vfrdave Posted September 29, 2019 Share Posted September 29, 2019 I have cemfloor floor screed with ufh, it doesn't appear to give off much dust. We are hoping to move in shortly with lots of uncovered floor and I don't want extra dust. What can I seal the floor with that won't be detrimental to future tiling or wooden flooring being laid? I have been told to avoid the traditional PVA as it will crack and peel off with ufh, not sure if this is true. Thanks in advance, can't actually believe I have just typed the words "move in shortly" Link to comment Share on other sites More sharing options...
Onoff Posted September 29, 2019 Share Posted September 29, 2019 If you plan on tiling later then my understanding is that "ordinary" pva can become re "wetted" if you get leaks through the grout and cause the tiles to lift. (You can get waterproof pva). I used thinned down SBR as a dust sealer on the concrete. Firstly on the basis its waterproof, second it could be used as an alternative to the tanking primer. Worked really well as it was a couple of YEARS before I got round to tiling. Link to comment Share on other sites More sharing options...

nod Posted September 29, 2019 Share Posted September 29, 2019 Both fine for sealing Though I do think SBR is more versatile Link to comment Share on other sites More sharing options...
Onoff Posted September 29, 2019 Share Posted September 29, 2019 I think SBR varies a Hell of a lot in price. I use the Cementone one: https://www.screwfix.com/p/cementone-sbr-admixture-white-5ltr/91566 Link to comment Share on other sites More sharing options...

You can seal it any time 4 to 1 But keep Off it till it dries as any Whoever tiles will seal it again We normally ad SBR to each mix also Link to comment Share on other sites More sharing options...

Tiler will use p51 before tiling. Link to comment Share on other sites More sharing options...
wozza Posted October 11, 2019 Share Posted October 11, 2019 Interested in this as I about most likely having Cemfloor. Technical Datasheet for Cemfloor : https://cemfloor.co.uk/download/2641/ No information about sealing the floor - just says to lightly abrade the surface to clean off any building residue. Have you tried calling them for advice? Link to comment Share on other sites More sharing options...

Have you tried calling them for advice? I haven't asked my supplier because we had to have harsh words related to garage floor. I guess there is 4 factors to this:- 1. A sealer that is compatible to be used on cemfloor. 2. A sealer that will be long lasting to foot traffic. 3. A sealer that is compatible to a floor with UFH. 4. A sealer that will not be detrimental to tiling at a later stage or need significant remedial works before tiling. Link to comment Share on other sites More sharing options...

SiBee Posted October 15, 2019 Share Posted October 15, 2019 The SBR recommendation has been posted many times on forums I read and suppliers I have talked to about such a task as you are doing. Interesting to learn that SBR is SBR, doesn’t matter what brand name is on the tub so go cheap as you can find? Link to comment Share on other sites More sharing options...
vfrdave Posted June 28, 2020 Author Share Posted June 28, 2020 I didn't do anything regarding sealing the floors. Covered some with lino remnant. Kitchen floor has been covered and is largely ok. It has been a little dusty but nowhere near as bad as traditional sand and cement. Tile order going in this week. Link to comment Share on other sites More sharing options...
