    Screed over fresh concrete

    Is there anything I can do to remedy this. I'm at my wits end with it all. I'm a diyer so just need advice. Surely when people chop out old hearths they sometimes have to patch them up or raise the level

    Screed over fresh concrete

    Ok I see so really I need to chop it all out and start again. Just a thought but could I try and add a mix similar to render. No idea what mix is used for this but aren't thicknesses similar.

    Screed over fresh concrete

    I was thinking exactly the same regarding footings. Floor is suspended timber and I want the screed to finish at floor level. The current level of concrete is about 30mm below floor so I need to raise it by that

    Screed over fresh concrete

    I need to raise the level of freshly laid concrete. By about 30mm I Planned on laying 4.1 screed over it but I'm hearing that it needs to fully dry out before I can add the screed. If it is possible would I need to apply a cement slurry first

    Screed is this right

    Screed is this right

    I thought that sharp sand screed would result in a harder surface than soft sand is this not the case

    Screed is this right

    Ok so I laid it all at the same time with the screed going straight onto the concrete. So would you expect to be able to rub sand off it. Also if a wet it and rub I get a sandy/cement slurry as though it's not fully set but expected it to not do this after seven days.

    Screed is this right

    I have recently cast some concrete and finished the top off with about 30mm of sharp sand screed. The concrete was mixed 4.2.1 and the sand screed was 4.1. the issue is that I'm not sure that is hardening correctly. Its been laid for a week now and gives of sand when rubbed.hard I've added a...

    Finishing hearth

    Yes I had actually also considered that option too with quarry tiles . Also wondered if I could just screed the area with some heat resistant cement type product. I think my main concern with all the options (probably way overthinking it all ) is how whatever I use will stand up to the heat

    Finishing hearth

    Thanks again for the reply so basically (if I've read it correctly) your suggestion is to make a stepped hearth which is approx 18mm higher in the recess.tiles would then lay flush upto the higher level in the recess

    Finishing hearth

    Tiling after fitting will be difficult because it does as you say come right down to floor (hearth) level. Your suggestion to use Hardie was exactly my original plan ie would bed the board on the concrete to finish at the same level as the tiles. I was put off as I started looking at heat...

    Finishing hearth

    Thanks for the reply. Ok so because the Stove is inset type then the tiles will be hidden by the Stove.

(See my other post) I will screed the concrete off level with my floorboards (pic shows roughly how it will but will obviously be smoother and level with floor boards) the opening will then be bricked up to form a...

    Hearth reconstruction

    Little update.got the dpm in place and now all ready to pour concrete up to floorboard level. original lintel was poorly fitted. think they must have realised last min that the lintel was too short for the opening so stuck a couple of overhanging bricks in(suppose regs were very different in...
