Am I using hardwall correctly?

[Hairybear]

Guys, had a job to float and finish a couple of small walls the other day. I used hardwall as was on 100hr old brick.
Now, I lay hardwall in two coats, but I don't scratch the first, I just wait for it to pick up a bit they lay and rule off the second coat, never had a problem. Was a guy tiling in the bathroom who I got chatting to whilst waiting for first coat to pick up, he asked why I didn't scratch it as he would have ( said he was a spread years ago till his shoulder gave in).

So, scratch or not to scratch?

Personally never scratch mate i just do as you are n im on site at the moment with about 10 lads and were all floating and setting no one gets the scratch comb out just a devil key after ruled off ready for skim coat

hardwall in one coat unless its thick , if its thick it will slump, do use two coats then but don't let it set completely before 2nd coat , gypsum plasters don't bond well on top of set plaster , anything over 15mm I use 2 coats, then devil float and prep for skim, the answer to your question if you leave first coat to set then a scratch required if its still soft and green no scratch required because they will set together

If it's an old wall I would have two-coated and scratched the first coat.

if i do hard wall in 2 coats i always scratch the first coat, only a quick scratch,,takes no time at all

I was taught to scratch but never do between coats

[JamieMac]

If its old walls and you have to make flush with existing then yes

 

[JamieMac]

Hardwall can go on at a good thickness before it starts to slide unlike sc

Mix it and throw it on.simple.And tell the tiler to mind his own ******* business.

I scratch everything makes me feel like I'm doing it proper

On new blockwork there's no need to scratch.

always scratch between coats. its what i was taught and takes seconds.

id rather scratch it to cover my own back. if that key fails first thing the customer or any person inspecting will say is where is the scratch coat

There would be if you needed to build it out to 20-30mm because the brickie was sh*t

 

[Hairybear]

Yep, fair point.
