It makes sense on a job where you are only doing the bathroom and have nothing else to work on, but in a production environment isn't spraying or rolling on a liquid membrane less costly and less labour?

I went full circle with showers when I gave a ****. Ended with dry pre slope drypack full liquid.

The kerdi board isnt strong enough between 16oc imo. I started run 1/2 ply first and full gluing before I woke up and said f that...

I used Red Guard once, 2 days with prep and dry time.

Why did it take so long? We can rock and waterproof most showers in a day. Recoat as soon as it's dark (usually by the time I am done with the first coat it's dry to recoat. After the second coat 30-50 minutes and you are good to tile over.

We just tiled a small 5x6 bathroom, floor and shower in two days.

I had to flood test the area, according to the instructions it must be fully cured to flood test. Coat one went on day one, coat 2 went on early day two. Wasn't cured until early evening of day two.

I do Redgard as well in a day no problems...a fan certainly speeds up curing but it dries pretty fast, especially the first coat.

Much easier and less costly than the competition. Not that there's anything wrong with Schluter Kerdi...except it costs like festool :blink:

Yeah, I can't compete on price. Although there are other flooring installers who do showers locally who use kerdi also.

Its pretty much gonna be at least $1500 labor and material for me to get a basic shower waterproofed with a niche and corner seat.

You red guarded the shower pan instead of doing a traditional pan liner? Red guard over the pitched mud floor?

Those of you doing liquid are you not taping and mudding the seams? What are you using behind the liquid? CBU always seems very labor intensive to install.

No need to mud. Fibafuse and AD.
