Hello all.
Some advice please.
This is my first big render job, a semi detached property and I’m on my own on this one. Spent the last two days solid hacking off the old render and bagging up... it has been relentless It’s gonna be a sand cement and hydrated lime mix on the walls.
1) The Scratch coat I’m gonna do is 4 sand 1 cement 1 lime with waterproofer and top coat 5 sand 1 cement 1 lime with waterproofer Is that right ??. I read many variations on this.
2) some parts are fairly new render on thermalite so not hacking off as I’ll end up building new porch !. What is the stuff you roll or paint on and leave 24 hours for a good key for this please.
Lastly 3) as it’s warm it ain’t ideal but the job has to be done. I was gonna wet the walls and then put scratch coat on... wet again before leaving then wet again before putting top coat on.
Would this be ok or any other suggestions please.
I’ll put some pics up tomorrow.
Thanks in advance
