Dealing with threshold after self levelling

[randytusk]

Hi folks.

I ve just finished self levelling the wonky garage floor - up to 30mm of variance across the whole slab. It s quite a thick pour resulting in a fairly substantial 20mm threshold

I ve used industrial grade screed so I m going to seal and leave as a finished floor.

Any suggestions for the threshold?

My thoughts are either a tile in ramp or would it be advisable to create a cement mortar ramp with SBR? If m wondering if a feathered edge would hold up to wheel traffic?

Straight forward sand cement mix with fibreglass strands and a stiff mix , sbr the existing surfaces and splash a bit in the mix and trowel to suit your levels .

^ Do that, though instead of a normal mortar mix, Google ‘granolithic mortar’, 3 grano dust, 1 cement and a touch of building sand: it will give you a very hard wearing, fine concrete. I’d also grind away what looks to be black garage floor paint where the ramp is going before priming with SBR. For a belt and braces job, grind/chisel out some of the existing concrete at the leading edge of the ramp so you have a bit more thickness there.

That black paint is actually the bedding for the screed we poured - its epoxy-fibreglass 350gsm-epoxy and quart 1.2 blinding on top

Hmmm I have bucket of leftover quart sand - that would probably make a decent cement aggregate would it not?

^ Possibly, not sure, whereas grano mortar is known for its durability.

Which screed did you use? I’ve got a similar wonky floor and will need to level it later this year.

Thanks
