SUBSTRATES FOR PLASTER FINISHES IN SHOWERS

We get so many requests from contractors and homeowners asking for information on how to do showers these days.  Probably our single-most requested technical info item.  My answer is always a resounding “don’t ask me”.  But seriously, tackling a shower surround is a whole different animal than just putting up a nice finish over drywall, so this is no job for amateurs.

Fortunately there are now full start-to-finish systems available that seem to be working great as a substrate for Tadelakt or even Marmorino Carrara or Intonachino.  Our applicators have had excellent success over the past 4-5 years with the Wedi board system which is a lightweight alternative to cement board and include a special panel fastener that seems much more reliable than simple screws, as well as a paintable urethane caulking system to ensure cracking does not occur at the joints.

During last week’s decorative cement class one of our students gave me a brochure from Schluter, another leader in the wet area substrate industry (thanks Tamara!).  They now have a relatively new system similar to Wedi called Kerdi-board.  And they have seminars around the country for interested contractors.  In our area there is one coming up in Lynwood, WA May 17th, Tacoma on May 18th,  2011 and Portland on May 19th, 2011.  I’ll be at either the Lynwood or Tacoma one for sure.  Here’s a link to the page listing Schluter seminars.

These seminars are free.  So you want to install an incredibly beautiful Tadelakt or other lime-plaster finish in a shower and not sure how to do the substrate?  Maybe quit calling me and go learn how to do it right from a professional. ;-)

    Love the shape of those curved and bullnosed walls. Nice! It must be very difficult to trowel over those rounded edges. We have had a plastered shower for 7 years. I think I have had to clean the walls twice per year and it still looks awesome. I seal my showers with Masco’s cure & seal. It is strong stuff that lasts and lasts. But it’s so toxic when applying.

    Good to see this Aaron. I’d love to hear what materials, if any at all, others are using as a “scratch” coat over the Wedi and Schluter waterproof membranes.

    In my case I ended up using modified thinset as the “scratch” coat, as I was unable to get stucco to adhere to the Schluter Kerdi.

  5. Stucco is a material made of an aggregate, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a coating for walls and ceilings and for decoration as well. Stucco may be used to cover less visually appealing construction materials such as concrete, cinder block, or brick.
