Slate company are very sorry, and grateful I'm prepared to keep the slate they've sent. They're cutting the small bit and will send it asap
I decided I may as well lay the bits I've got today since the weather is rather pleasant, if a little warm for laying black slate - it got rather hot in the sun
First job was to cut the tiles to size - I had decided on a last minute whim to make the front strips of slate wider than they needed to be and cut the tiles back down to give the thinner strip a larger bed, I was worried them coming loose over time or causing a trip hazard. I found out my old cheapo electric tile cutter had a deep enough cutting depth to whiz the 15mm tiles through which was handy! Here they are all measured, cut to size and layed out...
I took around 20mm off the tiles so its clear from this view that there wouldn't have been a lot of the front strip to bed down otherwise - glad I made that decision when I ordered them
Next job was to mix up some SBR slurry as a bonding layer - slate is non-porous and doesnt like sticking to mortar, as I discovered when a few of the tiles I laid a few weeks ago started moving
I added SBR to cement in a ratio of about 1:2 and mixed it in to a thick brushable liquid slop 😄 Great fun, but you have to be careful with this stuff as it sticks like the proverbial
I wore gloves and set out the slate before I started so I didnt have to touch it with potentially messy hands once I'd started applying it. It also goes off super quick, you've got about 10-15 minutes before it's gone off so I had to mix 3 loads in the end to get it all done
Here are the slabs with the bases coated...
I also did the wall capping slate pieces at the same time...
With that done I whipped the mixer out and made up some mortar, also adding the black pigment I'd experimented with before to try and achieve a dark grey mortar. We'll see how succesfull that's been when it has finished curing in a few days
The slabs and wall strips went down easily enough although I took my time getting it right. Still needs a wash down once the mortar has had a few more hours to go off but looking pretty good I think 😊
I had enough mortar left to cap the wall too 😊
It's nice to be putting finishing touches to some areas now
