Advice needed please

#1
First off hi new to this site and plastering world just fully qaulified and started a small private job rendering

Scratch coat 4:1 rendering sand cement used waterproofer and mortisizer
Apllied and scratched
Was good
Set beads great
Left for 10 sunny days

Went back today and well started top coat

Applied 5:1 rendering sand cement
Waterproofer and mortisizer
Leveled off left to dry up and floated
Now this is where it all went wrong for some reason when floating it seemed to be very grainy and had alot of holes and well just looked absoutly s**t excuse my french i had to leave it and hopefully try fix it on monday but need advise and help would you say i never put my top coat on thick enough for this to happen or is it my mix maybe i should have used a rendering soft sand mix perhaps to try reduce the stones in the rendering sand

Pictures uplaoded show how bad it is and i want to make sure it looks good

My solutions to thinking would be maybe to score the top coat hit it with a slurry mix then go over again with a top coat of render sand and soft sand mix would this work

Do you know what if your charging a paying customer I don't even want to comment...

No disrespect but they should not be paying you for your services your trying to run before you can walk and practicing unfairly on people's homes!

5 to 1 is a bit weak for outside ,it looks like it dried too fast ,in my experience too much mortisizer makes it to dusty and dry ,you say u used both waterproofer and mortisizer not sure which brand u used but most waterproofers have mortisizer in them also u never mentioned using lime which I would have ,up on that roof I would have 3 to 1 scratch and 4 to 1 top coat with lime and no mortisizer just waterproofer also did u wet the scratch enough before u started to kill the suction

Oh dear me, God bless you for trying but I really hope you did not take any money for that. Basically you have done quite a few things incorrectly and the sand you have used has been shite
