[Cob] protecting a cob bench/ Tadelakt lime palsterCharmaine Taylor dirtcheapbuilderbooks at gmail.com

a lime plaster will protect anything is covers if done thick enough- in layers, ,,, but the problem is now the cob bench looks like something else. and if the seat is flattish water will hold and soak in, it WILL EVAPORATE LATER, BUT THIS IS A CASE FOR DOING A TADELAKT MOROCCAN LIME PLASTER. OPPS CAPPS. sorry This lime plaster method has a black Olive oil soap in it, uses no sand, and the lime and soap are polished in thin layers right on the clay/cob. In the Middle east there are bathtubs, sinks, shower stalls and floors that are water proof after the lime soap coating. it it a lot of work to hand polish, there is no work around to this labor. the best lime for this is the stuff mined in the Middle East, but you can also try a hydrated lime and oil soap mix.. there are many YouTube fake Tadelakt products I have seen, where you do little polishing, so it is a commercial product. it may seal up your bench, but not sure that is a good thing if there are additives in the product. Michel Smith used this method on one side of his cob home- the finish is like marble, impenetrable... but he did say it was a ton of 'arm work' to do it. I mentioned on another list there is a new book coming out in 09 that is a German translated Tadelakt book...it has formulas, and how to, and images of completed amazingly smooth hard walls. the shower stalls and the curvy designs will be loved by any cobber!
