Thin set mortar is suggested for most applications. Ensure that the substrate is clean, even, and load bearing. The thinset mortar must penetrate and engage the fleece.

Yes it can. We also suggest using thin set mortar to adhere The Shield to your substrate.

The Shield can be applied over a number of substrates like plywood, gypsum board, or concrete backer. It can also be applied directly to drywall.

Both The Shield and Strong Strip are flexible. When bent, Strong Strip holds its shape so you can create a corner.

Yes! Our products can be used anywhere in the home where you wish to tile, but are concerned about water penetrating the tile.

Shameless plug – because or product is 2x wider than anything else out there, you don’t have to seam The Shield as often as you do with other waterproofing membranes. If you do have to seam, we highly recommend using Strong Strip. After using Thin Set Mortar to adhere two sheets of The Shield side by side, simply place Strong Strip over the seam and use Thin Set Mortar to adhere.

We recommend Thinset Mortar.

The Shield and Strong Strip can face either way.

Introvert? Misanthrope? Hermit? Have no fear – installing The Shield is a one-person job. The Shield is firmer than most other products, meaning it doesn’t flop around while you adhere it to the substrate.

No, both are for indoor applications only.

No, masonry block is not a suitable substrate for The Shield and Strong Strip.

Yes! Email your requested roll length to hello@waterproofwarrior.com and we’ll get back to you in 24 hours. We sell rolls up to 200FT long.

Unless directed otherwise by the instructions on your unmodified thinset mortar, The Shield will be set and ready to be tiled over after 24 hours.

Unmodified thinset mortar tends to be best. It dries faster and in our opinion creates a stronger bond between The Shield and the substrate!

Yes.

Yes – both can be installed in any direction.

You should install The Shield beginning from the bottom and working your way up. For full instructions, check out the Super Clear Instruction Sheet most relevant to your project.

According to the Tile Council of North America (yes – that is a real council) there are several key differences:

Unmodified thinset also goes by the name of 'dry-set mortar'; it is pure Portland cement mixed with sand. Think of it as the ‘au natural’ version of thinset mortar. The additive-free, Non-GMO, organic smoothie your cross-fit loving coworker drinks.

If unmodified thinset is the organic smoothie, Modified thinset is the McDonalds Chocolate Milkshake. Although it does contain some Portland Cement and sand, there are a lot of latex/polymer additives mixed in there. These additives can be helpful in adhereing certain tiles, but we believe unmodified thinset works best when bonding Waterproof Warrior to our selection of substrate.

Though we are by no means cross-fit enthusiasts, we do recommend that you use Unmodified Thinset to adhere The Shield and Strong Strip to your appropriate substrate.

We highly recommend a 1/4” x 3/16”  V-notched trowel.
