I have done a job today putting a scratch coat onto the side of my house. Its red brick. I used a 4:1:1 mixture using hydrated lime. I also put waterproofer into the mixture.
As I was applying the mix I found it was setting extremely fast. I couldn't even scratch into it as it was just going rock hard. I had prepped the wall by brushing down and filling any hollow points.
Should I have simply just soaked the wall before applying the render mix or should I have done something else??
Will it still be ok to put the top coat on once dry or should I tear it off and start again? Urgent help needed!
Thanks,
Dave
