Waterproofing Kits

Tank/10® Liquid Waterproofing Compound tenaciously bonds to a variety of surfaces to form a completely seamless protective shield against moisture penetration. No seams means no vulnerable joints or weak areas. And this easily applied material is low odor and so tightly formed that it’s rated for steam shower applications.

The extra protection provided by our joint reinforcement tape and pre-formed corners provides exceptional seamless waterproof protection, yet keeps the system simple and easy to install—no thinset, no handling big sheets of membrane, and no materials with “pre-stick” adhesive that give you one shot at getting the placement correct. When you’re done installing a TrueDEK® foundation and thoroughly covering the area with an ARC waterproofing kit, you’ll have a seamless, multi-layer line of defense safeguarding your home and your health.

In addition to its outstanding waterproofing performance characteristics, Tank/10 also provides an anti-fracture membrane to help prevent and limit the effects of slight movement differences between tile and the substrate below. The impact on your shower is a reduction in the transfer of movement that can form a crack in grout or tile.

Choose from among three kits, each one designed to meet an installer’s needs. ARC’s Premium Kit includes enough supplies to waterproof a basic alcove shower, plus convenience items to have on hand for the installation. Take away the convenience items and you have the contents of the Standard Kit. And for those who want just enough waterproofing material to cover a TrueDEK foundation only, there’s the Pro Kit—the Pro Kit is the right choice for contractors who want to use a different waterproofing system on the walls or throughout the rest of the bathroom floor.

  • Thick consistency is easy to spread and builds-up quickly
  • Dry time is generally 1 to 2 hours
  • Dark gray color contrasts with tile layout lines for high visibility
  • Faster and easier installations compared to fabric-type waterproofing systems
  • Bonds stubbornly to GRP, tile backer, plywood, drywall, and many other materials
  • Joint tape and corners are thick and tough, yet flexible
  • Ideal waterproofing system for standard showers and steam showers
  • Tank/10 formulated and made in the USA
  • All waterproofing products are available in kits and separately

Premium Waterproofing Kits: Enough waterproofing supplies to complete a basic alcove shower installation (shower foundation and walls), plus convenience items for installing the shower foundation and applying the waterproofing compound. Depending on a project’s complexity and the number of tile backer joints, an installer may need additional supplies.

Standard Waterproofing Kits: Enough waterproofing supplies to complete a typical alcove shower installation (shower foundation and walls). Depending on a project’s complexity and the number of tile backer joints, an installer may need additional supplies. The waterproofing supplies in a Standard Kit are identical to those in a Premium Kit, however, Standard Kits lack the convenience items that a Premium Kit contains.

Pro Waterproofing Kits: Enough waterproofing supplies to complete a basic installation of a TrueDEK shower foundation (foundation coverage only).

All waterproofing supplies contained in the kits are also available as a la carte items.

What’s the purpose of the Pro Kit?

Like the Premium Kit, the Pro Kit was created because contractors wanted it. Some contractors prefer to use a different waterproofing system on shower walls or the bathroom floor outside of the shower area. So the Pro Kit was designed to provide enough waterproofing materials for the shower foundation only, allowing installers to use other products on the surrounding surfaces. It’s up to a contractor to consider compatibility of the different waterproofing products.

Why should I get a Premium Kit?

The Premium Waterproofing Kit includes extra convenience supplies that are needed when installing a TrueDEK shower foundation. While these are ordinary supplies, having them come in a kit has been a great help to many installers who want to avoid the delays and expense of running to a hardware store for them as they get into a project. ARC created the Premium Kit at the request of contractors who told us that they wanted everything they needed for a job to come in one box, and they didn’t want to run to the store because they forgot to get a few screws or a paint brush.

What color is Tank/10?

The dark gray color of Tank/10 makes it visibly easier to spread over shower foundations and tile backer (you can easily see any spots you miss) and the color darkens slightly as the compound dries.

What is the shelf life of Tank/10?

Tank/10 has a 3 year shelf life. A born-on date is printed on a label that is adhered to every bucket, and the date is also written on a label that is stuck to every waterproofing kit box.

What kind of base is used in Tank/10?

Tank/10 is a premium latex based liquid paste compound. It is quite thick and has a very high latex content, which results in a product that has the consistency of pudding and spreads out in a thick layer to create a protective membrane. Tank/10 can be spread with a paint brush, paint roller, or trowel. Cleanup is best done while the material is wet using warm water and a mild soap.
