Should there be surface water on newly laid screed?
I’m Andy Parkin Managing Director of the Multi-Award Winning Speed Screed. Thank you very much for your question, Dee.
Your question is:
“Should there be surface water on newly laid screed“
Watch Andy’s video to find out his answer:
I will take that it is a liquid screed that you have, and what you are seeing is the bleed water that comes to the surface very quickly after the screen has been laid.
It is the bleed water that comes to the surface and then within around 12 hours, that bleed water is sucked back into the screed.
Perhaps if the screed is particularly heavily watered before it is laid, the water may take longer to disappear.
There may also be segregation if the screed is not thoroughly mixed through the truck mixer drum during delivery.
There may have been some settlement in there, so you can see a little bit more water. But I think what you are actually seeing is that initial water that comes to the surface just after the screed has been laid and then generally is sucked back in.
The important thing is not to try and dry that water off because that water is essential for the screed. You don’t want the screed to prematurely dry because you will end up with problems and a weak friable surface.
You need that moisture in the screed.
You regularly see it in liquid screeds, and it is nothing to nothing to worry about.
So thank you for your question, Dee.
