rendered a wall with blue 10mm fibreglass mesh embedded in the render coat using a 4-1 mix with waterproofer,the cement i used was quinns which i have never used before,but anyway 2weeks later hosed wall down top coated with 4-1 and 1/4 lime using same cement,but as laying on it was bubbling as if there was air pockets all over the wall i got away with it as i was dashing but fining down the plinth was a nightmare as it pulling away from the wall when floating,just wondering was it the cement,the mesh etc,but i did notice when hosing the wall down there was small soapy bubbles appearing here and there which i havent experienced before, i know its been warm but the dashing was done when it was overcast with drizzle,thanks
