Is my contractor using Redgard correctly?


On April 7th, cement board was installed after we passed framing, plumbing, and electric inspections.

On April 9th, Redgard was applied to the cement board.

Today, April 10th, they applied thinset to the gaps between the cement board and started tiling.

The tiler assures me that the small gaps in the cement board that was covered with thinset do not need another coat of Redgard. They will apply more Redgard to the areas where the gaps are bigger. They also applied silicone to the corners where the tiles meet.

Is this being done correctly?

Not the order in which I did it.

1. Tile board to walls
2. FibaTape mesh the seems, corners and cover with thinset along with screw holes.
3. Redguard 2-3 coats.
4. Tile

If you use tape and thinset, there are no gaps to continue to re-cover with a membrane.

It will probably work, but you just have to hope the gaps are actually covered.

Is there a shower involved?
That picture on the right just makes 0 since to me.
Looks like a drunken sailor applied the Red Guard.
Should have been applied on the whole wall not just dabs where it made no since to apply it.

Shower is on the left. Shampoo niche is on the right. The RedGard was applied before the put thinset to fill the gaps.

RedGard was applied to the cement board. And then, they applied thin set to the gaps and seams. They did not re-apply RedGard to the thin set covering the seams and gaps. Only one coat of RedGard was applied.

Now I'm confused,
You posted one picture with it smeared on the wall Just in patches, last picture show sit all over the walls.
Go on there web site to see the suggested application.
One coat and applying the tape and thin set after the Red Guard is the wrong way.
May still workout, some people apply no water proofing to cheap out.

Here's how I did my shower:

1. Installed cement boards.
2. Applied silicone around the base of the boards and around the top of the boards where they meet the ceiling.
3. Taped seams and corners using Laticrete's cloth tape and Hydro Barrier waterproof membrane.
4. Waterproofed all screw holes.
5. Then applied waterproof membrane to the entire wall.
6. Tiled (contractor)
7. Applied silicone to the corners and again around the base of the walls where they meet the shower pan.

I think what the OP is saying is that they put Red Guard all over walls, then went over it with thinset (which is why the first picture looks like only a little redguard, when it's actually just a lot of thinset.).
