[WelshSkipper]

Hi i've just finished rendering the outside of my garage after following lots of advice from this forum, using an SBR Slurry then a scratch and top coat, the SBR was quite awkward to work with and render over before it dries though, and expensive to do a 12mx5m garage. i would like to just put a skim coat over the internal walls of the garage just for cosmetics, was gonna try either rendagrip or febond blue grit.. Does blue grit work for internal render? It's painted smooth brick at the moment hence the need for a mechanical key, any advice much appreciated thanks
