so were still in the same ballpark then?
cement based products can to an extent be made flexible with the addition of not water, but a highly polymer based additive...
and silicon based renders dont suffer from the same shrinkage problems as cement based products but its not something you can knock up yourself, hence the prebagged thing...
just trying to figure out the basics...
all we are basically talking about is adding flexiblility to a cement based product OR using a completely different silicon based (using polymers as a binder? but hang on, isnt 'silicon' basically sand) render / basecoat...
sh't im starting to lose it... too much beer... lets make this a long term thing?
