Smooth render with silver sand

[Deleted member 31062]

Hi people

The builder who is incharge of the job as requested a smooth finish over brick.. He's got snowcrete with silver sand for top coat finish.. I won't have went down this route myself but he wants it. What's the best ratio for this? 5 sand 1 snowcrete an 1 lime? As heard the line helps it bind? With free flow or plastizier. I've roughcasted with it but never floated up with it. Any tips or should I not do it ha! Thanks

Best ratio is to get back in the van fire it up and tool it down the road !!

What's your background like- strength? Are you aware that snowcrete has stronger final finish than portland? Silver sand and builders are too fine for render, at least for me.

It's on brick. Yeah I read this ..your ment to make your mix higher for both coats. Really can't be bothered with a nightmare of a job. Building sand goes white anyway with snowcrete.. Silver sands s**t to work with.

I've used builders sand a lot but it's getting harder to get good stuff nowadays.. Seems to be very gritty. Few years back it was great to float up.

Here is the catch - silver sand is the cleanest and snowcrete is the strongest. You can make the math .

I know.. Other guys say it's a dream.. Last time I used to wet dash.. It was a mare. But never floated.
