE 5: You can paint over this product with a 100% acrylic concrete floor paint. We recommend AFM SafeCoat Concrete Floor Paint.

    A similar product, GBS Penetrating Gloss Sealer, provides a low-gloss finish.

High Quality and Surprisingly Powerful
Color: Absolute Black, Size: Z1 Motor + Batteries
The Pros: Unexpected Power: I usually know exactly what to expect with the products I order, but this unit really blew me away. It is surprisingly powerful and handles everything much better than I anticipated. Premium Batteries Included: It was a great surprise to find that it came with Duracell batteries. Seeing a name-brand battery included really speaks to the overall quality of the product and shows they aren't cutting corners. Solid Build: From the moment I set it up, the unit felt sturdy and well-constructed. It is rare to be this genuinely pleased with a purchase right out of the box. The Cons: Operating Noise: Because the motor is so powerful, it does produce a bit more noise than some weaker units. It isn't a dealbreaker, but it is noticeable during extended use. Bottom Line: This is a high-quality product that exceeded my expectations in both performance and presentation. The fact that it comes ready to go with reliable batteries is a huge plus. I am very pleased with this purchase.

Pleasantly surprised.
Color: Absolute Black, Size: Z1 Motor + Batteries
Honestly, I bought this because it was on sale and I needed to add something to my cart to get one day free shipping. I had zero expectations and thought I'd use it when I travel and won't have access to my espresso machine but I'm blown away by what it can accomplish in its small form factor. It took 30s to froth the milk and it was well-incorporated into the milk, not with just foam on top and milk at the bottom. I could have the frothed milk all day. It's easier to clean than the steam wand and it does plant-based milk cold foam!! It blows the Ikea one out of the water for about the same price point. Glad I stumbled into it!

Works great for daily use, just be prepared to replace batteries
Color: Absolute Black, Size: Z1 Motor + Batteries
I use this every morning to mix protein powder into my coffee, and it works well. It is quick, easy to use, and does a great job blending everything smoothly without clumps. For the price, it’s a great little tool and has definitely been worth it for daily use. The only downside is that I do have to replace the batteries fairly often, about every 3–4 weeks with regular use. Overall, it’s a very convenient and effective frother, especially for the cost. I would recommend it, just keep extra batteries on hand if you plan to use it daily.
