    Do you flooring guys prefer Red Guard or Hydroban to waterproof a shower? Why do you prefer one over the other? Everything I’ve read boils down to a personal preference, or what’s available in your area.

    Also, which substrate do you prefer to use behind that waterproofing agent on the shower walls? I just hope it it isn’t greenboard.

    I’d like to exclude the Schluter-Systems, because of the cost difference.

    Their both outstanding products. I use Hydroban – it’s what I was taught and is locally available

    Durock

    I use Hydroban whenever I use a liquid membrane. The RedGaurd is too thin of a product, meaning it takes several coats to get the minimum thickness required by the manufacturer. You are using a wet film gauge to ensure you are getting enough on the wall? The Hydroban is a thicker product and because of this it feels easier to work with. I also like to use Mapelastic HPG liquid membrane too. It seems to be the thickest product that is available locally. It is thick enough I can flat trowel it on the wall and usually achieve proper thickness of the membrane in one coat.

    You say no to Schluter, because it’s too expensive. Are you looking at just the fabric cost or have you compared start to finish shower prep? I’ve found that if you factor in all of the time for prepping a liquid w/p shower and compare it to a Kerdi prep. I can usually be ready to tile a couple of days earlier with the Kerdi system than with the liquid w/p system.

    For instance, with a 3×4 new construction I can hang the wall board, hang the Kerdi on the walls and pull the mud in one day. Second day I start running tile on the wall using a ledger board. At the end of the day, I Kerdi the shower floor. Third day I finish tiling walls and floor. On the fourth day I grout and collect payment.

    With a liquid membrane, start hanging board from the ceiling down. Leave out bottom row of board in order to apply preslope mortar. Second day install pan liner, remainder of board, and apply first coat of waterproofing. Third day apply second coat of membrane and pull mud floor. Fourth and fifth day run tile. Sixth day grout and collect payment.

    I’m not sure how you price you work, but I do my estimate based on my labor cost for me and my helper, daily operating cost for the business and that evil P word (PROFIT). Of course, YMMV.

    One more thing, for all liquid w/p showers, I use Durock. For my Kerdi Showers, I used drywall per Schlüter’s instructions.

    Thanks for the input guys.

    Gregory,
    I was asking about Red Guard and Hydroban because of the price differences. It’s my understanding that Red Guard is thinner, but complete waterproofing requires 2-3 coats. Hydroban, on the other hand, costs 2-3 times the price of Red Guard, but only requires one application. Also, I omitted Kerdi due material costs only, to do a comparison between liquid membranes. Does Lowe’s sell the Mapelastic HPG you mentioned? The product name sounds familiar, but I may be mistaking it for something else.

    I think Lowe’s only carries Mapei’s AquaDefense, which is a step up over the HPG. Cost is about the same as Red Gaurd in the one gallon containers, at least in my market. If you can find a local Mapei dealer, you should be able to get some.

    Mark,
    Do you have a Menards by you? They have Mapei products locally here. Hydroban does require 2 coats to get the mil thickness. I love laticrete products and like hydroban . The light green color makes it easy to see if you have any voids.

    I just completed a bathroom remodel and opted for the Kerdi — it worked fantastic and this was the first job I have done with it. Amazing stuff. I was originally going to use one of the liquids but after reading other forums and doing some research, it seems like the Kerdi system was the way to go.

    Durock is ok but I’ve had outstanding performance and durability with Hardibacker. I will not use anything else. easy to score, no mess, and it’s lightweight.

    Red guard I feel is better for a solid gel waterproofing. I have done numerous showers and copper pans and I’ve always had great hold with it!

    I use durock , wedi , hardibacker . What ever fits the project budget . Redguard works well just have to watch how your roll application goes on .

    Why I use HYDROBAN. The thickness makes it less goof proof.
    To be sure you have the correct membrane thickness, use a V-notch 1/4 x 3/16 trowel to apply. You want to see those ridges. Let first coat dry and now with flat side of trowel, fill IN those low spots smoothly. There you have the recommended thickness of membrane.
    All this on clean clean smooth, taped/thinset seams (you left required gap? )
    All set.
    THAT is why I prefer HYDROBAN. If you do use. RedGard, first coat mix one part to three water and prime it all with that. The following straight coats triple on pan and seams, one coat. One. direction and next the other, etc.
