Hi all.
I'm a plasterer by trade and lately have tryed some small rendering jobs
3 fireplaces ready for wood burners and a small porch.
All done 5:1:1 scratch coat and 6:1:1 top coat. Prob between 7 and 9mm thick for each coat.
Finish up the jobs and they look great and I'm very happy with them but pop back the following week with a invoice to always find hairline cracks. It's never sounds blow or hollow. they just appear to be on the very top surface.
What am I doing wrong?
Thanks.
Ian
