Rated 1 out of 5 by from Read the reviews Thought I would try this product after reading a view reviews, however I have now read the reviews on page 5 and agree it's total rubbish. Had to spend an hour scraping it off my newish tongue and groove chipboard floor with a 3 foot plasterers bevel. Doesn't level at all left all dimples arter using a Spikedroller. Not happy.

Rated 3 out of 5 by from Seal, seal, seal We’ve used this stuff three times. The first was a small room, less than 4 m2, and quite successful. The second was 6 m2. We did this from memory – not a good idea when you’re in your seventies – and forgot to seal beforehand. Expensive mistake. For the third – another go at the same room – we sealed with two coats of PVA:water at 1:4. Went well. From this experience, we reckon it is critical to seal thoroughly. If you don’t, the floor will suck out the water –differentially from bucket to bucket - and flow stops quickly or immediately. Don’t rely on any old sealer that might already seem to be on the floor; it’s probably worn or split. If you do seal very well, it should not be necessary to exceed the maximum water content recommended on the packet, as suggested in some reviews. If you do add extra water, the sand content seems more likely to sink out of suspension, causing separation and reducing flow. But - our jury's out on this. Nor should it be necessary to use trowel, roller etc. Another suggestion is to respect the flow boundary of each bucket and make the next one meet it fairly gently, i.e. don’t try to push back the first bucket too much with the second in an effort to increase overall thickness. Obviously, for larger rooms, you can’t expect the stuff to level right across; you’ll probably have to accept gentle gradients between sub-areas. Finally, the more mix you can get ready before you pour anything, the better, so that you can pour lots at the same time. This might mean investing in several large plasterer’s buckets.

Can I pour this over a fresh dry layer of No Nonsense levelling screed

I need a 2mm layer of this product to raise the level of the screed (same brand) I poured today. Can I pour this one over the top? Do I need to prime first?
Asked by: HHA21
Hello, Thank you for your enquiry. You will need to allow you floor screed to cure for at least a week, because you may trap moisture under the floor and cause the levelling screed to move and crack. Thank you for using Q&A..

can this be laid over black jack dpm

Also, can this be used over existing concrete subfloor which has been sealed with Black Jack DPM - the membrane has failed in some places but removing all trace of it will be impossible. Intend to screed then lay new plastic DPM.
Asked by: Wanblue
Hello Wanblue, Yes, this can be used to overcoat the previous surface in preparation for a new DPM being laid. Thank you for using Q&A
