My 1930's pebbledashed stack is worn out, it's all solid but the stones are all off and the surface looks worn out. I was hoping to mix up a cement SBR slurry and paint this on, then in a weeks time bung on a coat of weathershield. I'm not looking to do a perfect repair job, but if this gives me another 10 years that'll do for me!..............whatd'ya think?
