Powerfloat Finish

[LA3222]

I got mine as individual cans from screwfix too....cost me a fortune. Annoying as I pay £48 for 12 cans of normal soudal on Amazon.

Thanks Peter but unfortunately different stuff. This is gap fuller which seems so be high expansion. It seems to be hard to find a trade box of low expansion foam.

I find the illbruck products very good and have a good range of products!

Concrete will push water

get a wet vacuum cleaner, pump in concrete to the to the edge beam first and it will push the water around, suck out from last corner.

Scared to death of putting it in the ring beam first as per the other horror story where it all floated up! but a good method nontheless.

You don’t put it in, in one constant area, you need to move the pump hose at a good walking pace, placing the heavy concrete on all the areas. 

 

So walk all around the ring beam filling up 100mm splash a barrow full on all flat sheets to keep them weighted down, you should go through the first truck of concrete in under half an hour. 

 

If you are still unhappy just walk haphazardly around giving everything a 50mm covering. 

 

Or why are you not putting another thin sheet of polythene down like you would for flowing screed. 

For £150 of polythene I think it’s a no brainier.

Power floating even dead smooth won't entirely prevent dust coming off it...and dead smooth will make it harder to use a penetrating sealer (impossible if its also waterproof concrete), and a topical sealer will struggle to bond well....you'll need a specialist powerfloat sealer like Watco (https://www.watco.co.uk/products/watco-powerfloat-sealer).

Hi we are planning to have a power floated slab as our finished floor surface. I was thinking of applying Sikafloor ProSeal W - https://www.rawlinspaints.com/home/floor-paints/floor-sealers/1542-sikafloor-proseal-w.html?gclid=CjwKCAiAmuKbBhA2EiwAxQnt72lVa5Y-KR9dS83fdH9pL4WPUkN7B6KcZVjnsokdhLAhIF5tM2oVfxoCrF4QAvD_BwE 

- after the powerfloat. How does the Sika product compare to this Watco sealer? thanks
