A slight drop would be as near as plumb on an individual board basis. You do you, but I ain't no mug paying £70 for posh gaffa tape to solve a problem that doesn't exist

so why do you paint jacks black on ground contact pressure treated timber for then?? is it too help stop the rot of the timber for longer life?? because thats what butyl joist tape is doing for the deck timbers, but hey...A slight drop would be as near as plumb on an individual board basis.

That's timber to ground contact, not timber to timber contact. All you are doing is creating a way for water to pool. It is snake oil made for TikTok builders because it looks fancy.

To add to this. Isn't the point of the tape, to stop the rain sitting on the top of the joists and penetrating through. No one is talking about wrapping the whole thing - just the top side to allow run off, in addition to a standard fall.

I believe there is no such thing as "upside down" with groove/flat edges as I recall.
Anyways I'm not installing decking (yet! / this project..... Later for the garden room next year.... But I'll go composite for sure)
Moved over 4 tonnes of grit (/sharp) sand and cement ( 171bags) into position ready for mixing. I'll be doing a 5:1 mix with a little plasticiser in it.
Ive bought some prebagged larson primer rather than mixing my own primer with SBR.

Must have taken some hauling…..
Nah it was grooves down. Then everyone started installing them grooves up for looks.
Put some of the sandstone in.
Ive marked out 1:60 points on all my levels, this is about 1.5 days so it is taking a while! Hopefully I speed up as a lot to do. Main one was getting 1st right as it sets up the rest..

How much mix are you requiring per slab?
Think the above that I've done I've used about 10 bags (25kg) of sand and 2 cement.
So I guess the short answer is lots!

Looks good.
Looking good.
At some point in the near future I expect SWMBO to order me to relay the patio here which is somewhere in the region of 100sqm+, down the sides of the house and to the rear.
I do wonder if a grabbo style lifter makes positioning large slabs any easier? Or if offering up once on the bed of mortar is sufficient.

If you're implying the correct orientation is grooves down then thats nonsense. The grooves were originally designed to go up, but now they often come with ribbed one side and grooves the other to give a choice. The idea the grooves are for airflow is just internet misinformation, no doubt started by some DIY youtuber and regurgitated online for years.

Nah originally it was grooves down, it came from the US were smooth decking is king and the underside is ribbed for airflow. People in the UK started laying it grooves up in the false belief it improved grip and for aesthetics. These days most of the cheap deck board here is only finished on the grooved side as apparently this is what we prefer in the UK.
The debate is fierce, its not just youtubers saying its grooves down

I love it how people put down diy youtubers, tiktokers etc etc while posting DIY advice on an IT forum…..
I don't think grabbos would work on these riven sandstone. They'd be fine /good for "flat" porcelain. Tbh you get used to it. 100 sqm will be horrible on your own!
