Cement rendering for pond

[roughcaster]

Everything I mix when rendering I use a bucket and mix ratio's of sand,cement. lime by the bucket, and the additives, by what they say on the containers...

Roy is spot on with his advice above!!!!
Never guess a mix,, if you "measure " the quantities of, (sand,cement lime, additives, (liquid or powder) etc),, you'll always get a consistent mix, colour, etc.

I was shovelling the sand out of the bulk bag into the buckets, and sometimes it took 4 shovel fulls and sometimes 5 to fill the bucket.It just goes to show you can never be consistent with shovelling straight into the mixer

Thanks Guys.

As predicted, it rained over the weekend I had planned to do it.

I got a Sunday afternoon to do it the next weekend though. Did the 1 coat of slurry and allowed to dry. Then another coat of slurry and a 3:1 render with fibre glass. I found the 2nd coat of slurry dried too quick, so I just painted a couple of feet and then applied the render directly onto the wet slurry. Time will tell; I have to wait 3 weeks apparently before I can apply my waterproofing.

Now I just have to apply a screed to the floor. Any tips? What's the difference between a screed and a topping?

Thanks
